What is the Hours Calculator?

The Hours Calculator totals your work hours for a full week from daily clock-in and clock-out times. Enter a start time, end time, and unpaid break length for each day, along with your hourly rate and overtime rules, and it returns regular hours, overtime hours, regular pay, overtime pay, and gross pay for the week.

How to Use It

Fill in the start and end time for each day you worked, plus any unpaid lunch or break time in minutes — the calculator subtracts breaks and shows hours worked per day automatically. Set your hourly rate, the weekly hours after which overtime kicks in, and the overtime multiplier (1.5 for standard time-and-a-half), and the summary updates with your full pay breakdown.

When to Use It

Use it to double-check a paycheck against your actual hours, to estimate weekly earnings from an irregular schedule, or to plan how many hours to pick up before crossing into overtime. It's also handy for freelancers and hourly contractors reconstructing a timesheet from memory or a calendar.

Who Benefits

Hourly employees, shift workers, freelancers, and small business owners running payroll all benefit from not having to manually convert AM/PM clock times and subtract breaks across seven days by hand — a process where small arithmetic mistakes are easy to make.

Frequently Asked Questions

Enter your clock-in and clock-out times for each day. The calculator totals your hours and minutes, and can subtract a lunch break automatically. Results show both total time and decimal hours (useful for payroll).
In the US, federal law (FLSA) requires overtime pay of 1.5× regular rate for hours over 40 in a workweek. Some states have daily overtime rules. This calculator shows total and overtime hours separately so you can apply the correct rate.
Because clock times don't add like normal numbers — a shift from 9:45 AM to 5:15 PM isn't an obvious subtraction, and totaling five days of mixed shifts by hand is where small arithmetic errors creep into a timesheet. The calculator handles the AM/PM and minute-carrying automatically, so the total is exact every time.
