Rising cost over the years

The formula

future cost = amount × (1 + rate/100)^years

Inflation compounds exactly like interest, just working against you: the same basket costs more each year, and the same cash buys less. This uses an assumed average rate, so treat the result as an illustration — real inflation varies year to year and by what you actually buy.
