See your time-and-a-half rate in a second. Enter your hourly rate and how many overtime hours you're working, and get your 1.5× and 2× rates plus the overtime pay.
Gross pay before taxes. Time-and-a-half (1.5×) is the US federal minimum overtime rate; double time (2×) is set by some employers, contracts, or state rules.
Time-and-a-half means 1.5× your normal hourly rate. So a $20/hour rate becomes $30/hour for overtime. Double time (2×) — $40/hour here — is used by some employers for holidays or hours beyond a second threshold, but it isn't required by US federal law.
Time-and-a-half rate = hourly rate × 1.5
Time and a half is the simplest arithmetic on this site — one number times 1.5 — and almost every overtime dispute is about the number being multiplied, never the multiplier. The Department of Labor's rule is that covered, non-exempt employees "must receive overtime pay for hours worked in excess of 40 in a workweek at a rate not less than time and one-half their regular rates of pay." The regular rate is not the rate on your offer letter: it is total pay for the week divided by hours actually worked.
So this calculator gives you a floor. If your pay is a flat hourly rate and nothing else, the floor is the answer. If you also earn a shift differential, a non-discretionary bonus or a piece rate, your regular rate that week is higher than your posted rate and so is the overtime owed. What may be left out is a narrow list: expense reimbursements, discretionary bonuses, gifts, and true premiums already paid for weekend or holiday work.
The calculator opens at $20 an hour and 10 overtime hours. Time and a half is 20 × 1.5 = $30 an hour. Double time, shown alongside, is 20 × 2 = $40. The ten overtime hours therefore pay 30 × 10 = $300.
In the context of a full week: 40 regular hours at $20 is $800, plus the $300 of overtime, so the week's gross is $1,100 for 50 hours — a blended $22 an hour. That blended figure is what the labour line in the job file will show. Paying those ten hours at straight time would pay $200 and leave the employee $100 short; the missing $100 is the "half" in time-and-a-half, which is why wage claims are computed as a half-time premium rather than a re-run of the whole payroll.
Now add the wrinkle. Suppose the same week carried a $50 non-discretionary production bonus. Straight-time earnings are 50 × $20 = $1,000, plus the $50 bonus, so the regular rate for that week is $1,050 ÷ 50 = $21.00. The overtime premium owed is 0.5 × $21.00 × 10 = $105, and the correct total is $1,155 — $5 more than simply adding the bonus to this calculator's answer. Five dollars is trivial on one week; on a crew of eight with a monthly bonus it is the kind of quiet underpayment that surfaces two years later as back wages.
One rate and one overtime figure is a single multiplication. A crew, a bonus scheme and a 52-week year is a payroll record: hours by person by week, the regular rate recomputed whenever extra pay lands, and a running total you can hand to an accountant. That is a spreadsheet job, and our small business bookkeeping template keeps wage costs beside the income they produced rather than in a separate app. To build the hours themselves first, the hours calculator converts clock times into decimal hours and the time card calculator totals a full week and splits out anything past 40.
$30 an hour (20 × 1.5). Ten overtime hours at that rate is $300.
Under US federal law (FLSA), yes — at least 1.5× for non-exempt employees working over 40 hours a week. Double time is not federally required; it comes from employer policy, contracts, or certain state rules.
