What is a work hours calculator?

A work hours calculator computes net hours from clock-in and clock-out times, subtracts unpaid breaks, and outputs decimal hours for timesheets and payroll estimates.

Enter a start time, end time, and unpaid break duration to get net hours worked and decimal hours (for example, 7 hours 30 minutes = 7.5). Overnight shifts are handled automatically when the end time is earlier than the start on the clock.

Use decimal hours when exporting totals to time-tracking apps, invoicing clients, or comparing against weekly rollups. This tool runs entirely in your browser—shift times are not uploaded to servers.

Use decimal hours (7.5, not 7:30) when exporting totals to time-tracking apps.

How to use Work Hours Calculator — Net Hours, Breaks & Decimal Time

  1. Enter your start time

    Type clock-in in HH:MM (AM/PM or 24-hour). Overnight shifts use actual times—midnight crossing is detected automatically.

  2. Enter your end time

    Type clock-out. If end is earlier than start (e.g., 10 PM to 6 AM), 24 hours is added to the end time before subtracting.

  3. Enter unpaid break minutes

    Subtract lunch or other unpaid breaks from gross duration. Paid breaks are not entered here.

  4. Copy decimal hours

    Use the decimal output (e.g., 7.5) when logging hours in spreadsheets or time apps.

Common mistakes to avoid

Using 7:30 instead of 7.5 decimal hours

7 hours 30 minutes = 7.5 decimal hours, not 7.30.

Deducting paid breaks

Only enter unpaid break minutes; paid rest periods count as worked time.

Frequently Asked Questions

How do I handle an overnight shift?

Enter start and end normally. When end is earlier than start, the tool adds 24 hours to the end time before computing net hours.

What is the decimal hours formula?

Decimal hours = whole hours + (minutes ÷ 60). Example: 7h 30m = 7.5.

Should I enter paid or unpaid breaks?

Enter only unpaid breaks (typical meal breaks). Paid breaks stay in gross time.

Is this the same as a weekly timesheet?

This tool focuses on one shift or day. For multi-day totals, use the weekly work hours calculator with decimal-hour inputs per day.

Are my times stored on a server?

No. All math runs in your browser; nothing is uploaded during normal use.

Can I use decimal hours for payroll?

Decimal hours match many timesheet systems, but employer rounding and break policies may differ—verify with your payroll rules.

Privacy, accuracy, and trust

Privacy

Shift times and break minutes are processed in your browser—they are not uploaded to EverydayTools servers.

Accuracy

Net hours follow the times you enter; overnight detection adds 24 hours when end precedes start on the clock.

Hour totals are estimates from the times you enter. Employer rounding and break policies may differ—keep your original shift records.
