Nurse Overtime Calculator – 12-Hr Shifts & 8/80 Rule

Overtime rules in healthcare are complex. This calculator supports the standard 40-hour week threshold, daily overtime triggers for 8 or 12-hour shifts, and the healthcare-specific 8/80 rule.

💡 Tips for This Calculator
  • The 8/80 rule is only available to hospitals and residential care facilities under section 7(j) of the FLSA.
  • California nurses have additional daily overtime rules — over 8 hours/day at 1.5x, over 12 at 2x.
  • Shift differentials generally must be included in the regular rate for overtime calculation under FLSA.

Frequently Asked Questions

What is the 8/80 overtime rule for nurses?+
The 8/80 rule (FLSA Section 7(j)) allows hospitals to pay overtime only for hours over 8 in a single day OR over 80 hours in a 14-day period, instead of the standard 40-hour weekly threshold.
Do shift differentials count toward my overtime base rate?+
Yes, under the FLSA. Your "regular rate of pay" for overtime purposes must include shift differentials. This means your overtime rate is calculated on the blended rate, not just your base hourly rate.
What is double time vs time-and-a-half?+
Time-and-a-half (1.5×) is the most common overtime rate. Double time (2× your regular rate) is required in California for hours over 12/day and on the 7th consecutive day. Use the multiplier toggle to switch between them.
