What is an LTV Calculator?
An LTV calculator (Loan-to-Value calculator) is a mortgage tool that determines the ratio between your loan amount and property value, expressed as a percentage. This critical metric helps lenders assess mortgage risk and determines interest rates, PMI requirements, and loan approval likelihood.
This calculator helps with:
- PMI requirement determination - Know if you'll pay private mortgage insurance (LTV above 80%)
- Refinancing eligibility - Assess qualification for refinancing based on current home value
- Interest rate estimation - Lower LTV typically qualifies for better mortgage rates
- Equity tracking - Monitor how much equity you've built through payments and appreciation
- Down payment planning - Determine down payment needed to reach target LTV ratios
For calculating optimal down payment amounts to achieve target LTV ratios, use our down payment calculator to plan your home purchase savings strategy.
When evaluating gift of equity transactions that affect your LTV ratio, try our gift of equity calculator to determine equity contributions from family members.
To estimate your current home value for accurate LTV calculations, explore our home value calculator using comparable sales data.

How LTV Ratio Calculations Work
LTV ratio is calculated by dividing your loan amount by the property's appraised value, providing lenders with a standardized risk assessment metric.
The formula:
Equity Amount = Property Value - Loan Amount
Equity Percentage = 100 - LTV Ratio
PMI Required = LTV > 80% ? Yes : No
Where:
- Loan Amount - Total mortgage borrowed or remaining balance
- Property Value - Current market value or original purchase price
- Equity Amount - Your ownership stake in the property (value minus loan)
- PMI - Private mortgage insurance required when LTV exceeds 80%
Lower LTV ratios indicate less risk for lenders because you have more equity invested in the property. This translates to better interest rates, lower fees, and easier loan approval.
Key Concepts Explained
The critical benchmark for conventional mortgages. At 80% LTV or below, you avoid PMI and qualify for best rates. Above 80% requires mortgage insurance and may face higher interest rates due to increased lender risk.
LTV and equity are inversely related - as LTV decreases, equity increases. 80% LTV means 20% equity. Building equity through payments or appreciation lowers your LTV and increases financial flexibility for refinancing or selling.
Lenders offer tiered pricing based on LTV. Rates improve at 95%, 90%, 85%, and 80% thresholds. The difference between 95% LTV and 75% LTV can be 0.5-1% in interest rates, saving thousands over loan life.
Most refinancing requires 80% LTV or lower without PMI. Cash-out refinancing typically needs 75-80% LTV. If home values drop, high LTV may prevent refinancing even with good credit and income.

Benefits of Using This Calculator
- Avoid PMI surprises - Know upfront if you'll pay mortgage insurance or what down payment avoids it
- Plan refinancing timing - Track when equity buildup makes you eligible for better refinancing terms
- Estimate interest rates - Understand how your LTV affects mortgage rate quotes from lenders
- Monitor equity growth - Track home equity increases from payments and property appreciation over time
- Optimize down payments - Determine exact down payment needed to reach 80% LTV and avoid PMI
- Assess loan approval odds - Higher equity and lower LTV improve approval chances and loan terms
Factors That Affect Your Results
- Property value changes - Home appreciation lowers LTV while depreciation increases it, affecting refinancing options
- Down payment size - Larger down payments create lower LTV from day one, avoiding PMI and securing better rates
- Principal payments - Regular mortgage payments gradually reduce loan balance and lower LTV over time
- Second mortgages and HELOCs - Additional loans increase combined LTV (CLTV), which lenders also evaluate for risk
- Appraisal accuracy - Conservative appraisals may show higher LTV than expected, affecting loan terms and approval
Frequently Asked Questions
What is a good LTV ratio?
LTV ratios of 80% or below are considered good, allowing conventional loans without PMI. Ratios of 80-90% require mortgage insurance. Above 90% indicates higher risk with limited equity, often requiring FHA loans or higher interest rates from conventional lenders.
How do I calculate my LTV ratio?
Divide your loan amount by the property value, then multiply by 100. For example, a $240,000 loan on a $300,000 home equals 80% LTV ($240,000 / $300,000 × 100). Lower percentages indicate more equity and less risk.
What is the difference between LTV and CLTV?
LTV (Loan-to-Value) considers only the first mortgage. CLTV (Combined Loan-to-Value) includes all liens on the property like second mortgages and HELOCs. CLTV gives lenders a complete picture of total debt against the property.
How does LTV affect my mortgage rate?
Lower LTV ratios qualify for better interest rates because lenders face less risk. Borrowers with 20% down (80% LTV) get the best rates. Higher LTV ratios (above 80%) face higher rates and mandatory mortgage insurance premiums.
Can I remove PMI by lowering my LTV?
Yes, once your LTV drops to 80% or below through payments or appreciation, you can request PMI removal. For conventional loans, PMI automatically cancels at 78% LTV. FHA loans require refinancing to remove mortgage insurance premiums.
Does LTV matter for refinancing?
Yes, LTV is critical for refinancing. Most lenders require 80% LTV or lower for conventional refinancing without PMI. Cash-out refinancing typically requires even lower LTV (75-80%), while rate-and-term refinancing may allow up to 97% LTV with mortgage insurance.
