Which calculator do I need?
- Totalling a timecard. Use the work hours calculator for a weekly or 14-day biweekly card with lunch breaks. Need the time to leave? Try the clock out calculator. Converting 7h 45m for payroll? Use the decimal hours calculator.
- Checking a paycheck. The overtime pay calculator splits straight time from the time-and-a-half premium; the salary to hourly calculator turns an annual figure into an hourly rate.
- Planning time off. Estimate a balance with the PTO accrual calculator, then find when you'll have enough with PTO goal date.
- Scheduling a team. Lay out rotations with the rotating shift calendar, then size staffing with the FTE calculator and shift coverage calculator.
Every calculator runs in your browser; nothing you enter is sent anywhere. Results are estimates — read how they're calculated, the worked-example guides, or the reference data.
