Night shift differential calculator
Overnight hours usually pay more — sometimes a lot more in hospitals. Enter base rate, night premium (% or $/hr), and night hours; see premium dollars and what those hours effectively pay.

When to use
Weighing nights vs days on the same unit; checking an offer that quotes night premiums.
When not to
For a full week with OT and mixed differentials, use paycheck with differentials or nurse pay.
Assumptions: You define which hours count as night; the tool does not look up your hospital's clock window.

Common traps
- Partial nights need hour splits — don't apply night % to the whole 12 if policy doesn't.
- Some night premiums exclude OT hours.
- Ask whether the % applies to charge or only staff base.
