How to use this result
Some employers pay the night differential for the entire shift; others apply it only inside a time window. Enter qualifying hours separately so a partial-night shift does not receive a full-shift premium by accident.
A percentage is based on the base rate you enter. A 10% differential on $30 is $3 per eligible hour, while a $4 differential stays $4 when the base rate changes.
The formula
Worked example
Using the example inputs loaded above:

Gross pay with night differential.
Common questions
Is a 10% differential the same as $10 per hour?
No. At $30 base pay, 10% adds $3 per hour. Choose the correct differential type before entering the amount.
Does this include overtime?
It is a straight-time comparison. Use overtime with differentials to price a workweek that has overtime.
