NIGHT AND EVENING PAY
Shift Differential Calculator
Calculate flat or percentage night, evening and weekend shift differential pay with an itemized gross-pay estimate.
THE PROBLEM THIS SOLVES
Your paycheck lists a shift premium, but you cannot tell whether the eligible hours or rate are correct.
Enter your base rate, paid hours and the differential from your employer policy. The result separates base pay from the extra amount so you can check each line.
Estimate only. Confirm the rates, eligible hours and rules that apply to your employer and location.
Get a result you can actually check.
Count eligible hours
Enter only the hours that fall under the written differential rule.
Compare each line
Check the calculated premium against the matching line on your pay stub.
See the calculation in context.
At a $28 base rate, a flat $3.25 differential for 32 eligible hours adds $104. A 10 percent differential would add $89.60 for the same hours.
Before you rely on the result
Is night shift differential required?
Federal law generally does not require extra pay simply because work occurs at night. Employer policy, an agreement or another applicable rule may provide it.
Can a weekend premium be added too?
Sometimes. Confirm whether your employer stacks premiums or pays only the higher one.
Does differential affect overtime?
Some differentials may be included in the regular rate used for overtime. Use the result as an estimate and check the applicable policy and rules.
