About Time Card Calculator
Hours worked equals clock-out minus clock-in, minus your unpaid break. Overnight shifts (where end is earlier than start) are handled by rolling over midnight. Gross pay multiplies decimal hours by your rate.
Formulas
Working minutes
Working minutes = (end − start + 1440) mod 1440 − break minutes
- 1440
- Minutes in a day — added then mod'd to handle overnight shifts
- t_end
- Clock-out time in minutes since midnight
- t_start
- Clock-in time in minutes since midnight
- b

Gross pay
Gross pay = (working minutes ÷ 60) × hourly rate
- t
- Working minutes after break deduction
- r
- Hourly pay rate

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How do overnight shifts work?
If your end time is earlier than your start time, the calculator assumes you clocked out the next day and adds 24 hours automatically.
Is this gross or net pay?
It's gross pay before taxes and deductions. Use the Salary calculator to estimate take-home pay.
