Timesheet Calculator

What Is the Timesheet Calculator?

This calculator sums a full week's daily hours -- Monday through Sunday -- into a weekly total, average hours per working day, and gross pay at your hourly rate, the same summary a weekly timesheet produces.

How to Use This Calculator

Enter hours worked for each day of the week and your hourly rate. The result shows total hours, average hours per day worked, and gross pay for the week.

How the Total Is Calculated

Worked Example

Practical Uses

• Cross-checking a weekly timesheet before submitting it to payroll
• Estimating a week's gross pay before an official paycheck is issued
• Tracking hourly work across an irregular weekly schedule

To split the weekly total into regular and overtime hours, see the Overtime Hours Calculator. For billable-hours invoicing with non-billable time excluded, use the Billable Hours Calculator.

A Worked Example With an Irregular Week

Suppose a part-time worker logs Monday 6.5, Tuesday 0, Wednesday 7.25, Thursday 4, Friday 8, Saturday 3.5 and Sunday 0 hours, at a hypothetical rate of $18 per hour. The total is 29.25 hours. Gross pay is 29.25 multiplied by 18, or $526.50. Only five days have nonzero entries, so the average per day worked is 29.25 divided by 5, or 5.85 hours. Notice that the average is not 29.25 divided by 7 (4.18 hours); the tool deliberately ignores days left at zero.

Converting Clock Times to Decimal Hours

The calculator expects decimal hours, not hours and minutes. Clock time such as 7 hours 45 minutes must be converted before you type it in: divide the minutes by 60 and add them to the hours. Forty-five minutes is 0.75, so the entry is 7.75. The most frequent mistake on any timesheet is typing 7.45 for 7 hours 45 minutes, which is really 7 hours 27 minutes. Some quick conversions:

• 15 minutes = 0.25 hours
• 30 minutes = 0.5 hours
• 45 minutes = 0.75 hours
• 10 minutes = about 0.17 hours (0.1667 exactly), so rounding slightly changes the total

Subtract Unpaid Breaks Before Entering Hours

Each daily entry should be paid time. If you clocked in at 9:00 and out at 5:30 with a 30-minute unpaid lunch, enter 8, not 8.5. The tool has no field for breaks, so it will pay whatever you type. If your employer rounds punches to the nearest quarter hour or similar, use the rounded figures your payroll actually uses, otherwise your estimate will drift from the real paycheck.

Interpreting the Gross Pay Result

Gross pay is the amount before any withholding. Federal and state income tax, Social Security and Medicare contributions, benefit premiums and retirement deferrals all reduce it, so the deposit that reaches your bank will be lower. The calculator applies one flat rate to every hour, so it will understate pay if some of your hours qualify for overtime, a shift differential or a different job rate. In that case split the hours into groups and run them separately or use the related overtime and differential tools.

Common Reasons the Numbers Do Not Match Payroll

• Your employer uses a different workweek definition, for example Sunday to Saturday versus Monday to Sunday, so hours near the boundary land in another week.
• Rounding rules at clock-in and clock-out add or remove a few minutes per day.
• Overtime, holiday premiums or tips are paid on top of the base rate.
• A paid holiday or sick day appears on payroll but was never entered here.

If a discrepancy is more than a few cents of rounding, keep your own record of hours and ask your payroll or HR contact to explain the difference. Wage and hour rules vary by state, and the US Department of Labor or your state labor agency is the authoritative source if you believe you were underpaid.

Using It for Planning as Well as Checking

Because the tool only needs hours and a rate, you can also run scenarios before the week starts: enter your planned schedule to see what a shift swap or an extra Saturday would add to gross pay. Multi-week averages are easy too, since you can total each week separately and compare the results.
