What APR really means, and where it misleads you
APR expresses the yearly cost of credit including fees that are a condition of borrowing. Why it misleads on short loans, how term length changes cost at the same rate, and the four numbers to read on any disclosure.

The short version
- APR includes interest plus any fee that is a condition of getting the loan. It exists so two offers can be compared with one number.
- Term length changes cost more than the rate does: $1,000 at 29.99% costs $169.76 over 12 months and $341.84 over 24.
- Annualising a short loan produces a big percentage from a small dollar amount, which makes short credit look worse than it is.
- Compare the total of payments in dollars, then check the monthly payment fits. Not the other way round.
APR answers one question: what does a year of this cost?
Annual percentage rate expresses the cost of credit as a yearly percentage, including interest and any fee that is a condition of getting the loan. It exists so that two offers with different fee structures can be compared with a single number, which is why federal law requires it on every consumer credit disclosure.
The interest rate alone does not do that job. A loan can advertise a low interest rate and carry a high APR once an origination fee is folded in, which is exactly why the two numbers are shown separately.
What APR includes
- Interest charged on the balance.
- Fees that are a condition of getting the credit, such as origination fees.
- Not fees that only apply if something goes wrong, such as a late fee.
- Not optional add-ons you could decline and still get the loan.
We charge no origination fee, so our APR is pure interest.
Where APR misleads on a short-term loan
The number is comparable across offers. It is not a good guide to what you will actually hand over.
Same APR, very different cost
$1,000 at 29.99% APR over 12 months costs $169.76 in interest. The same amount at the same APR over 24 months costs $341.84. Identical rate, $172.08 more paid, because the balance is outstanding for twice as long.
Short loans look worse than they are
Annualising the cost of a two-month loan produces a large percentage from a small dollar amount. That is why a 35% APR advance for six weeks can cost less in dollars than a 20% card balance carried for two years.
Use APR to compare offers of the same amount and term. Use the finance charge, in dollars, to decide whether to borrow at all.
The four numbers on every credit disclosure
These appear in a box on your agreement, required by the Truth in Lending Act. Read them in this order.
Annual percentage rate
The yearly cost as a percentage. Use it to compare this offer against another of the same size and length.
Finance charge
The dollar cost of credit over the life of the loan. This is the number that tells you what borrowing actually costs you.
Amount financed
What you actually receive. If this is lower than what you signed for, a fee has been deducted from your funds.
Total of payments
Amount financed plus finance charge. Every payment added together, which is what leaves your account by the end.
The comparison most people get wrong
Comparing a monthly payment against another monthly payment tells you nothing about cost, only about cash flow. A lower payment usually means a longer term and a larger finance charge. Compare the total of payments, then check the payment fits.
Questions on this topic
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal alone. APR includes interest plus any fee that is a condition of getting the credit, which makes it the comparable measure between two offers.
Is a high APR always bad?
Not by itself. Annualising the cost of a short loan produces a large percentage from a small dollar amount, so a 35% APR advance for six weeks can cost far fewer dollars than a 20% balance carried for two years.
Does APR include late fees?
No. APR includes costs that are a condition of getting the credit. Fees that apply only if something goes wrong, such as late or returned payment fees, sit outside it.
Why do two loans with the same APR cost different amounts?
Because term length changes how long the balance is outstanding. $1,000 at 29.99% over 12 months costs $169.76 in interest; over 24 months at the same rate it costs $341.84.
Which number should I actually compare?
The total of payments and the finance charge, in dollars. Use APR to compare like-for-like offers, and the dollar figures to decide whether to borrow at all.
Does MDG add an origination fee to the APR?
We do not charge an origination fee at all, so our APR reflects interest only and the amount financed equals the amount you signed for.
