How it works

The calculator divides your money by the build-up of inflation, year after year. For example, with 3% inflation over 10 years, $11,000 would buy what $8,185 costs today, and you would need $14,783 to buy the same as today.

A quick way to see it

The rule of 70 gives an idea of how fast inflation works. Divide 70 by annual inflation and you get a rough idea of how many years it takes prices to double, and so for your money to buy half as much. At 2% that is about 35 years, and at 7%, about 10.

Good to know

  • It assumes the same inflation every year. In reality it changes, and some years see much bigger rises than others.
  • Inflation is an average. What rises for you depends on what you spend your money on, such as housing, food or energy.
  • It does not include what your money could earn over time, such as interest, or taxes and fees.
