Reading the results
The headline figure is hours-and-minutes; the line beneath converts it to decimal hours, which is what payroll systems and timesheets expect. The conversion trips people up constantly: 7 hours 30 minutes is 7.50 hours, not 7.30 — minutes divide by 60. So 15 minutes = 0.25, 20 minutes = 0.33, 45 minutes = 0.75.
Break rules worth knowing
Whether your break is paid varies by law and employer. US federal law treats short breaks (5–20 min) as paid work time, while bona-fide meal periods of 30+ minutes can be unpaid. If your 30-minute lunch is unpaid, enter it here so the total matches your paycheck; if breaks are paid, leave the field at zero.
Overnight shifts
Enter times exactly as they happen — 22:00 to 06:00 correctly computes 8 hours. The calculator assumes any end time earlier than the start time crosses midnight.

Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time, then subtract unpaid breaks. 9:00 AM to 5:30 PM is 8.5 hours; minus a 30-minute lunch leaves 8 hours.
How do I convert minutes to decimal hours?
Divide minutes by 60. So 7 hours 45 minutes = 7 + 45÷60 = 7.75 decimal hours. Payroll systems use the decimal form.
Does this handle overnight shifts?
Yes — if the end time is earlier than the start time, the calculator assumes the shift crosses midnight. 11 PM to 7 AM correctly shows 8 hours.
Are lunch breaks paid or unpaid?
In the US, short breaks under 20 minutes are federally treated as paid time, while meal periods of 30+ minutes can be unpaid if you're fully relieved of duties. State rules vary — check yours.
Is the pay shown before or after tax?
Before tax — it's gross pay (hours × rate). For take-home pay after withholding, use our paycheck calculator for your state.
