What Is Compound Interest?

Imagine you plant a tiny apple tree in your backyard.

The first year:

• the tree grows a few apples

Instead of eating all the apples, you plant the seeds from those apples too.

Now you have:

• the original tree
• new baby trees growing beside it

A few years later:

• all the trees start producing apples
• those apples create even more seeds
• more trees keep growing

Eventually:

The growth starts speeding up on its own.

That is basically how compound interest works.

Compound interest happens when:

Your money earns money, and then that new money also starts earning money too.

For example:

Imagine you invest $100.

If it grows 10%:

• you now have $110

Next time, you do not earn growth on just the original $100 anymore.

Now you earn growth on:

The full $110.

Over time:

• the growth builds on itself
• the gains become larger
• the process speeds up

This is why investors start early whenever possible.

Because compound growth becomes more powerful with:

• time
• consistency
• reinvesting

This is also why dividend investors reinvest dividends.

Instead of taking the cash:

• they buy more shares
• those shares may produce more dividends
• which can buy even more shares later

At first, compound growth looks slow.

But after many years:

Small consistent growth can become surprisingly large.

In simple terms:

Compound interest is when your money starts making money on top of the money it already made before.
