How this time card calculator works
The calculator subtracts each start time from the end time, deducts the break in minutes, then adds the net time across all rows.
net shift minutes = end time - start time - break minutes
weekly hours = total net minutes ÷ 60
estimated pay = hours × hourly rateIf the end time is earlier than the start time, the calculator treats the shift as passing midnight. For example, 22:00 to 06:00 is treated as an overnight 8-hour shift before breaks.
Why decimal hours matter
Payroll and invoices often use decimal hours instead of hours and minutes. For example, 7 hours 30 minutes is 7.5 hours, and 7 hours 15 minutes is 7.25 hours.
For pay estimates, the calculator uses the decimal total because hourly pay is usually calculated as a rate multiplied by decimal hours.
Overtime and pay estimates
You can enter an hourly rate and an overtime threshold to get a simple estimate. This is useful for planning, but it is not a substitute for your employer's payroll rules.
Some jobs use different overtime rules for evenings, weekends, bank holidays or contractual hours. Check your contract or payslip for the official calculation.
Use the salary-to-hourly calculator to convert annual salary into an estimated hourly rate.
Time card calculator FAQs
Can this calculator handle unpaid breaks?
Yes. Enter the break length in minutes for each day, and the calculator deducts it from the daily total.
Can it handle overnight shifts?
Yes. If the end time is earlier than the start time, the calculator treats the shift as passing midnight.
Is the pay estimate official?
No. It is a simple estimate. Your official pay may depend on your contract, payroll rules, overtime policy, tax, pension deductions and other adjustments.
