Inflation Calculator: limits and things worth knowing

• Purchasing power erodes compound. At 3% a year, money loses half its value in about 23 years — the rule of 72 divided by the rate gives a good approximation.
• A pay rise below the inflation rate is a real-terms pay cut, which is the calculation most people actually want here.
• Headline inflation is an average across a basket of goods and rarely matches your personal experience, since housing, energy and food move differently and take up different shares of different budgets.
• Historical comparisons across long periods are approximate: the basket itself changes, and goods that did not exist cannot be priced.

Is it private and secure?

Your privacy is built in. Inflation Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
