The advertised interest often hides fees. APR rolls them all into one comparable percentage.

When you see a loan, the interest doesn't tell all: there can be analysis fees, administration fees, insurance. APR (Annual Percentage Rate) rolls everything into one yearly percentage.

Compare apples to apples

Two loans with the same interest can have a different APR because of fees. That's why, when comparing offers, you look at the APR, not just the interest. It's the number that doesn't lie.

Interest is what you're told. APR is what you actually pay.
