Timesheet Calculator

Calculate total worked time from a start time, end time, and break duration.

Before you calculate

A quick overview to help you understand what this tool does and how to use it well.

Use this timesheet calculator to estimate the amount of time worked during a shift after subtracting breaks. This is useful for payroll checks, daily work logs, personal time tracking, shift planning, and simple timesheet review before submitting hours.

By entering the time you started working, the time you stopped, and the total break duration in minutes, you can quickly see your net worked time without calculating it by hand.

Inputs

Results

Your result updates after a successful calculation.

Worked hours

8

Full worked hours after breaks are removed.

Remaining worked minutes

30

Minutes left after full worked hours are counted.

Total worked minutes

510

Net worked time converted fully into minutes.

Worked time summary

8 hours 30 minutes

Readable net worked time after subtracting breaks.

Shift note

Calculated within the same day after subtracting breaks.

Summary of whether the shift stayed in one day or crossed midnight.

How it works

See the formula, calculation method, and reasoning behind the result.

This tool calculates shift length from a start time and end time, then subtracts the break duration to return the net worked time.

The process works like this:

  • you enter the shift start time
  • you enter the shift end time
  • the calculator determines the full shift duration
  • if the shift crosses midnight, it accounts for that automatically
  • it subtracts the total entered break time
  • it returns the net time worked

This helps because work shifts are easy to miscalculate by hand, especially when overnight hours or deducted breaks are involved.

Worked example

Calculate net worked time for a shift that starts at 8:00 AM, ends at 5:00 PM, and includes a 30-minute break. This is a common timesheet use case where the gross shift length needs to be reduced by the break before hours are reported.

  • startTime: 08:00
  • endTime: 17:00
  • breakMinutes: 30

Example results

  • Worked time: 8 hours 30 minutes
  • Total worked minutes: 510

FAQ

Common questions about this tool.

Does this subtract break time?

Yes. The break duration you enter is subtracted from the total shift length to show net worked time.

Can it handle overnight shifts?

Yes. If the end time is earlier than the start time, the calculator treats the shift as crossing midnight into the next day.

When would I use a timesheet calculator?

A timesheet calculator is useful for checking payroll hours, reviewing time cards, logging work sessions, planning staffing, and estimating net work time after breaks.

What should I enter for break duration?

Enter the total unpaid or deducted break time in minutes for the full shift. For example, a 30-minute lunch break should be entered as 30.

Can break time be longer than the shift?

No. If break time is longer than the total shift length, the input should be corrected because net worked time cannot be negative.

Why show both hours and total minutes?

Some timesheets and payroll systems use hours and minutes, while others rely on total minutes for easier conversion and reporting.
