Add up clock-in and clock-out times for the week, subtract breaks, and get total hours, overtime and gross pay — instantly, as you type.
Times crossing midnight (clock-out earlier than clock-in) are treated as an overnight shift.
A paper time sheet looks simple until you actually have to add it up. This time card calculator turns a week of clock-in and clock-out times into the numbers that matter: total hours worked, how many of those count as overtime, and — if you add an hourly rate — your gross pay before tax. Type the times for each day, set the break length, and the result updates instantly. No converting minutes into decimals by hand, no second-guessing an overnight shift, no maths errors that quietly shave money off a paycheck.
It is built for the way real timesheets work. Each day has its own clock-in, clock-out and unpaid break, so part-days, split shifts across the week and days off are all handled cleanly. Leave a day blank and it simply counts as zero. Because everything runs in your browser, nothing you type is sent anywhere — it is just as private and fast on a phone at the end of a shift as it is on a desktop in the payroll office.
The one part people get wrong by hand is the conversion from clock time to decimal hours. Forty-five minutes is not 0.45 of an hour — it is 0.75. The calculator converts every minute correctly (minute ÷ 60), which is why a shift of 8 hours and 30 minutes shows as 8.50 rather than 8.30. When a clock-out time is earlier than the clock-in, the shift is assumed to cross midnight and 24 hours are added, so a 22:00–06:00 night shift correctly reads as 8 hours.
Payroll systems pay in decimal hours, not hours-and-minutes, so it helps to know the common conversions at a glance.
| Minutes | Decimal hour | Minutes | Decimal hour |
|---|---|---|---|
| 5 min | 0.08 | 35 min | 0.58 |
| 10 min | 0.17 | 40 min | 0.67 |
| 15 min | 0.25 | 45 min | 0.75 |
| 20 min | 0.33 | 50 min | 0.83 |
| 30 min | 0.50 | 60 min | 1.00 |
To convert any minutes to a decimal, divide by 60. To go the other way, multiply the decimal part by 60.
In the United States, the federal Fair Labor Standards Act (FLSA) requires non-exempt employees to be paid 1.5× their regular rate for hours worked beyond 40 in a workweek — which is the default this calculator uses. Note that the threshold is weekly, not daily: working 12 hours one day and 4 the next is still under 40 for the week and triggers no federal overtime. Some states layer on daily overtime rules, however. California, for example, requires 1.5× after 8 hours in a single day and 2× after 12, regardless of the weekly total. Always check your state and your employment contract, because the higher of the applicable rules generally applies. This tool models the common weekly-threshold case at 1.5×; adjust the threshold to match your agreement.
Decide whether breaks are paid or unpaid before you start. Short rest breaks (typically under 20 minutes) are often paid and should be entered as 0; longer meal breaks are usually unpaid. Round consistently. Many employers round clock times to the nearest quarter-hour; if yours does, round each in/out time before entering it so your figure matches the payslip. Don't mix daily and weekly overtime. If your state uses daily overtime, calculate it separately. Keep your own record. A personal copy of your hours is the simplest way to spot a payroll error early, and this calculator gives you a quick weekly total to compare against the official one.
Employers are allowed to round recorded time, but the rounding has to be neutral — it can't systematically favour the employer. The common, legally accepted method is rounding to the nearest quarter-hour using the "7-minute rule": times 1–7 minutes past a quarter round down, and 8–14 minutes round up. Over many shifts this should even out to roughly zero. If you consistently see your hours rounded down, that is worth raising. Keeping your own simple time card — even a note on your phone with clock-in and clock-out times — protects you, because under the FLSA the burden is on the employer to keep accurate records, and your contemporaneous notes carry real weight if there is ever a dispute. This calculator is designed to make that personal record effortless: enter the times once and the weekly total, overtime split and pay are all there.
Divide the minutes by 60. For example, 30 minutes is 30 ÷ 60 = 0.50 hours, and 45 minutes is 0.75 hours. This calculator does the conversion automatically for every shift.
By default, any hours worked beyond 40 in the week are paid at 1.5× the regular rate. You can change the threshold to match your contract or state rules. Some states also apply daily overtime, which this tool does not model automatically.
Yes. If the clock-out time is earlier than the clock-in time, the shift is treated as crossing midnight and 24 hours are added, so a 22:00–06:00 shift correctly reads as 8 hours.
If your break is unpaid, enter it in the break field so it is deducted. If short breaks are paid under your employer's policy, leave the break at 0 for those days.
No. Gross pay is before any deductions such as income tax, Social Security or pension contributions. Your take-home pay will be lower. Use a paycheck or salary calculator to estimate net pay.
No. All calculations run locally in your browser. Nothing you type is uploaded or stored, so your hours and pay stay private.
