Your overtime rate is not always your hourly wage. Promised bonuses must be folded into the regular rate before the 1.5 multiplier, which raises every overtime hour. Surprise bonuses are the exception. Here is how to tell them apart and do the math.

Nondiscretionary bonuses, such as production and attendance bonuses you were promised or could expect, must be included in the regular rate for overtime. Add the bonus to the week's pay, divide by hours worked, and apply the 1.5 multiplier to the result. Discretionary bonuses, where the employer decides both whether and how much to pay near the end, are excluded.
A nondiscretionary bonus is one the employee can expect: it was promised in advance, it follows a formula or plan, or it is paid for hitting production, attendance, quality, or efficiency targets. These bonuses are part of the regular rate, full stop. A discretionary bonus is one where the employer keeps discretion over both the fact of payment and the amount until at or near the end of the period the bonus covers. Think of a genuine year end surprise decided in December with no prior promise and no formula.
The label on the bonus does not decide. An employer that calls a quarterly production payout "discretionary" but pays it to everyone who hits a published target is paying a nondiscretionary bonus, and it belongs in the regular rate. The Department of Labor looks at the facts: was it promised, was there a formula, could employees reasonably expect it?
Bonuses are only part of the story. The regular rate is total pay for the workweek, minus the statutory exclusions, divided by total hours worked. That total also sweeps in shift differentials, commissions, and piece rate earnings. The exclusions include pay for time not worked like vacation and sick pay, reimbursed business expenses, genuinely discretionary bonuses, gifts, and premium pay that already counts as overtime. DOL Fact Sheet 56A lists the full set.
A bonus paid monthly or quarterly cannot be dumped into a single week. It is spread back over the workweeks it covers, raising the overtime owed in each of those weeks. The standard method: divide the bonus by the total hours worked in the covered period to get the per hour increase in the regular rate, then for each overtime hour in the period add half that increase as extra premium. Here is that method twice.
You earn $20 per hour, work 44 hours in a week, and earn a $400 monthly attendance bonus covering 4 weeks. This week you worked 44 hours, and the month totals 176 hours.
Without the bonus the premium would have been 0.5 × $20 × 4 = $40. The bonus added $4.55 of overtime for this one week, and similar amounts to the other three weeks of the month.
You earn an $800 weekly salary and a $1,500 quarterly production bonus. Over the 13 week quarter you worked 600 total hours, including 30 overtime hours.
The $37.50 is owed on top of the overtime already paid from the salary alone. When the quarterly bonus lands, payroll must go back and recompute each overtime week, which is the step most often skipped in practice.

Yes. A production bonus you were promised and earned is nondiscretionary, so it must be included in the regular rate before overtime is computed. An employer that computes overtime from the base wage alone is underpaying.
The employer must keep discretion over both whether to pay it and how much to pay, right up until near the end of the period. If the bonus was promised in advance or is tied to a formula, it is nondiscretionary even if the employer calls it discretionary.
It is spread back over the workweeks it covers, raising the regular rate of each of those weeks. The common method is to divide the bonus by the total hours worked in the covered period, then add half that amount per overtime hour for the overtime hours in those weeks.
Yes. Shift differentials, commissions, and piece rate earnings are all part of total pay for the week and raise the regular rate, exactly like nondiscretionary bonuses.
Probably not. Labels do not decide. If employees can reasonably expect the bonus and it is paid under a known formula or practice, the Department of Labor treats it as nondiscretionary and it belongs in the regular rate.
