How Much Is Night Shift Differential Really Worth?

Updated August 2025 · Based on verified union contract data

Night shift differential is extra pay you earn for working overnight hours (typically 11pm–7am). But how much does it actually add to your paycheck after taxes?

Typical night differential rates

Based on union contracts at California hospitals, here's what workers actually receive:

HospitalNight DifferentialExtra per 2-week check (72hrs)
Dominican Hospital$3.25/hr+$234 gross
St. Mary's Medical Center$3.50/hr+$252 gross
Mercy Medical Center Redding$3.25/hr+$234 gross
Woodland Healthcare$2.45/hr+$176 gross
Mercy Hospital of Bakersfield10%Varies by base rate
St Bernardine Medical Center15%Varies by base rate

What does $3.25/hr night diff actually mean for your paycheck?

Let's say you're a Respiratory Therapist making $55/hr base, working 3x 12-hour night shifts per week:

PeriodBase OnlyWith Night Diff ($3.25)Difference
Hourly$55.00$58.25+$3.25
Biweekly gross$3,960$4,194+$234
Monthly gross$8,580$9,087+$507
Annual gross$102,960$109,044+$6,084
After taxes: That $6,084/year gross becomes roughly $3,900–$4,200 in actual take-home pay (after federal, CA state, SS, and Medicare). That's an extra $150–$162 per paycheck net.

Percentage-based differentials

Some hospitals use percentage-based night differentials instead of flat dollar amounts:

Percentage differentials are more valuable for higher-paid workers since they scale with your base rate.
