Pay Raise Calculator
Convert a percentage or new base-pay amount across hourly, paycheck, monthly, and annual views while separating bonuses.
Content updated August 3, 2026
Gross straight-time comparison only. Biweekly means 26 periods and semimonthly means 24. Taxes, deductions, benefits, commissions, equity, overtime, unpaid time, leave rules, and changing weekly hours are excluded; use the separate bonus inputs to avoid treating a one-time bonus as base pay.
A raise can look different when quoted per hour, paycheck, month, or year. This calculator normalizes one base-pay change across those periods and keeps annual bonuses separate so a one-time payment is not mistaken for a lasting change in base pay.
Choose a percentage change or enter the replacement base-pay amount for the selected period. Negative percentage changes can model a pay cut, while the hours and paid-weeks inputs make the hourly and annual views explicit.
The Pay Raise formula
New period pay = current × (1 + change %) or entered new pay; annual base = period pay × periods/year; annual total = annual base + annual bonusHourly periods/year = hours/week × paid weeks/year · weekly = 52 · biweekly = 26 · semimonthly = 24 · monthly = 12 · annual = 1.
Worked example
At $25 per hour, 40 hours per week, and 52 paid weeks, current annual base pay is $52,000. A 10% raise produces $27.50 per hour, $57,200 annual base pay, and a $5,200 annual base increase before bonus changes.
Assumptions, rounding, and limitations
Assumptions
- All money values use the selected currency and represent gross pay before taxes and deductions.
- Hourly annualization uses the entered typical weekly hours and paid weeks; other selected pay periods use fixed counts of 52, 26, 24, 12, or 1.
- Percentage mode applies the change only to base pay, while new-pay mode replaces the selected-period base amount.
- Current and new annual bonuses are added separately after base-pay annualization.
- The hourly equivalent divides annual base pay by entered typical annual hours and is not a legal overtime regular-rate calculation.
Rounding: Calculations retain floating-point precision across annualization and period conversion. Currency displays use up to two decimal places and percentages use two decimal places; payroll-specific rounding is not applied.
Limitations
- Supports money inputs up to 1 trillion, percentage changes from −100% to 1,000%, weekly hours above zero through 168, and paid weeks above zero through 53.
- Does not model varying hours, overtime, commissions, tips, equity, benefits, leave, bonuses other than the two annual inputs, taxes, deductions, exchange rates, pay dates, or jurisdiction-specific wage rules.
- The result is educational gross-pay arithmetic, not a pay stub, contract interpretation, legal wage determination, tax estimate, or individualized employment or financial advice.

Pay-period conversion rules
Hourly pay is annualized as rate multiplied by typical hours per week and paid weeks per year. Weekly pay uses 52 periods, biweekly uses 26, semimonthly uses 24, monthly uses 12, and annual pay uses one.
The new base-pay amount is either current pay multiplied by one plus the percentage change or the replacement amount entered directly. Annual base pay is then converted to monthly, biweekly, and hourly-equivalent comparisons without rounding intermediate values.
Gross comparison, not a payroll calculation
The result is straight-time gross arithmetic. It does not calculate withholding, deductions, overtime, commissions, equity, benefits, unpaid time, or a legally defined regular rate.
U.S. Department of Labor guidance explains that overtime and the regular rate can depend on actual weekly hours and which compensation is included. Those rules and jurisdiction-specific payroll requirements belong in a separate overtime or payroll calculation.
Frequently asked questions
▶What is the difference between biweekly and semimonthly pay?
This calculator treats biweekly as 26 periods per year and semimonthly as 24 periods per year. That difference changes the amount per paycheck.
▶Why are bonuses entered separately?
Keeping current and new annual bonuses separate shows whether total compensation changes for a different reason than base pay.
▶Can I model a pay cut?
Yes. Percentage mode accepts values down to −100%, and new-pay mode can accept a replacement amount below the current base pay.
▶Is the hourly equivalent an overtime regular rate?
No. It simply divides annualized base pay by entered annual hours. Legally defined regular-rate calculations can include or exclude compensation differently.
▶Does the result show take-home pay?
No. All amounts are gross. Taxes, deductions, retirement contributions, insurance, and other payroll items are excluded.
