Hours Calculator

Type the clock-in and clock-out time and the break for each day of a one or two week pay period and read the hours worked per day, the total in hours and minutes and as a decimal, and the split between regular, overtime and double time. The default is the US federal rule, time and a half after 40 hours in a week; add a daily limit for states such as California or for your contract, round shifts to the nearest 5, 6 or 15 minutes if your employer does, and type an hourly rate to see gross pay. Copy the finished sheet as text or print it.

How it works

Hours Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.

Time Card Calculator · Overtime Calculator

From clock times to paid hours

A time sheet is a list of shifts, and each shift is the clock-out time minus the clock-in time, less any unpaid break. This calculator does that for every day of a one or two week pay period, handles a shift that runs past midnight, and adds the days up as hours and minutes and as a decimal, which is what payroll software and most pay slips use (7:30 is 7.50 hours, 7:45 is 7.75). Type a break in minutes, since that is how most employers record it.

Overtime

Under the US Fair Labor Standards Act (29 U.S.C. 207), employees who are not exempt must be paid at least one and a half times their regular rate for hours over 40 in a workweek. That is the default here, and it is applied to each week separately, which matters for a two-week period: 45 hours one week and 35 the next is five hours of overtime, not zero. Some states add a daily rule. California, for example, pays time and a half after eight hours in a workday and double time after twelve, and for the seventh consecutive day worked in a week (California Department of Industrial Relations overtime FAQ, read 4 October 2026). Set the daily limits in Overtime rules to apply them; the calculator takes a day's overtime first and only counts the remaining regular hours towards the weekly 40, so no hour is paid as overtime twice. Contracts and other countries have their own thresholds; type whichever applies to you.

Rounding

US regulations allow an employer to round clock times to the nearest five minutes, tenth of an hour or quarter of an hour, provided the rounding works both ways over time and does not short the employee (29 CFR 785.48(b)). The rounding option here rounds each shift's length, which is the usual practice; leave it off to use the exact minutes. Quarter-hour rounding is the one most people mean by "the seven-minute rule": 7 minutes round down, 8 round up.

What the pay figure is

Gross pay is regular hours at the rate, overtime at the multiplier and double time at twice the rate, before tax and deductions. It assumes one hourly rate; shift differentials, bonuses and piece rates change the "regular rate" that overtime is based on under federal law, and are not worked out here. Nothing you type is sent anywhere or kept; copy or print the sheet if you need to hand it in.

• Breaks in minutes, and shifts that run past midnight
• Weekly overtime after 40 hours, or any limit you set, at 1.5 times or your own rate
• Optional daily overtime and double time, applied before the weekly limit
• Rounding to the nearest 5, 6 or 15 minutes, or exact minutes
• Hours and minutes and decimal hours, gross pay, copy as text, print

Questions

How do I add up hours worked?

For each shift, take the clock-out time minus the clock-in time and subtract the unpaid break, then add the shifts. 9:00 to 5:30 with a 30 minute break is 8 hours. The calculator does it for every day and totals the week in hours and minutes and as a decimal.

How do I convert minutes to decimal hours?

Divide the minutes by 60: 15 minutes is 0.25, 30 is 0.50, 45 is 0.75, and 7:20 is 7.33 hours. The total is shown both ways so it matches a time clock and a pay slip.

When does overtime start?

Under the US Fair Labor Standards Act (29 U.S.C. 207), after 40 hours in a workweek, at not less than one and a half times the regular rate, for employees who are not exempt. Some states add daily overtime: California pays time and a half after 8 hours in a day and double time after 12 (California Department of Industrial Relations overtime FAQ, read 4 October 2026). Set the limits under Overtime rules to match your state or contract.

Does overtime carry over in a two-week pay period?

No. Federal overtime is worked out one workweek at a time, so the calculator splits each week separately: 45 hours then 35 hours is 5 hours of overtime even though the two weeks average 40.

What is the 7-minute rule?

Quarter-hour rounding. US regulations let an employer round times to the nearest 5 minutes, tenth of an hour or quarter hour as long as it averages out and does not short employees (29 CFR 785.48(b), read 4 October 2026). With quarter hours, 1 to 7 minutes round down and 8 to 14 round up. Choose Nearest 15 minutes to apply it to each shift.

How are night shifts handled?

If the clock-out time is earlier than the clock-in time, the shift is taken to end the next day: 22:00 to 06:00 is 8 hours. Type each shift on the day it starts.

Is my time sheet saved or sent anywhere?

No. Everything stays in your browser and is forgotten when you close the page. Use Copy the time sheet to paste it into an email or a document, or Print.

Is this calculator free?

Yes, completely free, with no sign-up.
