What is Loan-to-Value (LTV)?
Loan-to-Value (LTV) is the ratio of a loan balance to the underlying asset's appraised value, expressed as a percentage. For a US mortgage it equals the loan amount divided by the lower of purchase price or appraised value. Higher LTV signals more lender risk and typically means a higher rate, mandatory mortgage insurance, or both.
Detailed definition
LTV is the most-used risk metric in US secured lending. It measures how much of the asset's value the lender is financing; the inverse (1 minus LTV) is the borrower's equity cushion. The lower the LTV at origination, the larger the equity buffer the lender can claim in a default, so the lower the risk-adjusted rate. The metric applies anywhere there is collateral: residential mortgages, commercial real estate, auto loans, securities lending, and home equity products.
For a US home purchase the math is constrained: lenders use the lower of contract price or appraised value as the denominator, so a buyer who overpays cannot inflate the value side. Government-sponsored enterprise (Fannie Mae and Freddie Mac) underwriting rules set the headline LTV thresholds that drive most US conforming loan pricing. FHA, VA, USDA, and jumbo programs each layer their own LTV rules on top of the conventional baseline. The Loan-Level Price Adjustment (LLPA) matrix published by Fannie Mae converts each LTV / FICO combination into a price add-on in points, which the lender then converts into a rate add-on.
LTV is dynamic. It moves as the borrower pays down principal (which falls predictably from the amortization schedule) and as the home's market value changes (which is volatile). When LTV drops, the borrower can usually drop PMI; when LTV rises (cash-out refinance, market decline), the borrower may face stricter terms on the next refinance or be unable to refinance at all. The "underwater" condition (LTV above 100 percent) was the central problem of the 2008 to 2012 US housing crisis.
Formula
LTV = Loan amount / Property value (basic formula) CLTV = (First mortgage + Second + HELOC drawn) / Property value HCLTV = (First mortgage + Second + HELOC limit) / Property value
- Loan amount = current principal balance (or origination balance for the "original LTV" number).
- Property value = lower of purchase price or appraised value at purchase; fresh appraised value at refinance.
- CLTV (combined LTV) sums all current liens. Used to cap second-lien borrowing (HELOC, home equity loan).
- HCLTV (HELOC CLTV) uses the HELOC's credit limit instead of its drawn balance, so it reflects the worst-case lien stack.
Worked example (2026 home purchase)
Suppose a 2026 buyer purchases a $500,000 home in Texas with a $50,000 down payment and a $450,000 conventional 30-year fixed mortgage. The appraisal comes in at $510,000.
- Purchase price: $500,000.
- Appraised value: $510,000.
- Denominator (lower of price or appraisal): $500,000.
- Loan amount: $450,000.
- LTV at origination: $450,000 / $500,000 = 90 percent.
- PMI required: yes (LTV exceeds 80 percent on a conventional loan). Estimated PMI 0.50 percent of loan amount per year = $2,250, about $187.50 per month.
- Path to PMI cancellation: reach 80 percent LTV by either paying down to $400,000 balance, having the home appraise at $562,500, or hitting the federal 78 percent automatic termination at $390,000 scheduled balance.
US LTV thresholds by loan program
| Loan program | Maximum LTV | Mortgage insurance | Notes |
|---|---|---|---|
| Conventional (Fannie / Freddie) | 97 percent (HomeReady / Home Possible); 95 percent for standard | PMI above 80 percent; auto-cancels at 78 percent | Best risk pricing at 60 percent or lower |
| FHA | 96.5 percent with 580+ FICO; 90 percent with 500 to 579 | MIP for life of loan unless 10 percent down (then 11 years) | Lower FICO floor than conventional |
| VA | 100 percent for eligible veterans | No monthly MI; one-time funding fee 1.25 to 3.30 percent | VA loan limit follows conforming limit |
| USDA Rural Development | 100 percent in eligible rural areas | Guarantee fee plus annual fee (lower than FHA MIP) | Income-limited program |
| Jumbo | Typically 80 to 90 percent; varies by lender | PMI or LPMI; some lenders offer no-MI jumbo at 80 percent LTV | Above conforming limit ($806,500 baseline in 2026) |
| HELOC / Home Equity Loan | CLTV capped at 80 to 90 percent typically | Not applicable | Second lien against the first mortgage |

Frequently asked questions
What is a good LTV ratio?
For a US mortgage, 80 percent or below is the standard threshold that avoids PMI on conventional loans and unlocks the best risk-adjusted rates. 60 percent LTV or lower gets the best advertised mortgage rates. For auto loans, anything under 110 percent LTV is reasonable; above that the loan is underwater the moment the car leaves the lot.
How is LTV calculated?
LTV = Loan amount / Property value x 100. For a purchase, lenders use the lower of purchase price or appraised value as the denominator. For a refinance, they use the new loan amount and a fresh appraised value. A $320,000 loan on a $400,000 home is 80 percent LTV; the same loan on a $355,000 home is 90.1 percent LTV.
What LTV triggers PMI?
Conventional loans require PMI above 80 percent LTV at origination, per Fannie Mae and Freddie Mac. Under federal law (Homeowners Protection Act) PMI is automatically terminated when the scheduled LTV reaches 78 percent of the original value, and can be cancelled on request at 80 percent. FHA loans carry MIP (mortgage insurance premium) regardless of LTV; VA loans require no monthly mortgage insurance even at 100 percent LTV.
Can my LTV change after I take the loan?
Yes. LTV changes whenever you pay down principal or the home's market value changes. Paying extra principal and home appreciation both lower LTV; a HELOC, cash-out refinance, or home depreciation raise it. Most lenders require a 2-year seasoning period before letting appreciation drive PMI cancellation; after 5 years it lowers to the standard 80 percent threshold from any appraised value.
What is combined LTV (CLTV)?
CLTV is the ratio of all liens against a property (first mortgage plus HELOC plus home equity loan) to the appraised value. Lenders cap CLTV around 90 to 95 percent on most conventional second-lien structures. HCLTV is a related metric that uses the HELOC's full credit limit rather than the drawn balance.
Does LTV affect my interest rate?
Yes. Lower LTV generally produces a lower rate because lender risk falls. The Fannie Mae Loan-Level Price Adjustment (LLPA) matrix is the official US conforming loan pricing grid: at the same FICO of 740, the LLPA gap between 60 percent LTV and 95 percent LTV can run 1.0 to 1.5 points in fee, which usually translates to 0.25 to 0.50 percentage points on the offered rate.
