Loan-to-Value (LTV) is one of the most important numbers in the mortgage industry. It measures how much you are borrowing compared to how much your property is worth. Lenders use LTV to decide interest rates, mortgage insurance requirements, and approval decisions. In 2026, understanding LTV helps borrowers make smarter decisions about down payments, refinancing, and home equity products.

The LTV Formula
LTV is calculated with a simple formula: divide your loan amount by your property’s value (or purchase price, whichever is lower). Multiply the result by 100 to get a percentage.
LTV = (Loan Amount ÷ Property Value) × 100
For example, if you buy a $400,000 home with a $320,000 loan, your LTV is 80% ($320,000 ÷ $400,000 = 0.80 = 80%). If you put down $80,000 (20%), your LTV is 80%. Higher down payments mean lower LTV.
Combined Loan-to-Value (CLTV)
Combined Loan-to-Value (CLTV) adds all loans secured by the property. If you have a first mortgage and a second mortgage (like a HELOC or home equity loan), CLTV combines them.
CLTV = (First Mortgage + Second Mortgage) ÷ Property Value × 100
For example, if your home is worth $500,000 with a $300,000 first mortgage and a $50,000 HELOC, your CLTV is 70% ($350,000 ÷ $500,000). Lenders often care more about CLTV than just first-mortgage LTV.
Why LTV Matters to Lenders
Lower LTV means less risk for the lender. A borrower with 20% equity has “skin in the game” and is less likely to default. If the lender has to foreclose, they can sell the property and recover the loan even if prices drop somewhat.
Higher LTV means more risk for the lender. A borrower with only 5% equity could easily end up underwater if prices decline. Lenders offset this risk with higher rates, mortgage insurance requirements, or tighter credit standards.
LTV Rules by Loan Type in 2026
Different loan programs allow different maximum LTVs:
- Conventional Purchase: Up to 97% LTV for first-time buyers with mortgage insurance
- Conventional without PMI: 80% LTV maximum to avoid PMI
- FHA Purchase: 96.5% LTV maximum (3.5% down)
- VA Purchase: 100% LTV allowed (no down payment)
- USDA Purchase: 100% LTV allowed (no down payment)
- FHA Cash-Out Refinance: 80% LTV maximum (per HUD Mortgagee Letter 2019-11)
- VA Cash-Out Refinance: 100% LTV allowed
- Conventional Cash-Out: 80% LTV maximum on primary residence
- HELOC: 85-90% CLTV maximum on primary residence
LTV and Mortgage Insurance
LTV determines whether you need mortgage insurance and how much you pay. On conventional loans, LTV above 80% triggers Private Mortgage Insurance (PMI). PMI typically costs 0.5% to 1.5% of the loan amount annually. Once your LTV drops below 78%, federal law allows PMI cancellation on many loans (per the Homeowners Protection Act).
FHA loans require Mortgage Insurance Premium (MIP) for the full loan term in most cases regardless of LTV. VA loans never require monthly mortgage insurance regardless of LTV. Compare specific requirements via the FHA down payment guide for detailed FHA-specific LTV rules.
LTV and Interest Rates
LTV directly affects your interest rate. Lower LTV typically gets you better rates. The rate difference between 80% LTV and 95% LTV can be 0.25% to 0.75%. Over a 30-year mortgage, this can add up to tens of thousands of dollars.
Following the September 16, 2026 Federal Reserve rate hike, LTV impact on rates became more pronounced. Lenders view higher-LTV loans as riskier in an uncertain rate environment. Borrowers with 20%+ down payments often get significantly better pricing than those with minimum down payments.
Frequently Asked Questions
What is a good LTV ratio for a mortgage?
An 80% LTV is generally considered the “sweet spot” for conventional mortgages because it eliminates the need for Private Mortgage Insurance (PMI). Anything below 80% LTV is considered low-risk by lenders and typically qualifies for the best rates. LTV above 95% is considered high-risk and requires mortgage insurance plus higher interest rates. First-time buyers often start with higher LTVs (95-97%) and reduce over time through payments and appreciation. FHA and VA borrowers routinely have LTVs of 96.5% and 100% respectively.
How do I calculate my LTV?
Divide your total loan amount by your property’s appraised value (or purchase price, whichever is lower). Multiply by 100 for the percentage. On a $250,000 loan against a $300,000 property, LTV is 83.3% ($250,000 ÷ $300,000 = 0.833). For refinances or home equity products, use current appraised value. For combined LTV (CLTV), add all mortgage debt against the property. Online mortgage calculators can help with the math, but the formula is simple enough to do manually.
Can I lower my LTV to remove PMI?
Yes. You can lower your LTV through several methods. Make extra principal payments to reduce your loan balance faster. Wait for property appreciation to increase your home’s value. Renovate or improve the property to boost value. Request a new appraisal after significant improvements or 2+ years of market appreciation. Under the Homeowners Protection Act, lenders must cancel PMI automatically when your LTV reaches 78% of original value. You can request cancellation earlier at 80% LTV.
Does LTV affect refinance rates?
Yes, significantly. Lower LTV borrowers get better refinance rates than higher LTV borrowers. The rate spread between 80% LTV and 95% LTV on a refinance can be 0.25% to 0.75%. Cash-out refinances have stricter LTV limits than rate-and-term refinances (typically 80% on conventional cash-out vs 95% on rate-and-term). FHA Cash-Out is limited to 80% LTV under HUD Mortgagee Letter 2019-11. Explore the complete FHA refinance guide for FHA-specific LTV rules.
