Weekly timesheet

Leave days you did not work empty. An end time earlier than the start time counts as an overnight shift.

Leave the rate empty to see hours only. Empty threshold and multiplier use 40 hours and 1.5.

How to use the calculator

For each day you worked, enter the start time, the end time and any unpaid break in minutes. Leave the days you did not work empty. Then press Calculate.

To estimate your pay, add your hourly rate. You can also change when overtime starts (40 hours a week by default) and the overtime multiplier (1.5 by default, often called time and a half). Without a rate the calculator shows hours only.

The result table lists the hours for each day in two forms, hours and minutes (h:mm) and decimal hours, followed by the weekly total split into regular and overtime hours.

How the hours are calculated

  1. Daily hours = end time − start time − unpaid break.
  2. If the end time is earlier than the start time, the shift is treated as overnight and ends on the next day. A shift from 22:00 to 06:00 is 8 hours.
  3. Weekly total = the sum of all days.
  4. Overtime = the weekly hours above the threshold. Everything up to the threshold is regular time.
  5. Pay = regular hours × rate + overtime hours × rate × multiplier, rounded to cents.

Worked example

You work Monday to Friday from 8:00 to 17:30 with a 30-minute unpaid lunch. Each day is 9 hours, so the week is 45 hours: 40 regular hours and 5 overtime hours. At a rate of 20.00 per hour with a 1.5 multiplier, regular pay is 800.00, overtime pay is 5 × 20 × 1.5 = 150.00, and the estimated total is 950.00.

Good to know

  • The pay figure is an estimate of gross pay before taxes, deductions and benefits. Your employer's payroll may round time differently, for example to the nearest quarter hour.
  • Overtime rules differ. This tool uses a weekly threshold only. Some places and contracts also pay overtime after a set number of hours per day, or pay more on weekends and holidays. Check the rules that apply to your job.
  • Breaks are whole minutes and must be shorter than the shift. Paid breaks should not be entered, because they count as working time.
  • h:mm versus decimal. 7:45 means 7 hours 45 minutes, which is 7.75 decimal hours. Payroll systems usually ask for the decimal form.
  • An overnight shift is counted in full on the day it starts, so a Sunday night shift stays in this week's total.
  • Daylight saving changes are not applied; every shift is measured on a normal 24-hour clock.

Frequently asked questions

How do I enter a night shift that ends after midnight?

Enter the times as they appear on the clock, for example a start of 22:00 and an end of 06:00. Because the end is earlier than the start, the calculator counts it as an overnight shift and gives 8 hours, all on the day the shift started.

How is overtime calculated?

All hours worked in the week above the threshold count as overtime. With the default of 40 hours, a 45-hour week has 40 regular hours and 5 overtime hours. Overtime hours are paid at the hourly rate times the multiplier, which is 1.5 unless you change it.

What is the difference between 8:30 and 8.5 hours?

They are the same amount of time written two ways. 8:30 is 8 hours and 30 minutes; 8.5 is the decimal form, because 30 minutes is half an hour. The table shows both so you can copy whichever your timesheet needs.

Is the pay result my take-home pay?

No. It is an estimate of gross pay for the hours entered. Taxes, social security, pension contributions and other deductions are not included, and your employer may round hours differently.
