Why isn't real raise just "nominal raise minus inflation rate"?

That simpler subtraction (10% − 6% = 4%) is a common approximation, but it's not exact -- it ignores that inflation compounds against your old salary while your raise compounds on top of it, and the two effects don't just subtract cleanly, especially at higher rates or over multiple years. The precise ratio-based formula this calculator uses gives the mathematically correct answer (3.77% in the example above, not 4%).

Can a real raise be negative even with a positive nominal raise?

Yes -- if your nominal raise percentage is smaller than the inflation rate over the same period, your paycheck grew in rupee terms but actually buys less than before. This is a common and important distinction: a "raise" that doesn't outpace inflation is really a pay cut in purchasing-power terms, even though the number on your payslip went up.

Why does the "years since last raise" field matter?

Inflation compounds over time, so a 5% raise after 1 year and a 5% raise after 3 years (with the same annual inflation rate) represent very different real outcomes -- the 3-year gap has had three years of compounding inflation eating into purchasing power, while your salary only jumped once, at the very end.

What inflation rate should I use?

A commonly used input is your country's official consumer price index (CPI) inflation rate for the relevant period, though your personal cost-of-living increase (driven by your specific spending pattern -- rent, groceries, etc.) can run higher or lower than the headline CPI figure, so use whichever rate best reflects the actual cost increases you've experienced if you want a more personal answer.

Real Raise Calculator

A 10% raise during 6% inflation isn't a 10% improvement in what you can actually buy. Enter your old and new salary to see your real, inflation-adjusted raise.

How Real Raise Calculator Works

A raise's headline percentage only tells you how much bigger your paycheck is, not how much more it can actually buy -- inflation erodes purchasing power over the same period, so a 10% raise during 6% inflation is a much smaller real improvement than the 10% figure suggests. This calculator strips out inflation to show your true, purchasing-power-adjusted raise.

Formula & Method

Real raise is calculated as (New Salary ÷ Old Salary) ÷ (1 + inflation rate)ⁿ − 1, where n is the number of years since your last raise -- this compounds inflation over the full period rather than simply subtracting a flat inflation percentage from your nominal raise, which stays accurate even over multiple years or at higher inflation rates. The "break-even salary" is what your old salary would need to become just to keep pace with inflation (Old Salary × (1 + inflation)ⁿ), and comparing your new salary to that break-even point shows your purchasing power gain or loss in actual currency, not just percentage terms.

Worked Example

Going from ₹8,00,000 to ₹8,80,000 (a 10% nominal raise) during a year of 6% inflation: the break-even salary needed just to keep pace is ₹8,00,000 × 1.06 = ₹8,48,000. Your real raise is (8,80,000 ÷ 8,00,000) ÷ 1.06 − 1 ≈ 3.77% -- a meaningfully smaller number than the 10% headline figure, though still a genuine gain in purchasing power (about ₹32,000 above break-even).

Real raise isn't just nominal raise minus inflation — it's calculated exactly as (New Salary ÷ Old Salary) ÷ (1 + inflation)ⁿ − 1, so it stays accurate over multiple years and at higher rates.
