Work Hours Calculator

Add up worked hours for a whole week. Enter start and end times with breaks and get daily and weekly totals, plus pay if you add an hourly rate.

Fill in the days you worked and the week totals itself up. Add an hourly rate and you get the pay as well.

How Does It Work?

  1. Fill in your shiftsStart and end time for each day you worked. Leave a day blank if you did not work it.
  2. Add unpaid breaksBreak minutes are subtracted from that day only, so lunch does not get paid twice.
  3. Read the week totalHours and minutes, decimal hours for payroll, and pay if you enter a rate.

What Is It Used For?

Most timesheet mistakes come from adding minutes as if they were decimals — treating 8 h 45 m as 8.45 hours instead of 8.75. This calculator keeps the two formats separate and shows both, so what you invoice matches what you worked.

  • Filling in a weekly timesheet for an employer or an agency.
  • Invoicing a client for hours worked at an hourly rate.
  • Checking a payslip against the shifts you actually did.
  • Tracking hours on a side project or a second job.
  • Seeing whether a week went over a contracted number of hours.

Frequently Asked Questions

How do I add up hours worked in a week?

Convert each shift to minutes, subtract the break, add the days together and divide by 60 at the end. Adding hours and minutes separately is where most errors come from — this calculator does it in minutes throughout.

Why is 8 hours 45 minutes not 8.45 hours?

Minutes are sixtieths, not hundredths. 45 minutes is 45 ÷ 60 = 0.75, so the decimal figure is 8.75 hours. Using 8.45 would short you 18 minutes of pay.

Does it handle night shifts?

Yes. If the end time is earlier than the start time the shift is treated as running past midnight, so 22:00 to 06:30 counts as 8.5 hours before breaks.

Is overtime calculated?

Not automatically, because overtime thresholds and multipliers vary by contract and country. The total hours figure gives you the base to apply your own rule.

Is the pay figure exact?

It is hours × rate, before tax, deductions or premiums. Treat it as an estimate for checking a payslip rather than a payroll calculation.
