Assumptions worth checking
Using This Calculator
Scenario: estimate a cross-midnight premium split
Use this page when a late shift crosses midnight and you need to separate standard paid hours from hours that fall inside the night premium window.
- Result factors: shift start, shift end, unpaid break minutes, base rate, night premium, and the 10 PM to 6 AM window.
- Example: a 9 PM to 5:30 AM shift can include standard evening time, night-window time, and deducted break time in the same summary.
Limits and related planning tools
Night differential policies vary. Confirm how breaks, overtime stacking, and premium windows are defined before using the estimate in payroll review.
- Use Shift Differential Pay Calculator when the premium rule is the main planning question.
- Use Overtime Hours Calculator when the same week may also cross a regular-hours threshold.
Example handoff: premium-window note
When sharing the result, include the shift span, deducted break minutes, night-window hours, base rate, and premium rate so the assumption is visible.
- Related planning tools: Shift Hours Calculator for base paid time and Overtime Hours Calculator for weekly threshold checks.

Calculator questions
What people usually check next
What does the night-hours result represent?
It estimates the paid portion of the shift that overlaps the night window after unpaid breaks are deducted proportionally.
Can this handle my employer-specific night window?
Not by itself. This page uses the current calculator window and should be checked against employer policy when the official window or differential rule is different.
What should I use with the night-shift result?
Use Shift Hours Calculator for a base paid-hours check, then use Overtime Hours Calculator if the same shifts may also create weekly overtime.
