Pay Differential Calculator

Estimate the extra pay created by a shift, night, weekend or geographic differential when an employer defines the premium as a percentage, a flat amount per hour, or both.

Enter the premium exactly as your employer defines it. A geographic differential is not universal: some employers use a percentage, some a fixed amount, and some use a separate salary table.

What counts as a pay differential?

A differential is extra compensation tied to conditions such as night work, weekends, a hard-to-staff shift, location or another employer-defined factor. This calculator does not assume a universal rate; it simply applies the rate you enter.

Percentage vs flat differential

A 10% differential on a $20 hourly base adds $2 per eligible hour. A $3 flat differential adds $3 per eligible hour. If your policy combines both, this tool can estimate them together.
