Timesheet Hours Calculator
Total your weekly hours from daily clock-in and clock-out times, minus unpaid breaks, split into regular and overtime hours with gross pay.

Leave a row blank to skip that day. A clock-out earlier than clock-in is read as an overnight shift.

Leave at 0 for hours only. Pay fields show $0.00.
Hours use exact-to-the-minute math and are rounded to two decimals only for display. Pay is rounded to the cent.
How to calculate weekly timesheet hours
The manual method is the same one this calculator runs for you. For each day, subtract the clock-in time from the clock-out time to get the raw span, then take out any unpaid break. Turn the leftover minutes into a decimal by dividing by 60, so 15 minutes becomes 0.25 and 30 minutes becomes 0.50. Add the seven daily figures for your weekly total, then multiply by your hourly rate for pay.
Here is how that plays out. Say an employee clocks in at 9:00 and out at 17:30 with a 30-minute unpaid lunch. The raw span is 8.5 hours (510 minutes); knock off the 30-minute break and you are left with 8.0 hours for the day. Do the same Monday through Sunday and sum the column.
| Day | In | Out | Break | Hours |
|---|---|---|---|---|
| Mon | 9:00 | 17:30 | 30 | 8.00 |
| Tue | 9:00 | 17:30 | 30 | 8.00 |
| Wed | 9:00 | 18:00 | 30 | 8.50 |
| Thu | 9:00 | 17:30 | 30 | 8.00 |
| Fri | 9:00 | 17:00 | 30 | 7.50 |
| Weekly total | 40.00 | |||
Overnight shifts work too. If the clock-out lands earlier than the clock-in (say 22:00 to 06:00), the calculator adds 24 hours so the span reads as 8 hours instead of a negative number.
Overtime, breaks, and rounding rules
Under the FLSA, non-exempt employees earn overtime at no less than 1.5 times their regular rate for every hour worked past 40 in a single workweek. Hours up to the threshold are regular; the rest is overtime. There is no federal daily-overtime requirement, so federal overtime is a weekly calculation. Some states go further. California, for instance, adds 1.5x pay after 8 hours in a day and 2x after 12 hours, so check your state rules if you work there.
Unpaid meal periods of 30 minutes or more, where the employee is fully relieved of duty, are not hours worked, which is why you deduct them. Short rest breaks of 5 to 20 minutes are paid time and should stay in. Employers may also round each clock punch to the nearest quarter-hour under the 7-minute rule: minutes 1 to 7 round down and 8 to 14 round up, applied neutrally so it never quietly shortchanges the worker. This tool keeps the exact minute math and leaves rounding as a policy choice. You can model employer-side costs on those hours with the Employer Cost Calculator or the SUTA / FUTA Employer Tax Calculator.
From hours to gross pay, and to take-home pay
Weekly hours times your hourly rate (with overtime paid at the multiplier) gives gross pay, which is what this calculator reports. But gross pay is only the starting point. Federal income tax, state income tax, and FICA (Social Security and Medicare) come out before the worker sees a paycheck. To turn these hours into net pay, run the number through the Salary to Paycheck Calculator or the 401(k) Paycheck Impact Calculator.
For recurring or multi-employee payroll, carry these hours into the Multi-Employee Payroll Total Calculator or the WorkLogs44 app, which runs full payroll with federal, state, and FICA math plus employer SUTA and FUTA across your whole team.
Frequently Asked Questions
Common questions about timesheet hours calculator
How do I calculate timesheet hours manually?
For each day, subtract the clock-in time from the clock-out time, then take out any unpaid break. Turn the leftover minutes into a decimal by dividing by 60 (15 min = 0.25, 30 min = 0.50). Add the seven daily totals for your weekly hours, then multiply by your hourly rate.
How do I convert minutes to decimal hours?
Divide the minutes by 60 and add that to the whole hours. So 8 hours 30 minutes = 8 + (30 / 60) = 8.5 decimal hours, and 15 minutes = 0.25 hours. Payroll systems use decimal hours because they multiply cleanly by an hourly rate.
What is the 7-minute rounding rule?
The FLSA lets employers round each clock punch to the nearest quarter-hour. Minutes 1 to 7 past a quarter-hour round down; minutes 8 to 14 round up. Each clock-in and clock-out is rounded on its own, and the rounding has to be neutral so it does not shortchange the employee over time.
Are unpaid lunch breaks deducted from timesheet hours?
Yes. Bona fide meal periods (usually 30 minutes or more) where the employee is fully relieved of duty do not count as hours worked, so you subtract them from the daily total. Short rest breaks of 5 to 20 minutes are different: they count as paid work time.
How is overtime calculated over 40 hours a week?
Under federal law, non-exempt employees earn at least 1.5x their regular rate for every hour worked past 40 in a single workweek. Hours up to 40 are regular; anything over that is overtime. Federal law does not require daily overtime.
Does California have daily overtime rules?
Yes. California pays 1.5x after 8 hours in a workday and after 40 hours in a week, and 2x after 12 hours in a workday or after 8 hours on the seventh straight day of work. A handful of states set their own daily overtime rules that go past the federal weekly standard.
What is the difference between the 12-hour and 24-hour (military) time format?
12-hour format uses am/pm (for example 5:00 pm), while 24-hour or military time counts straight through (17:00). This calculator takes either one; the math comes out the same because both get converted to minutes past midnight internally.
Does this timesheet calculator save my data?
No. The math runs entirely in your browser, and nothing is stored or sent anywhere, so once you close the tab your entries are gone. For recurring, multi-employee payroll you can carry the hours into the WorkLogs44 app.
