The formula behind the payment
The payment on a fixed-rate loan is: amount × monthly rate ÷ (1 − (1 + monthly rate)−months). For $15,000 over 36 months at 12% APR the monthly rate is 1.0000%, which gives $498.21. Multiplying by 36 months gives $17,936 repaid in total, so the cost of borrowing is $2,936.
Should you borrow $15,000 over 3 years or a different term?
A longer term lowers the monthly payment but you pay interest for longer. At 12% APR, repaying $15,000 over 2 years costs $706.10 a month and $1,946 in interest, while 5 years costs $333.67 a month and $5,020 in interest. That is $3,074 more for the lower payment.

Interest versus capital: where your payments go
Early payments are mostly interest. In year 1 of this $15,000 loan, $1,562 of your $5,979 goes on interest and $4,416 reduces what you owe. By the last year the split reverses, which is why paying off a loan early saves more in the early years than the later ones.

What happens if you overpay your $15,000 loan?
Paying a little extra each month cuts the balance faster, so less interest is charged. Check that your lender allows overpayments and whether there is a charge: many allow up to a set amount a year without one.

How to work out if the payment is affordable
A common check is to keep all debt repayments, including this personal loan, below about a third of your take-home pay. A $498.21 payment fits that guide if your monthly take-home pay is at least $1,495.
Also look at what happens if your income drops. Choose a payment you could still make for several months without borrowing again.
What to check before you sign
- Compare offers from banks, credit unions and online lenders. Prequalifying with a soft credit check does not affect your credit score.
- Ask about origination fees, which are taken from the loan amount and raise the true cost.
- Check for a prepayment penalty. Most lenders do not charge one, but some do.
- Credit unions often offer lower rates than banks for members with fair credit.
Ways to pay less interest
- Pick the shortest term whose monthly payment you can comfortably afford. Going from 5 years to 2 years would save $3,074 on this loan.
- Improve your credit score before you apply: pay bills on time, keep card balances low and dispute errors on your reports.
- Make extra payments when you can, as long as there is no penalty. Each extra payment cuts the balance that interest is charged on.
- Borrow only what you need: every extra $1,000 at 12% over 3 years adds about $33.21 to the monthly payment.
