Payroll questions come in a chain: how many hours did I actually work, what is that in decimal, how much of it is overtime, what does the overtime tax break save me, and what lands in my account? Each calculator below handles one link in that chain and shows its working, so you can follow a week from timesheet to paycheck and spot where a number changed.
The tools are built around US conventions — decimal hours for payroll systems, time-and-a-half overtime, and the federal overtime deduction in force for 2025–2028 — and they are free for employees checking a stub, managers sanity-checking a rota, and small businesses without payroll software.
Which work or pay calculator do you need?
Start where your question starts. Totalling a shift or a week: the hours calculator for a single span, the time card calculator for a full timesheet with breaks, or the weekly hours calculator for a Monday-to-Sunday view. Payroll needs decimals — the hours to decimal calculator converts both ways. Overtime questions go to the overtime tax calculator for the current deduction and savings. For the final number, the paycheck calculator estimates take-home pay, and the PTO calculator tracks accrued time off.
