What does the result mean?

APR makes offers with different fees easier to compare.

What should I check before relying on it?

It is an estimate, not a lender disclosure.

Why is APR usually higher than the stated interest rate?

APR folds in most required lender fees on top of interest, expressed as a single annualized rate — since it captures more of the loan's true cost, it's typically higher than the bare interest rate alone.

Can I use APR alone to compare loans with different terms?

It's a good starting point, but the same fee has a bigger annualized effect on a short-term loan than a long-term one, so also compare the total dollar cost, not just the percentage.
