Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Loan-to-value ratio | Equity percentage |
|---|---|---|
| $240k loan · $300k value | 80.00% | 20.00% |
| $180k loan · $200k value | 90.00% | 10.00% |
| $320k loan · $500k value | 64.00% | 36.00% |
| $95k loan · $250k value | 38.00% | 62.00% |
How This Calculator Works
Enter the loan amount and the property value. The calculator divides one by the other to give the loan-to-value ratio as a percentage, and shows the complement — the equity share, the portion of the value you own outright.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
A $240,000 loan against a $300,000 property is an 80% loan-to-value ratio. The remaining 20% is equity — and 80% is the level at which many lenders stop requiring private mortgage insurance.
Key Insight
Loan-to-value drives both approval and cost. Crossing below 80% typically removes private mortgage insurance and unlocks better refinance terms, so a modest extra principal payment can pay for itself.
PMI economics — when LTV crosses 80%
On conventional loans, Private Mortgage Insurance (PMI) is required when LTV exceeds 80%. PMI protects the LENDER, not the borrower, against default losses. PMI typically costs 0.3-1.5% of the loan amount annually, paid monthly as part of the mortgage payment. For a $400K loan at 0.7% PMI: $2,800/year = $233/month.
PMI ends automatically when LTV drops below 78% based on the original property value (per Homeowners Protection Act of 1998). Borrowers can request PMI removal at 80% LTV based on current appraised value — useful in appreciating markets. For a property purchased at $500K with $25K down (95% LTV), PMI continues until $110K of principal is paid OR an appraisal at $625K+ supports 80% LTV based on current value.
FHA loans have different mortgage insurance: MIP (Mortgage Insurance Premium) lasts the LIFE of the loan for loans with <10% down, regardless of LTV reduction. This is why many borrowers refinance from FHA to conventional once they reach 80% LTV — to escape lifetime MIP. The structural advantage of conventional with PMI (cancellable) vs FHA with lifetime MIP makes conventional preferred when borrower can qualify.
Combined LTV — when seconds add to firsts
Combined Loan-to-Value (CLTV) includes all mortgages secured by the property — first mortgage + second mortgage + HELOC outstanding balance. CLTV is what lenders use when assessing risk of additional debt. Most home equity lenders set CLTV maximums of 80-95%, depending on credit score, property type, and loan purpose.
Example: $500K property, $300K first mortgage (60% LTV), $50K HELOC outstanding (combined 70% CLTV). The borrower applying for a $100K additional HELOC would be at 90% CLTV — at the upper edge of typical lender approval. Most lenders' max CLTV for cash-out HELOCs is 85-90%; some specialty lenders go to 95%.
For homeowners managing total leverage: CLTV combined with debt-service ratios determines borrowing capacity. As home values appreciated 2020-2022, CLTV ratios dropped on existing debt, creating capacity for tax-deductible HELOC borrowing (under TCJA 2017, HELOC interest deductibility is limited to debt used for home improvement). As home values stabilized or fell 2023-2024 in some markets, CLTV recovery slowed.
U.S. mortgage LTV limits by loan type (2024-2025)
Reference maximum LTV ratios and key features for major U.S. mortgage programs.
| Loan type | Max LTV | PMI / MI requirement | Notes |
|---|---|---|---|
| Conventional 30-year (Fannie/Freddie) | 97% (3% down) | PMI required until 78% LTV | Most common |
| FHA 30-year | 96.5% (3.5% down) | MIP for life of loan (<10% down) | Easier qualification |
| VA (veterans) | 100% (no down) | Funding fee 1.4-3.6% | Veterans only |
| USDA (rural) | 100% (no down) | Guarantee fee 1% upfront + 0.35% annually | Rural areas only |
| Jumbo (>conforming limit) | Typically 80-90% | PMI required >80% | Higher rate; stricter underwriting |
| Investment property | 80-85% max | Yes if >80% | Higher rate; reserves required |
| Cash-out refinance (conventional) | 80% | Yes if >80% | |
| HELOC / second mortgage | 85-95% CLTV | n/a | Combined with first mortgage |
Maximum LTV is the upper bound; actual approval depends on credit score, DTI, employment history, and reserves. Best rates are typically available at 80% LTV or lower. Borrowers above 80% should compare conventional (with cancellable PMI) vs FHA (with lifetime MIP) — over a 7-10 year holding period, conventional usually wins.
Frequently Asked Questions
What is loan-to-value ratio?
It is the loan amount as a percentage of the property's value. A lower ratio means more equity and less risk for the lender.
Why does loan-to-value matter?
Lenders use it to decide approval, interest rate, and whether mortgage insurance is required. A lower ratio generally earns better terms.
What is the 80% threshold?
At or below 80% loan-to-value, many lenders no longer require private mortgage insurance, because the equity cushion is considered sufficient.
How do I lower my loan-to-value ratio?
Pay down the loan balance, or benefit from a rise in the property's value. Both increase equity and reduce the ratio.
What property value should I use?
Use the appraised value for a new loan, or a current market estimate for an existing one. The cited home price benchmark gives a rough national reference.
When is this calculator unreliable?
When 'value' is uncertain — appraisal, purchase price, and online valuation estimates (Zillow, Redfin) can differ by 10-20%, leading to different LTV calculations. Also unreliable for combined LTV calculations (don't forget to add second mortgages and HELOC balances), or in rapidly changing markets where the value used in the calculation may not reflect current market value. For lending decisions, the lender's appraised value is what matters.

Methodology & Review
Loan-to-Value (LTV) ratio equals loan amount / property value × 100. The calculator returns LTV as a percentage. LTV is the primary risk metric in U.S. mortgage lending — higher LTV means smaller borrower equity cushion and higher lender risk. Conventional loans typically max at 80% LTV (or up to 97% with PMI); FHA up to 96.5%; VA up to 100%; USDA up to 100%. PMI (Private Mortgage Insurance) is typically required when LTV exceeds 80% on conventional loans, costing 0.3-1.5% of loan amount annually until LTV drops below 78%. RELIABILITY: Reliable for direct LTV calculation using documented property value. Less reliable when 'value' is uncertain (appraisal vs purchase price vs Zillow estimate can differ 10-20%), during rapid price changes (LTV calculated against a recent peak may understate true current LTV after a correction), or for combined LTV calculations involving second mortgages and HELOCs that need to be added together.
