What is Real return?

Your return after subtracting inflation. The true change in your purchasing power.

Real return is your investment gain after subtracting inflation — the honest measure of how much your purchasing power actually grew. The headline figure you see, the nominal return, includes the part that merely kept pace with rising prices, so it flatters your progress. Strip inflation out and what's left is the return that genuinely made you better off.

The distinction matters most over long periods, where inflation compounds alongside your gains. An investment can post a healthy-looking nominal return and still leave you barely ahead — or even behind — once prices are accounted for. Building real wealth means earning a positive real return; an investment that only matches inflation has run hard just to stand still.

A 7% headline return is 3% swallowed by inflation plus 4% of genuine gain. Only that cyan 4% grows what your money can actually buy.

For example

A 7% nominal return minus 3% inflation is a 4% real return — the only part that truly made you richer in what you can buy.

Why it matters to you

Real return is the number that actually determines whether your future self can buy more, because you'll spend your money on goods whose prices inflation has pushed up. Comparing investments on nominal returns alone can mislead — a 6% return in a 5% inflation era is worse than a 4% return in a 1% one. Focusing on real return also lowers the appeal of "safe" cash, which often delivers a negative real return once inflation is subtracted.

⚠ Judging success by the nominal number

A 5% return feels like a win — until you learn inflation was 6% that year, meaning your purchasing power actually fell. Celebrating nominal gains without subtracting inflation is how savers convince themselves they're getting ahead while quietly losing ground. Always net inflation out before deciding whether a return was any good.

Frequently asked questions

How do I calculate real return?

As a close approximation, subtract the inflation rate from your nominal return: a 7% return with 3% inflation is roughly a 4% real return. The precise formula divides the two ((1 + nominal) ÷ (1 + inflation) − 1), but for everyday use, simple subtraction is close enough.

Why is real return more important than nominal return?

Because you spend money on real goods, not on the headline figure. Real return tells you whether your buying power actually grew. A high nominal return in a high-inflation period can leave you no better off, while a modest return in a low-inflation period can be genuinely good.

Can a real return be negative?

Yes. If inflation is higher than your nominal return, your real return is negative — you have more dollars but they buy less than before. This is common for cash savings in higher-inflation periods, which is why leaving long-term money in cash is risky in real terms.

What's a good real return?

Over the long run, broadly diversified stocks have historically delivered real returns in the region of a few percent a year after inflation, though with plenty of ups and downs. The precise figure varies by period and market; the key is that it's positive and beats what cash would have earned.
