Timesheet Calculator
Add weekly shifts, breaks, overtime threshold, and hourly rate to estimate timesheet totals and gross pay.
Formula
Daily Hours = End Time - Start Time - Break Time
Weekly Hours = Sum of Daily Hours
Overtime Hours = Weekly Hours - Threshold Complete example
Five 8:00 AM to 6:00 PM days with 30 minute breaks create 47.5 hours. With a 40 hour threshold, 7.5 hours are overtime.
When to use this calculator
- Review a weekly timesheet.
- Estimate gross pay before payroll.
- Check overtime exposure before submitting hours.
How to interpret the results
Regular and overtime hour splits are planning estimates. Actual pay depends on employer policy and applicable rules.
Common mistakes
- Using one overtime threshold for every jurisdiction.
- Leaving partial days blank without checking totals.
- Confusing total elapsed hours with paid hours.
How to calculate a weekly timesheet
A weekly timesheet should be calculated day by day. First calculate each day from clock-in time, clock-out time, and unpaid break minutes. Then add the daily paid hours into a weekly total. Only after the weekly total is clear should you compare it with the overtime threshold entered in the calculator.
This order matters because daily mistakes can hide inside a weekly total. A missing lunch break, an incorrect overnight entry, or a copied start time can change overtime and pay estimates. Reviewing the daily rows makes the final number easier to trust.
- Calculate daily paid hours.
- Add daily hours into the week.
- Compare the weekly total to the threshold used for the estimate.
Complete weekly example
Imagine a week with five shifts from 8:00 AM to 6:00 PM and a 30 minute unpaid break each day. Each day has 10 elapsed hours minus 30 minutes, which equals 9.5 paid hours. Five days at 9.5 hours each produce a 47.5 hour week.
With a 40 hour threshold, the calculator reports 40 regular hours and 7.5 overtime hours. At $20 per hour and a 1.5x overtime multiplier, regular pay is $800.00 and overtime pay is $225.00, for an estimated gross pay of $1,025.00. The estimate is useful for planning, but payroll should still apply the relevant rules and deductions.
How to read regular and overtime totals
Regular hours are the portion of the week at or below the threshold you entered. Overtime hours are the portion above that threshold. If the threshold is 40 and the weekly total is 38.25, the overtime result should be zero. If the weekly total is 44.00, the overtime result should be 4.00 hours.
The calculator does not know whether a daily overtime rule, holiday rule, contract rule, or alternate schedule applies. It gives a transparent threshold-based split so you can see the math before applying payroll policy.
Timesheet review checklist
Before using a weekly result, compare each row with the source record. Confirm that each workday has the right start time, end time, and unpaid break. Check blank days intentionally. Verify that overnight shifts were entered with the correct end time. Then check whether the overtime threshold and hourly rate match the situation being reviewed.
This checklist is especially important for contractors and small teams using manual timesheets. A calculator can prevent arithmetic mistakes, but it cannot confirm whether a person actually worked the hours entered.
What to save with the weekly summary
A weekly timesheet summary is more useful when it includes the assumptions behind the total. Save the pay period or week label, each daily entry, the unpaid break minutes, the hourly rate used for the estimate, and the overtime threshold. If someone reviews the number later, these details explain why the result appears the way it does.
For official payroll, the source record and approval process matter as much as the arithmetic. TimesheetKit can show the calculation trail, but it does not replace payroll approval, HR review, or employer-specific recordkeeping.

FAQ
Does this apply state labor law?
No. It uses the threshold you enter and is not legal or payroll advice.
Can I use it for contractors?
Yes, as a planning tool for billable hours and gross totals.
Does it round clock times?
No. It uses the exact times you enter.
