How to choose the right calculator

If you are checking a paycheck, start with the calculator that matches the input you have. Have clock-in and clock-out times? Use the Payroll Hours Calculator or Time Card Calculator. Have an hourly rate and a guess of weekly hours? Use the Hourly Pay Calculator. Already have decimal hours from a timesheet export? Skip to the Gross Pay Calculator.

If you suspect a problem with how time is being recorded — punches always rounding down, lunch always deducted as 30 minutes — start with the rounding hub and the lunch break guide. Those two issues account for most timesheet disputes.

Frequently Asked Questions

If you are converting clock-in and clock-out times to a paycheck, start with the Payroll Hours Calculator or Time Card Calculator. If you only need to convert minutes into decimal hours for an existing timesheet, use the Minutes to Decimal Calculator.

Before you use the result

Our calculators give quick payroll-time and pay estimates. Your final paycheck depends on factors this tool does not see, including employer policy, state and local rules, time clock rounding, paid versus unpaid breaks, premium pay, deductions, and how your payroll provider applies them.

  • Confirm pay rules with your employer, payroll provider, or HR team.
  • Overtime, breaks, and rounding rules can change by state.
