Time Card Calculator

Add up shift hours with unpaid breaks, overtime, and gross pay.

Enter your shifts as start time, end time and unpaid break, one per line, and this adds up the hours. It handles 12-hour and 24-hour times and shifts that run past midnight, and with an hourly rate it shows gross pay, applying an overtime multiplier after the threshold you set.

How to use it

  1. Enter one shift per line: start, end and break minutes.
  2. Optionally enter an hourly rate.
  3. Set when overtime starts and its multiplier.
  4. Read the total hours and pay.

When it helps

  • Tracking weekly hours.
  • Filling in a timesheet.
  • Estimating pay before payday.
  • Double-checking an employer's calculation.

Good to know

  • If a shift ends earlier than it starts, it's treated as running overnight.
  • Enter breaks in minutes, so a half-hour lunch is 30.
  • Overtime rules vary by country and contract, so check yours.

How hours are worked out

For each shift, the tool takes the end time minus the start time, adds 24 hours if the end is earlier, which handles night shifts, and subtracts the break. Times can be written in 24-hour form or with am and pm. Totals are then added across all lines.

Overtime is any time beyond the threshold you set, paid at your multiplier. The regular and overtime hours are shown separately so you can check each against your contract.

Worked example: a week of shifts

Five shifts: 09:00 to 17:30 with 30 minutes' break, 08:45 to 17:00 with 45, 09:00 to 13:00, 10:00 to 18:00 with 30, and 09:15 to 17:15 with 30. The totals come to 37.0 hours or so, under the 40-hour overtime threshold, so pay is hours times rate.

If you add a Saturday shift of 6 hours, the total goes over 40 and the extra hours are paid at 1.5 times the rate.

Keeping accurate records

Write your times down the day you work them, not at the end of the week. Keep a copy of your schedule in case of disputes. Rounding rules differ between employers, so ask whether yours rounds to the nearest 5 or 15 minutes.

If your pay doesn't match your own record, show the calculation to your employer politely. Most differences come from breaks or rounding.

Employer and employee tips

Employees should check each pay slip against their own records. Employers should state clearly how breaks, rounding and overtime are treated. Many disputes come from misunderstanding rather than bad faith.

If your hours vary a lot, keep a simple weekly summary with start, finish and break for each day. It takes a minute and saves arguments later.

A note on rounding

Some employers round clock-in times to the nearest quarter hour. This tool uses the exact minutes you enter, so if your payroll rounds, enter the rounded times to match.
