About this calculator
A time card is a list of clock-in and clock-out times. For each day the calculator turns both times into minutes since midnight, takes the difference (adding 24 hours when the shift ends after midnight), subtracts the unpaid break and adds the result to the weekly total. Days with both boxes blank are days off.
Total hours are shown two ways. Hours:minutes is what a punch clock prints (42:30). Decimal hours are what payroll multiplies by the hourly rate (42.50): minutes ÷ 60, so 30 minutes is 0.50 and 15 minutes is 0.25. The minutes to decimal hours converter at /en/calculators/time-zones/minutes-to-decimal-hours/ has the full 1 to 60 minute table.
Overtime. Under the US Fair Labor Standards Act a non-exempt employee earns at least 1.5 times the regular rate for every hour over 40 in a workweek, a fixed and recurring period of 168 hours. Each week stands alone, so a bi-weekly pay period is two separate 40-hour tests, never an 80-hour one; the bi-weekly option here applies the weekly split to two weeks like the one entered. Ontario's Employment Standards Act sets the weekly limit at 44 hours; pick "no overtime" for a salaried or exempt employee. Daily overtime rules (California pays 1.5× after 8 hours in a day and 2× after 12) are not applied: split those hours out by hand.
Gross pay = regular hours × rate + overtime hours × rate × overtime multiplier, times the number of weeks in the pay period. It is pay before tax and deductions; the net pay calculator at /en/calculators/payroll/net-pay-calculator/ estimates the net amount.
Times can be typed as 8:00 AM, 5:30 PM, 17:30 or 1730. Rounding to the nearest quarter hour is allowed under 29 CFR 785.48 as long as it does not consistently favour the employer; this calculator does not round, so compare its total with the rounded one on your pay stub.

How to use
Enter the in and out time for each day worked, the unpaid break taken each of those days, your hourly rate and the overtime rule that applies, then pick weekly or bi-weekly. Example (the defaults): Monday to Friday 8:00 AM to 5:00 PM with a 30-minute unpaid lunch. Each day is 9 hours minus 0:30 = 8:30, so the week is 5 × 8.5 = 42.5 hours (42:30). With overtime after 40 hours that is 40 regular hours and 2.5 overtime hours. At $20 an hour, regular pay is 40 × $20 = $800 and overtime pay is 2.5 × $20 × 1.5 = $75, so gross pay for the week is $875. Choosing bi-weekly doubles it to $1,750. Example: an overnight shift. Clock in at 10:00 PM, out at 6:00 AM, no break: the calculator adds a day to the out time, so the shift is 8 hours, not −16.
Frequently asked questions
How do I convert minutes to decimal hours on a time card?
Divide the minutes by 60. 15 minutes = 0.25, 20 minutes = 0.33, 30 minutes = 0.50, 45 minutes = 0.75, 50 minutes = 0.83. So 42 hours 30 minutes is 42.5 hours, and at $20 an hour that is 42.5 × $20 before any overtime premium.
Does a bi-weekly pay period mean overtime starts after 80 hours?
No. The FLSA counts each workweek on its own, so 45 hours one week and 35 the next is 5 overtime hours even though the two weeks add up to 80. This calculator's bi-weekly option therefore applies the weekly overtime split to each of two identical weeks; if the two weeks differ, run them separately and add the results.
Are breaks paid?
Under federal law short rest breaks of about 5 to 20 minutes count as hours worked and are paid; bona fide meal periods of 30 minutes or more during which the employee is completely relieved of duty are not (29 CFR 785.18 and 785.19). Enter only the unpaid meal break here.
Can my employer round my time card to the nearest quarter hour?
Yes, 29 CFR 785.48 allows rounding to the nearest 5 minutes, tenth of an hour or quarter hour, provided the practice averages out and does not consistently fail to pay for all time worked. Under quarter-hour rounding, 8:07 becomes 8:00 and 8:08 becomes 8:15 (the "7-minute rule").
What about overtime after 8 hours in a day?
Federal law has no daily overtime, only the 40-hour weekly test. California requires 1.5× after 8 hours in a day and 2× after 12, Alaska, Nevada and Colorado have daily rules too, and some union contracts add their own. This calculator applies a weekly limit only, so for daily overtime work out the premium hours by hand.
Is the result my take-home pay?
No, it is gross pay before federal and state income tax, Social Security and Medicare and any deductions. Net pay is typically 70 to 80% of gross; the net pay calculator estimates it from your filing details.
