Work Hours Calculator

How to Use Hours Calculator

1. For each weekday row, enter the start time and end time, plus any break minutes.
2. If a shift crosses midnight (e.g., 10 PM to 6 AM), simply enter the real clock times — the tool adds 24 hours automatically.
3. Optionally enter an hourly rate to see total pay. Click Add Day for extra rows or remove unused ones.
4. The live result shows total hours and minutes, decimal hours (for invoices), and total pay if a rate is set.

Frequently Asked Questions

How do I calculate work hours that go past midnight?

Enter the actual start and end times. If the end time is earlier than the start, the tool interprets it as the next day and adds 24 hours automatically, giving you the correct total.

Why does the calculator show decimal hours?

Decimal hours are the standard for payroll because they multiply directly with an hourly rate. 7 hours 30 minutes equals 7.5 hours; the tool converts this for you.

Can I use this for a bi‑weekly or monthly timesheet?

Yes, add as many day rows as you need. The tool sums all rows into total hours and pay, regardless of how many days you track.

Is Hours Calculator free and private?

Yes — it is 100% free, needs no sign-up, and everything runs in your browser; your data never leaves your device.
