The calculator is prefilled with an estimated 9.60% APR for a new-car loan at a 630 score (near prime tier). Enter your take-home pay and down payment; adjust anything, including the rate if you already have a quote.
A 630 credit score puts you in Experian's near-prime tier (601-660): mainstream lenders approve this range every day, and the average new-car loan near this score prices around 9.6%, with used cars around 14.2%. You are past the expensive part of the curve but not yet at the pricing lenders advertise.
The number to know at 630 is 661. Crossing into the prime tier cuts the average new-car rate by about a third. If you are within 20 or 30 points, a couple of months of low card balances before your application can genuinely change your quote.
| Credit tier | Avg new-car APR | Avg used-car APR |
|---|---|---|
| Super prime (781-850) | 4.6% | 6.8% |
| Prime (661-780) | 6.3% | 9.4% |
| Near prime (601-660) | 9.6% | 14.2% |
| Subprime (501-600) | 13.3% | 19.4% |
| Deep subprime (300-500) | 16.0% | 21.8% |

Take a buyer with $4,500 a month in take-home pay, $3,000 down, no trade-in, on a 60-month loan, keeping the payment at 10% of take-home ($450/month):
| Estimated new-car APR at 630 | 9.60% |
| Loan amount the payment supports | $21,377 |
| Car budget (sticker, after ~9% taxes and fees) | $22,400 |
| Total interest over 60 months | $5,623 |
| Same buyer with super-prime credit | $24,800 (interest $2,921) |
Near-prime is where rate shopping starts paying real money: quotes on the same borrower can vary by 2 points or more between lenders. Get at least three, and let the dealer beat your credit-union offer instead of anchoring on theirs.
Prime pricing starts at 661. Below-30% card utilization and no new credit applications in the 90 days before you apply are the fastest levers at this level. At super-prime rates the benchmark buyer above affords about $24,800 instead of $22,400, and pays about $45/month less in interest for the same loan size.
Rates step down at 601, 661, and 781. Pick your exact score, or use the main car affordability calculator if credit is not your constraint:
Cars are the smaller half of the credit question. See how much house you can afford with a 630 credit score, and what credit score you need to buy a house.
