Can I Get a $40,000 Car With a 600 Credit Score?

Written by JaredLast reviewed 2026-08-07

Can a 600 credit score get approved for a $40,000 car loan?

Not by itself. A 600 score doesn't qualify you for anything — it places you in the subprime pricing tier, 18.86% APR on used vehicles as of Q4 2025, and a lender still has to underwrite this specific loan against your income, down payment, and the vehicle's loan-to-value before it approves it. On a $40,000 vehicle, that underwriting is usually where the deal runs into trouble, not the credit pull.

It can be done. It usually shouldn't be, and the numbers below are why.

What would the payment actually be at a 600 score's rate?

Bigger than most buyers expect, and it barely moves with the standard down payment. Here's a $40,000 vehicle financed at 18.86% APR — the subprime-tier rate a 600 score lands in — after the canonical $1,000 to $2,500 down payment:

Rate: 18.86% APR, Experian's subprime-tier average for Q4 2025. Payments computed on the amount financed.

Even the cheapest-per-month version costs real money over time: 84 months at $1,000 down runs $839/mo, but it adds up to $31,516 in interest — more than three-quarters of the loan again, paid to the lender. The 60-month version at $1,000 down carries $21,521 in interest instead. Every dollar shaved off the monthly payment by stretching the term is bought with more interest, not less.

What income would a lender want to see to carry that payment?

More than most 600-score buyers can document. Take the 72-month, $1,000-down version — $909 a month — and run it against a typical 15% to 20% payment-to-income cap: it takes gross monthly income of $4,545 to $6,060, depending on where a specific lender sets the cap inside that range.

That's $54,540 to $72,720 a year, from one primary, provable source. It sits well above the $1,500 to $2,000 a month income floor most subprime programs are actually built around — a floor that supports a payment closer to $300 to $400. A 600 score does not change that income math; the rate is the same whether you finance $10,000 or $40,000.

Why doesn't the $1,000 to $2,500 down payment change much here?

Because $1,500 more cash is a small fraction of a $40,000 loan. Compare the two rows in the table above at 72 months: $1,000 down runs $909/mo; $2,500 down runs $874/mo. That's a $35-a-month difference for two and a half times the down payment.

The canonical down payment range does real work on a $12,000 or $15,000 loan, where it's 7% to 20% of the amount financed. On a $40,000 vehicle it's 2.5% to 6.25% — not enough to meaningfully shift the loan-to-value or the payment. A bigger down payment is the fix here, but it needs to be a bigger number than the standard range, not a payment inside it.

Why do lenders look at PTI and LTV instead of just the score?

Because the score describes your credit history, not whether this specific payment on this specific vehicle is provable and sustainable. Two separate ratios do that work:

• [Payment-to-income (PTI)](/glossary/payment-to-income-ratio/) caps the payment at roughly 15% to 20% of documented gross monthly income, regardless of the score.
• [Loan-to-value (LTV)](/glossary/loan-to-value/) caps how much a lender will advance against the vehicle's book value, and the cap tightens as the credit tier drops.

A $40,000 loan can clear the credit decision and still fail both of these, because both run on income and collateral, not on the three-digit number. See car loan income requirements for the income side in full.

What's the negative-equity risk on a loan this size?

Larger in dollars, even at an ordinary rate. About 30% of trade-ins carry negative equity, averaging roughly $7,100 — and a $40,000 loan stretched to 72 or 84 months pays down principal slowly in exactly the years the vehicle depreciates fastest, which is how that gap forms in the first place.

On a $15,000 car, being underwater by a few thousand dollars is a bad trade-in. On a $40,000 car financed at subprime rates over 7 years, the same depreciation curve applied to a much bigger balance means more total dollars owed on a car worth less than the loan for longer. See negative equity for the full mechanics of how that gap forms and what closes it.

What's a realistic price band at a 600 score instead?

Considerably smaller than $40,000, sized to the income floor rather than to the vehicle. Here's what a 60-month loan at 18.86% costs against the canonical $1,500 to $2,000 income floor, and against the $2,600 figure used elsewhere on this site:

Add the $1,000 to $2,500 down payment back on top of the financed amount and the realistic total price band lands around $13,000 to $17,500 — not $40,000. That's the number worth shopping against for most buyers at this score, and it's a wider, easier-to-find inventory than it might sound.

When can $40,000 actually work at a 600 score?

With a much larger down payment or trade equity than the canonical range, paired with income well above the floor. Put $10,000 down or in trade equity on a $40,000 vehicle and the amount financed drops to $30,000:

That's still meaningfully above the $1,500 to $2,000 floor this audience is usually working with, but it's a realistic file for a buyer with strong, documented income — a dual-income household, or a single higher earner — rather than a stretch. The score isn't what unlocks this version of the deal; the down payment and the income are.

The straightforward answer

A 600 score can sit on an approved $40,000 car loan, but almost always only when a large down payment or trade equity and well-above-floor income are already in place — and even then, it's worth asking whether that much car is the right call. At 18.86%, a $40,000 loan generates tens of thousands of dollars in interest before it generates a lower payment through a longer term, and it sets up exactly the kind of negative-equity position that's hardest to unwind later.

For most readers at this score, the honest move is sizing the vehicle to the $13,000 to $17,500 band above, not the score to the vehicle.
