Common questions

Inflation Calculator FAQs

Is this based on historical UK inflation data?+

No. You choose the annual rate, making this a future inflation and purchasing-power calculator.

What inflation rate should I use?+

There is no certain future rate. Comparing several plausible assumptions is more useful than relying on one figure.

Why does inflation compound?+

Each year’s price increase applies to a price that already includes previous increases.
