Two lenders quote you a loan. One says 9.5%, the other says 10.2%. Obvious winner, right?
Not necessarily. If the first number is an interest rate and the second is an APR, you’re comparing two different things, and the “cheaper” loan might cost you more.
The difference
The interest rate is the cost of borrowing the principal. That’s it.
The APR is the interest rate plus most of the required fees, expressed as a yearly rate. It’s an attempt to make loans comparable by folding the fees back in.
Federal disclosure rules require lenders to show you the APR, which is exactly why you should anchor on it. Marketing pages love to lead with the rate; the disclosure has the APR.
An example
$20,000 personal loan, 5-year term.
- Lender A: 9.5% rate, 5% origination fee. You receive $19,000 but repay based on $20,000. Effective APR lands somewhere around 11.7%.
- Lender B: 10.2% rate, no fees. APR is 10.2%.
Lender B is cheaper despite the higher headline rate. Over five years the gap is several hundred dollars.
This is the entire reason APR exists as a required disclosure, and it’s still the most common way people pick the wrong loan.
Where APR gets slippery
It’s a good tool, not a perfect one.
Mortgages: APR assumes you keep the loan the full term. If you’ll sell or refinance in six years, a loan with high closing costs and a low rate looks better in APR terms than it’ll actually be for you. Points paid upfront work the same way — they pay off over time you might not have.
Credit cards: APR and interest rate are effectively the same thing, since there are no origination fees to fold in. But cards have multiple APRs — purchases, cash advances, balance transfers, penalty rate — and cash advance APR is usually much higher and starts accruing immediately, with no grace period.
Variable rates: The quoted APR is a snapshot. It can move.
What to ask for
When you’re shopping, request the same thing from every lender: APR, term in months, monthly payment, and total amount repaid over the life of the loan.
That last one is the real comparison. Total repaid cuts through every trick — rate games, term stretching, fee shuffling — because it’s just the sum of what leaves your bank account.
A lender who won’t give you those four numbers plainly is telling you something.
And check for prepayment penalties
Neither APR nor total repaid captures a prepayment penalty, and it changes the math completely if you intend to pay early. Most reputable personal lenders don’t have them anymore. Ask anyway.
Two minutes of asking beats five years of paying.
