Time Card Calculator

Enter a start time, finish time and unpaid break for each day to get the week's total in hours and minutes and in decimal hours for payroll. Add an hourly rate to see regular pay, overtime above 40 hours (or your own threshold) and the total. Night shifts that finish after midnight are handled. Nothing is uploaded.

How to use the Time Card Calculator

  1. 1Enter the start and finish time for each day you worked, and the unpaid break in minutes.
  2. 2Leave days you did not work blank.
  3. 3Enter your hourly rate, the weekly hours after which overtime starts, and the overtime rate.
  4. 4Read the total hours, the decimal hours and the gross pay.

How it works

Each day's hours are the finish time minus the start time, minus the break. A finish earlier than the start is treated as the next day, so 22:00 to 06:00 is 8 hours.

Times are added in whole minutes and only then shown as hours and minutes (7:45) and as decimal hours (7.75). Decimal hours are what most payroll systems want: 45 minutes is 0.75 of an hour, not 0.45.

Overtime here is weekly: hours above the threshold — 40 by default, as under the US federal rule for many employees — are paid at the overtime rate, such as 1.5 for time and a half. Some places and contracts use daily overtime, double time or different thresholds, so set the numbers your employer uses.

Pay is gross, before tax and other deductions. Rounding rules for clocking in and out (such as to the nearest quarter hour) vary by employer and are not applied.

The formula

hours = finish − start − break pay = regular hours × rate + overtime hours × rate × multiplier
regular hours
up to the weekly overtime threshold
overtime hours
anything above the threshold
multiplier
1.5 for time and a half, 2 for double time

Worked example

45 hours in a week at 20.00 an hour, time and a half after 40 hours

  1. Regular: 40 h × 20.00 = 800.00
  2. Overtime: 5 h × 20.00 × 1.5 = 150.00
  3. Total: 800.00 + 150.00

Result: 950.00 gross for the week.

Tips and common mistakes

  • Record times as you go rather than reconstructing the week on Friday.
  • Use decimal hours on timesheets that ask for “hours” as a number.
  • Check whether your employer rounds clock-in times before comparing with your payslip.
  • Keep your own copy of hours worked in case of a pay dispute.

Frequently asked questions

How do I convert minutes to decimal hours?
Divide the minutes by 60: 15 minutes is 0.25, 30 is 0.5 and 45 is 0.75. So 7 hours 45 minutes is 7.75 hours.
Does it handle overnight shifts?
Yes. If the finish time is earlier than the start, the shift is taken to end the next day.
Should breaks be included?
Enter unpaid breaks in the break column and they are subtracted. Paid breaks count as working time, so leave them out.
When does overtime start?
That depends on your country, state and contract. 40 hours a week is common in the US; set 0 if you have no overtime, or your own threshold.
Are my hours saved or sent anywhere?
No. Everything is calculated in your browser and nothing is stored, so note the totals before closing the page.
Can I calculate double time?
Set the overtime rate to 2. For time and a half, use 1.5.
