Work Hours Calculator

The Work Hours Calculator totals the time worked across a shift or pay period, subtracting unpaid breaks and, where applicable, separating regular hours from overtime. You enter start and end times (and any break duration), and it returns the net hours worked, making it useful for timesheets, freelance billing, and reconciling logged hours against what should be paid.

Mechanically it converts your clock-in and clock-out times into minutes, handles shifts that cross midnight, subtracts break time, and divides the remainder back into hours and minutes. When an overtime threshold is set — commonly 40 hours per week or 8 hours per day depending on jurisdiction — it splits the total into standard pay and overtime pay segments so you can apply the correct rate to each.

This is handy for hourly employees verifying a paycheck, managers building schedules, and contractors invoicing clients by the hour. It removes the error-prone mental math of converting between minutes and decimal hours — for example knowing that a 7-hour-45-minute shift is 7.75 hours for billing, not 7.45 — and makes overtime visible before payroll surprises arise.

Practical tips: confirm whether your breaks are paid or unpaid before subtracting them, and check your local rules for whether overtime is daily, weekly, or both. To extend the calculation, use a Time Duration Calculator for one-off intervals or pair the decimal-hour output with an hourly rate to estimate gross pay.
