Shift differential calculator
Differentials apply to the hours inside the window — not your whole shift. Enter your rate, your differential, and how many hours land in the window; get your effective rate and what the shift really pays.
Overnight shifts:a 6 PM–6 AM shift with a 7 PM window start has 11 hours in the window, not 12. Count only the in-window hours — that's what your payroll does (or should).
