Time Card Calculator.
Five shifts of 9:00 to 17:30 with a 30-minute unpaid break add up to 40 hours, all regular time; a sixth shift of 5 hours makes 45, with 5 hours of overtime. Enter each day’s start, finish and break, and this calculator totals the week in hours and minutes and works out regular pay, overtime and gross pay.
A finish time earlier than the start time is treated as an overnight shift ending the next day. Overtime rules and multipliers depend on your country, state and contract; set them to match. Nothing is sent to a server.

What you'll get.
A real example of what this tool produces. Run it above with your own inputs.
A time card, or timesheet, records when someone started and finished work each day and how long they took off for breaks. Adding it up by hand means converting clock times to hours, subtracting breaks, handling shifts that cross midnight and then splitting overtime from regular time. This calculator does all of it for a full week, in hours and minutes and in decimal hours for payroll.
Choose the overtime rule that applies to you: over a weekly limit (the US federal rule under the Fair Labor Standards Act is generally overtime after 40 hours in a workweek for non-exempt employees), over a daily limit, or a daily limit followed by a weekly limit, which matches how some states and contracts work. Set the multiplier, usually 1.5, and an hourly rate to see gross pay.
The tool is free and runs in your browser. It comes from Neweb, the AI website builder for small businesses (free plan, paid plans from $9/month billed yearly, $19 month-to-month). It is a calculator, not legal or payroll advice; overtime law differs by country, state and contract.
How to use the time card calculator
Enter the start and end time for each day worked, and the unpaid break in minutes. Monday to Friday are pre-filled as an example; change or clear them.
Leave days off blank. A finish time earlier than the start counts as an overnight shift.
Choose the overtime rule and set the weekly limit, daily limit and multiplier that apply to you.
Optionally add the hourly rate and currency to see regular, overtime and gross pay.
Click Calculate hours. Each day shows its hours, and the panel shows the week in hours and minutes and in decimals.
Why this matters for your business
Payroll runs on decimal hours, people think in clock time. 7 hours 45 minutes is 7.75 hours, not 7.45. That single slip is one of the most common payroll errors in small businesses.
Overtime mistakes are expensive. Underpaying overtime can lead to back pay claims and penalties in many countries; overpaying adds up quietly. Getting the split right every week protects both sides.
Accurate records are often a legal duty. Many employment laws require employers to keep records of hours worked for hourly staff. A consistent weekly calculation makes those records easy to produce.
Tips for better results
- Convert minutes to decimals by dividing by 60: 15 minutes is 0.25, 30 is 0.5, 45 is 0.75.
- Only subtract breaks that are unpaid. Short rest breaks are paid time in many jurisdictions.
- In the US, check your state as well as federal rules; some states require daily overtime or double time.
- In the UK and EU there is usually no statutory overtime premium; the rate comes from the contract, while working-time rules cap average weekly hours.
- Freelancers can use the same tool to total billable hours, then price them with the hourly rate calculator.
- Record pay on a payslip with the salary slip generator.
Example
A real-world walkthrough
A café in Portland employs a barista at $18.50 an hour. Her week: Monday to Friday 9:00 to 17:30 with a 30-minute unpaid lunch, plus Saturday 8:00 to 13:00 with no break. The calculator shows 8:00 hours each weekday and 5:00 on Saturday, 45:00 hours in total.
With the weekly rule at 40 hours and a 1.5 multiplier, that is 40 regular hours ($740.00) and 5 overtime hours at $27.75 ($138.75), for gross pay of $878.75 before deductions. The owner copies the decimal figures into payroll.
Frequently asked questions
How do I calculate hours worked from start and end times?
Subtract the start time from the end time, then subtract any unpaid break. For 9:00 to 17:30 with a 30-minute lunch: 8 hours 30 minutes minus 30 minutes is 8 hours. If the end time is earlier than the start, the shift crossed midnight, so add 24 hours to the end time first: 22:00 to 06:30 is 8 hours 30 minutes. The calculator handles both cases for each day of the week.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60 and add them to the whole hours. 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours; 8 hours 20 minutes is 8.33 hours. Payroll systems and hourly pay calculations use the decimal figure. The calculator shows every result both ways, as hours:minutes and in decimals.
When does overtime start?
It depends on where you work. Under the US federal Fair Labor Standards Act, non-exempt employees generally earn at least 1.5 times their regular rate for hours over 40 in a workweek, and some states add daily overtime. Many other countries leave the overtime premium to contracts or collective agreements while limiting total working hours. Check your national or state labour department, then set the calculator's rule, limits and multiplier to match.
Should breaks be deducted from hours worked?
Only unpaid breaks. A meal break where the employee is fully relieved of duty is commonly unpaid; short rest breaks are often paid and should not be deducted. Rules on required breaks and whether they are paid vary by country and state. Enter only the unpaid minutes in the break column.
Can I use this for more than one employee?
Yes, one week at a time. Enter one employee's times, note the totals, then click Clear week and enter the next. The tool does not store anything, so keep your own record or print the results. For larger teams, a time-tracking or payroll system that records clock-ins automatically will save time.
