We use the Bank of England's 2% target for the years ahead. Prices are rising 3.5% a year now (ONS CPI, September 2026).
This is an estimate, not financial advice. Nobody knows future inflation; change the rate under More options to try others.
Why inflation matters
If your savings earn less than inflation, they lose buying power every year even as the balance grows.
To keep pace with 2.5% inflation, your money needs to grow by at least 2.5% a year after tax.
