Inflation Calculator

What would your pay have bought in 1937?

Money is a slippery thing. The same numbers meant something wildly different within a single lifetime. Enter your monthly take-home pay below and see what it would have bought in Britain in 1937 — then compare that with today.

It's a vivid way to feel inflation — not as an abstract percentage, but in houses, cars and loaves of bread — and a small window onto how much the ground beneath our assumptions can shift without us noticing.

Whole pounds is fine — nothing you type is stored or sent anywhere.

The same money, two different truths

Why do the numbers diverge so wildly? Some things we learned to make cheaper. Some things we can't.

We got so good at making these that the price barely moved. As manufacturing improves, living standards rise — but it masks the quiet erosion of our money's value.

You can't mass-produce land. So housing is the truest mirror we have of the pound's real loss of value.

Measured in televisions, an annual salary of £150 from 1937 is worth about £1,000 today; in houses, about £75,000. Official inflation splits the difference near £14,000 — but that average hides the real story: money has been quietly eroded, clearest in the price of a home, even as technology raised our standard of living.

So what actually drives house prices?

Here's the whole story on one chart. Since 1937 the average UK house has risen about 510× in price, and the money supply about 880× — the two climb together. Official inflation (RPI, the price of everyday goods) has risen only about 95×, and the population barely 1.5×. The price of houses has inflated as the money supply has been inflated.

  • Average house price
  • Broad money (money supply)
  • Official inflation (RPI)
  • Population
UK house prices, money supply, inflation and population since 1937, each as a multiple of its 1937 level. By 2026 average house prices were about 510 times their 1937 level and the money supply (M4ex) about 880 times, both rising steeply from the 1970s. Official inflation (RPI) reached only about 95 times and population only about 1.5 times, staying near the bottom. 0× 200× 400× 600× 800× 1000× 19371960197019801990200020102026 ×513×878×95×1.5

And there's a mechanism behind it. In the modern economy, most money is created by commercial banks the moment they make a loan — and mortgages are the largest channel of all. So lending to buy a house creates new money and bids up house prices at the same time, even as population and household numbers barely shift. The two lines aren't a coincidence; they're two views of the same thing.

Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower’s bank account, thereby creating new money. — Bank of England, Money creation in the modern economy (2014)

Now run inflation forwards

The same force keeps working on the money you keep. Enter roughly what you have in savings, then compare two ways of measuring inflation: the official Consumer Price Index (CPI), and the growth of the money supply — what some argue is the truer picture. Both show your savings' worth in today's money if the cash simply sits there — the same pounds, buying steadily less.

A round number is fine — nothing you type is stored or sent anywhere.

Enter your savings to see how much they'll still buy in years to come.

Official inflation (CPI)

2.8% a year

The Bank of England targets 2%; CPI has averaged about 2.8% a year since 1988.

  • Now — worth of goods
  • In 30 years — worth of goods
  • In 60 years — worth of goods
  • In 90 years — worth of goods

Money-supply growth the “real” rate

9.8% a year

UK broad money grew about 9.8% a year on average across 1961–2017.

  • Now — worth of goods
  • In 30 years — worth of goods
  • In 60 years — worth of goods
  • In 90 years — worth of goods

Every figure is buying power in today's prices — what the money could still purchase, not how many pounds sit in the account.

The value of your money is melting away like an ice cube in the sun.

The number of pounds never changes — what they can buy quietly disappears.

Ordering the paperback from the EU?

Sadly I can't currently post paperbacks to the EU. New customs rules mean a book sent from the UK arrives with import charges almost as large as the price of the book, and I don't want that landing on your doorstep.

For now, the paperback is on Amazon across the EU. Amazon shows any import taxes and charges at checkout, so you'll see the full cost before ordering. Pick your country's store:

No store for your country? Most of these deliver across the EU. The eBook and audiobook aren't affected, so you can still buy those here.
