Real return: the number that tells you whether you actually made money

Someone tells you their savings account pays eight percent. Good, you think. Better than nothing.

Then you find out prices where they live went up twelve percent that year.

They did not make eight percent. They lost about three and a half. The bank paid them, the statement showed a bigger number every month, and they still ended the year able to buy less than when they started.

That gap has a name, and it is the only version of a return worth paying attention to.

The two returns

Nominal return is the number you are quoted. Eight percent. It is the change in how much money you have.

Real return is what is left after inflation. It is the change in what that money can actually buy, which is the only thing money is for.

Everything advertised to you is nominal. Nobody quotes a real return, because it is smaller and sometimes negative, and because it depends on where you live in a way a poster cannot cover.

Working it out

The quick version is the one worth memorising:

Real return is roughly your return minus inflation.

Eight percent interest, twelve percent inflation, roughly minus four percent. That is close enough for almost every decision you will make, and doing it in your head at the moment somebody quotes you a number is worth more than doing it precisely later.

If you want it exact, you divide rather than subtract:

real return = (1 + your return) ÷ (1 + inflation) − 1

On those figures that gives minus 3.57 percent rather than minus 4. Close, and here is why the difference is not worth fussing over at small numbers but is worth knowing at large ones:

The shortcut is nearly perfect when both numbers are small, and drifts as they grow. In a high inflation country it flatters things by more than a percentage point, and it always flatters, never the reverse.

If you would rather see it as money than percentages: put 100,000 in an account paying eight percent and you finish the year with 108,000. But the basket of things that cost 100,000 at the start now costs 112,000. You have more money and less of what you wanted. That is the whole idea, and it is why the number on the statement is not the point.

Where this shows up in an ordinary life

Your pay rise

You negotiate hard and get ten percent. It feels like winning.

If prices rose twelve percent over the same period, you took a pay cut of about two percent while being congratulated.

This is not an argument against asking for a raise. It is an argument for knowing what you are actually asking for. In a high inflation year, a raise that merely matches inflation keeps you exactly where you were, and anything below it means you agreed to be paid less for the same work. That is worth saying out loud in the conversation, and it is a far stronger case than "I would like more money".

It is also one of the quieter reasons people can feel broke on a rising income. Nothing went wrong. The ground moved.

Your savings

This is the one that catches everybody, because a savings account feels like the responsible choice and it is the one most likely to be quietly losing.

The account is not lying to you. It is paying exactly what it said. It simply is not paying enough to keep up, and no amount of discipline on your part changes that. If you want the fuller argument for what to do about it, that is a post of its own. The point here is narrower: you cannot tell whether an account is helping or hurting until you have subtracted inflation, and most people never do.

Any investment anyone offers you

"Fifteen percent a year" means nothing on its own. In a country with three percent inflation it is excellent. In one with eighteen percent it is a slow loss dressed up as a gain.

This is the honest defence against a lot of nonsense, and a more reliable one than instinct. It also cuts the other way: a return that sounds boring can be genuinely good, and a return that sounds thrilling can be the kind that should worry you.

Your debt, going the other way

Here is the part nobody mentions, and it is the one place inflation is quietly on your side.

If you owe 50,000 at a fixed rate, and prices rise twelve percent, then a year later that 50,000 is worth about 44,600 in today's money. The number you owe did not change. What it costs you to settle it did.

Fixed-rate debt gets easier to carry as prices rise, provided your income rises too. Which is the real condition, and why this is a footnote rather than a strategy. It does not make borrowing free, it does not apply to a variable rate that moves with everything else, and it is no reason to go and find some debt. But it does explain why paying off a very cheap fixed-rate loan early is often not the win it feels like, when that money could be doing more elsewhere.

Whose inflation, though

One honest complication. The inflation figure you read is an average of a basket of things a statistician chose. Yours is not that basket.

If most of your money goes on food, transport and rent, and those rose faster than the average, your personal inflation is higher than the published number and your real return is worse than you calculated. If you own your home and cook most of your meals, it may be lower.

You do not need to compute your own index. Just know that the official number is a reasonable starting point and not a personal fact, and that if your own bills feel like they are climbing faster than the news says, they may well be.

The habit worth building

Whenever someone quotes you a number, subtract inflation before you react.

A savings rate. A pay rise. A fund's performance. A government bond. A promise from a friend with an opportunity. All of them are quoted nominal, all of them sound better than they are, and the subtraction takes two seconds.

It will make you harder to impress, which is the point. Most people have never once asked whether a return beat inflation, which is how an account paying interest every single month can leave someone poorer over a decade while they feel they were being careful.

The number that matters is not how much money you have. It is what it can buy.

If you track your money in Wealthpadi, the balances and returns are nominal, exactly as your bank quotes them, so this subtraction is still yours to do. What it does give you is the honest starting figures to do it with, and somewhere to see whether the total is genuinely moving year on year rather than only looking like it.

This is one term from the plain English money glossary. If you want the mechanic underneath the numbers, compound interest is the same force working for you, and inflation is it working against you.
