What a $500 Loan Costs by Repayment Term
When you borrow $500, the repayment term changes two things at once, and they pull in opposite directions. A longer term lowers the monthly payment, which can make the loan feel more affordable. At the same time it raises the total interest you pay, because the balance stays outstanding for longer. The figures below hold the rate fixed at a 150% APR so you can see the trade-off clearly: the monthly payment drops from about $210 to about $83, while the total interest climbs from $130 to $491.
The cost by term, in full
These figures assume a $500 loan at a fixed 150% APR, repaid in equal monthly payments. The monthly payment falls as the term lengthens, but the interest column, the true price of the loan, moves the other way.
| Term | Monthly payment | Interest paid | Total repaid |
|---|---|---|---|
| 3 months | $210 | $130 | $630 |
| 6 months | $123 | $240 | $740 |
| 9 months | $96 | $361 | $861 |
| 12 months | $83 | $491 | $991 |
A smaller payment is not a cheaper loan. Stretching the same $500 from a 3-month term to a 12-month term nearly quadruples the interest, from $130 to $491, even though the monthly payment more than halves. Read the total repaid, not just the payment.
Why a longer term costs more
Interest is charged on the balance you still owe. Each month you carry the loan, more interest accrues, so holding a balance for 12 months instead of 3 means far more of these charges add up. A longer term spreads the same principal across more payments, which shrinks each one, but every extra month is another month of interest on what remains. At a 150% APR that effect is large, which is why the total nearly quadruples across the terms shown. The lower payment is real, but you are paying for the convenience with a much higher total cost.
How to keep the cost down
- Pick the shortest term you can afford. A shorter term raises the monthly payment but cuts the total interest. Choose the shortest schedule your budget can carry without strain.
- Compare the APR across lenders. The same request can draw very different rates, and a lower APR reduces the cost at every term.
- Borrow only what you need. A smaller principal means less interest on every payment, whatever the term.
- Look at cheaper alternatives first. A credit-union payday alternative loan (PAL), a lower-APR personal loan, a paycheck advance, or a payment plan with the biller can cost far less than a high-APR short-term loan.
- Avoid rolling the loan over. Renewing a short-term loan stacks new fees on top of the balance and is how a small loan becomes an expensive one.
Frequently asked questions
Does a longer term lower the monthly payment?
Yes. On a $500 loan at 150% APR, the payment falls from about $210 over 3 months to about $83 over 12 months. The trade-off is that you pay interest for longer, so the total interest rises from $130 to $491.
Why does a longer term cost more in total?
Interest accrues on the balance you still owe each month. More months with a balance outstanding means more interest, even though each payment is smaller. At 150% APR the total interest on a $500 loan nearly quadruples going from 3 months to 12 months.
Are there cheaper options than a high-APR short-term loan?
Often yes. A credit-union payday alternative loan, a lower-APR personal loan, a paycheck advance, or a payment plan with the biller can cost far less. Compare the APR and the total repaid before you borrow.
