Time Card Calculator: Track Work Hours & Overtime

How to use this tool

1. Enter shifts. Fill in clock-in, clock-out, and unpaid break minutes for each day.
2. Choose an overtime method. Select daily or weekly overtime and set the threshold you want to use.
3. Review hours and pay. Optionally enter an hourly rate and overtime multiplier to estimate gross pay.
4. Export your time card. Copy the summary, download a CSV, or print the current entries.

How to use the time card calculator

Enter a clock-in time, clock-out time, and unpaid break in minutes for each day. The calculator subtracts the break from the elapsed shift and totals the hours for all valid rows. If a shift ends after midnight, enter the earlier clock-out time as usual; the calculator treats it as the following day. Add weekend or custom rows with + Add day, remove rows you do not need, or use Reset to defaults to restore Monday through Friday.

Results show each shift as hours and minutes, with decimal hours for systems that ask for values such as 7.50. The calculator uses exact entered times without rounding. If break minutes exceed the elapsed shift, the worked-time result is zero rather than a negative shift or an accidental overnight total.

Choose how overtime is summarized

Daily overtime compares each shift with the daily threshold, which starts at 8 hours. Hours above that threshold are shown on their row and added to the overtime summary. Weekly overtime adds all valid shifts first, then compares the total with the weekly threshold, which starts at 40 hours. In weekly mode, the overtime amount appears in the summary only because the calculator does not assign weekly excess hours to a particular day. You can change the threshold values and switch modes to compare results.

The selected mode is a calculation method, not a determination of employment law. This tool does not combine daily and weekly rules, account for special state or industry requirements, identify a legally defined workweek, or resolve exceptions such as double time. For a payroll submission, confirm which rules apply to your job and use your employer's official timekeeping process.

Estimate gross pay

Enter an hourly rate to see estimated regular pay, overtime pay, and gross pay before taxes and deductions. The calculator uses regular hours × rate for regular pay and overtime hours × rate × multiplier for overtime pay. The default overtime multiplier is 1.5, and you can change it to match the assumption you want to test.

For example, in weekly mode with a 40-hour threshold, a 45-hour week at $20 per hour splits into 40 regular hours and 5 overtime hours. At a 1.5 multiplier, that is $800 regular pay plus $150 overtime pay, for an estimated $950 gross. This estimate does not include tax withholding, paid breaks, premiums, benefits, or other payroll adjustments.

Copy, download, or print

Use Copy summary to paste the totals and selected overtime threshold into a message or note. Download CSV creates a spreadsheet-friendly file with the entered rows, hour totals, overtime method, and optional gross-pay estimate. Both actions run in this browser; the calculator does not save your time card or send its values to a server. The print action formats the current calculator for a paper or PDF printout.
