The decimal-hours table payroll actually reads

Nobody's timesheet says "7.5". It says 7:30, and somebody, a spreadsheet or a person, has to turn that into the decimal a pay rate can multiply against. This tool does that conversion behind the scenes every time you type a day's hours, so the table below is the reference it is quietly using.

Clock readingDecimal hours
7 h 15 m7.25
7 h 30 m7.50
7 h 45 m7.75
8 h 20 m8.33
8 h 40 m8.67

The rule behind every row is the same: minutes divided by 60. Twenty minutes is 0.33, not 0.20, which is the single most common typing error on a manual timesheet. Get that division wrong five days running and a week that should read 40.00 quietly turns into something else.

FLSA baseline: non-exempt employees get at least 1.5 times their regular rate for hours worked over 40 in a workweek, per the Department of Labor.

Where the 40-hour line comes from

The Fair Labor Standards Act sets the overtime threshold at 40 hours in a single workweek, a fixed, recurring 168-hour period that does not have to match the calendar week. Go over it and every hour past 40 is paid at one and one-half times the regular rate for covered, non-exempt workers. A 46-hour week is 40 regular hours plus 6 overtime hours; at a $20 rate that is $800 regular plus $180 overtime (6 times $30), for $980 gross. A handful of states, California among them, layer a daily overtime rule on top, so a long single day can trigger overtime even in a week that stays under 40 total.

Running the numbers on a real week

Log 8, 9, 8, 9 and 8 hours Monday through Friday and the total is 42. The first 40 sit at the regular rate, the last 2 at time and a half. At $18 an hour that is 40 times $18 for $720 regular, plus 2 times $27 for $54 overtime, for $774 gross before anything gets withheld. Change any single day and the split recalculates instantly above; nothing here is hardcoded to this example.

Things to know

First, it is gross pay, not take-home. What lands in your account depends on withholding, filing status and deductions this tool never sees. Second, a paid day off does not add to the 40-hour count. Overtime is measured against hours you actually worked, so a holiday or a vacation day your employer still pays you for sits outside the calculation entirely, even though it appears on your check.

Save the week before you close the tab

The print button above turns your seven entries, the weekly total and the regular/overtime split into a clean printable page, stripped of the site header, navigation and ads. Useful for a paper timesheet, an email attachment, or just a record you keep for yourself alongside a pay stub.

Questions people ask about weekly totals

Why does the rate field say optional?

Because the weekly total and the regular/overtime split work with hours alone. Add a rate only if you want the gross pay line filled in too.

I worked a split shift, two blocks in one day. How do I enter that?

Add the two blocks yourself and type the sum into that day's field. Each day here takes one number, not a start and end time; use the time card calculator if you want to enter clock times per block instead.

Can I save or print the week I just built?

Yes. The print button below the results formats your seven entries, the weekly total, and the regular/overtime split into a plain printable summary, with the calculator chrome left out.

Does paid vacation or a holiday count toward the 40-hour line?

No. The 40-hour overtime threshold is built from hours actually worked. A paid day off does not add to that total even though it shows up on a pay stub.

Is 40 hours a legal definition of full-time?

No such federal definition exists. Forty hours is simply the point where FLSA overtime starts; individual employers set their own full-time cutoff, often 30 to 40 hours.

Does this tool keep anything I type?

No. Everything runs in your browser tab and disappears when you close it or hit print.
