Time Card Calculator
A time card calculator adds up the hours between your clock-in and clock-out times each day, subtracts unpaid breaks, and gives you daily and weekly totals in both hours:minutes and decimal hours.
Add up a week of punches in seconds. Enter each day's start and end time, subtract unpaid breaks, and this time card calculator shows your daily and weekly totals in both hh:mm and decimal hours.
It handles overnight shifts, configurable overtime, optional pay rates, and rounding rules — and it works entirely in your browser, so nothing you type is uploaded.

How to use this calculator
- Pick your time format (12-hour AM/PM or 24-hour).
- For each day you worked, type a start time and an end time.
- Enter unpaid break minutes (for example, 30 for a half-hour lunch).
- If a shift ran past midnight, switch on the overnight toggle for that row.
- Set your overtime rule and, optionally, an hourly rate to see gross pay.
- Read your totals, then print or export a clean report.
How overtime is handled
On a time card, overtime is usually any time past 40 hours in a week. Choose Weekly to flag it automatically, or Daily + weekly if your job also counts hours past 8 in a single day.
How breaks are handled
Enter the unpaid minutes for each shift — a 30-minute lunch, say — and the calculator removes them from that day's total. Paid breaks stay in; just leave the field at 0.
Examples
A standard day with lunch
9:00 AM to 5:30 PM with a 30-minute unpaid lunch is 8 hours worked (8:30 of clock time minus 0:30 break).
A full week
Five 8-hour days totals 40:00, or 40.00 decimal hours. Add a sixth 6-hour day and weekly overtime (over 40) kicks in for 6:00 of OT.
Tips
- hh:mm is best for reading a schedule; decimal hours are what most payroll systems want.
- 15 minutes = 0.25, 30 = 0.50, 45 = 0.75 — memorize these four and most conversions are instant.
Need to turn minutes into decimals (15 = 0.25, 30 = 0.50, 45 = 0.75)? Use the minutes-to-decimal guide or the decimal hours calculator.
Printing & exporting your timesheet
Use Print / save as PDF for a clean report — ads, navigation, and controls are removed automatically by the print styles, leaving just your hours and totals. Use Export CSV to download a spreadsheet you can import into payroll or open in Excel or Google Sheets.
Frequently asked questions
Is this time card calculator free?
Yes. It is free, needs no account, and runs in your browser. Saved timesheets are stored only on your device.
How do I handle an unpaid lunch?
Type the break length in minutes in the break field for that day. The calculator subtracts it from the clock time so your worked total is accurate.
Can it total an overnight shift?
Yes. If your end time is earlier than your start time, it assumes the shift crossed midnight. You can also flip the overnight toggle on a row to be explicit.
Does it round my punches?
Only if you choose a rounding rule. By default it uses exact minutes. You can switch to 5-, 6-, or 15-minute rounding to match your employer.
