How the figures are calculated, step by step

1. Convert the annual inflation rate from a percentage to a decimal by dividing by 100.
2. Raise (1 + inflation rate) to the power of the number of years to get the price growth factor.
3. Multiply the amount by the growth factor for the future price of the same item.
4. Divide the amount by the growth factor for the purchasing power of today's amount at the future date.
