Buyer's guide

How to choose a buying power calculator

When picking a buying power calculator, the most important factor is whether you need to compare a specific dollar amount across two particular years. If that is your main goal, look for a tool that lets you input any start and end year without being locked into preset options. If you also want to see at-a-glance statistics — such as total inflation percentage or average annual rate — and are willing to tolerate a few ads on the screen, a calculator that displays those summary numbers can save you a step.
