How Loan-to-Value Ratio Is Calculated

Loan-to-Value (LTV) is one of the most important metrics in mortgage lending. It measures what percentage of a property's value is financed by debt. Lenders use LTV to assess risk: the higher the LTV, the less equity the borrower has and the greater the chance of loss if the borrower defaults. Based on standards set by Fannie Mae, Freddie Mac, and major US mortgage lenders, LTV is calculated as follows:

LTV Formula

LTV (%) = (Loan Amount / Property Value) × 100

Equity Amount = Property Value − Loan Amount

Equity (%) = 100 − LTV (%)

  • Loan Amount — current outstanding mortgage balance
  • Property Value — current appraised or market value of the property
  • Equity — the portion of the property you truly own outright
  • 80% LTV threshold — the standard cutoff for avoiding PMI on conventional loans

LTV Thresholds and What They Mean for Borrowers

Different LTV levels trigger different lender requirements and interest rates. Here are the key thresholds used by conventional US mortgage lenders as of 2026:

Note: FHA loans require Mortgage Insurance Premium (MIP) regardless of LTV. VA and USDA loans have no PMI requirement at all. Jumbo loans typically require LTV ≤ 80%.

How to Improve Your LTV Ratio

There are two ways to reduce your LTV: increase your property value or decrease your loan balance. Making extra mortgage payments reduces principal faster (use our Mortgage Overpayment Calculator to model this). Rising property values increase your equity automatically — in strong markets, homeowners can go from 90% to 80% LTV purely through appreciation. Once your LTV reaches 80% on a conventional loan, you can request PMI cancellation in writing under the Homeowners Protection Act of 1998. The lender must cancel it automatically when LTV reaches 78% based on the original payment schedule. Last updated: April 2026.

Frequently Asked Questions

What is loan-to-value (LTV) ratio?

LTV ratio is the percentage of a property's value that is financed by a mortgage loan. It is calculated as: LTV = (Loan Amount / Property Value) × 100. An LTV of 80% means you borrowed 80% of the home's value and own 20% as equity.

What LTV ratio is required to avoid PMI?

Most conventional lenders require an LTV of 80% or lower to waive Private Mortgage Insurance (PMI). If your LTV is above 80%, you will typically pay PMI until your loan balance drops below 80% of the original appraised value. FHA loans have different rules and require MIP regardless of LTV.

What is a good LTV ratio for a mortgage?

80% or below is considered good — you avoid PMI and qualify for better interest rates. 60% or below is excellent and may unlock the best rates. Above 90% is high-risk and usually requires mortgage insurance. Above 97% is very high-risk and only available for specialized loan programs.

How does LTV affect my mortgage interest rate?

Lower LTV ratios signal less risk to lenders, which typically means lower interest rates. Moving from a 95% LTV to 80% LTV can save 0.25%–0.75% in annual interest rate, which adds up to thousands of dollars over the life of a 30-year mortgage.
