Gross shift pay

$880.00

Adjusted hourly rate
$22.00
Extra differential pay
$80.00

How this is calculated

  1. $20.00 + $2.00 = $22.00 per eligible hour.
  2. 40 hours × $22.00 = $880.00 gross shift pay.
  3. 40 hours × $2.00 = $80.00 extra differential pay.

Amounts are displayed to the nearest cent. Calculations use unrounded values.

How it works

Some employers pay an additional hourly amount for nights, weekends, holidays, or less desirable shifts. This calculator adds that differential to your base rate.

Example

If your base rate is $20 per hour, your shift differential is $2 per hour, and you work 40 hours, your adjusted hourly rate is $22 and your total pay is $880.

Separate hours with and without a premium

Suppose you work 24 daytime hours at $20 and 16 night hours with a $2 differential. Enter only the 16 night hours here: the result is $352, including $32 of extra differential pay. The other 24 hours add $480, making total straight-time pay $832.

Entering all 40 hours here would apply the premium to every hour and produce $880, overstating this example by $48. Check whether your policy applies the differential to the whole shift, specific hours, or another category.

Convert a percentage to dollars first

For a 10% differential on a $24 base rate, calculate $24 × 0.10 = $2.40 and enter 2.40 as the differential. The adjusted rate is $26.40. Entering 10 would add ten dollars per hour instead.

Shift differentials can also affect the regular rate used for overtime. If you worked mixed rates or overtime hours, this simple addition is not a complete overtime calculation. Use payroll's regular-rate breakdown when checking that part of your check.
