Calculate Your LTV & CLTV Ratio
Use our free LTV calculator to instantly compute your loan-to-value ratio and combined loan-to-value (CLTV) for your mortgage. Understanding your LTV and CLTV ratios is essential when securing a conventional loan—these metrics show lenders how much equity you have in your property and directly determine if you'll need private mortgage insurance (PMI), what interest rate you'll receive, and whether you qualify for specific loan programs. This free tool calculates your exact ratios based on property value and all outstanding loans, helping you optimize your borrowing power before you apply.

Understanding LTV and CLTV Ratios: Complete Guide for Homebuyers
When you apply for a conventional mortgage loan—whether for purchase, cash-out refinance, or home equity access—two critical numbers determine your approval odds, interest rate, and monthly costs: Loan-to-Value (LTV) and Combined Loan-to-Value (CLTV). Lenders use these ratios to measure lending risk, price your loan, and decide whether you'll pay private mortgage insurance (PMI). Understanding your LTV and CLTV ratios before you apply can save you thousands in unnecessary interest and insurance costs. Use our calculator above to instantly see how your down payment and existing loans affect your borrowing power and mortgage terms.
What Is LTV (Loan-to-Value) Ratio?
LTV (Loan-to-Value) is the ratio of your primary mortgage balance or loan request to the appraised value or purchase price of the property. The basic formula is: LTV = (Loan Amount ÷ Property Value) × 100. For example, if you're buying a $400,000 home with a $320,000 mortgage, your LTV is 80%.
Why does your LTV ratio matter so much? A lower LTV ratio indicates you have greater equity and less risk for the lender. If your LTV is 80% or below, you typically avoid PMI on conventional loans, which can save $200–$500+ monthly depending on your loan amount. LTV also governs your maximum borrowing capacity: conventional cash-out refinances typically max out at 80% LTV, while purchase loans can reach 95–97% for qualified borrowers through low-down-payment programs. Explore our guide on low-down-payment conventional programs to see all your options if you're buying with minimal savings.
What Is CLTV (Combined Loan-to-Value) Ratio?
CLTV (Combined Loan-to-Value) expands the LTV calculation to include all outstanding loans secured by your home—not just your first mortgage. This includes second mortgages, home equity lines of credit (HELOCs), construction loans, and any other recorded liens against the property. The formula is: CLTV = (Total of All Loans ÷ Property Value) × 100.
Here's a practical example: Suppose your first mortgage balance is $280,000 and you carry a $50,000 HELOC against the same $400,000 property. Total debt = $330,000, so your CLTV = 82.5%. Even though your primary LTV is only 70%, the higher CLTV could limit your refinancing options, higher rates, or stricter underwriting because lenders see total leverage as a greater default risk. CLTV becomes critical when refinancing a first mortgage while keeping subordinate liens in place, or when applying for new home equity products. For detailed guidance, see our article on cash-out refinance options and limits.
How Lenders Use LTV and CLTV in Underwriting
Risk Pricing & Interest Rates
Lenders charge higher interest rates to borrowers with LTV ratios above 80% because higher leverage = higher default risk. For every 5-10% increase in LTV above 80%, expect your rate to increase by 0.25% to 0.75%. Additionally, borrowers with LTV exceeding 80% must carry private mortgage insurance (PMI) until equity reaches 20%. See our detailed guide on when PMI goes away to understand your path to cancellation.
Loan Program Limits
Maximum LTV varies by loan type. For conventional purchase loans on primary residences, LTV can reach 95–97% through low-down-payment products. Investment properties typically cap at 75–85% LTV. CLTV limits also apply strictly for HELOCs or subordinate financing—most lenders cap CLTV at 85% even if primary LTV qualifies for higher leverage.
PMI Triggers & Costs
When your LTV exceeds 80%, private mortgage insurance is mandatory on conventional loans to protect the lender's interest. Once your LTV drops to 78–80% through principal payments, home appreciation, or a combination of both, you have the right to request PMI cancellation under federal law. The faster you reach that 80% threshold, the sooner you eliminate this cost. Check our comprehensive guide on when PMI is required to strategize your paydown approach.
Cash-Out Refinance Restrictions
Most conventional cash-out refinances require LTV ≤ 80%. CLTV also matters if you're keeping an existing second mortgage or HELOC in place—total leverage must stay within lender guidelines. If your CLTV is too high, you may need to pay down subordinate loans first or explore rate-and-term refinance options instead of cash-out scenarios.
Equity vs. LTV: Understanding Your Home's Financial Position
Your home equity is directly inverse to your LTV: Equity % = 100% − LTV%. If you have a 75% LTV, you own 25% equity. This equity represents the difference between your home's market value and all outstanding loans against it. High equity provides financial flexibility—you can sell without a loss, tap equity for renovations or debt consolidation, or refinance on favorable terms. When CLTV is high (above 90%), you have minimal financial cushion, making lenders cautious about new lending, especially in falling or uncertain markets. Our calculator instantly shows your exact equity position so you can make informed financial decisions before approaching lenders.
Real-World LTV and CLTV Scenarios
Scenario A – Purchase with 10% Down
You find a $350,000 home, make a 10% down payment ($35,000), and borrow $315,000. Your LTV = 90%. You'll be required to pay PMI because you're above the 80% threshold. Using our CLTV calculator, if you have no second loan, CLTV equals LTV at 90%. PMI will reduce after each payment, but expect 5–7 years before reaching 80% LTV naturally.
Scenario B – Refinance with Existing HELOC
Your first mortgage is $200,000 on a $500,000 home (40% LTV). However, you also carry an $80,000 HELOC from years past. Total debt = $280,000 → CLTV = 56%. Excellent news: strong equity and low CLTV mean competitive refinance rates, easy approval, and potential for favorable cash-out refinance terms or additional home equity access. You're in a strong negotiating position.
Scenario C – High Leverage (Caution)
Property value $300,000, first mortgage $270,000, second mortgage $25,000 → CLTV = 98.3%. This high ratio presents a challenge. Most conventional lenders would decline further lending unless you pay down balances substantially. PMI on the first mortgage would be expensive, and refinancing options are severely limited. Our calculator flags "High Risk" to alert you to take action—pay down debt, wait for appreciation, or explore non-conventional loan programs.
Scenario D – Strategic Refinance Opportunity
First mortgage $180,000 on a $350,000 home (51% LTV), no second mortgage. Interest rate is 5.5%. CLTV = 51% (low risk). This borrower is an excellent candidate for rate-and-term refinancing to lower rates, or potentially a cash-out refinance up to 80% LTV ($280,000) without PMI. Use our cash-out refinance calculator to explore how much you could borrow.
Strategies to Improve Your LTV and CLTV Ratios
Increase Your Down Payment (Purchases)
Every dollar of down payment reduces your LTV dollar-for-dollar. A 20% down payment eliminates PMI entirely. If you're currently saving, prioritize reaching 20% down to unlock the best conventional rates and avoid mortgage insurance altogether.
Accelerate Mortgage Principal Paydown
Pay extra toward your mortgage principal each month to reduce LTV faster. Even an extra $100–$200 monthly compounds over time. Our extra payment calculator shows exactly how much interest you'll save by paying ahead of schedule.
Leverage Property Appreciation
When your home's market value increases (due to market conditions or home improvements), your LTV and CLTV both drop automatically without any loan reduction. A $25,000 appreciation on a $300,000 home reduces LTV by 8.3% instantly. If you're close to the 80% PMI threshold, strategic home renovations could push you over the top.
Pay Off Subordinate Loans First
If CLTV is holding you back from refinancing, consider paying off your second mortgage or HELOC before refinancing the first. This reduces total leverage and improves your CLTV dramatically, unlocking better rates and terms on the primary mortgage.
Explore Refinance Options Strategically
As your LTV improves, refinancing becomes more attractive. When you cross the 80% LTV threshold, PMI-free products open up. Use our rate-and-term refinance tool to compare scenarios and lock in savings before rates move.
Monitor Your LTV and CLTV Progress Over Time
Your LTV and CLTV aren't static—they improve over time as you make payments and your home appreciates. Use this calculator quarterly or semi-annually to track progress, especially when you're approaching the critical 80% LTV threshold where PMI cancellation becomes possible. Knowing your exact position empowers you to negotiate better terms, avoid unnecessary insurance costs, and time your refinance strategically for maximum savings.
