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:
- LTV ≤ 60% — Excellent. Best available rates. No PMI. Strong refinancing position.
- LTV 61%–80% — Good. No PMI required on conventional loans. Competitive rates.
- LTV 81%–90% — Moderate risk. PMI required. Rates slightly higher.
- LTV 91%–95% — High risk. PMI required. Limited lender options. Rates higher.
- LTV > 95% — Very high risk. Only specialized programs (VA, USDA, FHA). MIP required.
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.
