Elapsed Time Calculator

Calculate elapsed hours between two clock times, allowing for breaks.

About Elapsed Time Calculator

Subtracting start from end gives the span; a shift that crosses midnight wraps by adding 24 hours. Unpaid breaks come off the total, and the decimal-hours figure is what payroll systems expect rather than hours and minutes. Payroll rounding disputes almost always trace back to breaks and decimal conversion, and an overnight shift computed naively comes out negative.

Formula

Elapsed Time

Hours = (end − start) − breaks, summed across days

start
Clock-in time
end
Clock-out time
breaks
Unpaid break minutes

Worked example

With the default values below, Elapsed Time Calculator returns Hours per Day of 8.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Elapsed Time calculated?

Hours = (end − start) − breaks, summed across days Subtracting start from end gives the span; a shift that crosses midnight wraps by adding 24 hours. Unpaid breaks come off the total, and the decimal-hours figure is what payroll systems expect rather than hours and minutes.

Why does Elapsed Time matter?

Payroll rounding disputes almost always trace back to breaks and decimal conversion, and an overnight shift computed naively comes out negative.

What values do I need to enter?

This calculator takes 4 inputs: Start time (24-hour clock), End time (24-hour clock), Unpaid break, Number of days. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
