Auto Loan Rates for a 600 Credit Score in New Hampshire (2026)
A 600 credit score (Subprime, 580-619 FICO) qualifies for roughly 11.2% APR on auto loans in New Hampshire. On a $30K vehicle financed for 60 months, that's $655/month — with $9,300 going to interest over the life of the loan.
Monthly Payments by Loan Amount
Here's what you'd pay each month at 11.2% APR for different loan amounts and terms. The 60-month column is highlighted because it's the most common choice — long enough to keep payments manageable, short enough that you're not drowning in interest.
| Loan Amount | 36 mo | 48 mo | 60 mo | 72 mo | 84 mo |
|---|---|---|---|---|---|
| $15,000 | $493/mo | $389/mo | $328/mo | $287/mo | $258/mo |
| $20,000 | $657/mo | $519/mo | $437/mo | $383/mo | $345/mo |
| $25,000 | $821/mo | $649/mo | $546/mo | $478/mo | $431/mo |

The Term Length Trade-off: Monthly Savings vs. Interest Paid
Stretching your loan from 60 to 84 months drops your payment by $138/month. Sounds great — until you realize you're paying $4,128 more in total interest. Here's the full picture on a $30,000 loan at 11.2%:
| Loan Term | Monthly Payment | Total Interest Paid | Total Cost |
|---|---|---|---|
| 36 months (3 years) | $985/mo | $5,460 | $35,460 |
| 48 months (4 years) | $778/mo | $7,344 | $37,344 |
| 60 months (5 years) | $655/mo | $9,300 | $39,300 |
| 72 months (6 years) | $574/mo | $11,328 | $41,328 |
| 84 months (7 years) | $517/mo | $13,428 | $43,428 |
The 36-month option costs the most per month but saves you the most in interest. If you can swing it, the shorter term is almost always the better financial move — you pay off the car faster and spend less overall.
What Other Credit Scores Pay
With a 600 score, you're paying $6,900 more in interest over 5 years than someone with an 800 score — on the exact same car, from the exact same dealer. That's the credit score penalty in dollar terms.
| Credit Score | Lender Category | APR | Monthly ($30K/60mo) | Total Interest |
|---|---|---|---|---|
| 500 (300-579) | Deep Subprime | 15.5% | $722/mo | $13,320 |
| 600 (580-619) | Subprime | 11.2% | $655/mo | $9,300 |
| 650 (620-659) | Near Prime | 8.5% | $615/mo | $6,900 |
| 700 (660-719) | Prime | 5.8% | $577/mo | $4,620 |
| 750 (720-779) | Super Prime | 4.2% | $555/mo | $3,300 |
| 800 (780+) | Exceptional | 3.1% | $540/mo | $2,400 |
Potential Savings: $6,900
That's how much you'd save on a $30K loan by improving your credit from 600 to 800. Even moving up one tier could save you $2,400.
Where to Get the Best Rate in New Hampshire
Not all lenders are created equal, especially for subprime borrowers. Here's the pecking order for New Hampshire:
New Hampshire Credit Unions
10.0–10.9%Almost always the best rates. Not-for-profit, so they pass savings to members. Most require membership (usually free or $5-25 to join). Check with your local CU first.
Online Lenders (Capital One, LightStream)
10.7–11.5%Competitive rates with fast pre-approval (minutes, not days). Capital One Auto Navigator lets you see your rate without a hard credit pull. LightStream requires good credit but offers some of the lowest rates around.
Banks (Chase, BOA, Wells Fargo)
11.2–12.0%Standard rates — nothing special, but convenient if you already bank there. Some offer a 0.25-0.5% relationship discount for existing customers with checking/savings accounts.
Dealership Financing (F&I Office)
11.7–13.7%Usually the most expensive option. Dealers often mark up the rate by 1-2% and keep the difference as profit. Exception: manufacturer-subsidized 0% or low-APR promos (but these usually require 720+ credit).
Buy Here Pay Here Lots
18–29%Last resort. These lots don't really care about your credit score because the rates are astronomical for everyone. Only consider this if you cannot qualify anywhere else and absolutely need a car.
