Summary:
Loan-to-value (LTV) is a ratio that compares your loan amount to the appraised value of an asset, typically a home.
Lenders use LTV to assess the risk of lending; a lower LTV means you’ve put down a larger down payment and the lender is taking less risk.
- Calculation: Loan amount divided by property value, expressed as a percentage.
- Impact on borrowing: Lower LTV ratios qualify for better rates and terms; higher LTV ratios may require private mortgage insurance (PMI).
- Typical range: Most conventional loans require an LTV of 80% or lower; FHA loans may accept up to 96.5%.

What Is Loan-to-Value (LTV)?
Loan-to-value (LTV) is a financial metric that expresses the amount you’re borrowing as a percentage of the property’s appraised value. It answers the fundamental question lenders ask: “How much of this asset am I actually financing?”
If you’re buying a $300,000 home and putting down $60,000 (20%), your loan amount is $240,000, which equals an 80% LTV. This ratio is central to mortgage underwriting and determines whether you’ll be approved, at what rate, and whether you’ll need additional insurance.
How to Calculate LTV
The calculation is simple: divide the loan amount by the property’s appraised value, then multiply by 100 to express it as a percentage.
LTV = (Loan Amount / Property Appraised Value) × 100
Example: If you’re borrowing $240,000 for a $300,000 home, your LTV is ($240,000 / $300,000) × 100 = 80%. The remaining 20% is your equity (down payment).
LTV and Mortgage Qualification
Lenders view LTV as a proxy for risk. A borrower with an 80% LTV has 20% equity immediately; if property values fall or the borrower defaults, the lender can recover most of their investment through a sale. Conversely, a borrower with a 95% LTV has only 5% equity and poses significantly higher risk.
Conventional mortgages typically require an LTV of 80% or lower to avoid private mortgage insurance (PMI). FHA loans and other government-backed loan types accept higher LTVs, though they come with their own requirements and costs.
LTV Thresholds and Loan Terms
Most lenders have distinct pricing and requirements at different LTV tiers. Each loan program sets its own maximum LTV, and understanding where you fall within those tiers helps you plan your down payment strategically.
| LTV Range | Down Payment | Typical Requirements |
|---|---|---|
| 60%–75% | 25%–40% | Best rates, no PMI, minimal documentation |
| 75%–80% | 20%–25% | Competitive rates, no PMI, standard underwriting |
| 80%–90% | 10%–20% | PMI required, higher rates, stricter qualification |
| 90%–95% | 5%–10% | Higher PMI costs, elevated rates, extensive verification |
| 95%+ | Less than 5% | FHA or specialized loans, highest costs |
Private Mortgage Insurance and LTV
When your LTV exceeds 80%, lenders typically require private mortgage insurance (PMI). PMI protects the lender if you default; you pay the premium as part of your monthly mortgage payment. According to the Federal Home Loan Mortgage Corporation (Freddie Mac), PMI costs range from 0.3% to 1.5% of your loan amount annually, depending on your credit score and LTV.
The good news: once your LTV drops to 80% through refinancing or principal paydown, you can request PMI cancellation. This can save thousands in insurance premiums over your loan term.
How Appraisals Affect LTV
Your LTV is based on the property’s appraised value, not the purchase price. If the appraised value comes in lower than the purchase price, your LTV may increase unexpectedly. For example, if you agreed to pay $300,000 but the appraisal is $280,000 and you’re borrowing $240,000, your LTV becomes 85.7%—higher than anticipated.
This scenario may trigger PMI requirements or loan denial. Before making a pre-approval final, lenders confirm the appraised value to validate your LTV calculations.
Pro Tip
If you’re buying a home and your down payment would result in an LTV above 80%, consider waiting to accumulate a larger down payment or increase it to reach the 80% threshold. The savings from avoiding PMI can exceed $10,000–$20,000 over the life of your loan.
LTV and Interest Rates
Your LTV directly influences the interest rate you’ll be offered. Borrowers with lower LTVs (more equity) represent less risk and qualify for better rates. A borrower with a 60% LTV might receive rates 0.25%–0.5% lower than one with a 90% LTV.
Over a 30-year mortgage, this seemingly small difference compounds into tens of thousands of dollars in total interest paid. According to the SuperMoney Mortgage Industry Study, borrowers optimizing their down payments to achieve favorable LTV ratios save an average of 15–20% in total loan costs compared to high-LTV borrowers.
LTV in Refinancing
When you refinance an existing mortgage, your LTV is recalculated based on the current property value, not the original purchase price. If your home has appreciated, your LTV drops, potentially qualifying you for better rates and allowing cash-out refinancing.
Conversely, if home values decline, your LTV may increase, limiting refinancing options or requiring you to bring cash to the table (pay down the loan) to reduce LTV to acceptable levels.
LTV in Different Loan Types
Different loan programs have different LTV limits. Conventional mortgages typically cap out at 97% LTV with compensating factors, FHA loans accept up to 96.5%, and VA loans (for eligible veterans) can be 100% LTV. Understanding these parameters helps you choose the right loan type for your financial situation.
USDA loans for rural properties also have specific LTV requirements, and debt-to-income ratio becomes increasingly important at higher LTVs across all programs.
Good to know: LTV is one of several risk factors lenders evaluate. Even with a favorable LTV, you still need a good credit score, stable income, and a reasonable debt-to-income ratio to qualify for a mortgage. Conversely, a poor credit score or high existing debt can disqualify you even with a low LTV.
Strategic Down Payment Planning
Understanding LTV empowers you to make smarter down payment decisions. If you’re deciding between a 10%, 15%, or 20% down payment, calculating your resulting LTV and comparing mortgage terms helps you find the optimal balance between affordability and total cost.
Some borrowers benefit from putting down as little as 5% and investing the difference; others prioritize reaching 20% down to eliminate PMI entirely. Your financial circumstances, risk tolerance, and long-term plans should guide this decision.

Frequently Asked Questions
What’s a good LTV ratio?
An LTV of 80% or lower is generally considered ideal because you avoid PMI and qualify for better rates. However, your specific situation determines whether this is achievable. First-time homebuyers often start with 90%–95% LTV and improve through principal paydown over time.
Can I get a mortgage with a 95% LTV?
Yes, but you’ll face higher rates, PMI requirements, and stricter qualification criteria. FHA loans and some conventional lenders accept 95% LTV with compensating factors like excellent credit scores or larger cash reserves.
How does my LTV change over time?
As you make mortgage payments, your loan balance decreases, lowering your LTV. Additionally, if your home appreciates in value, your LTV also decreases. Both factors eventually bring you to 80% LTV, at which point you can request PMI cancellation.
Does LTV affect my property taxes or insurance?
LTV doesn’t directly affect property taxes or homeowners insurance. However, if you have PMI, it adds to your monthly payment. Property taxes are based on assessed value, and insurance is based on replacement cost—both independent of your LTV.
What if my home’s value declines and my LTV exceeds 100%?
This is called being “underwater” or having negative equity. You owe more than the home is worth, which complicates selling, refinancing, or accessing home equity. You’re still obligated to pay the full loan amount.
Key takeaways
- Loan-to-value (LTV) compares your loan amount to the property’s appraised value, expressed as a percentage.
- Lower LTV ratios (below 80%) qualify for better interest rates and eliminate the need for private mortgage insurance (PMI).
- Lenders use LTV as a primary risk assessment tool; your LTV heavily influences approval odds, rates, and required insurance.
- Strategic down payment planning can optimize your LTV, potentially saving tens of thousands in interest and PMI costs over your loan term.
- As you pay down principal and property values appreciate, your LTV improves, eventually allowing PMI cancellation.
When shopping for a mortgage, always calculate your potential LTV and ask lenders how it affects your rate and terms. Comparing offers across different down payment scenarios helps you find the most cost-effective path to homeownership. Review the mortgage reviews to find lenders that clearly explain LTV impact and offer competitive pricing at your target LTV.
