Purchasing power explained: what your money actually buys

We often measure saving in dollars. But dollars are just a ruler. What really matters is how much real benefit your money can be exchanged for — your purchasing power.

Two ways to get richer

You can have more dollars and still be worse off, if prices have risen even more. And you can have the same number of dollars and be better off, if they go further.

• Nominal value: the number in your account.
• Real value: what the number actually buys.

It's the real value that shapes your everyday life.

An everyday example

Imagine a bag of groceries cost $500 a few years ago and $650 today. If your savings haven't grown at the same pace, you've effectively become poorer, even though the account figure looks the same.

Measure your saving by what it buys, not by how many zeros it has.

Measuring in something scarce

One way to understand long-term value is to measure in a unit that can't be diluted. Some use gold; others look at Bitcoin, precisely because the supply is fixed. It's not a recommendation, but an educational lens on what "value over time" means. Read more about inflation.
