🕒 Time Card Calculator
If you already know each day's hours, skip the clock-in math: type the five daily totals and get the week's sum with overtime (anything over 40 hours) broken out separately.
The 40-hour overtime threshold matches the US federal standard; adjust mentally if your contract uses a different one.
How to use this calculator
Type the hours you worked each weekday and the calculator totals the week, splitting regular hours from overtime over 40.
- Enter the hours for Monday through Friday; use decimals like 7.5 for partial hours.
- Leave a day at 0 if you did not work it.
- The weekly total appears instantly.
- Read the regular hours and the overtime hours separately.
Frequently asked questions
What does the Time Card Calculator compute?
It adds your five daily hour entries into a weekly total, then splits it into regular hours (up to 40) and overtime hours (anything above 40).
Can you give a worked example?
Entering 8, 8, 8, 9 and 7 gives 40 total hours with 0 overtime. Entering 9 hours on all five days gives 45 total, split into 40 regular and 5 overtime hours.
What overtime rule is used?
The 40-hour weekly threshold from the US federal standard. If your contract uses a different threshold, compare the total against it yourself.
Can I enter partial hours?
Yes. The fields accept quarter hours and other decimals, so 7.5 for seven and a half hours works fine.
