Simple Approximation

Real return uses the Fisher equation: (1 + nominal) ÷ (1 + inflation) − 1. This is a planning estimate, not financial advice — confirm official rates before you rely on it.

Frequently Asked Questions

Inflation-adjusted return

See whether an investment beats inflation

Use a nominal return and inflation rate measured over the same annual period. The country selector changes only the display currency.

  • Exact real rate: (1 + nominal) ÷ (1 + inflation) − 1.
  • Simple approximation: nominal minus inflation; this can diverge materially when rates are large.
  • Projection: assumes both rates stay constant for every selected year.

Not included: tax, fees, contributions, withdrawals, exchange-rate changes or a changing inflation basket.

Frequently Asked Questions

Does country selection load inflation?

No. It changes the currency label only. Enter inflation from the source and period relevant to your analysis.

Can nominal return or inflation be negative?

Yes, provided each rate is above −100%. The exact equation requires positive gross factors.

Is purchasing power a forecast?

No. It is a constant-rate scenario based only on the entered nominal return and inflation.

What is the Fisher equation?
For this calculator, Real Rate = ((1 + Nominal Rate) / (1 + Inflation Rate)) − 1. Nominal minus inflation is shown separately as an approximation.
Why can a positive nominal return have a negative real return?
If prices rise faster than the investment grows, the future amount buys less even though its nominal balance is higher.
Which country currently offers a positive real return?
This page does not rank countries. The result depends on the specific investment return, inflation measure, period, tax, fees and currency exposure.
Why show the simple approximation?
It makes the common nominal-minus-inflation shortcut visible so you can compare it with the exact multiplicative result.
