Shift roster
Overtime calculator with shift differential (blended regular rate)
A common underpayment story: OT paid on base rate while night differentials were ignored in the regular rate. This page estimates a blended regular rate from straight-time earnings and hours, then applies your OT multiplier.

When to use
Checking a stub that feels short; modeling night-heavy weeks.
When not to
Simple OT without differentials → nurse overtime.
Assumptions: Simplified weekly model; exact FLSA inclusions are richer than this teaching estimate.
Worked examples
Input
Straight-time $1,760 40 hrs 8 OT @ 1.5×
Output
Regular rate $44 OT ≈ $528
Input
Same OT on base-only $40 × 1.5 × 8
Output
$480 — short vs blended
Illustrates why blending matters.
Common traps
- Not every dollar in a paycheck belongs in the regular rate.
- 8/80 hospital plans change the period — this page is a weekly teaching estimate.
- If your stub already shows OT correctly, don't 'fix' it with a blog formula.
