Work Hours Calculator

Our Working Hours Calculator is a simple and accurate tool for calculating weekly work hours, overtime hours, break-adjusted time, and total pay. Whether you are an employee, freelancer, contractor, manager, or small business owner, this calculator helps you track work time across the full week and understand exactly how many regular hours and overtime hours you worked.

This weekly work hours calculator supports start time, end time, and break duration for each day of the week. It automatically subtracts unpaid breaks, calculates total hours worked, converts hours into decimal hours, and shows a complete weekly summary. If your shift crosses midnight, the calculator can handle overnight shifts correctly, making it useful for night shifts, rotating schedules, hospitality jobs, healthcare workers, warehouse employees, security staff, and other roles with non-standard hours.

One of the biggest strengths of this overtime calculator is its ability to separate regular hours from overtime hours. It can calculate daily overtime, weekly overtime, and total overtime without double-counting the same hours. In this version, hours above 8 in a day are treated as daily overtime, and remaining regular hours above 40 in a week are treated as weekly overtime. This makes it especially useful for people who want a more realistic payroll estimate instead of a basic hours worked calculator.

If you enter your hourly rate, the calculator also works as a pay calculator. It shows regular pay, overtime pay, and total pay using a 1.5x overtime multiplier. This is helpful for estimating weekly earnings, checking timesheets, comparing schedules, planning shifts, and reviewing paycheck accuracy before payroll is processed.
