How the Inflation-Adjusted Return Calculator Works
A 12% return sounds good until you remember that prices are also rising every year. This calculator shows your real return -- what your money actually grows by in terms of purchasing power, after stripping out the effect of inflation -- alongside the nominal (headline) return most investments are quoted in.
Enter the amount you're investing, the nominal annual return rate you expect, an inflation rate assumption, and the number of years. The calculator projects both the nominal corpus (what your statement will show) and the real corpus (what that amount could actually buy at today's prices), and charts them side by side so the gap becomes visible over time rather than an abstract percentage.
Real Rate (%) = [ (1 + Nominal Rate) ÷ (1 + Inflation Rate) − 1 ] × 100 (the Fisher Equation)Worked example
At a 12% nominal return with 6% inflation, your real rate of return is roughly 5.66% -- not 6% (12% − 6%) as a quick subtraction might suggest, because inflation compounds against your gains too, not just against the principal.
Frequently asked questions
Why isn't the real return just nominal minus inflation?
Simple subtraction (12% − 6% = 6%) is a common approximation, but it slightly overstates the real return because it ignores the compounding interaction between the two rates. The Fisher Equation this calculator uses is the mathematically precise version.
What inflation rate should I use?
India's long-term average CPI inflation has generally been in the 5-7% range, though it varies year to year. Many long-term planners use 6% as a reasonable working assumption, but you can adjust this to match a specific goal -- education or healthcare costs, for example, tend to inflate faster than general CPI.
If my real return is low, does that mean I should avoid this investment?
Not necessarily -- a low or even negative real return usually points to picking a different asset mix (e.g. more equity for long-term goals) rather than avoiding investing altogether. Keeping money in cash or a very low-yield account almost always has a real return near zero or negative once inflation is accounted for.
