Loan size: $500
A $500 Loan, Worked Out
Five hundred dollars is where loan pricing gets strange: the interest is small in dollars, but flat fees and short terms can push the APR into triple digits. Here is what this size should cost and where the trap sits.

In one ring
At 15% APR over 12 months, $500 costs $45.13 a month and $41.55 in interest. Even at 28%, the most a federal credit union may charge on a payday alternative loan, a 12-month loan costs $79.04 in interest. A two-week payday loan with a $15 fee per $100 costs $75 and works out to an APR near 400%. At this size, the fee and the length of the loan matter more than the rate. These are worked examples with a fixed rate, equal monthly payments and no fees unless stated.
What $500 costs at different rates and terms
The table gives the monthly payment and, in brackets, the total interest on $500 at fixed rates, with equal monthly payments and no fees. These are worked examples from the standard amortization formula, not offers. Try your own rate in the payment by loan size calculator.
| APR | 6 months | 12 months |
|---|---|---|
| 15% | $87.02 ($22.10 interest) | $45.13 ($41.55) |
| 18% | $87.76 ($26.58) | $45.84 ($50.08) |
| 28% | $90.27 ($41.62) | $48.25 ($79.04) |
| 36% | $92.30 ($53.79) | $50.23 ($102.77) |
Every cell stays under $103 of interest. That is the point of an amortizing loan at a normal rate: even at 36% APR, a year of payments costs $102.77 in interest on $500. The products that cost far more at this size are the ones priced by fee rather than by rate.
How a small loan reaches a triple-digit APR
The APR turns any cost into a yearly rate. On a large, long loan, fees are spread over years. On $500 repaid in two weeks or a month, a flat fee that looks small in dollars becomes a very high APR. Worked examples:
- A two-week payday loan. A $15 fee per $100 borrowed is $75 on $500. Over 14 days that equals an APR of about 391%; the CFPB describes it as almost 400 percent.
- The same loan renewed. Pay only the $75 fee every two weeks for 12 weeks and you have paid $450 in fees and still owe the $500.
- A flat fee for one month. $25 on $500 repaid after one month is a 60% APR.
- A flat fee spread out. $30 on $500, repaid in three equal monthly payments of $176.67, is an APR of about 35.7%.
- A paycheck advance. A $5 fee for a fast transfer on a $100 advance repaid in 14 days works out to about 130% a year, even if the app does not call it interest.
Where a $500 loan comes from
Credit union PALs
Federal credit unions can make payday alternative loans of up to $2,000 at no more than 28% APR, with an application fee capped at $20. They must be repaid in installments, not in one lump sum.
Bank small-dollar loans
In 2020 the federal banking and credit union regulators issued joint principles that encourage supervised banks and credit unions to offer responsible small-dollar loans. Some banks offer small installment loans to existing checking customers, often for a flat fee; convert that fee to an APR before you compare.
Paycheck advance apps
Apps that advance part of your pay can help once, but subscription fees, fast-transfer fees and tips add up, and the advance comes out of your next paycheck. Repeated advances can leave each paycheck short. Use them with care.
Online lenders and finance companies
Some set minimum loan amounts above $500, and rates on small loans from lenders that approve weaker credit can be high. State law decides what a licensed lender may charge at this size.
Lendmira compares payday loan alternatives in detail, and TrustCedar sets a personal loan against a credit union PAL. If you are on active duty or a dependent, the Military Lending Act caps the all-in cost of most consumer loans at a 36% military annual percentage rate.
The PAL rules that shape a $500 loan
National Credit Union Administration rules set two versions of the payday alternative loan for federal credit unions. A $500 loan fits either one.
- PAL I: $200 to $1,000, repaid over one to six months; you must have been a member for at least one month.
- PAL II: up to $2,000, repaid over one to 12 months, with no waiting period after you join.
- Price: up to 28% APR, plus an application fee of no more than $20 that reflects the actual cost of processing.
- Limits: one PAL at a time, no more than three in a rolling six months, no rollovers, and every loan fully repaid in installments.
The $20 fee weighs more on a small loan. If it came out of a $500 PAL at 28% over 12 months, you would receive $480 and repay $48.25 a month, an effective cost of about 36.1% a year. Over six months the same fee lifts the effective cost to about 42.8%. This is a worked example, not the disclosed APR, which may leave an application fee out. A longer term spreads a fixed fee thinner.
Why 12 months can be the safer term
At 28% APR, $500 over six months costs $90.27 a month and $41.62 in interest. Over 12 months it costs $48.25 a month and $79.04. You pay about $37 more to cut the payment almost in half. If $90 a month would leave you short, the late fee or the second loan you take to cover it would cost more than that difference. A 12-month loan grows a single ring; the table follows it quarter by quarter.
| Months | Principal repaid | Interest paid | Balance at end |
|---|---|---|---|
| Months 1–3 | $112.34 | $32.42 | $387.66 |
| Months 4–6 | $120.39 | $24.37 | $267.27 |
| Months 7–9 | $129.01 | $15.74 | $138.26 |
| Months 10–12 | $138.26 | $6.50 | $0 |
Most of the interest falls in the first two quarters, so an extra payment early in the year saves the most. PALs must amortize fully, and NCUA rules let a federal credit union member repay a loan early on any business day without penalty (12 CFR 701.21(c)(6)).
Income and the size check
At $500, the debt-to-income test barely moves. The $45.13 payment at 15% over 12 months needs about $125 of gross monthly income on its own at a 36% limit. With a $1,200 rent payment and $400 of other monthly debts, the income needed rises from about $4,444 without the loan to about $4,570 with it. If you already sit near the limit, a lender may still say no; more often, small-loan decisions rest on your account history, recent pay and whether you have other short-term loans outstanding. The borrowing room calculator runs your numbers.
Fees and the right amount
If a lender deducts a 5% origination fee, a $500 loan puts $475 in your account. To receive $500, you would request about $526.32; the amount to request calculator does this gross-up. Borrow the bill, not a round number: if you need $320, a PAL I can start at $200, and every dollar you do not borrow is a dollar you do not repay with interest. Minimum and maximum loan amounts explains why some lenders will not go this small.
- Ask your credit union whether it offers a PAL and how long you must be a member.
- Get the APR and the dollar total of payments in writing for any small loan or advance.
- Pick the shortest term whose payment you can make in an ordinary month, not the shortest term on offer.
Questions people ask
How much is a $500 loan per month?
At 15% APR with no fees, $45.13 a month over 12 months or $87.02 over six. At 28%, the PAL ceiling, $48.25 over 12 months. These are worked examples, not offers.
What is the highest APR a credit union can charge on a payday alternative loan?
28%, plus an application fee of up to $20, under NCUA rules. Most other federal credit union loans are capped at 18% through September 10, 2027.
Is a paycheck advance app better than a $500 loan?
For a small gap you can repay from one paycheck, it can cost less in dollars. For $500 that you need several months to repay, an installment loan avoids a cycle of repeated advances. Convert every fee to an APR before you compare.
Can I get a $500 loan with bad credit?
Credit unions, banks with small-dollar programs and licensed lenders each set their own standards, and PALs often weigh membership and income heavily. Lendmira covers borrowing with bad credit.
