Interest rate versus APR
The interest rate prices only the borrowed balance. The APR also folds in upfront fees by asking: what rate would make these same payments fair if I had received the loan minus the fees? Because you repay principal computed on the full amount but only pocket the difference, fees raise the effective cost — a lot on short loans, barely on long ones.
Veelgestelde vragen
Why is the APR higher than the stated rate?
Fees reduce what you actually receive while the payment stays the same, so the implied rate rises. If a loan has no fees, its APR equals the stated rate exactly.
Should I compare loans by rate or APR?
APR, if all quotes include the same fee categories. Two loans with identical APRs cost the same over the full term; a lower rate with big fees only wins if you keep the loan long enough to outrun the fees.
