What is interest on loans?

The meaning

When you borrow money (a credit card, a car loan, a mortgage, etc.), you pay back more than you borrowed. That extra amount is called “interest”, and it’s expressed as a percentage. Paying those off before you start heavily investing usually makes the most financial sense. When rates are high, it costs more to borrow. When rates drop, the opposite happens.

Example
$5,000card balance×24%interest rate≈$1,200a year in interest
Paying off a 24% card is like earning 24%, with no market risk.
Walk through the numbers

A $5,000 credit card balance at 24% interest costs about $1,200 a year if you only make small payments. Paying it off is like earning a 24% return.

Why it matters

High-interest debt grows faster than most investments, so paying it down usually comes before investing.
