Compound Interest Guide
Compound Interest for Students
A simple explanation of compound interest for students learning money basics.
Think of it as growth on growth
Compound interest means money can grow, and then the growth can also grow. This is why teachers often describe it as a snowball effect.
The snowball starts small, but if it keeps rolling, it can collect more snow over time.
A classroom example
If $100 earns 10%, it becomes $110 after one year. If the $10 stays in the account, the next 10% is calculated on $110, not just $100.
That second year earns $11 instead of $10. The difference is small, but the idea becomes powerful over many years.
Why it matters early
Students have one advantage that older adults cannot create: time. Even small savings habits can benefit from many years of compounding.
The calculator can help students see how time changes the result.
