How to Use This Time Card Calculator

Using the calculator takes under a minute. Here is the exact sequence:

  1. Enter Time In — Type the time you started work for that day (e.g., 8:30 AM).
  2. Enter Time Out — Type the time you finished (e.g., 5:00 PM).
  3. Enter Break minutes — Add the total unpaid break time in minutes (e.g., 30 for a lunch break). Leave it at zero if you had no break.
  4. Repeat for each day — Fill in a row for every day you worked during the pay period.
  5. Select your pay period — Use the toggle to choose Weekly (1 week) or Biweekly (2 weeks).
  6. Read your results — The calculator displays Regular Hours, Overtime Hours, and Total Hours in both hh:mm and decimal. Enter an hourly rate to see Gross Pay.

If your shift crosses midnight — for example, 10:00 PM to 6:00 AM — enter the times normally. The calculator automatically detects overnight shifts and adds 24 hours to the calculation to give you an accurate total.

How to Calculate Hours Worked (Manually, Step by Step)

The calculator handles this automatically, but knowing the underlying math helps you verify results and catch errors on a paper timesheet.

Step 1: Subtract start time from end time. 8:30 AM to 5:00 PM = 8 hours 30 minutes.

Step 2: Deduct unpaid break time. 8 hours 30 minutes − 30 minutes = 8 hours worked.

Step 3: Convert minutes to decimal. Divide the remaining minutes by 60. 8 hours 0 minutes = 8.00 hours. If you had 8 hours 15 minutes, that becomes 8.25 hours (15 ÷ 60 = 0.25).

Step 4: Sum the week. Add your daily totals. A five-day week at 8.00 hours per day = 40.00 total hours.

Step 5: Split at 40 hours. Federal overtime rules in the US require time-and-a-half for hours beyond 40 in a workweek (under the Fair Labor Standards Act (FLSA)). Hours up to 40 are regular. Hours above 40 are overtime. Some states — California, for example — also apply daily overtime thresholds, so confirm the rules that apply to you.

Worked example:

Day Time In Time Out Break (min) Hours Worked
Monday 8:00 AM 5:00 PM 30 8.50
Tuesday 7:30 AM 5:30 PM 30 9.50
Wednesday 8:00 AM 5:00 PM 30 8.50
Thursday 8:00 AM 6:00 PM 30 9.50
Friday 8:00 AM 4:00 PM 30 7.50
Total 43.50 hours

Regular hours: 40.00. Overtime hours: 3.50. That math is straightforward when you only have five rows — it gets tedious fast across a two-week period. That is exactly where the calculator above saves time.

Weekly vs. Biweekly Time Cards: What Is the Difference?

A weekly pay period covers 7 consecutive days. A biweekly pay period covers 14 consecutive days — two full work weeks — and is the most common pay schedule in the United States, used by roughly 43% of private employers according to the Bureau of Labor Statistics.

The distinction matters for overtime. Under federal law, overtime is calculated per workweek, not per pay period. If you work biweekly, overtime is still assessed week by week — not across all 14 days combined. An employee who works 35 hours in week one and 45 hours in week two has 5 overtime hours, not zero.

This calculator supports both schedules. Select Weekly to track a single 7-day period, or switch to Biweekly to enter two full weeks of shifts and see totals broken down correctly. The Pay Period toggle at the top of the calculator controls which mode you are in.

Do You Need an App to Track Time Cards?

No. This calculator runs entirely in your browser. There is nothing to install, no updates to manage, and no account to create.

Open the page on a desktop, laptop, tablet, or phone — it works the same way on all of them. The layout adjusts to your screen size automatically. When you are done, use the Print, Email, or Download buttons to take the results with you. The only limitation to note: because no data is stored, refreshing the page clears your entries. Fill in your timesheet and export before closing the tab.

What If You Clock In and Out More Than Once a Day?

Some workers clock out for a lunch break and back in again, or leave mid-morning for an appointment and return. The current calculator is designed for a single in/out pair per day with one break deduction — the format that covers the majority of standard shifts.

If your schedule has a single unpaid lunch break, the Break field handles it. Enter 60 if your lunch is one hour, 30 if it is half an hour.

If you have multiple clock-ins and clock-outs in a single day, the workaround is to calculate each segment's duration manually (using the steps above), add them together, then enter a single effective "Time In" and "Time Out" that represents the combined total. It is an extra step, and it is not a perfect solution.

A dedicated multi-segment time card version — one that lets you log several in/out pairs per day — is planned for a future update. That version will eliminate the workaround entirely.

Frequently Asked Questions

Is this time card calculator really free?

Yes. There is no cost, no trial period, and no account required. Open the page and use it.

Does this calculator work in 24-hour (military) time format?

This calculator uses your device's own time picker, so whether you see AM/PM or 24-hour format depends on your phone or computer's system settings, not this page. If you want a 12-hour/24-hour toggle you control directly on the page, use our Work Hours Calculator instead.

Can I use this for a biweekly pay period?

Yes. Use the Pay Period toggle at the top of the calculator to switch between Weekly and Biweekly. In Biweekly mode, you can enter up to 14 days of shifts and the calculator tracks overtime week by week.

Is my data saved anywhere?

No. All calculations run locally in your browser. Nothing is sent to a server, and your entries are erased when you refresh or close the page. Export your results using the Print, Email, or Download buttons before leaving.

Can I print or email my time card?

Yes. The calculator includes Print, Email, and Download buttons so you can save or share your results in whatever format works for you.

How accurate is the overtime calculation?

The calculator applies the standard federal overtime rule — time-and-a-half for hours beyond 40 in a workweek — as defined under the Fair Labor Standards Act. State-level rules vary. California, for example, requires daily overtime for shifts beyond 8 hours. If your state or employment contract applies different thresholds, verify your totals against those specific rules or consult your payroll provider.
