What is LTV? Loan-to-Value Ratio Explained

The loan-to-value ratio (LTV) is one of the key numbers that lenders use when reviewing a mortgage application. It compares your loan amount to the appraised value of the home.

For military borrowers, understanding LTV also means understanding how VA loans change the equation entirely. Keep reading to learn how LTV works, why it matters, and why VA loans follow different rules.

Main Takeaways of LTV

• The loan-to-value ratio, or LTV, measures how much of an asset's value is being financed.
• Lower LTV signals less lender risk, which often translates to better rates and terms for the borrower.
• LTV comes into play across home purchases, refinancing, HELOCs, and auto loans.
• While conventional loans typically require PMI when the LTV exceeds 80%, VA loans avoid PMI entirely, regardless of LTV level.
• When multiple loans are secured by the same property, lenders calculate CLTV— combined loan-to-value—instead.

Loan-to-Value Ratio Meaning

LTV, or loan-to-value ratio, is the number that shows how much of an asset’s value is covered by a loan versus how much the borrower is paying out of pocket.

In the context of a mortgage, lenders compare the loan amount to the home’s appraised value. The same logic applies to auto financing, where the loan is measured next to the vehicle's value. Whenever an asset secures a loan, LTV helps lenders judge how risky the loan is.

When your LTV is low, you own more of the asset outright and have less loan to repay. When your LTV is high, it is the opposite: you own less of the asset and have more loan to repay. High LTV also usually means greater risk for the lender because the borrower has less equity.

The LTV Formula: How to Calculate Loan-to-Value

To calculate LTV, you need to know the amount of money you are borrowing (the loan amount) and the appraised value of the asset.

LTV = (Loan Amount ÷ Appraised Value) x 100

Example: How to Calculate LTV When Buying a Home

Imagine you are buying a home worth $325,000, and you are making a $65,000 down payment. That means, in total, you are borrowing $260,000. How it works:

• STEP 1: Identify your loan amount.

$325,000 - $65,000 = $260,000

• STEP 2: Divide the loan amount by the appraised value.

$260,000 ÷ $325,000 = 0.80

• STEP 3: Multiply by 100 to express LTV as a percentage.

0.80 x 100 = 80% LTV

What Do LTV Percentages Mean?

An LTV of 80% or lower is ideal for conventional loans. At or below that threshold, borrowers typically can sidestep private mortgage insurance (PMI). PMI is an extra monthly fee that protects the lender if the borrower defaults on the loan.

But for eligible service members and veterans using VA home loans, the rules are quite different. VA loans don't require PMI at any LTV level—even if you have a 100% LTV (as long as the home appraises for at least the agreed-upon purchase price).

That means a qualified VA loan borrower could potentially purchase a home with no down payment and no PMI obligation. This is not an option with conventional loans.

Keep in mind that VA financing is still capped at the appraised value. If the appraisal comes in below the purchase price, the VA loan can only cover the appraised amount. The difference must either be paid in cash by the buyer or renegotiated with the seller.

The Relationship Between LTV and Mortgage Rates

LTV can influence more than just PMI requirements—it also affects the rates that lenders offer. Borrowers with lower LTV ratios are generally seen as lower risk, which means they can receive more favorable loan terms.

For conventional loans, once LTV exceeds 80%, lenders see the loan as riskier. As a result, the interest rate may be higher to account for that added risk. Over the life of a 30-year mortgage, even a modest rate increase adds up to thousands of dollars in additional interest paid.

However, VA loans often carry competitive interest rates relative to conventional options. Combining this rate advantage with the absence of PMI, the overall cost profile of a VA loan can look very different from a conventional loan at a similar LTV.

How LTV Shifts Over Time and Why it Matters for Refinancing

LTV is not a fixed number. If your home’s value has increased since you purchased it, your LTV may have improved—even without a dramatic change in your loan balance.

In the example from before, we originally borrowed $260,000 on a home worth $325,000, resulting in an 80% LTV. If the home appraises for $375,000 in the future while the loan balance remains at $260,000, the LTV falls to roughly 69%. That shift may open the door to better refinancing terms or access to equity you didn't have before.

For VA borrowers, refinancing has a few distinct advantages. A VA cash-out refinance can go up to the full appraised value of the home—a higher ceiling than most conventional cash-out programs.

And for borrowers looking to reduce the rate on an existing VA loan, the Interest Rate Reduction Refinance Loan (IRRRL) often doesn't require a new appraisal, which means LTV is even less of a factor in that process.

CLTV for More Than One Loan

Some borrowers have more than one loan on the same property. When that happens, lenders don’t look at the LTV of each loan separately. Instead, they use a different calculation called the combined loan-to-value ratio, or CLTV.

CLTV = (Total Loan Balances ÷ Appraised Value) x 100

This situation is most common when it comes to a HELOC, or home equity line of credit. When applying for a HELOC, the lender doesn’t evaluate the new credit line by itself. They:

• Take your current mortgage balance
• Add the amount you want to borrow through the HELOC
• Compare that total to your home’s current appraised value

According to Experian, most lenders limit CLTV for HELOCs at around 85%, though the specific limit varies by lender and program.

For many VA borrowers, a VA cash-out refinance is often a better path than a HELOC for accessing home equity—since it replaces the existing loan rather than adding another one.

Vehicle Loans and LTV

LTV applies to auto financing as well, though the specifics play out a bit differently from real estate. Because vehicles lose value so quickly, auto loan LTV can shift much faster than it does with property.

When a car’s market value drops below the remaining loan balance—a situation sometimes referred to as being "underwater"—the borrower owes more money than the asset is even worth. That gap becomes a real problem if the car is totaled or if the owner needs to sell before the loan is fully paid off.

LTV vs. DTI: What is the Difference?

In mortgage underwriting, LTV isn’t the only factor at play. Another common measurement used is the DTI, or debt-to-income ratio. But how do LTV and DTI compare?

• LTV measures how much of the asset's value is covered by the loan.
• DTI measures how much of your monthly income goes toward debt payments.

Lenders look at both figures together because neither one tells the complete story alone. A high DTI with a strong LTV, or vice versa, can affect approval and terms in different ways.

Frequently Asked Questions: LTV Loan-to-Value

What does LTV mean on a mortgage?

LTV, or loan-to-value ratio, compares your loan amount to the appraised value of the home, expressed as a percentage. It's one of the key figures that lenders use to evaluate borrower risk and determine loan terms.

How do you calculate loan-to-value ratio?

Divide your loan amount by the appraised value of the property, then multiply by 100. A $260,000 loan on a $325,000 home would result in an LTV of 80%.

Do VA loans have LTV limits?

VA purchase loans can finance up to the entire appraised value of the home, making 100% LTV possible for eligible borrowers. However, VA financing is capped at the appraised value, not the purchase price. So if the home appraises for less than the purchase price, the borrower will need to make up the difference in another way.

Do VA loans require PMI?

No. VA loans do not require private mortgage insurance at any LTV level, which is one of the biggest financial advantages of VA loan eligibility compared to conventional financing. A VA funding fee may apply.

What is a good LTV ratio for a conventional mortgage?

80% or lower is the standard target for conventional loans. At that threshold, borrowers typically avoid PMI and may qualify for more favorable rates.

What is the difference between LTV and CLTV?

LTV measures a single loan against an asset's value. CLTV combines all loans secured by the same property—commonly used when evaluating HELOCs or second mortgages alongside a primary loan.

Can I refinance a VA loan if my LTV is high?

The VA's IRRRL program—designed to reduce the rate on an existing VA loan—often doesn't require a new appraisal, which means a high LTV isn’t as much of a barrier. With a VA cash-out refi, borrowers can refinance up to 100% of the home’s appraised value, which is a higher ceiling than most conventional programs allow.

Does LTV affect auto loans too?

Yes. Auto loan LTV compares the loan balance to the vehicle's current value. Because vehicles depreciate over time, LTV on auto loans can shift more quickly than LTV on real estate.
