Compound interest

Drag the sliders to see how time builds wealth.

The idea

Here's the magic trick that builds wealth: your money earns money, and then THAT money earns money too. This is called compound interest. At first it grows slowly, but over many years the snowball gets huge. The secret ingredient is time — the earlier you start, the bigger it grows. ❄️

Words to know

Compound interest
When your money earns money, and then your earnings start earning too — growth that snowballs over time.
