What a small loan really costs

Updated 6 November 2026 · a plain guide from NewPostFinance, a connection service, not a lender

The cost of a small loan is the total you repay minus the amount you borrowed, which the agreement calls the finance charge. The APR tells you how expensive the loan is for its length, so the two numbers answer different questions, and you need both before you sign.

The three numbers on every agreement

Amount financed. What actually reaches your account. If an origination fee is taken out first, this can be less than the amount you asked for.
Finance charge. Every dollar of interest and fees you will pay over the life of the loan, assuming you pay on time. This is the cost in dollars.
APR. The annual percentage rate. It turns the finance charge into a yearly rate so that a two-week loan and a two-year loan can be compared on one scale. On a short loan the APR is often high even when the dollar cost is modest, because the time is short.

Federal rules require lenders to show all three before you sign. If you cannot find them, you have not reached the agreement yet, and nothing should be signed until you have.

A worked example, in words

Suppose a lender offers you the amount you asked for and asks for it back in four equal payments over two months, with a finance charge printed next to the total. Add the finance charge to the amount financed and you have the total of payments. Divide the total by four and you have each payment. If any of those three figures surprises you, that surprise is the point of reading the agreement; it is far cheaper to be surprised now than on a due date.

Now imagine a second lender offers a lower payment but spreads the loan over six months. The payment looks friendlier. The total of payments is often higher, because interest ran for longer. Neither offer is automatically better. One fits a tight month, the other fits a tight budget. Decide which problem you are solving, then pick.

Fees that change the real cost

Origination fee. Taken from the amount financed or added to the balance. Either way it belongs in the finance charge.
Late fee. A fixed charge or a percentage of the missed payment. Check the grace period, if any.
Returned payment fee. Charged when a debit fails. Your bank may charge its own fee on top.
Prepayment penalty. Rare on small loans but worth a look. Paying early should reduce the finance charge, not add a fee.
Optional add-ons. Credit insurance or membership products presented at signing are optional. Declining them cannot be a condition of the loan.

A two-minute comparison: write down the total of payments, the number of payments and the date of the last one for each offer. The offer with the lower total costs less; the offer with the smaller payment is easier month to month. Choose with both numbers in front of you.

Why short loans show high APRs

APR assumes the loan runs for a year. A loan that lasts two weeks is scaled up as if it were renewed twenty-six times, which is why a modest dollar charge can show as a three-figure percentage. That does not make the number wrong; it makes it a warning about what happens if a short loan is rolled over or extended. The lenders in our network can offer APRs that are high, and some may exceed 200 percent. Read the figure, understand what it means for your plan to repay, and borrow the smallest amount that solves the problem.

Questions to ask the lender before signing

What is the total of payments, and on what dates?
Is there any fee that is not already in the finance charge?
What happens if a payment is one day late, and is there a grace period?
Can I repay early, and does that reduce the cost?
How do I reach a person if something goes wrong?

Where NewPostFinance fits

We do not set any of these numbers. NewPostFinance carries one request for $100 – $5,000 to a network of lenders; each lender writes its own terms and must show them to you before you sign. Sending the request is free, and checking your options won't affect your credit score. To see the steps between the request and the agreement, read what happens after you send a loan request, and for timing, ACH cutoff times and your loan deposit.

Short answers

Is a lower APR always the cheaper loan?

Over the same length of time, yes. Over different lengths, compare the total of payments as well.

Does asking for less lower the cost?

Usually. The finance charge grows with the amount and the time, so borrowing only what the gap needs is the simplest saving available.

Can the lender change the numbers after I sign?

Not the agreed amount, rate or schedule. Fees for late or returned payments apply only if those events happen, and they must be listed in the agreement.
