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
- 40 working hours per week
- 52 working weeks per year
- 12 monthly pay periods per year
- 26 biweekly pay periods per year
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 yearRaise formulas
Known raise percentage
New pay = Current pay × (1 + Raise percentage ÷ 100)Known target pay
Raise percentage = (Target pay − Current pay) ÷ Current pay × 100Known raise amount
New pay = Current pay + Raise amountWhat 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.
