Work Hours Calculator

Calculate total work hours and minutes from start and end times including breaks. Free timesheet calculator.

Calculate total hours worked from clock-in and clock-out times, with optional break deduction. Useful for timesheet tracking, freelance billing, and overtime calculations.

How to use it

Enter your start and end times for each day, along with any break duration to subtract. The calculator gives daily hours and the weekly total. You can use it for a single shift or build up a full week's timesheet.

Overtime rules (US)

In the US, non-exempt employees are entitled to 1.5× their regular rate for hours over 40 in a workweek (federal FLSA). Some states like California also require daily overtime (over 8 hours/day). Check your state's specific rules.

Freelance billing

Track billable hours per client by logging each session. Multiply total hours by your hourly rate to get the invoice amount. Many freelancers round to the nearest 15 minutes — enter your rounded times for accurate billing.
