Weekly hours calculator
Add up a week of hours
Enter the hours for each day you worked and get the weekly total, with overtime over 40 flagged. Type whole hours, decimal, or hours and minutes. It runs in your browser.
Enter each day as hours (8), decimal (8.5), or hours and minutes (8:30).
Three ways to enter a day
Each day accepts whatever form you have. Type 8 for eight hours, 8.5 for eight and a half, or 8:30 for eight hours thirty minutes. They all sum into the same weekly total, shown in hours and minutes and in decimal hours for payroll.
The hours over 40 are marked as overtime, which is the federal weekly threshold. If you keep clock-in and clock-out times rather than daily totals, the time card calculator takes those directly and subtracts lunch for you.
From hours to pay
This tool stays with the hours. To convert the weekly total to decimal on its own, use the decimal hours calculator. For overtime pay and what the week is worth after tax, send the hours to Plain Paycheck, which handles the money side.
Common questions
How do I add up hours worked in a week?
Enter each day's hours and the calculator sums them. You can type whole hours (8), decimal hours (8.5), or hours and minutes (8:30) in any day, and the total shows in hours and minutes and in decimal.
How many hours is full time in a week?
Forty hours is the standard full-time week and the point where federal overtime begins. Anything over 40 in a week is flagged here as overtime at time and a half under the Fair Labor Standards Act.
Does this calculate overtime?
It flags the hours over 40 as overtime, so you can see the split between regular and overtime hours. For overtime pay, and take-home after tax, hand the hours to a paycheck calculator.
What if I already have clock in and clock out times?
Use the time card calculator instead. It takes clock-in and clock-out per day, subtracts lunch, and gives the same weekly total. This page is for when you already know the hours for each day.
