The formula behind the payment
The payment on a fixed-rate loan is: amount × monthly rate ÷ (1 − (1 + monthly rate)−months). For $30,000 over 48 months at 7% APR the monthly rate is 0.5833%, which gives $718.39. Multiplying by 48 months gives $34,483 repaid in total, so the cost of borrowing is $4,483.
Should you borrow $30,000 over 4 years or a different term?
A longer term lowers the monthly payment but you pay interest for longer. At 7% APR, repaying $30,000 over 3 years costs $926.31 a month and $3,347 in interest, while 7 years costs $452.78 a month and $8,034 in interest. That is $4,686 more for the lower payment.

Interest versus capital: where your payments go
Early payments are mostly interest. In year 1 of this $30,000 loan, $1,887 of your $8,621 goes on interest and $6,734 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 $30,000 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 car loan, below about a third of your take-home pay. A $718.39 payment fits that guide if your monthly take-home pay is at least $2,155.
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 7 years to 3 years would save $4,686 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 7% over 4 years adds about $23.95 to the monthly payment.
