A 10.9% Loan With a 6% Fee Is a 14.23% Loan

Two lenders quote you a personal loan. One offers 12.9% with no fee. The other offers 10.9% with a 6% origination fee. The second looks two points cheaper and is nearly a point and a half more expensive. The fee does not just add a cost; it changes the rate.

Why a fee behaves like interest

Borrow $15,000 at 10.9% over 48 months and the payment is $386.95. With a 6% origination fee deducted at closing, $900 never arrives and you receive $14,100. Your payment does not change, because it was calculated on the full $15,000.

So you are paying $386.95 a month for four years in exchange for $14,100 of cash. Solving for the rate that makes those numbers balance gives 14.23%.

The other way lenders handle the fee

Some lenders add the fee to the balance rather than deducting it, so you receive the full amount you asked for and borrow more than that. If you need $15,000 in hand with a 6% fee, you borrow $15,957.45 and the payment rises to $411.65.

The economics are close to identical. What changes is the presentation: the first method makes your loan look smaller, the second makes your payment look larger. Neither changes the fact that a fee has been charged, and both should be converted to a true rate before comparing.

What APR is supposed to do, and where it stops

This is precisely the problem APR was created to solve. A properly disclosed APR on a personal loan already includes the origination fee, which is why a loan advertised at 10.9% may show an APR of 14.23% in the disclosure. The interest rate and the APR appearing as different numbers is not an error; it is the fee made visible.

• Compare APR to APR, never a rate to an APR. Most misleading comparisons come from putting one lender's headline rate against another's APR.
• On mortgages, APR includes origination and discount points but excludes many third-party costs, so two mortgage APRs are less directly comparable than two personal loan APRs.
• APR assumes you hold the loan for the full term. Repay early and the fee is spread over fewer months, so your realised cost is higher than the disclosed APR.
• APR ignores compounding frequency, which is why a credit card's APY exceeds its APR. For an instalment loan with monthly payments this distinction is minor.

The early repayment trap

The fee is charged once, at the start, whatever happens afterwards. Repay the 6% fee loan after twelve months instead of forty-eight and the $900 has been spread over a quarter of the intended period, so the effective annual cost rises sharply.

This has a practical consequence. If you expect to repay early, perhaps because a bonus or a house sale is coming, weight the fee far more heavily than the rate. A no-fee loan at a higher stated rate is usually the better instrument for a borrower who intends to clear it quickly, and the better one for a borrower certain to run the full term is often the reverse.

Fees that are not the origination fee

1. Prepayment penalties. Uncommon on personal loans, present on some auto and portfolio loans. They convert the early repayment decision into an explicit cost.
2. Late fees and returned payment fees. Ordinary and avoidable, but worth knowing before rather than after.
3. Credit insurance or payment protection sold alongside the loan. Frequently expensive relative to the cover provided, and almost always optional despite how the conversation is framed.
4. Administration or documentation fees, which are simply an origination fee under a different name and belong in the same calculation.

Applying it

Get the payment, the term, and the net cash for each offer. Solve for the rate that ties them together, or read the disclosed APR, which should give the same answer. Then rank by that single figure. A loan with a higher headline rate and no fee frequently wins, and it will never win if you compare on the headline rate alone, which is exactly why headline rates are what get advertised.
