12-Hour Shift Pay Calculator for Nurses

Working three or four 12-hour shifts per week? This calculator is pre-configured for the most common nursing schedule, showing how differentials and overtime interact with your base pay.

💡 Tips for This Calculator
  • A 3×12 week = 36 hours, under the 40-hour threshold, so no OT unless your state has daily OT rules.
  • A 4×12 week = 48 hours. With standard 40hr threshold, 8 hours would be at overtime rate.
  • Many nurses choose 12-hour shifts for the compressed schedule and differential opportunities.

Frequently Asked Questions

Do 12-hour shifts trigger overtime?+

How do I maximize pay on 12-hour night shifts?+
Working 12-hour night shifts lets you earn your base rate plus night differential for all 12 hours. Add a weekend night and you stack both premiums. Our calculator shows you the combined effective rate instantly.
Are unpaid breaks deducted from 12-hour shift pay?+
