40 hours before deductions.
$2.50 x 8 differential hours.
Gross pay divided by total paid hours.
Some payroll systems include shift differentials when calculating the regular rate for overtime. Use this as a gross estimate, then compare it with your employer policy and local rules.
Use this as a planning estimate. Taxes, fees, rates, account terms, provider policies, local rules, and timing can change real-world results.
Quick answer
Shift Differential Calculator calculates shift differential pay from base hourly rate, standard hours, differential hours, and differential premium. The visible formula is Gross pay = base rate x total hours + differential hours x differential premium.
Formula
Gross pay = base rate x total hours + differential hours x differential premiumSome payroll systems include differential pay when calculating overtime regular rate, so verify against local rules and employer policy.

Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
Enter only the additional premium, not the full hourly rate for the premium shift.
The blended rate helps compare total weekly pay across standard and premium shifts.
Differential pay may affect regular-rate overtime math. Use this result as a gross estimate, not a legal payroll determination.
Benchmarks
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
Often seen for modest evening or weekend differentials.
Can materially change weekly gross pay on recurring shifts.
Some employers state differentials as percentages instead of flat dollars per hour.

FAQ
Multiply differential hours by the extra premium paid per hour, then add that amount to base pay for all hours worked.
A shift differential is extra pay for certain shifts, such as nights, weekends, holidays, or hard-to-staff schedules.
It can. Some payroll rules include differential pay when calculating the regular rate for overtime, so check your policy or local rules.
No. Use it for planning and comparison. Real decisions can change after exact rates, balances, fees, taxes, account terms, timing, and personal details are verified.
Small changes in rates, payment timing, taxes, fees, balances, or income can materially change the result, so the assumptions need to stay visible.
Different tools may use different rounding, assumptions, default rates, methods, formulas, or input timing. Compare the visible method and inputs before relying on the output.
