Federal rule: hours over 40 in a workweek at 1.5 × the regular rate. A non-discretionary bonus raises the regular rate: (straight-time pay + bonus) ÷ hours. Some states also have daily overtime.

Your numbers stay on this device. The page link keeps your inputs, so a bookmark or shared link reopens these results.

Enter the hourly wage, the hours worked in the workweek and any non-discretionary bonus earned that week. The calculator splits regular and overtime hours, works out the overtime rate and the gross pay for the week. Change the threshold or multiplier if a contract or state rule is more generous. Nothing is stored or sent; the numbers stay in the page address so you can bookmark them.

How overtime is calculated

Under the federal Fair Labor Standards Act, a non-exempt employee who works more than 40 hours in a workweek is paid at least one and one-half times their regular rate for every hour over 40 (29 U.S.C. §207(a); 29 CFR 778.107). Overtime is counted per workweek: a fixed, recurring 168-hour period. Hours cannot be averaged across two weeks.

Gross pay = (hourly rate × hours up to 40) + (hourly rate × 1.5 × hours over 40). At $20 an hour and 46 hours, that is $20 × 40 = $800 plus $30 × 6 = $180, so $980 for the week.

Time and a half at common hourly rates
Hourly rate	Time and a half	Double time
$15.00	$22.50	$30.00
$18.50	$27.75	$37.00
$20.00	$30.00	$40.00
$25.00	$37.50	$50.00
$32.00	$48.00	$64.00

When a bonus changes the overtime rate

A non-discretionary bonus, such as a production, attendance or safety bonus promised in advance, is part of the regular rate (29 CFR 778.209). The regular rate becomes (straight-time pay + bonus) ÷ total hours, and the overtime premium is half of that rate for each overtime hour (the method in 29 CFR 778.110(b)).

Same worker, same 46 hours, plus a $46 production bonus: straight time is $920, the regular rate is ($920 + $46) ÷ 46 = $21.00, and the premium is $21 × 0.5 × 6 = $63. Gross pay is $920 + $46 + $63 = $1,029, not the $1,026 you get by adding the bonus to the $980.

46 hours at $20/hour, with and without a $46 bonus
Line	No bonus	$46 bonus
Straight time (46 h × $20)	$920.00	$920.00
Bonus	$0.00	$46.00
Regular rate	$20.00	$21.00
Overtime premium (6 h × ½ rate)	$60.00	$63.00
Gross pay	$980.00	$1,029.00

State rules and double time

Some states go further than the federal rule. California, for example, also requires time and a half after 8 hours in a workday and double time after 12 hours in a workday, according to the California Labor Commissioner's overtime FAQ (dir.ca.gov, checked 2026-10-01). This calculator applies a weekly threshold; for a daily rule, add up the daily overtime hours yourself or ask your payroll provider.

Sources, checked 2026-10-01: 29 U.S.C. §207 (law.cornell.edu), 29 CFR 778.107, 778.110 and 778.209 (ecfr.gov), and the California DLSE overtime FAQ.

Exempt salaried employees are not owed overtime; whether someone is exempt depends on their duties and salary, not their job title.
Paid time off and holidays usually do not count as hours worked toward the 40.
Discretionary gifts, such as an unannounced holiday bonus, are excluded from the regular rate.

Frequently asked questions

How do you calculate time and a half?

Multiply the hourly rate by 1.5. $20 an hour becomes $30 an hour for each overtime hour; $18.50 becomes $27.75.

How much is 46 hours at $20 an hour with overtime?

$980. Forty hours at $20 is $800 and six overtime hours at $30 is $180.

When does overtime start?

Under federal law, after 40 hours worked in a workweek. Some states, such as California, also count hours over 8 in a single workday.

Do bonuses count toward overtime pay?

Non-discretionary bonuses do. They raise the regular rate for the week, so the overtime premium goes up. A $46 bonus on a 46-hour week at $20 raises the regular rate to $21 and the week to $1,029.

Is this payroll or legal advice?

No. It is an estimate for planning a schedule or checking a pay stub. Your payroll provider, the Department of Labor or your state labor office has the final word on what is owed.
