How This Time Card Calculator Works

Use this time card calculator to track clock in and clock out times for each day, subtract unpaid breaks, and calculate total work hours automatically. The tool shows both standard time and decimal hours so you can use the results for payroll, employee hours, and billing.

// Time card formula
Worked Hours = (Clock Out - Clock In - Break Minutes) ÷ 60
// Example: 8:00 to 17:00 with a 60 minute lunch
1. Shift length: 9.00 hours
2. Subtract the unpaid lunch: 9.00 − 1.00 = 8.00
3. Decimal hours worked: 8.00

How to Use the Time Card Calculator

A simple workflow for payroll, timesheets, and weekly hour tracking.

1. Enter clock in and clock out times

Enter each day's clock times. 12-hour and 24-hour times both work.

2. Add lunch and other breaks

Enter unpaid break minutes for that day. 30, 45, and 60 minutes are the most common lunch lengths.

3. Check overtime, then copy or export

Hours over 40 in the week are overtime. Confirm the total, then copy it or download the CSV.

Common Shifts and Hours Worked

Net hours after breaks — the same figure a time card calculator reports for each day.

Time Card Calculator with Lunch Breaks

An unpaid lunch is not paid time. Subtract it from the shift. A 30-minute lunch removes 0.50 hours, a 45-minute lunch removes 0.75, and a 60-minute lunch removes 1.00.

Example: 8:00 AM to 5:00 PM is a 9.00 hour shift. A 30-minute unpaid lunch leaves 8.50 hours. A 60-minute unpaid lunch leaves 8.00. If the lunch is paid, leave the break field at 0 so those minutes stay in the total.

Overtime on a Time Card

A common US rule treats hours over 40 in a workweek as overtime, often paid at 1.5 times the regular rate. Some states also count hours over a daily limit, such as 8 hours in a day. This page is not legal advice. Use the rule that applies where the work is done.

Example: a week that totals 43.50 decimal hours is 40.00 regular hours and 3.50 overtime hours. Multiply only the 3.50 by the overtime rate when you estimate pay.

Overnight and Second-Shift Time Cards

An overnight shift ends on the next calendar day. If clock out is earlier than clock in, the calculator treats the shift as crossing midnight. 10:00 PM to 6:00 AM is 8.00 hours before breaks. With a 30-minute unpaid break, the net is 7.50 hours.

This is the usual pattern for restaurants, security, and hospital shifts that run through the night. Enter the times as shown on the time clock. You do not need to add 24 hours yourself.

Converting Time Card Hours to Decimal

Payroll systems multiply decimal hours, not clock time. Divide the minutes by 60. 15 minutes is 0.25, 30 minutes is 0.50, and 45 minutes is 0.75. An 8 hour 30 minute day is 8.50 decimal hours.

Look up a single minute on the minutes to decimal chart. Convert one custom value with the time to decimal converter, or turn a decimal total back into clock time with the decimal to time converter. For a spreadsheet, see how to convert time to decimal in Excel.
