Time and a Half: How to Calculate It Correctly

Time and a half sounds like the simplest calculation in payroll. Take the hourly rate, multiply by one and a half, apply to hours over forty. Most small businesses do exactly that and most small businesses that pay any kind of bonus or shift differential are underpaying.

The reason is in the definition and it is easy to miss. The multiplier applies to the regular rate, and the regular rate is not the hourly wage. It is everything the employee earned that week for working, divided by the hours they worked, which means a $2 shift differential or a small production bonus quietly raises every overtime hour in the period.

This covers what goes into the regular rate, four worked examples including the salaried non-exempt case people get wrong, the states with daily overtime, what time and a half is not owed for, and the new reporting line on the W-2. I build the people and records tooling for businesses without an HR department at FirstHR, and FirstHR is an onboarding and HR platform rather than a payroll provider. This is general information, not legal advice.

What Time and a Half Is

Time and a half is a pay rate of one and a half times an employee's regular rate, owed for overtime hours. Federal law sets the trigger at more than 40 hours worked in a workweek for employees who are not exempt.

Two structural points follow. Overtime is calculated per workweek and never averaged across two weeks, so an employee who works 50 hours one week and 30 the next is owed overtime for the first week regardless of the two-week total. And the workweek is whatever fixed seven-day period you established, which does not have to start on a Monday but does have to be consistent (29 U.S.C. 207).

When It Is Owed

The obligation attaches to hours worked by a non-exempt employee, and the classification question comes first because it decides everything after it.

Exempt status requires both a qualifying duties test and a salary at or above the federal threshold, which stands at $684 per week following the Department of Labor's restoration of the earlier salary levels in May 2026 after the 2024 rule was vacated. Paying somebody a salary does not by itself make them exempt, and this is the misconception that produces the largest back-pay exposures at small companies.

Hours worked is the other term doing real work. It means time the employee was actually working, which excludes paid time off and holiday pay for days not worked. An employee who takes eight hours of holiday pay and works 36 hours has 36 hours worked and no overtime, even though the paycheck shows 44 paid hours.

The Regular Rate, Which Is Not the Hourly Wage

This is the sentence that costs money. The regular rate is total straight-time compensation for the week divided by hours worked, and a great many pay components fold into it (29 CFR 778.109).

The item on the left that catches small employers hardest is the nondiscretionary bonus, because almost every bonus a small business pays is nondiscretionary. If it was promised, announced, or driven by a formula, it belongs in the regular rate for the period it covers, and the overtime already paid for those weeks has to be recalculated upward.

The other frequent error runs the opposite way: treating holiday and vacation pay as though it counted toward the 40-hour threshold. It is pay for time not worked, it does not enter the regular rate, and it does not push anybody into overtime.

Four Worked Examples

The arithmetic is easier to see than to describe, and the third example is the one worth reading twice.

In the third case the employer approved a $92 bonus and spent $158. That gap is not a penalty; it is the correct calculation, and it is invisible to anybody who thinks of a weekly bonus as a fixed cost. Where the bonus covers a longer period, it is apportioned across the weeks it relates to and each week's overtime is recalculated (29 CFR 778.208).

Salaried Non-Exempt Employees

A salary is a way of paying somebody, not a classification. An employee who is paid a salary but does not meet a duties test, or is paid below the federal threshold, is non-exempt and is owed overtime like anybody else.

The calculation converts the salary to an hourly regular rate. Where a weekly salary is intended to cover 40 hours, divide by 40. The salary has already paid straight time for those hours, so the overtime hours are paid at one and a half times the resulting rate.

When Time and a Half Is Not Owed

Several situations that feel like they should trigger a premium do not, at least not federally.

The first two rows produce the most disagreements and the answer is not the one employees expect. Holiday and weekend premiums are extremely common, entirely voluntary, and become binding once you have promised them in a handbook or a contract.

Daily Overtime States

Federal law sets a floor and several states go beyond it, most significantly by requiring overtime on a daily rather than only a weekly basis.

Where a state requires overtime after a set number of hours in a day, an employee can be owed a premium in a week where they never reached 40 hours. Some states add a double time tier beyond a further daily threshold, and some require a premium on the seventh consecutive day worked. Where federal and state rules both apply, the employee receives whichever calculation produces the greater payment.

For a business operating in more than one state this is not a detail that can be handled with one company-wide rule, and a scheduling practice that is entirely lawful in one location can create daily overtime in another. The specific thresholds should be confirmed against the state labor agency rather than a summary.

The New W-2 Line

A federal deduction now exists for qualified overtime compensation, and the part that matters to an employer is not the deduction itself but the reporting it requires.

Qualified overtime compensation means the premium portion, the amount paid above the employee's regular rate, rather than the whole overtime payment. In time and a half, it is the half. Employers are required to report that figure separately on the W-2 beginning with tax year 2026, which means the premium has to be tracked as its own number rather than folded into gross wages (Internal Revenue Service).

Two practical consequences. Payroll systems need to be producing that split now rather than in January, because reconstructing a year of premium amounts retroactively is unpleasant. And withholding is unchanged: the deduction is claimed by the employee on their return, so nothing about the paycheck calculation changes.

Where Small Employers Get This Wrong

Six patterns, and the first two account for most of the money.

Multiplying the base hourly wage instead of the regular rate is first. Any shift differential, commission, or nondiscretionary bonus makes this wrong, and it is wrong every single overtime hour.

Not recalculating after a nondiscretionary bonus is second. It is the same error arriving later, and it accumulates across every overtime hour in the bonus period.

Averaging hours across two weeks is third. Fifty hours followed by thirty is not two forty-hour weeks; it is one week with ten hours of overtime owed.

Treating salaried as exempt is fourth. Exemption needs a duties test and a salary at or above the federal threshold, and the salary alone establishes nothing.

Counting holiday and vacation pay toward the 40 is fifth, which is the one error that runs in the employee's favour and still needs fixing, because inconsistency is its own problem.

And offering comp time in place of overtime is last. It is available to public sector employers under specific conditions and generally not to private ones, and the version most small businesses have in mind is not permitted. Managing hours within the same workweek is the lawful equivalent.
