Buying power, made simple
The number is only half the story
Imagine you had $10 and a Bubble O' Bill cost $2. You could buy 5 ice creams.

Later, your $10 grows to $12, but the ice cream now costs $4. You can buy only 3 ice creams.

Your dollar value increased, but your buying power fell.

This tool compares what your asset could buy when you bought it with what it can buy today.
