How is it calculated?

Real return follows the Fisher equation: (1 + nominal return) ÷ (1 + inflation) − 1. The common shortcut “return minus inflation” misleads at high rates: with a 40% return and 35% inflation the gap looks like 5 points, but the real return is about 3.7%.

If tax is withheld, it comes off the gain first: a 40% return with 15% withholding is 34% after tax. The real return uses that net rate.

The amount in your account compounds yearly at the net return. The “in today’s money” figure brings it back to today with inflation.

Frequently asked questions

What is real return?

The return left after inflation; it shows how much your purchasing power grew. Even with a positive nominal return, the real return is negative if it’s below inflation.

Why isn’t real return just “return minus inflation”?

Because inflation also works on the return itself. At low rates the gap is small, but with high inflation the subtraction shortcut overstates the real return.

What inflation rate should I use?

For a past year, use that year’s actual inflation; looking ahead, use the inflation you expect. Your own basket’s inflation may differ from the official rate.
