Timesheet period

Use 24-hour time (09:00, 17:30). Breaks are unpaid minutes. This sheet assumes your employer’s workweek starts Monday at 00:00.

An earlier clock-out means the next day. Equal times mean zero hours. Use 24:00 to end a shift at midnight. Split shifts at the workweek boundary; the final row cannot carry hours into the next week.

42 + 38 doesn’t mean zero overtime.

That’s 80 hours across two weeks, but the first week still has 2 overtime hours. We keep each week separate.

Federal weekly rulesState and special industry rules may differ.

Grounded in official guidanceQualified overtime is the premium required by FLSA Section 7. Higher contractual premiums don’t automatically qualify.

BEHIND THE NUMBERS

Start with the time you clocked in and out. Enter only breaks that are properly unpaid, then review the daily and weekly totals before using them to estimate pay.

01

How your timesheet hours are calculated

For each shift, subtract the start time from the end time and then subtract unpaid break minutes. An end time earlier than the start time is treated as the following day. Check overnight entries carefully so an accidental time reversal is not mistaken for a night shift.

Hours and minutes are different from decimal hours: 7 hours and 30 minutes is 7.5 hours, not 7.30 hours. Keep the original clock times when checking payroll; rounding displayed totals should not change the minutes you actually entered.

THE FORMULAPaid shift hours = (elapsed shift minutes − unpaid break minutes) ÷ 60
02

Subtract unpaid meals, keep paid rest breaks

Short rest breaks generally count as paid work time under federal law. A bona fide unpaid meal period generally requires you to be completely relieved of duties. Entering every break as unpaid can understate both your paid hours and overtime.

If you continued working during lunch, do not assume the entire lunch period can be deducted. Use your actual records and the applicable work-time rules. This calculator performs arithmetic on the break minutes you enter; it does not decide whether a break is legally unpaid.

03

Keep overtime within its own workweek

The standard federal calculation uses hours worked over 40 in each workweek. When entering two weeks, preserve your employer's workweek boundaries. Do not combine all hours first and apply an 80-hour threshold.

This is a general weekly hours tool. It does not apply state daily overtime rules, special work periods, or daylight-saving clock changes automatically. Use the reviewed weekly totals in the overtime pay calculator, then check whether any overtime premium is eligible for the separate federal deduction.

GOOD QUESTIONS

A little more
clarity.

Plain answers to the things that can make overtime confusing.

How do I convert minutes to decimal hours?

Divide the minutes by 60. For example, 15 minutes is 0.25 hours, 30 minutes is 0.5 hours, and 45 minutes is 0.75 hours.

Can I enter an overnight shift?

Yes. If the end time is earlier than the start time, the calculator treats it as the next day. It is intended for shifts shorter than 24 hours; verify the result against your actual shift.

Should I subtract a paid rest break?

No. Paid rest breaks remain in work hours. Only enter break minutes that can properly be excluded from paid work time.

Does an unpaid lunch reduce overtime hours?

A properly unpaid meal period is excluded from hours worked, which can affect weekly overtime. A meal period during which you are not completely relieved of duties may need to remain in paid time.

Why does an 80-hour timesheet show overtime?

A biweekly total can include a week over 40 hours and another below 40. Under the usual federal rule, the shorter week does not cancel overtime earned in the longer week.

Does the calculator decide whether I qualify for overtime?

No. It separates hours using a standard weekly threshold. Your FLSA status, state law, and any special work-period rules determine the pay rules that actually apply.
