The grid above applies the federal 40-hour weekly rule. If your question is more specific, each tool below is pre-configured for it:
Regular vs overtime pay under the federal 40-hour rule, split day by day.
Your 1.5× rate and overtime pay from two inputs — rate and OT hours.
Daily overtime after 8 hours, double time after 12, and the 7th-day rule — applied in the right order.
How to use it
- Enter your shifts. One row per day: clock-in, clock-out, and any unpaid break in minutes. Overnight shifts are detected automatically.
- Set your rate and rounding. Pick exact minutes or round each entry to 5 / 15 minutes or a tenth of an hour — the same policies timekeeping systems use.
- Read the split, not just the total. The panel separates regular, overtime, and double-time hours and prices each at 1×, 1.5×, and 2× your rate.
- Print or save. One click produces a clean pay-summary sheet for your records or a PDF.
How hours become pay
The calculator works the way payroll actually does: each day's worked time is measured in whole minutes (clock-out minus clock-in, minus unpaid breaks), the days are grouped into a workweek, and a ruleset decides which minutes pay 1×, 1.5×, or 2×. Under the default federal ruleset that's one rule — anything past 40 hours in the workweek is overtime. California adds daily thresholds and a 7th-day rule, which is exactly why it gets its own calculator.
Because everything is computed in minutes and only converted at the end, the decimal and h:mm figures always agree — 7:45 is 7.75 hours in both places, every time.
Frequently asked questions
- Is this work hours calculator free?
- Yes — every calculator on HourLedger is free, with no sign-up, no account, and no usage limit.
- Is my timesheet data saved or uploaded?
- Your entries are stored only in your own browser (localStorage) so they survive a page refresh on this device. Nothing is sent to a server, and Clear wipes them instantly.
- How do I convert minutes to decimal hours?
- Divide the minutes by 60: 15 minutes is 0.25 hours, 30 minutes is 0.5, 45 minutes is 0.75. The calculator shows every total in both formats simultaneously so you never have to convert by hand.
- Does it handle overnight shifts?
- Yes. If your clock-out time is earlier than your clock-in time (say 22:00 to 06:00), the calculator treats the shift as crossing midnight and counts the full span.
