What is Loan-to-Value Ratio?

The loan-to-value (LTV) ratio is a financial metric that compares the amount of a mortgage or loan to the appraised value of the property being purchased. Lenders use this ratio to assess the risk of extending credit. A lower LTV ratio indicates more equity in the property and less risk for the lender, while a higher LTV ratio suggests higher leverage and greater risk.

How to Calculate LTV Ratio

The loan-to-value ratio is calculated using the following formula:

LTV = (Loan Amount / Property Appraised Value) x 100

For example, if you are taking a mortgage of $240,000 on a property appraised at $300,000, your LTV ratio would be ($240,000 / $300,000) x 100 = 80%. This means you are financing 80% of the property's value and making a 20% down payment. An 80% LTV is the conventional threshold below which private mortgage insurance (PMI) is typically not required.

Using the Three Calculation Modes

Our LTV calculator offers three calculation modes to help you with different scenarios:

  • LTV Ratio: Calculate the loan-to-value percentage when you know the loan amount and property value.
  • Loan Amount: Find the maximum loan you can borrow based on a target LTV ratio and property value.
  • Property Value: Determine the minimum property value needed to achieve a target LTV ratio for a given loan amount.

Why LTV Matters

The loan-to-value ratio affects several aspects of your mortgage:

  • Interest Rates: A lower LTV typically qualifies for better interest rates since the lender takes on less risk.
  • PMI Requirements: Conventional loans with an LTV above 80% require private mortgage insurance, which adds $100-$300 or more to your monthly payment.
  • Loan Approval: Higher LTV ratios may face stricter approval criteria or require compensating factors like a higher credit score.
  • Refinancing: When refinancing, lenders evaluate your current LTV to determine eligibility and terms.

Frequently Asked Questions

What is a good loan-to-value ratio?

An LTV of 80% or lower is considered good for conventional loans, as it allows you to avoid PMI. For investment properties, lenders often require 75% or lower. Government-backed loans like FHA allow up to 96.5% LTV, while VA loans offer 100% LTV for eligible borrowers.

How does LTV affect my mortgage rate?

Higher LTV ratios mean higher risk for lenders, which results in higher interest rates. A borrower at 95% LTV may pay 0.25-0.50% more than someone at 80% LTV. Dropping below key thresholds (80%, 75%, 60%) often unlocks progressively better rate tiers.

What is the difference between LTV and CLTV?

LTV uses only the primary mortgage amount in the numerator. Combined LTV (CLTV) adds all liens including first mortgage, home equity loans, and HELOCs, then divides by the property value. A home worth $400,000 with a $280,000 first mortgage and $40,000 HELOC has an LTV of 70% but a CLTV of 80%.

Can my LTV ratio change after closing?

Yes. LTV decreases as you make principal payments and as the property appreciates in value. It can also increase if property values decline. To get an updated LTV for PMI removal or refinancing, you typically need a new appraisal to establish the current property value.

What LTV do I need to remove PMI?

Under federal law, lenders must automatically cancel PMI when your LTV reaches 78% based on the original amortization schedule. You can also request PMI removal when your LTV reaches 80%, either through making extra payments or if the property appreciates in value.
