How to Calculate a Pay Raise Percentage (and What It's Really Worth)
A raise percentage is the increase divided by your current salary: (new − old) ÷ old × 100. The number that actually matters, though, is the real raise — what is left once inflation and tax have taken their share.
The calculation, both directions
- Raise percentage: (56,000 − 52,000) ÷ 52,000 = 7.69%.
- New salary from a percentage: old × (1 + rate/100). 52,000 × 1.05 = 54,600.
- In Excel or Sheets: =(B2-A2)/A2 formatted as a percentage.
- Hourly to annual: rate × hours per week × 52 before comparing.
Real versus nominal
Divide, do not subtract: real raise = (1 + nominal) ÷ (1 + inflation) − 1. A 7.69% raise with 3% inflation leaves about 4.55% of genuine buying power, not 4.69%. Any raise below the inflation rate is a pay cut in real terms, however positive the headline sounds.
What the gross figure hides
- Tax bands: crossing a threshold means the take-home rise is smaller than the gross rise.
- Benefits tied to salary — pension contributions and life cover — rise with it.
- Bonus targets are often a percentage of base, so the raise compounds into them.
- A title change without a market-rate adjustment can leave you behind on the next move.
Negotiating with the number
Anchor on market data for the role and location, quantify what changed in your scope since the last review, and ask for a specific figure rather than a range. If budget genuinely will not move, negotiate the items that cost less: a title, a bonus target, additional leave or a review date in six months with defined criteria.
Key takeaways — Pay Raise Percentage Calculator
- Raise % = (new − old) ÷ old × 100.
- Real raise divides by inflation — it never simply subtracts it.
- Check net pay and the tax band, not just the gross percentage.
