What is a free time card calculator?

A free time card calculator adds up the hours you worked from your clock-in and clock-out times. Instead of subtracting times by hand and converting minutes, you enter each shift and any breaks, and the calculator shows your daily hours, your weekly total and, if you add an hourly rate, an estimate of your gross pay.

It is built for the situations that make manual math error-prone: unpaid lunches, split shifts, shifts that cross midnight and totals that need to be in decimal hours for payroll. You can print the result or download it as a spreadsheet file, with no signup.

How to use this calculator

1. Pick the week you want to calculate and choose Monday or Sunday as the first day.
2. Enter the clock-in and clock-out time for each day you worked. Use Quick Fill to fill Monday to Friday in one step.
3. Add breaks as paid or unpaid, using start and end times or just the number of minutes.
4. Add another shift to any day if you worked a split schedule.
5. Optionally enter an hourly rate, your name and your company.
6. Press Calculate Time Card, then copy, print or download the timesheet.

How to calculate work hours

The calculation for each shift follows the same steps:

• Shift time = clock-out − clock-in
• Paid time = shift time − unpaid breaks
• Daily hours = sum of paid time for all shifts that day
• Weekly hours = sum of the seven daily totals

To work out the time between two clock times by hand, subtract the start from the end, borrowing an hour when the minutes don’t line up. From 8:45 AM to 4:20 PM, for example, is 7 hours and 35 minutes, which is 7.58 in decimal hours. Everything in this calculator is done in whole minutes and only converted at the end, so adding many shifts never introduces rounding errors.

Time card examples

Example 1: a regular day. You clock in at 9:00 AM and out at 5:00 PM with a one-hour unpaid lunch. The shift is 8 hours, and paid time is 7 hours.

Example 2: a full week. You work Monday to Friday from 8:30 AM to 5:00 PM with a 30-minute unpaid break. Each shift is 8 hours 30 minutes, paid time is 8 hours a day, and the week comes to 40 hours.

Example 3: an overnight shift. You clock in at 10:00 PM and out at 6:30 AM with a 30-minute unpaid break. The shift is 8 hours 30 minutes, and paid time is 8 hours.

Example 4: a split shift. You work 7:00 AM to 11:30 AM and again from 1:00 PM to 5:15 PM. That is 4 hours 30 minutes plus 4 hours 15 minutes, for 8 hours 45 minutes, or 8.75 hours.

Example 5: estimated earnings. You are paid $18.50 an hour and your week comes to 37.5 hours. Gross pay is 37.5 × $18.50, which is $693.75 before taxes and deductions. If your week goes past 40 hours, use the Overtime Calculator to see the overtime pay.

Overnight shifts

If you work across midnight, enter the times exactly as they happened. A shift from 10:00 PM to 6:00 AM is 8 hours. When the clock-out time is earlier than the clock-in time, the calculator treats the shift as ending the next day and labels it, so you can see how it was read. The hours are counted on the day the shift started, which matches how most timesheets are kept.

Minutes to decimal hours chart

Payroll often uses decimal hours, where a minute is a fraction of an hour. To convert, divide the minutes by 60. To convert a full time such as 7 hours 45 minutes, keep the hours and convert only the minutes: 7 + 0.75 = 7.75. Another example is 6 hours 10 minutes, which is 6.17, and 8 hours 20 minutes, which is 8.33. This chart rounds to two decimal places:

12-hour to 24-hour time chart

Some employers and time clocks use 24-hour (military) time. For AM hours the number stays the same, except that 12:00 AM is 00:00. For PM hours, add 12, except that 12:00 PM stays 12:00. So 5:30 PM is 17:30. You can switch the calculator between 12-hour and 24-hour display, and your entered times are not changed when you do.

Paid and unpaid breaks

Federal law does not require employers to give adults meal or rest breaks, but when they do, the Fair Labor Standards Act sets rules for whether the time is paid. Short rest breaks, usually 5 to 20 minutes, are generally counted as paid working time. A meal period of at least 30 minutes can be unpaid when you are fully relieved of duty and free to leave your post. If you are expected to keep working through lunch, that time is generally work time and should be paid.

Many states have their own break laws, and some require meal or rest breaks. Company policy and union agreements can also be more generous. Use the paid or unpaid setting that matches how your employer actually pays you. In this calculator, an unpaid break is subtracted from your shift, and a paid break is recorded but stays in your paid hours.

Rounding time on time cards

Some workplaces round clock punches to the nearest 5 minutes, the nearest tenth of an hour or the nearest quarter hour. A common version is the 7-minute rule, where punches within 7 minutes after a quarter hour round down and punches from 8 minutes on round up. Federal rules allow rounding only when it is neutral: over time it should average out and not cut employees’ pay. This calculator does not round anything, so you can compare its exact total with the hours on your pay stub and spot a pattern if you think you are being shorted.

Split shifts and multiple shifts

A split shift is a workday divided into two or more parts with an unpaid gap in between, such as a morning and an evening shift. Enter each part as its own shift on the same day. The calculator adds them together, shows each one in the breakdown, and warns you if two shifts overlap. The gap between shifts is not counted as paid time unless you enter it as part of a shift.

Weekly, biweekly and monthly timesheets

Employers pay on different schedules: weekly (52 paychecks a year), biweekly (26), semi-monthly (24) or monthly (12). Your timesheet covers a pay period, but federal overtime is calculated by the workweek, a fixed, recurring period of 168 hours. For a biweekly or monthly period, calculate one week at a time, then add the totals for your pay stub. Keeping the weeks separate also makes it easy to see which week crossed 40 hours.

How long to keep time records

Under federal rules, employers generally have to keep payroll records for at least 3 years and basic records such as time cards for at least 2 years. Some states require longer. As an employee, it is worth keeping your own copy of your hours, since a CSV file or a printout takes seconds to save and can settle a question about a past paycheck.

Who uses a time card calculator?

• Hourly employees check that their paycheck matches the hours they worked.
• Small-business owners and managers total weekly hours without paying for a time-tracking system.
• Contractors and freelancers document time for clients and invoices.
• Construction and trade crews track daily hours across job sites and shifts.
• Caregivers, drivers and shift workers handle irregular and overnight schedules.
• Payroll assistants verify hours before entering them in payroll software.

Common time card mistakes

• Mixing up AM and PM. This can add or remove 12 hours at once.
• Forgetting the unpaid lunch. A 30-minute break left in adds 2.5 hours to a five-day week.
• Entering an overnight shift as if it ended the same day. This produces a negative or zero total.
• Rounding each shift before adding them. Small errors pile up. Add exact times first, then round the total if needed.
• Counting minutes as decimals. 7 hours 30 minutes is 7.5 hours, not 7.30.
• Treating a missing entry as time worked. Leave unworked days empty.

Tips for accurate timekeeping

• Write down your clock-in, clock-out and breaks the same day, while you remember them.
• Note whether each break was paid or unpaid, since it changes the total.
• Compare your calculated hours with your pay stub every pay period.
• Save a copy of each timesheet so you have a record if there is a dispute.
• If something doesn’t match, tell your supervisor or payroll contact early, in writing.

Time card, timesheet and time clock

A time card records when you clock in and out. A timesheet is usually a weekly or project-based record of hours worked. A time clock is the device or software that captures the punches. The words are often used interchangeably, and this calculator works for all of them: enter the punches, and it turns them into daily and weekly hours.

Limitations

This free time card calculator totals hours and gives a basic earnings estimate at a single hourly rate. It does not apply overtime, rounding rules, taxes or deductions. If you worked more than 40 hours, use the Overtime Calculator to estimate time-and-a-half pay. Your employer’s official records and payroll system are what count for your actual paycheck, and this page is not legal or payroll advice.
