Hours Worked Calculator

Enter each day's start and end time and unpaid break to total the week, split regular from overtime hours, and see gross pay at your rate.

Weekly time card calculator

Use your employer’s fixed seven-day workweek; Day 1 need not be Monday. Enter one shift per row. Clear both times to skip a day. Enter 0 for no unpaid break, or a $0 rate to calculate hours only.

How hours and overtime are calculated

daily hours   = (end − start − unpaid break) ÷ 60   (end before start = overnight shift)
total hours   = sum of daily hours
overtime      = max(0, total − 40);  regular = total − overtime
gross pay     = regular × rate + overtime × rate × 1.5

Minutes are summed before converting to decimal hours, so pay uses unrounded hours. The hourly rate is assumed to be the applicable regular rate; bonuses, multiple pay rates and shift differentials are not calculated. Daily overtime, double-time, special industry rules and taxes are excluded.

A workweek is a fixed, recurring 168-hour period. Include only work belonging to that period; do not average hours across weeks. Each row supports a shift shorter than 24 hours, and break minutes cannot exceed that shift. Start and end times are both needed for an active row.

Frequently asked questions

How do I calculate hours worked from a time card?

Subtract the start time from the end time for each day, subtract unpaid breaks, and add the days together. 9:00 to 17:00 with a 30-minute lunch is 7.5 hours; five such days are 37.5 hours.

When does overtime start?

For employees covered by federal FLSA overtime rules and not exempt, hours over 40 in one workweek generally require at least 1.5 times the regular rate. State rules and agreements can require additional overtime. This tool models the federal weekly threshold only.

Are breaks paid?

Short rest breaks, usually 5 to 20 minutes, generally count as paid work under federal rules. A bona fide meal period is generally unpaid only when the worker is completely relieved of duties; length alone does not decide it. Enter only breaks that are properly unpaid.

How do I convert minutes to decimal hours?

Divide minutes by 60: 45 minutes is 0.75 hours, 20 minutes is 0.33. Payroll systems use decimal hours, which is why the calculator shows both formats.

Does this handle overnight shifts?

An end time earlier than the start means the following day: 22:00 to 06:00 is eight hours before breaks. Matching times mean zero hours, not 24. The tool does not use dates, detect overlapping shifts or adjust for daylight saving changes. Split work at the boundary of your workweek.
