What inflation means for your money

Inflation is the rate at which prices rise, so it quietly erodes the buying power of cash. If your savings grow more slowly than inflation, you can actually put money away and still be worse off in real terms — check your Personal Savings Allowance and consider a Stocks & Shares ISA for longer-term goals.

Inflation also shapes the Bank of England base rate: the Bank raises rates to cool inflation and cuts them as it falls. That feeds through to mortgage costs and savings rates alike. For pensioners, inflation is why the State Pension triple lock matters.

Frequently asked questions

What is the UK inflation rate right now?

UK CPI inflation is 2.6% in the 12 months to June 2026, according to the ONS. The Bank of England's target is 2%.

How do I work out what money was worth in the past?

Use the calculator above: enter an amount and a year, and it shows the equivalent buying power in another year using the ONS Consumer Prices Index. For example, it will tell you what £100 in 2000 is worth today.

What was the highest UK inflation recently?

CPI inflation peaked at 11.1% in October 2022 during the cost-of-living crisis, before falling back. It reached a recent low of 1.7% in August 2024.

Why does inflation matter for my savings?

If your savings earn less interest than the inflation rate, their real buying power falls over time. To protect your money you generally want a return at or above inflation — which is why cash rates and ISAs matter.
