Common questions

Inflation Calculator FAQs

What inflation rate should I use?

A recent official consumer inflation rate is a useful starting point, but you can also test lower and higher scenarios.

Does inflation compound?

Yes. Each year’s price increase applies to the previous year’s higher price, so the effect compounds.

Is this the same as purchasing power?

No. This calculator projects a future price; the Purchasing Power Calculator estimates what today’s money may be able to buy later.
