Is the overtime rule the same everywhere?

No — this applies only the federal FLSA standard (over 40 hours in a week). Some states require daily overtime thresholds, and rules outside the US vary substantially — check your own jurisdiction.

Can I use this for a pay period longer than one week?

Not directly — FLSA overtime is calculated per workweek, so this tool models a single week at a time.

What if I don't want to see pay, just hours?

Leave the hourly rate field blank or at 0 — only the hours readout will be meaningful.

How to use it

Enter clock-in and clock-out times for each day worked, plus any unpaid break minutes.
Optionally enter an hourly rate to see total pay.
Read total hours, regular vs. overtime hours, and (if a rate was entered) total pay.

Formula

Daily hours = (clock-out − clock-in) − break minutes, in hours (an overnight shift where clock-out is earlier than clock-in adds 24 hours). Regular hours = min(week total, 40). Overtime hours = max(0, week total − 40). Overtime pay = overtime hours × rate × 1.5.

Worked example

5 days at 8 hours (0 break) = 40 regular hours, no overtime. Add a 6th day of 4 hours: 44 total hours = 40 regular + 4 overtime at 1.5× rate.

Recommendations

• This models only the federal FLSA standard (over 40 hours/week) — some US states (California, for example) require daily overtime after 8 hours, which this tool doesn't apply.
• A clock-out time earlier than clock-in is treated as an overnight shift crossing midnight, not an error.
• Leave the hourly rate blank if you just want the hours total — pay figures only appear once a rate is entered.

Frequently asked questions

Yes — if clock-out is earlier than clock-in, it's treated as a shift that crosses midnight, adding 24 hours before subtracting the break.
