Free Work Hours Calculator for Accurate Time Tracking

A work hours calculator helps you quickly calculate the amount of time worked between a start time and an end time. Instead of manually counting hours, subtracting lunch breaks, converting minutes into decimals, or estimating overtime by hand, this tool gives you a simple breakdown in seconds.

This calculator is useful for employees checking a shift, freelancers estimating billable hours, small business owners reviewing employee time, and anyone who needs a fast hours worked calculator with break deductions and pay estimates. You can use it as a daily shift calculator, a simple time card calculator, or a work hours and pay calculator for estimating earnings before payday.

How to Use the Work Hours Calculator

Follow these simple steps to calculate your actual hours worked and estimated pay.

1

Enter Your Start and End Time

Add the time your shift started and the time your shift ended. The calculator also supports overnight shifts that pass midnight.

2

Subtract Unpaid Breaks

Enter lunch breaks or unpaid rest breaks in minutes. The calculator subtracts this from the total shift length to show actual worked hours.

3

Add Your Hourly Rate

Enter your hourly wage to estimate regular pay, overtime pay, and total earnings for the shift.

4

Set Overtime Rules

Choose the overtime threshold and multiplier that apply to your situation, such as overtime after 8 hours at 1.5x pay.

Work Hours Formula

The basic formula for calculating work hours is:

Hours Worked = End Time – Start Time – Unpaid Break Time

If your shift starts at 9:00 AM and ends at 5:30 PM, your total shift length is 8.5 hours. If you took a 30-minute unpaid lunch break, your actual hours worked would be 8.0 hours.

Example Calculation

Start time: 9:00 AM

End time: 5:30 PM

Unpaid break: 30 minutes

Total shift: 8.5 hours

Hours worked: 8.0 hours

Common Ways to Use This Calculator

  • Calculate hours worked for a single shift.
  • Subtract unpaid lunch breaks from total shift time.
  • Estimate hourly pay before payday.
  • Calculate overtime after a daily threshold.
  • Check overnight shifts that pass midnight.
  • Convert clock-in and clock-out times into decimal hours.
  • Review time card entries before submitting payroll.

Tips for Calculating Work Hours Correctly

For the most accurate results, always enter your actual clock-in and clock-out times. If your workplace deducts unpaid lunch breaks automatically, make sure to include that break time in the calculator. If your break is paid, leave the unpaid break field at zero.

Overtime rules can vary depending on your employer, location, employment type, and work agreement. Some jobs calculate overtime after 8 hours in a day, while others calculate overtime after 40 hours in a week. This calculator lets you adjust the overtime threshold so you can estimate pay based on the rules that apply to your situation.

Work Hours Calculator FAQs

Answers to common questions about calculating hours worked, breaks, overtime, and pay.

How do I calculate hours worked?

To calculate hours worked, subtract your start time from your end time, then subtract any unpaid break time. For example, 9:00 AM to 5:30 PM is 8.5 hours. If you take a 30-minute unpaid break, your paid work time is 8.0 hours.

Does this calculator subtract lunch breaks?

Yes. Enter your unpaid lunch break or unpaid rest break in minutes, and the calculator will subtract it from your total shift length to calculate actual hours worked.

Can I calculate overtime hours?

Yes. Enter an overtime threshold, such as 8 hours, and an overtime multiplier, such as 1.5. The calculator will separate regular hours from overtime hours and estimate both regular pay and overtime pay.

Does this work for overnight shifts?

Yes. If your end time is earlier than your start time, the calculator treats the shift as passing midnight and calculates the correct shift length.

Is this the same as a timesheet calculator?

This page calculates a single shift. If you need to calculate multiple days, weekly totals, or a full pay period, use the Timesheet Calculator instead.

Can freelancers use this calculator?

Yes. Freelancers, consultants, contractors, and service providers can use this calculator to estimate billable hours and hourly project earnings.

Is the estimated pay exact?

The pay result is an estimate based on the hourly rate, break time, overtime threshold, and overtime multiplier you enter. It does not include taxes, deductions, bonuses, holiday pay, or employer-specific payroll rules.

Need to Calculate a Full Week?

Use the Timesheet Calculator next to calculate daily hours, weekly totals, overtime, and estimated pay across multiple workdays.
