Shift Pay Calculator
Calculate pay for a shift including a per-hour shift differential on top of the base rate.
What this calculator does
The Shift Pay Calculator estimates your result instantly from the values you enter, using standard business & finance formulas. Calculate pay for a shift including a per-hour shift differential on top of the base rate. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate for planning rather than financial advice.

About Shift Pay Calculator
The Shift Pay Calculator works out what a single shift is worth once a shift differential is added on top of your base hourly rate. Many roles that cover evenings, overnights, weekends, or holidays pay a little extra per hour, and this tool folds that premium into your effective rate so you can see the full picture before payday.
You supply three things: the hours worked on the shift, your base hourly rate, and the shift differential paid per hour. The calculator adds the differential to your base rate to get an effective hourly rate, then multiplies that by the hours worked to show total shift pay. Enter your hours, base rate, and differential in the fields, press Calculate, and read your effective rate and total shift pay in the result.
Formula & Mathematical Calculation
Shift Pay = Hours Worked × (Base Rate + Shift Differential) and Effective Rate = Base Rate + Shift Differential
Calculation Example
Suppose you work 40 hours on an overnight shift with a base rate of $20.00 per hour and a shift differential of $5.00 per hour. First add the differential to the base rate: $20.00 + $5.00 = $25.00 per hour effective rate. Then multiply by the hours worked: 40 × $25.00 = $1000.00 total shift pay.
Key Benefits
- Turns a per-hour shift differential into a single effective hourly rate you can actually compare.
- Shows total pay for a shift in one step so you can check it against your paycheck.
- Helps you weigh whether picking up a premium overnight or weekend shift is worth it.
- Uses only the three inputs you know off the top of your head: hours, base rate, and differential.
- Makes it easy to model different differential amounts before you commit to a schedule.
How to Use this Calculator
-
Enter hours worked
Type the number of hours in the shift into the hours field, for example 40. -
Enter your base rate
Type your standard hourly rate into the base rate field, for example 20. -
Enter the shift differential
Type the extra amount paid per hour for this shift into the differential field, for example 5. -
Calculate and read the result
Press Calculate to see your effective hourly rate and the total pay for the shift.
Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
- Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
- Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
- Amounts are unit-agnostic: results are returned in the same currency you enter.
What it does not cover
- Shift Pay Calculator produces estimates for education and planning, not a quote, offer or professional advice.
- Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
- Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For decisions with lasting financial impact, confirm the numbers with a qualified professional.
