Calculation methodology

How SalaryKit calculates your pay raise

SalaryKit annualizes the pay amount you enter, applies the selected raise, and converts the result into each supported pay period. The calculations run in your browser and use the assumptions shown below.

Default work assumptions

Hours per week and weeks per year can be changed in the calculator. Monthly pay always uses 12 periods; biweekly pay uses half of the selected weeks per year.

Pay-period conversions

Annual pay = Monthly pay × 12Annual pay = Biweekly pay × (Weeks per year ÷ 2)Annual pay = Weekly pay × Weeks per yearAnnual pay = Hourly pay × Hours per week × Weeks per year

Raise formulas

Known raise percentage

New pay = Current pay × (1 + Raise percentage ÷ 100)

Known target pay

Raise percentage = (Target pay − Current pay) ÷ Current pay × 100

Known raise amount

New pay = Current pay + Raise amount

What the result does not include

Results show gross pay before taxes, payroll deductions, benefits, bonuses, overtime premiums, unpaid leave, and employer costs. They are general estimates, not financial, tax, legal, or employment advice.

Testing and corrections

We test annual, monthly, biweekly, weekly, and hourly conversions against fixed examples. We also test percentage raises, target-pay calculations, fixed raise amounts, custom work assumptions, and currency formatting before deployment.

If you find a reproducible issue, contact SalaryKit with the pay period, calculation mode, and assumptions you used.
