7% nominal return minus 3% inflation: Fisher formula gives 3.88% real return (not 4% due to compounding interaction). Cash at 3% during 3% inflation = 0% real. Equity typically beats inflation by 4-5% real; cash barely breaks even after tax.

Quick example

With nominal return of 7% and inflation rate of 3%, the result is 3.88%. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Nominal Return and Inflation Rate. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Fisher equation: (1+nominal)/(1+inflation) - 1. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why investors run this

Most people's intuition for compounding is wrong — not because the math is hard, but because linear thinking doesn't account for curves. Running numbers through a calculator like this one is the cheapest way to recalibrate that intuition before making an irreversible decision about contribution rate, asset mix, or retirement age.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.

Where to go next

This calculation rarely sits alone in a planning exercise. If you're running these numbers, you'll probably also want the real rate of return calculator, the inflation calculator, and the inflation adjusted return calculator — each one answers a different question in the same territory. Treating them as a set rather than in isolation usually produces a more honest picture.

Example Scenario

Real return produces an inflation-adjusted figure based on the inputs provided.

Inputs

Nominal Return:7
Inflation Rate:3
Expected Result3.88%

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Subtraction approximation?
Close for small numbers. 7% - 3% ≈ 4% but actual 3.88%. Gap widens at higher rates.
Why use real return?
Real return shows actual purchasing power growth. Nominal is before inflation erodes value.
Cash struggling?
Historic reality: savings rates track inflation roughly. Real return on cash often 0 or negative after tax.
Negative real return?
Possible — rate below inflation. Common for cash in high-inflation periods. Purchasing power falls.
