Working over 40 hours this week?
This tool computes straight-time differential pay only. Under the FLSA (29 CFR 778.207), overtime must use the blended regular rate that includes your differential, so overtime is 1.5x the higher rate, not 1.5x base. Use the Overtime Pay Calculator for the hours-over-40 scenario.

ClockWage44 applies per-shift rate overrides on-device, so night, weekend, and holiday premiums land in your pay without manual math.
How shift differential pay works
Shift differential pay is premium pay for working shifts most people would rather avoid: nights, evenings, weekends, and holidays. Employers add it on top of the base hourly rate to staff those slots. You see it in healthcare, manufacturing, transportation, hospitality, and any operation that runs around the clock.
There are two common methods. A percentage premium scales with the base rate, so a $20/hr base with a 15% night premium gives an effective rate of $23/hr. A flat add-on tacks on a fixed dollar amount per hour, so that same $20/hr base with a $2/hr flat premium gives $22/hr. Either way, the differential applies only to the eligible (premium) hours.
How to calculate your shift differential
For the percentage method, the effective rate is base × (1 + percent/100). At $20/hr with a 15% night premium, that is $20 × 1.15 = $23/hr. The premium itself is $3/hr, so 36 eligible hours earn $108 in differential pay on top of base.
For the flat method, the effective rate is base + add-on. At $20/hr with a $2/hr add-on, the effective rate is $22/hr and the premium is $2/hr, so 36 eligible hours earn $72 in differential pay. That maps straight to the inputs above: set your base rate, choose percentage or flat, enter the differential amount, and enter your differential-eligible hours. Add regular-shift hours if you also worked non-premium time in the same period.
Shift differential and overtime (the blended rate)
When premium hours push you past 40 in a workweek, overtime cannot be figured on base pay alone. Under the FLSA (29 CFR 778.207), overtime uses the blended regular rate that includes the differential. If your base is $20/hr and the differential lifts your weighted average to $22/hr for the week, your overtime rate is 1.5 × $22 = $33/hr, not 1.5 × $20.
This calculator stays single-purpose and computes straight-time differential pay only. For the hours-over-40 math, run the numbers through the Overtime Pay Calculator. To turn the higher gross into take-home, the Net to Gross Paycheck Calculator helps, and the Decimal Hours Converter turns clock-in and clock-out times into the decimal hours these tools expect.
Typical differential rates by shift and industry
Premiums vary by employer and contract. Common ranges run roughly 10 to 15% for evening shifts, 15 to 25% for nights, 10 to 20% for weekends, and 20 to 50% for holidays. Flat amounts often land between $0.50 and $1.25 per hour for general hourly work.
Healthcare tends to pay more. Night differentials for nurses commonly run 15 to 20%, or roughly $1 to $10 per hour depending on the facility, region, and contract, with large academic medical centers at the higher end. Some employers also let premiums stack, so a shift that is both night and weekend can combine both rates. These figures are estimates only and not tax or legal advice. Confirm your exact rates with your employer or contract.
Frequently Asked Questions
Common questions about shift differential pay calculator
What is shift differential pay?
Shift differential pay is extra pay for working less desirable shifts: nights, evenings, weekends, or holidays. It sits on top of your base hourly rate to make a harder schedule worth taking.
How is shift differential pay calculated?
Two methods are common. With the percentage method, your effective rate equals base × (1 + percent/100). With the flat method, you add a fixed dollar amount per hour to the base rate. Multiply the per-hour premium by your eligible hours to get differential earnings.
What is a typical night shift differential percentage?
Common ranges run roughly 10 to 15% for evenings, 15 to 25% for nights, 10 to 20% for weekends, and 20 to 50% for holidays. Exact rates depend on your employer, region, and contract.
How much is night shift differential for nurses?
Night differentials for nurses commonly run 15 to 20%, or about $1 to $10 per hour, depending on the facility, region, and contract. Large academic medical centers tend to pay at the higher end.
Is shift differential pay the same as overtime?
No. Shift differential is a premium for the type of shift you work. Overtime is the higher rate, typically 1.5x, for hours past the legal threshold. Both can apply in the same workweek.
Does shift differential affect overtime pay?
Yes. Under the FLSA (29 CFR 778.207), overtime must be based on the blended regular rate that includes the differential. That means overtime is figured on base plus differential, not on base pay alone.
Is shift differential paid as a percentage or a flat dollar amount?
Both methods are used. Flat per-hour amounts are common for hourly workers, while percentages show up where pay scales vary or for salaried staff. This calculator handles either one.
Can you stack night and weekend differentials?
Often yes. A shift that qualifies for more than one premium can earn both. A 15% night premium plus a 20% weekend premium can combine into a 35% total premium, depending on employer policy.
