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
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 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 5-to-50-person 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. The moment you blur that, you get plans that pay out regardless of performance, which is just a salary with extra paperwork, or plans that withhold pay for outcomes people cannot control, which is just a morale problem with a spreadsheet.
Fixed Pay vs Variable Pay
Both are compensation. They behave completely differently as a business decision.
| 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 hourly employees. We come back to both.
Types of Variable Compensation Plans
Six forms cover essentially everything a business with 5 to 50 employees would realistically use.
Notice that only one of these, the discretionary spot award, reliably stays outside the overtime calculation. Everything else, if it is announced in advance or tied to a formula, becomes nondiscretionary and enters the regular rate. That is not a reason to avoid them. It is a reason to know it before you build the plan rather than after.
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. 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. Tying a receptionist's bonus to company revenue is not an incentive, it is a lottery ticket, 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 and the one almost every competing article omits.
For non-exempt employees, overtime is calculated on the regular rate, which is not simply the base hourly wage. Per DOL Fact Sheet #56A, 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. Which means a bonus can raise the overtime you owe, retroactively, on hours already worked.
Whether it does 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. So does paying the same bonus every year until people expect it. |
| 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. So does last year's bonus, repeated. |
Read that last sentence 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.
The Bonus Overtime Math
Here is what the founder in the introduction should have calculated. Non-exempt employee at $20 an hour, 45 hours in the week, earning 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. Small on one paycheck. Multiply it by everyone in the plan, by every overtime week, across the two-year lookback the FLSA allows (three for willful violations), and add liquidated damages that can double the award, 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 overtime guide covers the regular rate across every pay structure, and the bonus guide covers how bonuses are taxed once you have paid them.
One more wrinkle worth knowing. 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 this is not just prudent, it is required. 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. 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, that is $68.40 per week, meaning 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
Plans That Are Not Sales Commissions
Nearly every article on variable compensation assumes you are running a sales org. Most small businesses are not. Four real structures for businesses where nobody has 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 SaaS comp plan at a smaller scale.
Common Variable Compensation Mistakes
| 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 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 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 | Plans change annually. 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. |
This is where FirstHR fits. Employee profiles hold each person's plan, eligibility, and targets so attainment is visible rather than reconstructed at payout. 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. The total compensation guide covers how variable pay fits into what an employee actually costs.
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 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, spot awards, and equity are all forms of variable pay. The defining feature is that it is conditional: the employee earns it only if something specific happens. Fixed pay compensates someone for their time. Variable pay compensates them for an outcome, which is why it is also called 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 defining who is eligible for variable pay, what they have to achieve to earn it, how the payout is calculated, and when it is paid. A plan is not the same thing as a bonus. A bonus is a payment; a plan is the rule that produces it. Without a written plan, the arrangement lives in someone's memory, which means it will eventually be remembered differently by the two parties, usually at the moment money is supposed to change hands.
Is variable compensation taxed differently?
It is taxed, but withholding often works differently. Bonuses and most incentive payments are supplemental wages, which employers may withhold on at a flat federal supplemental rate rather than using the employee's normal withholding tables. 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 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 you retain sole discretion over both whether to pay and how much until near the end of the period, can be excluded.
What is the difference between a discretionary and nondiscretionary bonus?
A bonus is discretionary only if all three conditions are met: you have sole discretion over whether to pay it, sole discretion over the amount, and the decision is made at or near the end of the period rather than promised in advance. Fail any one and it is nondiscretionary. Bonuses based on a predetermined formula, production bonuses, attendance bonuses, safety bonuses, and retention bonuses are all nondiscretionary, because employees know about them and expect them. The fact that you have the option not to pay a promised bonus does not make it discretionary.
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 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. 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 typically carry a much smaller variable component, often in the range of five to fifteen percent of base, because they influence outcomes rather than determine them. The design question is not what percentage is standard. It is how much of the result this person actually controls, and pay them variably on that portion.
Can variable pay count toward the exempt salary threshold?
Partially. Under DOL rules, 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 that is $68.40 per week, meaning the employee must still receive at least $615.60 per week on a salary basis. If the total falls short at the end of the 52-week period, the employer has one pay period to make a catch-up payment or the exemption fails for the entire year.
Can I take back a commission that was already earned?
Generally no, and this is where employers get into serious trouble. Once a commission is earned under the terms of the plan, it is wages, and wages cannot be forfeited. This is why the definition of earned matters so much in the written plan. Define precisely when a commission becomes earned, whether that is at the close of the sale, at delivery, or when the customer actually pays. Ambiguity here is resolved against the employer, and clawing back money an employee reasonably believed they had earned is a fast route to a wage claim.
