How the calculations work

Future equivalent uses compound inflation to show how much you would need in the future to match today's buying power: amount × (1 + inflation rate)years.

Worth in today's money shows how much buying power the same amount would keep after inflation: amount ÷ (1 + inflation rate)years.

The year-by-year breakdown applies the same two formulas to every year in turn, so you can see how the gap widens as inflation compounds.

Actual inflation varies year to year. The Bank of England's long-term inflation target is 2%, but recent averages can differ.
