Timecard GuruWhat Is a Time Card Calculator?
A time card calculator takes the times you actually worked and returns the total hours, usually in both hours-and-minutes and decimal form. Instead of doing the math by hand and risking a rounding slip, you enter your clock-in, clock-out, and breaks, and the tool handles the subtraction, midnight crossings, and addition. It is the fastest way to get a number you can drop straight onto a timesheet or into payroll.
What You Can Calculate
Pick the calculator that matches the number you are filling in. Each one is free, runs in the browser, and keeps a single job on the page. You can add up hours and minutes from several durations, or use the weekly timesheet calculator when each day has a clock-in and a clock-out.

- Adding several short tasks or side jobs into one daily or weekly total.
- Verifying your employer's math before you submit your time card.
How the Calculators Work
Every calculator runs entirely in your browser. You type your times, the result updates as you go, and nothing is uploaded. The weekly time card can be kept in this browser; the other calculators are not stored. There is no account to create and no limit on how many calculations you run, which makes it safe to check a number, change it, and check again before you finalize a timesheet.
Why Track Time as Decimal Hours
Payroll systems store time as a number so they can multiply it by an hourly rate directly. Decimal hours remove the step of converting clocks into math and stop the classic mistake of writing 30 minutes as 0.30 when it is really 0.50. Once your week is expressed as decimal hours, totals add up cleanly and audits stay simple.
Frequently Asked Questions
+What is a time card calculator?
A time card calculator turns raw clock-in and clock-out times, breaks, and shift lengths into a clean total of hours worked. Instead of adding minutes by hand, you enter your times and the tool returns the total as both hours and minutes and as decimal hours, which is the format most payroll systems use.
+How do I calculate hours worked from clock in and out?
Subtract your clock-in time from your clock-out time, add 24 hours if the shift crosses midnight, then subtract any unpaid break. For example, 9:00 AM to 5:00 PM with a 30-minute unpaid lunch is 7.5 hours. The Timesheet Calculator does this for every day of the week automatically.
+How do I subtract a lunch break from my work hours?
Find your total clock-in to clock-out span, then subtract the unpaid break length. A 9:00 AM to 5:30 PM day is 8.5 hours; removing a 30-minute lunch leaves 8.0 paid hours. Enter the break as an unpaid amount so your reported total matches what you are actually paid for.
+How do I add up a full week of work hours?
Total each day on its own, then sum the daily totals. Five 8-hour days equal 40 hours, and a mixed week such as 8 + 7.5 + 8 + 8.5 + 6.75 equals 38.75 hours. The Timesheet Calculator lets you enter all five days and shows the weekly total in both hours and minutes and decimal form.
+How do I convert time card hours to decimal?
Divide the minutes by 60 and add them to the whole hours. 7 hours 30 minutes is 7.50 decimal hours, because 30 ÷ 60 = 0.50. The other direction keeps the whole hours and multiplies the decimal by 60, so 8.15 hours is 8 h 9 min. Use the decimal hours calculator: https://timecardguru.com/decimal-hours-calculator
+How do I convert my timesheet to decimal hours?
Divide the minutes by 60 and add them to the whole hours. The formula is decimal hours = hours + minutes / 60, so 45 minutes becomes 0.75 and 1 hour 45 minutes becomes 1.75. The Decimal Hours Calculator applies this for any duration and rounds to the two decimal places payroll expects.
+Do these calculators save my data?
The weekly time card can keep the card in this browser's local storage so you can come back to the same week. Nothing is uploaded and there is no account. The other calculators are not saved.
+Is the time card calculator free to use?
Yes. All of the calculators are completely free, with no sign-up, no limits, and no ads on the tool pages. They are built to give you a fast, accurate total whenever you need to fill out a timesheet or check your pay.
+What is the difference between a time card and a timesheet?
A time card usually records a single employee's daily clock-in and clock-out for one shift, while a timesheet collects many entries, often a full week, into one summary. Timecard Guru gives you both views: a daily decimal or clock-in calculator and a weekly timesheet totaler.
+Are short rest breaks paid?
When the Fair Labor Standards Act applies, yes. 29 CFR 785.18 says rest periods of short duration, running from 5 minutes to about 20 minutes, must be counted as hours worked. That paid rest time may not be offset against other working time. A 10-minute rest break stays in the paid total. It is not a meal period.

+Is a 30-minute meal period unpaid?
A bona fide meal period is not hours worked. 29 CFR 785.19 says the employee must be completely relieved of duty for the purpose of eating a regular meal. Ordinarily 30 minutes or more is long enough. Coffee breaks and time for snacks are rest periods, not meal periods. If the employee has to perform any duties while eating, the time is hours worked. The employee does not have to be allowed to leave the premises if they are otherwise completely freed from duty.

+Can an employer round time clock punches?
29 CFR 785.48(b) describes rounding start and stop times to the nearest 5 minutes, the nearest tenth of an hour, or the nearest quarter of an hour. The practice is accepted for enforcement only when it averages out and does not, over a period of time, fail to pay for all the time actually worked. Rounding that always shortens the shift does not meet that test. The time clock rounding calculator at https://timecardguru.com/time-clock-rounding-calculator applies the quarter-hour practice and the nearest tenth of an hour.

+Is overtime calculated on the biweekly paycheck?
No. Each workweek stands alone. 29 CFR 778.104 says the Act does not permit averaging hours over two or more weeks, even when the employee is paid biweekly. Someone who works 30 hours one week and 50 the next is owed overtime for the hours past the weekly maximum in the second week, even though the two-week average is 40. 29 CFR 778.107 states the general standard: those overtime hours are paid at not less than 1.5 times the regular rate. Exemptions exist, and this is not a coverage decision.
