This free timesheet calculator totals your hours for a weekly or biweekly pay period. Enter your start time, end time, and break for each day, and the tool calculates daily hours, a total for each week, overtime calculated separately for each week, and gross pay if you add an hourly rate.
How to use the timesheet calculator
- Choose weekly (7 days) or biweekly (14 days).
- Enter start time, end time, and break minutes for each day worked.
- Add an hourly rate if you want a gross pay estimate.
- Check the overtime multiplier and the weekly overtime threshold.
- Read the total for each week and for the whole pay period.
Example: why weeks are calculated separately
Imagine a biweekly timesheet with 44 hours in week one and 36 hours in week two. That is 80 hours in total, but overtime is figured per week. Week one has 4 overtime hours and week two has none. At $20 per hour and 1.5x overtime, pay is 40 x $20 + 4 x $30 = $920 for week one and 36 x $20 = $720 for week two, so $1,640 gross.
How a biweekly timesheet is calculated
Daily hours equal end time minus start time minus break. Each week is totaled on its own. Within a week, hours above the threshold (40 by default) are overtime and are paid at your rate times the multiplier. Pay for the period is the sum of both weeks. Averaging 40 hours across two weeks does not remove overtime when one week goes over.
Frequently asked questions
How do I calculate a biweekly timesheet?
Total the hours for each of the two weeks separately, work out overtime within each week, then add the two weeks together.
Is overtime calculated per week or per pay period?
Under US federal rules, overtime is generally based on each fixed workweek, not the whole pay period. Some states and employers add daily overtime rules, so check yours.
How do I add up hours and minutes on a timesheet?
Add the hours, add the minutes, then carry every 60 minutes into one hour. This calculator does that for you.
Can I use this for a semi-monthly pay period?
Use the biweekly mode for two-week periods. For other periods, calculate each week and add the results together.
Is the result gross or net pay?
Gross. It does not subtract taxes, insurance, or other deductions.
