Variable Compensation: A Small Business Guide to Plans
What variable compensation is and how to build a plan. The types, a 6-step build, non-sales examples, and the overtime rule that catches small employers.
Variable Compensation
How to build a plan that changes behavior without accidentally underpaying overtime
This guide shows you how to reward results with variable pay without getting the overtime math wrong, a mistake that is easier to make than it sounds. A founder I know set up what he thought was a simple bonus. Hit the weekly quality target, get $100. He announced it at a Monday meeting, everyone liked it, and it worked. Output went up.
What he did not know is that by announcing it in advance, he had created a nondiscretionary bonus, which under the FLSA (the federal Fair Labor Standards Act) has to be folded into the regular rate used to calculate overtime. Every non-exempt employee who earned that bonus in a week they worked overtime was underpaid, quietly, for months. The bonus was $100. The exposure was considerably more.
Variable compensation is one of the most powerful tools a small business has, precisely because it converts a fixed cost into a cost that only appears when the result does. But it interacts with wage law in ways that are not obvious, and almost every guide on this topic is written for a sales organization with a comp analyst.
This one is written for the small business where the owner runs HR off the side of their desk. It covers what variable compensation is, the types, how to build a plan, non-sales examples, and the compliance rules that turn a good idea into back wages.
What Is Variable Compensation?
Variable compensation is any pay that changes based on performance, results, or company success, paid on top of a fixed base salary or wage. Bonuses, commissions, profit sharing, and incentives are all variable pay. It is also called incentive pay, pay for performance, or simply variable pay.
The distinction that actually matters is not the label but the logic. Fixed pay buys someone's time. Variable pay buys a specific result. Blur that line and you get one of two bad plans. One pays out regardless of performance, which is just a salary with extra paperwork. The other withholds pay for outcomes people cannot control, which is just a morale problem with a spreadsheet.
Fixed Pay vs Variable Pay
Both are compensation, but they behave completely differently as a business decision. Fixed pay is guaranteed whatever happens; the variable portion is paid only when a defined result arrives.
| Fixed Pay | Variable Pay | |
|---|---|---|
| Guaranteed regardless of results | ||
| Predictable for budgeting | ||
| Cost appears even in a bad year | ||
| Directly rewards a specific outcome | ||
| Can be adjusted without cutting anyone's base | ||
| Usually requires a written plan document | ||
| Can raise overtime owed to non-exempt staff |
The bottom two rows are the ones nobody talks about, and they are the ones that create liability. Variable pay needs documentation that fixed pay does not, and most forms of variable pay change the overtime math for non-exempt employees. We come back to both.
Types of Variable Compensation Plans
Six forms cover essentially everything a small business would realistically use: bonuses, commissions, profit sharing, spot awards, team and gainsharing incentives, and equity or long-term incentives.
Notice that only one of these, the discretionary spot award, stays outside the overtime calculation by being decided after the fact. Bonuses and team incentives announced in advance or tied to a formula become nondiscretionary and enter the regular rate, as commissions always do. That is not a reason to avoid them. It is a reason to know it before you build the plan.
Profit sharing and stock options can also stay out of the regular rate, but by a different route: they have to meet conditions in section 7(e) of the FLSA. A profit-sharing plan qualifies under the federal regulation at 29 CFR Part 549 only if, among other tests, it is written, paid solely from profits, and sets no share by attendance, output, or efficiency. Stock options face separate tests, including timing and price.
Annual Incentive Plans
An annual incentive plan is the formal version of the yearly bonus: a target payout expressed as a percentage of base salary, earned against results measured over the fiscal year, and paid once the books close. It suits salaried staff because it runs on the rhythm the financials already follow.
Four decisions define one. The target percentage by role, which should rise with how much of the result the person controls. The weighting between company results and individual goals. The payout scale, which is covered further down. And the eligibility rules: who joins mid-year, how a partial year is prorated, and what happens to someone who resigns before payout.
That last rule deserves a deliberate answer rather than a default. A clause requiring the employee to be on the payroll on the payout date is common. It is also the clause most likely to be argued about, because a bonus that has already been earned can be treated as wages. Decide it inside the plan document, and have counsel read it if the amounts are meaningful.
The annual shape carries one more wrinkle. A nondiscretionary annual bonus paid to a non-exempt employee has to be apportioned back across the workweeks of the year, with the overtime premium recalculated for each of them. An annual plan limited to exempt staff never triggers that recalculation, which is part of why the structure stays manageable.
A Commission Plan Example
Commission is the form most people picture when they hear variable pay, so here is one on paper. A rep earns a $50,000 base plus 6 percent of collected revenue on new accounts. The commission is earned when the customer pays rather than when the contract is signed, and it is paid on the fifteenth of the following month.
Four terms carry that whole plan, and each is doing a job. The base sets the floor. The rate and the revenue definition set the calculation. The earning moment decides who is owed what when a customer signs and then never pays, which is the clause disputes actually turn on. The payment date ends the argument about timing.
Then write down the awkward answers: what a rep who resigns mid-month is owed on deals already collected, whether a refund reverses a commission already paid, and how split accounts and house accounts (customers the company keeps for itself) are handled. Settle them before the first hire, because a rule written after a dispute reads as a rule invented to win it. The mechanics of rates and draws sit in the guide to commission pay.
Does a Small Business Actually Need One?
Not always. Variable pay is genuinely useful in three situations and actively counterproductive outside them.
It works when the outcome is countable and the person controls it. A salesperson who closes deals, a technician who completes jobs without callbacks, a kitchen that controls food cost. The employee can see the number move when they act, which is the entire mechanism.
It works when you need cost flexibility. A small business with uneven revenue can promise a smaller base plus a real upside, and only pay the upside in the years that earned it. That is a legitimate risk-sharing arrangement, provided the base is honest and the upside is achievable.
It works when you want to signal what matters. A plan is a very loud statement about what the company cares about, louder than any all-hands meeting. Whatever you attach money to is what people will optimize for, which is also the danger.
It does not work when the person cannot move the number. A receptionist's bonus tied to company revenue is a lottery ticket, not an incentive, and it produces cynicism rather than effort. If the connection between the behavior and the payout requires a slide to explain, the plan will not change behavior.
The Overtime Trap
This is the most important section on this page, because a bonus can raise the overtime you owe, retroactively, on hours already worked.
For non-exempt employees, overtime is calculated on the regular rate, which is not simply the base hourly wage. In Fact Sheet #56A, the US Department of Labor (DOL) explains that the regular rate includes all remuneration for employment except a specific statutory list of exclusions, computed as total compensation for the workweek divided by hours worked.
Whether a particular bonus raises your overtime bill comes down to one distinction. Per DOL Fact Sheet #56C, a bonus is discretionary only if all three conditions are met:
| Test | What It Requires | Where Small Employers Fail It |
|---|---|---|
| Sole discretion over whether to pay | You retain the right to decide, up to at or near the end of the period, whether the bonus gets paid at all. | Announcing a bonus program in advance forfeits this. Paying the same bonus every year can too, once the pattern reads as an implied promise. |
| Sole discretion over the amount | You retain the right to decide the amount, up to at or near the end of the period. | Any formula, any 'hit X and get $Y,' any published payout table destroys this test immediately. |
| No prior contract, agreement, or promise | The payment is not made under any arrangement that leads the employee to expect it regularly. | The Monday meeting where you announced the target counts as a promise. Last year's bonus, repeated on the same terms, can count as an implied one. |
Read the DOL's last point twice, because it is the one that catches everyone. Founders reason: I could always decide not to pay it, therefore it is discretionary. That is not the test. If you announced it and they expect it, it is nondiscretionary, whether or not you technically retained a veto.
Run the three tests on paper once per payment, before the first payout, and keep the answer. The record below is what you want in the file if someone asks two years later why the regular rate was or was not recalculated. It takes about ten minutes and it is the difference between a deliberate decision and a discovery.
The Bonus Overtime Math
Here is what the founder in the introduction should have calculated. Take a non-exempt employee at $20 an hour who works 45 hours in the week and earns the announced $100 quality bonus.
The bonus raised her regular rate from $20.00 to $22.22, which raised the half-time premium on her five overtime hours from $50.00 to $55.55. That is small on one paycheck.
Multiply that difference by everyone in the plan and by every overtime week across the two-year FLSA lookback (three years for a willful violation), which is how far back a wage claim can reach. Then add the equal amount in liquidated damages the statute provides, which can double what you owe, and it stops being small.
Note the shape of the calculation: because straight time on all 45 hours is already counted in step three, only the additional half is owed on the overtime hours. This is the same mechanic that governs piece rate and day rates.
The weekly bonus above is the simple case. Under the federal overtime rules at 29 CFR 778.209, a bonus covering a period longer than a week, like a quarterly or annual bonus, has to be apportioned back across the workweeks it was earned in, and the overtime premium recalculated for each of those weeks. This is genuinely tedious, which is why it gets skipped, and skipping it is exactly the violation.
Get It in Writing
A variable compensation plan that exists only in conversation will eventually be remembered differently by the two people who were in it, and the disagreement will surface at the exact moment money is supposed to change hands.
In several states a written plan is also a legal requirement. California Labor Code section 2751 provides that where the contemplated method of payment involves commissions, the contract shall be in writing and shall set forth the method by which the commissions shall be computed and paid. The employer must give the employee a signed copy and obtain a signed receipt.
Two details in that statute deserve attention. First, it turns on the substance of the payment, not what you call it: a payment based proportionally on the value of a sale is a commission whether you label it a bonus or not. Second, if the plan changes, you need a new signed agreement. Initial compliance is not permanent compliance.
There is also a federal interaction worth knowing if you have exempt employees, the ones not entitled to overtime. Per DOL Fact Sheet #17U, employers may use nondiscretionary bonuses and incentive payments, including commissions, to satisfy up to 10 percent of the standard salary level, provided they are paid at least annually.
At the $684 weekly threshold, those nondiscretionary payments can cover at most $68.40 per week, so the employee must still receive at least $615.60 per week on a salary basis. If the total falls short over the 52-week period, you get one pay period to make a catch-up payment, and if you do not, the exemption fails for the entire preceding year.
How to Build a Variable Compensation Plan in Six Steps
Building a variable compensation plan takes six steps, in this order: choose the outcome, confirm the person controls it, pick the form and size, decide whether it is discretionary, write it down and get it signed, and set up payroll before the first payout.
Incentive Plan Design: Pay Mix and the Payout Curve
Two numbers turn those six steps into an actual plan. Pay mix is how target total compensation splits between base and variable. The payout curve is what the plan pays at each level of attainment. Plans that feel unfair to the people inside them have usually gotten one of the two wrong.
Pay mix follows control. A closer who personally decides whether a deal lands can carry a 70/30 or 60/40 split between base and variable, because the variable portion is genuinely within reach. An operations or administrative role influences the result without determining it, so the variable share belongs somewhere in the range of five to fifteen percent of base. A heavy mix on someone who cannot move the number converts their salary into a gamble.
The curve then sets the shape: a threshold below which nothing pays, a target that pays the full number, and above the target either a cap or an accelerator (a higher payout rate on the excess). The table below is a common shape rather than a rule, and the only version that matters is the one you can defend to the person earning it.
| Attainment against target | What the plan pays | What that step is for |
|---|---|---|
| Below threshold, under 80 percent | Nothing | Keeps the business from paying for a result that did not arrive |
| Threshold, at 80 percent | Half the target payout | Keeps someone in the game after a slow start instead of writing off the period |
| Target, at 100 percent | The full target payout | The number the plan was designed around, and the one people remember |
| Above target, to 120 percent | Target plus an accelerator on the excess | Pays properly for the results that are genuinely hard to reach |
| Above 120 percent | A stated cap, or uncapped by deliberate choice | Limits a windfall from one unusual deal, at the cost of some upside |
Two cautions on that curve. A cap tells your best performer exactly when to stop selling, so cap on purpose or not at all. And every figure in the table becomes nondiscretionary the moment employees see it, so run the three tests before you publish the curve rather than after the first payout.
Plans That Are Not Sales Commissions
Variable compensation works outside sales too, and most small businesses are not sales organizations. Here are four structures for businesses where nobody carries a quota.
The common thread: each plan pays on the number that actually decides whether that specific business makes money, and each one pays the people who genuinely move it. That is the whole design principle. It is not about copying a software company's sales compensation plan at a smaller scale.
Common Variable Compensation Mistakes
The six variable compensation mistakes below fall into three groups: overtime math nobody recalculated, plan terms nobody wrote down, and targets people cannot act on.
| Mistake | What Happens | The Fix |
|---|---|---|
| Not folding a nondiscretionary bonus into the regular rate | Every non-exempt employee who earned the bonus in an overtime week was underpaid. The lookback is 2 years, 3 for willful, and liquidated damages can double it. | Determine discretionary vs nondiscretionary before you launch, and configure payroll to recalculate the regular rate on payout. |
| Assuming 'I could choose not to pay it' means discretionary | It does not. The DOL says explicitly that having the option not to pay a promised bonus does not make it discretionary. | Apply all three tests: sole discretion over payment, sole discretion over amount, and no prior promise. Fail one and it is nondiscretionary. |
| No written plan | The terms are remembered differently by each side, and the disagreement arrives exactly when money is due. In some states, for commissions, this is also a violation. | Write it down. Eligibility, target, calculation, when earned, when paid, and what happens on termination. Get it signed. |
| Leaving 'earned' undefined | The employee believes they earned it at signature, you believe at collection, and now you are trying to claw back wages, which you generally cannot do. | Define the earning moment explicitly, with an example. Ambiguity is generally construed against the drafter. |
| Too many metrics | Nobody can hold seven targets in their head while working, so the plan stops influencing behavior and becomes an accounting exercise. | One metric, two at most. If you cannot explain the plan in one sentence, the employee cannot act on it. |
| Paying on outcomes people do not control | Cynicism. A payout that feels random is not an incentive, and it can be worse than no plan at all because it signals that effort is unrelated to reward. | Pay variably only on what the individual or their team genuinely influences. |
Running a Plan Without an HR Team
The compensation design is the interesting part. The reason plans fail at small companies is almost never design. It is that the plan lives in a Slack message, the targets live in someone's head, nobody tracks attainment until payout day, and the signed agreement does not exist.
| What Needs a Home | Why | What Happens Without It |
|---|---|---|
| The signed plan document | Eligibility, targets, calculation, and the definition of earned, acknowledged by the participant. Required by law for commissions in several states. | The terms are disputed at payout, and the ambiguity is generally construed against you. |
| Each employee's targets and attainment | Someone has to be able to answer, mid-quarter, what a given person is tracking against. Not just on payout day. | Attainment gets reconstructed from memory at payout, which is when disputes start and when the plan stops influencing anyone's behavior. |
| The discretionary vs nondiscretionary determination | It drives whether payroll has to recalculate the regular rate for overtime. This is a payroll configuration, not a philosophy. | Non-exempt employees get underpaid for overtime, silently, for as long as the plan runs. |
| The re-signing loop when the plan changes | Plan terms change over time, and each change generally needs a new signed agreement, not an email. | You are operating under an old agreement while paying under a new one, which is the worst of both. |
Three of those four fit in one workbook, and the workbook is worth building on the day the plan launches rather than the week of the payout. The first sheet answers what someone is tracking against in the middle of the period. The second is the payout register, with the columns that force the overtime question to be answered before money moves. The third is the signature log that tells you who is currently signed up to which version of the plan.
| A | B | C | D | E | F | G | H | I | |
|---|---|---|---|---|---|---|---|---|---|
| 1 | Employee | Plan name | Period | Metric being paid on | Target | Actual to date | On track | Updated on | Notes |
| 2 | [Replace this row with your first participant] | [Plan name] | [Q or month] | [One metric] | |||||
| 3 | |||||||||
| 4 | |||||||||
| 5 | |||||||||
| 6 | |||||||||
| 7 | |||||||||
| 8 | |||||||||
| 9 |
This is where FirstHR fits. Each employee profile stores the plan and the targets as documents, next to the FLSA status that tells you whether the overtime recalculation applies. E-signature and document management capture the signed plan and the re-signed version when terms change, which is the artifact several states actually require. Task workflows put the plan review and the payout calculation on a date with an owner, rather than leaving them to whoever remembers.
FirstHR is not a payroll engine and does not calculate your regular rate or run the payout; that stays with your payroll provider, and you should confirm with them that nondiscretionary bonuses are folded into overtime correctly before your first payout. What FirstHR holds is the plan, the acknowledgment, the targets, and the paper trail behind them.
None of this is legal advice, and variable pay sits at the intersection of wage law, tax, and state-specific commission rules. If your plan involves commissions, deferred payouts, or equity, have counsel look at the document before anyone signs it.
Frequently Asked Questions
What is variable compensation?
Variable compensation is the share of an employee's pay that rises or falls with performance, results, or how well the company does, and it comes in addition to a fixed salary or hourly wage. Bonuses, commissions, profit sharing, spot awards, and equity all count. Its defining trait is that it is conditional: nothing is earned until a specific result happens. A salary or wage pays for someone's time, while variable pay pays for an outcome, which is why people also call it incentive pay or pay for performance.
What is the difference between fixed and variable compensation?
Fixed compensation is guaranteed and predictable: a salary or an hourly wage the employee receives regardless of results. Variable compensation is conditional and fluctuates: it is paid only when a defined target is met. The two together make up total compensation. The practical difference for an employer is risk. Fixed pay is a cost you carry in a bad year. Variable pay is a cost that only appears when the outcome it rewards actually occurred, which is what makes it attractive to small businesses with uneven revenue.
What is a variable compensation plan?
A variable compensation plan is the written document that sets out who can earn variable pay, the result each person has to reach, how the payout amount is worked out, and when the money is paid. It is different from a bonus. The bonus is the payment itself, and the plan is the rule that decides whether that payment happens. Without the document, the terms exist only as each side recalls them, and two people rarely recall a pay promise the same way, least of all on payout day.
Is variable compensation taxed differently?
It is taxed, but withholding often works differently. IRS Publication 15 treats bonuses, commissions, and awards as supplemental wages. When they are paid or identified separately from regular pay, an employer that withholds income tax from the employee's regular wages may apply a flat 22 percent federal rate instead of the normal withholding tables. Supplemental pay above $1 million in a year is withheld at 37 percent. This frequently makes it look like the bonus was taxed more heavily, when in reality it was simply withheld differently and reconciles at tax filing. The payment is ordinary income either way, and it is subject to Social Security and Medicare like any other wages.
Do bonuses affect overtime pay?
Yes, and this is the single most expensive mistake small employers make with variable pay. Under the Fair Labor Standards Act (FLSA), a nondiscretionary bonus, meaning one you announced in advance or tied to a formula, must be included in the regular rate used to calculate overtime for non-exempt employees. It raises the regular rate, which raises the overtime premium owed. A truly discretionary bonus, where whether to pay and how much remain your sole decision until near the end of the period, can be excluded.
What is the difference between a discretionary and nondiscretionary bonus?
A discretionary bonus stays entirely your call, while a nondiscretionary bonus is one employees were led to expect. Department of Labor Fact Sheet #56C sets three conditions, and only a bonus that meets every one of them counts as discretionary: you alone decide whether to pay it, you alone decide how much, and you make both calls at or near the end of the period instead of promising the payment in advance. Missing even one makes the bonus nondiscretionary. Bonuses set by a predetermined formula, production bonuses, attendance bonuses, safety bonuses, and retention bonuses all land on the nondiscretionary side, because employees know about them ahead of time and count on them. Keeping the right to cancel a bonus you already promised does not turn it into a discretionary one.
Do I need a written variable compensation plan?
Legally it depends on the state and the type of pay, but practically the answer is always yes. California Labor Code section 2751 requires commission agreements to be in writing, setting out the method by which commissions are computed and paid, with a signed copy given to the employee and a signed receipt kept by the employer. New York requires written terms signed by both sides for commissioned salespeople, and other states have their own commission rules. Beyond the legal requirement, a written plan is what prevents the argument about what was promised, and that argument is far more common than the audit.
How much should variable compensation be?
It depends entirely on the role and how much control the person has over the outcome. Sales roles commonly run a heavy variable mix because the individual controls the result. Operations and administrative roles call for a much smaller variable component, because they influence outcomes rather than determine them, and five to fifteen percent of base is a sensible place to start. The design question is not what percentage is standard. It is how much of the result this person actually controls, and the answer tells you what portion to pay variably.
Can variable pay count toward the exempt salary threshold?
Partially. For employees classified as exempt, Department of Labor rules let nondiscretionary bonuses, incentive payments, and commissions cover as much as 10 percent of the standard salary level, as long as they are paid at least once a year. With the threshold at $684 a week, those payments can supply up to $68.40 of it, so the salary itself still has to reach at least $615.60 each week. If salary plus these payments comes up short when the 52-week period ends, the employer gets one pay period to make up the difference with a catch-up payment; without it, the employee loses the exemption for the whole year.
Can I take back a commission that was already earned?
Generally no, and trying is where employers get into serious trouble. When a commission has been earned under the plan's terms, the law treats it as wages, and an employee cannot be made to forfeit earned wages. That puts all the weight on how the written plan defines the word earned. Spell out the exact moment a commission becomes earned: when the sale closes, when the product is delivered, or when the customer actually pays. An unclear plan is generally read against the employer who drafted it, and taking back money an employee reasonably believed was already theirs is a quick way to end up facing a wage claim.
