Work Hours & Time Card Calculator

How it works

1. Use Quick Hours for one shift, or Weekly Time Card for Monday–Sunday.
2. Enter clock-in, clock-out and total unpaid break minutes. Add shifts for split days or copy a schedule to selected days.
3. Review hours, optional overtime settings and hourly rate. Rounding is off unless you enable it in Advanced settings.
4. Correct incomplete entries, then copy a summary, download CSV or print / save PDF.

A real example

Work hours, breaks and decimal hours

Subtract clock-in from clock-out, then subtract the total unpaid break duration. Paid breaks should not be subtracted. Add separate shifts for split days rather than counting the gap between them as work.

Decimal hours are minutes divided by 60: 7h 30m is 7.5 hours, not 7.30. Displayed decimals use up to four places; calculations retain whole minutes before pay calculation. Gross pay is displayed to two decimal places, without a currency conversion.

Overnight shifts and weekly overtime

If clock-out is earlier than clock-in, the shift ends the next day. 22:00–06:00 is eight hours before breaks. Equal clock-in and clock-out is zero hours, never 24. Shifts are attributed entirely to the day on which they are entered, including overnight time.

Weekly overtime is max(0, total hours − your threshold); regular hours are the remainder. The default threshold is 40 hours and can be changed or disabled. Quick Hours does not calculate weekly overtime. These are configurable arithmetic rules, not a determination of legal entitlement.

The calculator uses entered clock times, not timezone-aware timestamps. It does not adjust for daylight saving, detect overlapping entries, split overnight hours across weeks, or handle shifts of 24 hours or longer. Check those cases independently.

Time rounding and estimated pay

Exact entered minutes are used by default. Optional nearest 5-, 10- or 15-minute rounding applies separately to each shift’s worked duration after breaks; halfway values round up. For example, 8h 7m rounds to 8h with a 15-minute interval, while 8h 8m rounds to 8h 15m. Rounding never alters the displayed clock times.

An optional hourly rate estimates regular pay plus overtime pay at your chosen multiplier (default 1.5×). Use one currency throughout. This does not calculate taxes, deductions, benefits or net pay. Overtime and rounding rules vary by employer and jurisdiction; this is not payroll or legal advice.

Avoid common time-card mistakes

• Check AM/PM in your browser’s time picker. The browser may display 12-hour or 24-hour entry.
• Enter breaks as total whole minutes, including multiple unpaid breaks. A break longer than the shift is an error.
• Leave both time fields blank for a day off. A single entered time is incomplete and blocks final exports.
• Use the Monday week-start date; choosing another day moves it back to that week’s Monday. Verify overnight entries belong in the intended week.
• Copying a schedule replaces selected days. Check copied shifts and avoid duplicate or overlapping entries.
