How it works

Inflation compounds like interest. The future cost of something priced at A today is A × (1 + i)^t. The purchasing power of A held as cash is A ÷ (1 + i)^t in today's dollars.

Real-world inflation varies year to year and by category of spending; a constant average rate is a simplification.
