Timesheet Calculator
An out-time before the in-time is an overnight shift.
Work out Timesheet. An out-time before the in-time is an overnight shift. Names the misconception directly.
Gross pay for the week
800.00
40 h worked · 40 decimal hours
Decimal hours are what payroll systems want: 8 hours 30 minutes is 8.5, not 8.30. Entering 8.30 into a payroll field pays eighteen minutes short every time it happens.
How the Timesheet Calculator works
A week of clock-in and clock-out times with breaks deducted, totalled in hours, decimal hours and pay. An end time earlier than the start is read as an overnight shift and gets a day added, rather than coming out negative.

Overnight shifts and the negative-hours bug
Subtracting a start time from an end time works until the shift crosses midnight, at which point 22:00 to 06:00 comes out as minus sixteen hours. Every naive timesheet has this bug, and the people it affects are night shift workers — precisely the group least able to spot it on a summary total.
The fix is to add twenty-four hours to the end time when it is at or before the start, which turns minus sixteen into eight. This page does that automatically and marks the day as overnight so the adjustment is visible rather than silent.
The edge case worth flagging is a shift that genuinely runs 24 hours or a mistyped entry where start and end are identical. Both are read as zero-length rather than as a full day, on the basis that a wrong zero is easier to notice than a wrong twenty-four.
Breaks, and what counts as working time
Whether a break is paid depends on its length and on jurisdiction. Short rest breaks are frequently paid and count as working time; longer meal breaks frequently are not. The test is usually whether you are genuinely free to use the time as your own.
Working through an unpaid break is working time in most systems, and a timesheet that always records the scheduled break regardless of what happened is how that time silently goes unpaid. Recording what actually occurred is the whole value of keeping a timesheet.
On-call time sits in a large grey area that has been litigated repeatedly. Being required to remain at the workplace generally counts as working time; being contactable at home generally does not; and a great many arrangements fall between the two with answers that differ by country.
Records, rounding and disputes
Employers are typically required to retain wage and hour records for several years. For an employee, keeping a contemporaneous personal copy is what converts a disagreement into a documented one, and contemporaneous records carry weight that later reconstructions do not.
Rounding is lawful in many places when applied neutrally. Rounding to the nearest quarter hour averages out over time; rounding that only ever goes down costs roughly seven minutes per entry, which across 250 working days is about four days of unpaid work a year.
Corrections should leave a trail. Amending an entry with a note is normal practice; an unexplained edit that changes hours actually worked is a serious matter, and it is only ever noticed by someone who kept their own record of what the entry originally said.

Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time and deduct unpaid breaks. Nine to five-thirty with a thirty-minute break is eight hours. For an overnight shift, add twenty-four hours to the end time first.
How do I convert hours and minutes to decimal?
Divide the minutes by sixty. Eight hours thirty minutes is 8.5, not 8.30. Typing 8.30 into a payroll field pays eighteen minutes short every time.
How does this handle a night shift?
An out-time at or before the in-time is treated as the following day, so 22:00 to 06:00 with a one-hour break comes out at seven hours rather than a negative number.
Are breaks paid or unpaid?
It depends on jurisdiction and length. Short rest breaks are frequently paid while longer meal breaks frequently are not, and rules on who may require you to stay on site vary. Enter only the unpaid time here.
What time format should I use?
Twenty-four hour, as HH:MM — 09:00 and 17:30. It removes the am/pm ambiguity that causes most timesheet errors, particularly around midnight and noon.
Should I round my hours?
Only if your employer's policy says so, and rounding must be neutral rather than always in the employer's favour. Rounding to the nearest quarter hour is common and lawful in many places when applied evenly.
How long do I need to keep timesheets?
Employers are typically required to retain wage and hour records for several years, and the exact period varies. As an employee, keeping your own copy is what turns a dispute into a documented one.
Can my employer change my timesheet?
Corrections for genuine errors are normal; altering hours actually worked is not, and an unexplained edit is a serious matter. Keeping your own contemporaneous record is the reason such changes get noticed.
Does travel between sites count?
Travel between work locations during the working day generally counts as working time. The ordinary commute to a fixed workplace generally does not.
What is the seven-minute rule?
A quarter-hour rounding convention: time within seven minutes of a quarter hour rounds to it. It is lawful in many places when applied evenly in both directions, and unlawful when it only ever rounds down.
How do I record a split shift?
As two separate entries with the unpaid gap between them excluded. Recording it as one long shift with a very long break usually works arithmetically but obscures what happened.
Should I record breaks I did not take?
Record what actually happened. Working through an unpaid break is working time in most systems, and a timesheet that always shows the scheduled break regardless is how that time goes unpaid.
