About Night Shift Hours Calculator

The premium rate is the base rate multiplied by the uplift, and total pay adds it to ordinary hours. Showing the premium as a share of total pay makes clear how much of the wage bill is discretionary. Night Shift consistently above about 15% of the wage bill is usually cheaper to solve with another hire than to keep paying at a premium.
