Loan-to-value (LTV) is the loan amount divided by the vehicle's value, expressed as a percentage. An LTV below 80% is excellent; above 100% (owing more than the car is worth) is called being 'underwater' or in 'negative equity.' Lenders typically cap LTV at 100–130% for new cars and 100–115% for used cars. A higher LTV means higher risk for the lender — which translates to a higher interest rate, stricter approval, or outright decline.
LTV thresholds and their effects
| LTV | What it means | Lender's view | Your likely rate impact |
|---|---|---|---|
| Below 80% | Large down payment; significant equity from day 1 | Excellent — minimal risk | Best rates available |
| 80–90% | Standard down payment | Good — comfortable buffer | Competitive rates |
| 90–100% | Small or no down payment | Acceptable — limited buffer | Near-standard rates |
| 100–115% | Financing fees, tax, warranty rolled in | Elevated risk; many lenders still approve | Higher rate; stricter terms |
| Above 115–130% | Negative equity from another vehicle rolled in | High risk; limited lenders | Premium rate or decline |
| Above 130% | Severely underwater | Most lenders decline | Specialist/subprime only |
Calculating your LTV
The formula is straightforward: divide the loan amount by the vehicle's market value, then multiply by 100.
Example: you want to borrow $22,000 to buy a car with a market value of $25,000. LTV = (22,000 ÷ 25,000) × 100 = 88%. That is a comfortable LTV for most lenders.
The 'value' the lender uses is not necessarily the sticker price — it is typically the trade or retail value from a guide like Kelley Blue Book (US), CAP/Glass's (UK), or manufacturer book values (India). A car priced above its book value gives you a higher LTV than you might expect.
Why LTV matters more than you think
A car loses value the moment you drive it off the lot — typically 15–25% in the first year for a new car. If you financed 100% of the purchase price with no down payment, you could owe $5,000–$8,000 more than the car is worth within 12 months. This is negative equity, and it creates two serious problems: you cannot trade or sell without covering the shortfall out of pocket, and if the car is written off, your insurance payout may not cover the full loan balance.
How down payments affect LTV
- A 10% down payment on a $30,000 car ($3,000 down) brings LTV to 90%.
- A 20% down payment ($6,000 down) brings LTV to 80% — the threshold most lenders consider comfortable.
- Rolling in negative equity from a trade-in pushes LTV above 100% before you start.
What lenders do with LTV
Lenders use LTV as one of three primary risk factors alongside credit score and DTI. The interaction matters: a borrower with a 750 credit score and 110% LTV may still get approved at a competitive rate. A borrower with a 580 score and 115% LTV will face either a decline or a punishing rate because both risk factors are elevated simultaneously.
Some lenders publish their LTV caps openly; others determine them case by case. Common limits in 2026: 100–115% for prime borrowers on new cars; 100–110% for used cars; 80–100% for vehicles over 5 years old.
How to improve your LTV
- Increase your down payment. Even an extra $1,000–$2,000 meaningfully changes the risk picture.
- Choose a car with strong residual value. Brands with lower depreciation (Toyota, Honda, certain SUV segments) start your LTV in a better position.
- Pay off negative equity before trading in. Rolling negative equity from a previous car into a new loan compounds the problem.
- Consider GAP insurance if you must finance above 90% LTV — it covers the difference between the insurance payout and your loan balance if the car is totalled.
- Negotiate the car price. Paying below book value automatically lowers your LTV without touching the loan amount.
If your LTV is above 100%, GAP (Guaranteed Asset Protection) insurance is worth serious consideration. It costs £100–£300 in the UK or $200–$700 in the US typically, and covers the 'gap' between what insurance pays out and what you owe if the car is written off or stolen. Buy it from an insurer or standalone provider, not through the dealer — dealer-sold GAP is frequently significantly overpriced.
