Time Card Calculator

1. For each day, enter the clock-in and clock-out time for every shift.
2. Enter the number of unpaid break minutes for each shift. Leave it blank if there was no unpaid break.
3. Add shifts or copy a day’s schedule when needed. Fix any errors shown beside a shift.
4. Open pay and advanced settings to add an hourly rate, choose overtime rules, or apply time rounding.
5. Read the weekly total and daily breakdown. Change the result format between hours and minutes and decimal hours.

Worked Time = Clock-Out Time − Clock-In Time − Unpaid Breaks. Each shift is calculated separately. Scheduled time includes the full clock-in to clock-out span; worked time subtracts the shift’s unpaid break once. Paid breaks remain part of paid time.

For example, 9:00 AM to 5:30 PM is 8 hours 30 minutes scheduled. Subtract a 30-minute unpaid break to get 8 hours worked.

Decimal hours are not written like hours and minutes. Convert minutes by dividing by 60. For example, 30 minutes ÷ 60 = 0.50 hours, so 8 hours 30 minutes equals 8.50 decimal hours. It does not equal 8.30 hours; 0.30 of an hour is 18 minutes.

If clock-out is earlier than clock-in, the calculator treats clock-out as the following day. A shift from 10:00 PM to 6:00 AM spans eight scheduled hours. Any unpaid break is then subtracted from those hours.

Each shift is limited to 24 hours. Overnight shifts are checked for overlaps with other shifts, including a shift entered on the following day.

Overtime thresholds and pay multipliers depend on the rules that apply to a worker. Weekly overtime is based on a user-configured weekly threshold. Daily overtime is optional and disabled by default. Optional double time is configured under advanced settings.

When more than one rule is enabled, the calculator classifies daily double time and daily overtime first. It then applies the weekly threshold only to remaining regular minutes. Each minute is assigned to one category so daily and weekly overtime do not double-count it.

Overtime rules vary by country, state, industry, contract, and employee classification. Configure the calculator according to the rules that apply to you.

Some employers round time entries to set increments. This calculator can round clock-in and clock-out times independently, or round the final shift duration after elapsed time is calculated. It never combines these methods. The entered times remain visible so you can compare them with the rounded times used.

Workplace rounding policies and legal requirements differ. Choose no rounding unless you know which policy applies.

When an hourly rate is entered, regular, overtime, and optional double-time pay are estimated using the selected multipliers. Currency selection changes the displayed currency format only; no exchange rate is applied.

Estimated gross pay is before taxes, benefits, deductions, bonuses, commissions, and other payroll adjustments. The result is an estimate and is not an official payroll record.
