Timesheet and Payroll Calculator – Hours, Overtime and Pay

What is a timesheet and payroll calculator?

A timesheet records the hours worked in a day or a week. A payroll calculation turns those hours into pay. This tool combines both. Enter the start time, end time and unpaid break for each day, then set an hourly rate, an overtime threshold, an overtime multiplier and an estimated tax percentage. The calculator shows total hours, regular and overtime hours, gross pay, estimated tax and estimated net pay. You can print a neat weekly timesheet for your records or to give to an employer or client.

How the calculation works

For each day, the tool subtracts the start time from the end time and takes away your unpaid break. Shifts that end after midnight are handled automatically, so a shift from 22:00 to 06:00 counts as eight hours. Weekly hours are added up. Hours up to your overtime threshold, commonly 40 a week, are paid at the regular rate. Hours above the threshold are paid at the regular rate multiplied by the overtime multiplier, for example 1.5 for time and a half. Tax is a simple percentage of gross pay, which is a rough guide for planning.

Who uses this calculator

• Employees who want to check that their payslip matches the hours they worked.
• Freelancers and contractors billing by the hour.
• Small business owners who need a quick weekly pay estimate for hourly staff.
• Students and part-time workers who track shifts across several jobs.
• Parents and household employers who pay nannies or cleaners by the hour.

Tips for accurate timesheets

• Record times at the end of each shift, not from memory at the end of the week.
• Always include unpaid breaks so you do not overstate hours.
• Check local rules for overtime, rest periods and rounding. Some places have daily overtime, not only weekly.
• Keep a printed or PDF copy of each weekly timesheet together with your payslips.
• If you bill clients, round to the increment in your agreement, such as 15 minutes.

Common mistakes to avoid

• Entering 12-hour times without checking am and pm; the time fields use the 24-hour clock on most devices.
• Forgetting the break on long days.
• Using the tax estimate as a final figure. Real tax depends on allowances, deductions and local rules.
• Mixing paid and unpaid travel time without checking your agreement.

Privacy and limits

Your hours and rates stay in this browser and are not uploaded. The tool remembers the last week you entered on this device. It handles a single week at a time and does not include benefits, insurance, pensions or deductions other than the percentage you enter. Use it for estimates, and rely on your payroll provider or accountant for official payroll.
