It is the number every lender must publish and almost nobody explains. Here is what it measures, why ours looks larger than our fee, and the one situation where it will mislead you badly.
Possible Finance quotes you a $350 fee. Another quotes 30.9% APR. A third quotes $195.83 a month. All three can describe exactly the same $2,000 loan, and only one of them is designed to be comparable.
A price is what you hand over: $350. A speed is how fast the cost accumulates relative to the money you are holding and how long you hold it. APR is the second kind of number. It takes the whole payment schedule — every dollar out, on every date — and solves for the annual rate that would produce it.
That solving step is why APR cannot simply be read off the fee. A $350 fee on $2,000 is 17.5% of the amount borrowed. But you do not hold all $2,000 for the full year: you start repaying after thirty days, and by month six roughly half the principal is gone. The fee is charged against the whole amount while your actual average balance is far lower, and annualising that produces about 30.9%.
Before APR disclosure was mandatory, lenders competed on whichever number flattered them: a small dollar fee here, a low monthly payment there, a rate quoted per week somewhere else. Comparison was effectively impossible, which suited the lenders. Requiring one standardised figure was the fix.
It works well when the products being compared have a similar shape — two installment loans, or two credit cards. It works badly across shapes, and it works worst of all on very short credit.
Annualising assumes the arrangement repeats for a year. A two-week product with a $15 fee per $100 borrowed does not repeat for a year in the borrower’s mind, but the arithmetic assumes it does, and the resulting APR runs into the hundreds of percent.
That number is not wrong, and it is a fair warning about what renewing such a product for a year would cost. But it tells you very little about a single two-week loan cleared on time, and treating it as a straight price comparison against a twelve-month installment loan will mislead you. The honest comparison there is total dollars repaid, which is exactly what payday loan alternatives sets side by side.
APR describes the cost of a schedule. It says nothing about whether the schedule concludes. A product with a moderate APR that renews indefinitely can extract more from a borrower than a higher-APR loan that ends on a fixed date, because the first one never stops charging and the second one does.
So APR is necessary and insufficient. Read it, then ask the two questions that sit underneath it: what is the total in dollars, and on what date is the final payment? Our note on fair versus predatory lending is built around exactly that pair.
Every row below describes the identical loan. Any of them could headline an advertisement, which is the whole problem.
| How it is quoted | The figure | What it hides |
|---|---|---|
| Flat fee in dollars | $350.00 | How long you hold the money |
| Fee as a share of the amount | 17.5% | That it is not an annual rate |
| Monthly payment | $195.83 | How many payments there are |
| Representative APR | 30.9% | Whether the loan actually ends |
| Total repaid | $2,350.00 | Nothing — this is the honest one |
If you only ever ask one question of a lender, make it the last row.
The same $2,000 at each term we offer. Watch the fee climb while the APR stays almost flat — that is APR doing its job, holding the speed constant while the distance changes.
| Term | Flat fee | Fee as % of $2,000 | Monthly | Total repaid | APR |
|---|---|---|---|---|---|
| 6 months | $175.00 | 8.8% | $362.50 | $2,175.00 | 29.4% |
| 12 months | $350.00 | 17.5% | $195.83 | $2,350.00 | 30.9% |
| 18 months | $525.00 | 26.2% | $140.28 | $2,525.00 | 30.9% |
| 24 months | $700.00 | 35.0% | $112.50 | $2,700.00 | 30.7% |
The fee quadruples between the first row and the last. The APR moves by a point and a half. Both facts are true, and only one of them is what leaves your account — which is the argument for reading the total alongside the rate, every time. You can reproduce any row on the loan calculator, and the whole price list is on rates and fees.
The cost of credit expressed as a yearly rate, solved from the payment schedule rather than quoted from the fee. It exists so that loans of different sizes and lengths can be compared on one number.
Because they measure different things. The fee is a price paid once; the APR annualises that price across the time you hold the money. A fee of 17.5% of the amount borrowed over twelve months works out near 30.9% APR.
Annualising a cost that was only charged for a few weeks produces a large number. A $100 fee on a two-week loan is a modest sum and a spectacular APR, which is why APR alone is a poor guide for very short credit.
Usually, but not always. APR ignores whether the loan actually ends. A product with a modest APR that renews indefinitely can cost far more than a higher-APR loan that finishes on a fixed date.
Both. Use APR to compare products of similar shape, and use the total dollars repaid to sanity-check what you will actually hand over. If a lender will not state the total, that is the answer.
