Hours worked calculator
One row per day, Monday to Sunday. Enter when you clocked in and out and any unpaid break, and the calculator shows hours for each day, the weekly total in decimal and h:mm, your average per day worked and, if you add a rate, an estimate of pay. It totals hours only; overtime is handled by the time card calculator.
Totals are hours only. For overtime and gross pay under your state rule, use the time card calculator.
How to use this calculator
- For each day you worked, enter the time you clocked in and the time you clocked out. Leave days off blank.
- Enter the length of any unpaid break in minutes. If you worked through lunch, leave the break at 0.
- Check the hours column for each day. Overnight shifts are counted on the day they started.
- Read the weekly total in decimal hours and in hours and minutes at the bottom.
- Add your hourly rate for a straight-time pay estimate. For overtime and state rules, open the time card calculator.
- Export a CSV to keep with your pay stub, or print the week.
How to calculate hours worked
For each day, subtract the clock-in time from the clock-out time and then subtract any unpaid break. Convert the result to a decimal by dividing leftover minutes by 60: 8 hours 30 minutes is 8.5 hours. Add the days together for the week. If you clock out after midnight, treat the clock-out as the next day and count the shift on the day it started.
A worked example: Monday 7:00 AM to 3:30 PM with a 30-minute lunch is 8 hours. Tuesday 7:00 AM to 5:00 PM with the same lunch is 9.5 hours. Three more 8-hour days give a week of 41.5 hours. The calculator does this for every row.
What counts as hours worked
Federal rules count all time you are required to be on duty or on the employer's premises, including short rest breaks of about 5 to 20 minutes (29 CFR 785.18). A bona fide meal period, usually 30 minutes or more, is not hours worked only if you are completely relieved of duty (29 CFR 785.19). Time spent working through lunch, waiting to be engaged, or finishing tasks after clocking out is hours worked.
Enter only unpaid meal periods in the break column. Paid rest breaks stay in your hours.
Hours worked and overtime
The Fair Labor Standards Act requires overtime pay at not less than one and one half times the regular rate for hours over 40 in a workweek (29 U.S.C. 207). The workweek is a fixed, recurring 168-hour period set by your employer, which is why this calculator is laid out as one week. This page does not split regular from overtime hours. The time card calculator applies the federal rule and state daily rules and estimates gross pay.
Keeping your own record
Employers must keep accurate records of hours worked (29 CFR 516), but the Department of Labor also encourages workers to keep their own. A weekly sheet like this one, exported each pay period, is the simplest record there is. The PunchStamp app keeps it automatically from one-tap punches and exports a dated PDF.
Frequently asked questions
How do I calculate hours worked in a week?
For each day, subtract clock-in from clock-out and subtract unpaid breaks. Convert minutes to decimals by dividing by 60. Add the days together. The calculator does this for each row and shows the weekly total in both decimal and h:mm.
How do I calculate hours worked with a lunch break?
Enter the lunch length in the break column for that day. An unpaid 30-minute lunch on an 8:00 AM to 4:30 PM shift gives 8 hours. If you worked through lunch, leave the break at 0, because that time is hours worked under federal rules.
How are hours worked calculated for payroll?
Payroll uses decimal hours. 8 hours 15 minutes is 8.25, 8 hours 20 minutes is 8.33, 8 hours 45 minutes is 8.75. Many employers also round punches to the nearest quarter hour, which is allowed under 29 CFR 785.48 if it does not short workers over time.
What if I worked an overnight shift?
Enter the clock-in and clock-out times as normal. A clock-out earlier than the clock-in is treated as the next morning, and the hours count on the day the shift started.
Does this calculator include overtime?
No. It totals straight hours and, if you enter a rate, straight-time pay. Overtime after 40 hours in a workweek, and daily overtime in states that have it, are applied by the time card calculator.
Why does my total differ from my paycheck?
Common reasons: your employer rounds punches, deducts lunch automatically even on days you worked through it, uses a different workweek start, or pays overtime on part of the hours. Compare this total with the hours on your stub first, then the rate.
Can I save my week?
The week is saved in your browser on this device. Export a CSV or print it to keep a permanent copy; clearing browser data removes the saved week.
