Frequently Asked Questions
How the calculator works, how the arithmetic is done, and what happens to your data.
Using the calculator
Do I need to press a Calculate button?
No. Totals update as you type. Every calculation runs in your browser the moment an input changes.
What time format should I enter?
The fields are native time inputs, so your browser shows a 12-hour or 24-hour clock according to your device settings and validates the entry for you. There is no AM/PM dropdown to get wrong.
What happens if I fill in only one punch for a day?
That day is skipped and a warning appears above the totals. A half-filled row is never silently counted as zero hours.
How do I copy the same shift across the week?
Fill in one day, then press Fill weekdays. The punches and break copy into every empty Monday-to-Friday row, leaving weekends alone.
Can I use it for a period that is not a full week?
Yes. Leave the days you did not work blank. Empty rows contribute nothing to the totals.
Hours, breaks & overtime
Why are hours shown as decimals?
Payroll systems use decimal hours, where 30 minutes is 0.5 and 45 minutes is 0.75. The hours-and-minutes figure is displayed next to the decimal total so you can check it at a glance.
How are overnight shifts handled?
When the clock-out is earlier than the clock-in, the shift is treated as crossing midnight and 24 hours are added before subtracting. A 10:00 PM to 6:00 AM shift counts as 8 hours.
What if I enter the same time for clock-in and clock-out?
It counts as zero, not twenty-four hours. Two identical punches are almost always an untouched row rather than a full-day shift.
How does punch rounding work?
Choose an increment under More options and each punch is rounded to the nearest 5, 6, 10, or 15 minutes before the difference is taken. Rounding punches rather than durations is standard payroll practice.
Is overtime measured over the whole pay period?
No. Overtime is measured against each seven-day week separately, which is what the law requires. On a biweekly card, a 50-hour week followed by a 20-hour week yields 10 hours of overtime even though the total is only 70.
Can an hour be counted as both daily and weekly overtime?
Never. Daily overtime and double time are assigned first, then only the remaining regular time is tested against the weekly threshold. The tiers always sum back to the hours actually worked.
Finding and building a time card calculator
Where can I find a time card calculator?
You are on one. This site is a free time card calculator that needs no account or download, with a version for each pay cycle: weekly on the home page, biweekly for 14-day periods, monthly and semi-monthly, one with lunch and break deduction, and dedicated overtime and California overtime calculators. Every version handles unpaid breaks, overnight shifts, split shifts and gross pay.
Do I need to download anything to use it?
No. It runs in any modern browser on phone, tablet or desktop and keeps working offline once the page has loaded. Choosing "Add to Home Screen" from your browser menu gives it its own icon and launches it full screen, so it behaves like an installed app without an app store account, download or adverts.
How do I make a time card calculator in Excel?
Put the clock-in time in B2, the clock-out in C2 and unpaid break minutes in D2, then use =(C2-B2+(C2<B2))*24-D2/60 for that day. The (C2<B2) term adds a day when the shift crosses midnight, multiplying by 24 converts Excel time into decimal hours, and D2/60 removes the break. Copy it down for each day, total the week with SUM, then split it using =MIN(total,40) for regular hours and =MAX(total-40,0) for overtime. Pay is regular x rate plus overtime x rate x 1.5. If you would rather skip the setup, the Excel button here exports the same figures as a real .xlsx workbook with the hours already as numbers.
Is there a time card calculator that adds up hours and minutes?
This one shows both at once. Each total appears in decimal hours for payroll — 8.50 — with the hours-and-minutes reading beside it, 8h 30m, so you can check the conversion at a glance without doing it yourself.
Privacy & exports
Is my timecard data sent to a server?
No. There is no backend that receives it. Every calculation happens in your browser and no timecard data leaves your device. Like most websites we do use analytics to count page visits, and the site may show advertising, both of which set cookies — but neither can see the times, rates or names you enter, because that information is never transmitted. The privacy policy covers this in full.
Where are my entries saved?
In your browser’s local storage, on your own device. They survive a refresh or closing the tab. The Clear button removes them.
How does the shareable link work?
Copy link encodes the whole timecard into the URL itself. Nothing is uploaded — the data travels inside the link, so anyone you send it to can open the same card. Bear that in mind before sharing a card with an employee name on it.
What export formats are available?
CSV for importing into payroll or a spreadsheet, PDF for a records copy, a print layout with the navigation and controls stripped out, and a shareable link.
Does it work offline?
Once a page has loaded, the calculator keeps working without a connection, because all the arithmetic runs locally.
Is it really free?
Yes. No account, no sign-up, no trial, and no upsell to paid time-tracking software.
Still stuck?
The step-by-step guide walks through the whole method by hand, including decimal conversion and overnight shifts. If you know which pay cycle you are on, jump straight to theweekly, biweekly, ormonthly calculator.
Everything here is general information to help you check a paycheck, not payroll or legal advice. Overtime rules vary by state and by industry — confirm the specifics that apply to you.
