Understanding your LTV result
The bands below classify LTV against the 80% conventional PMI threshold and the higher LTV levels many conventional lenders still permit, though typically with mortgage insurance or additional conditions.
| LTV | Classification | Typical lending context |
|---|---|---|
| 80% or below | Low | At or below the common conventional PMI threshold |
| 80.01% – 95% | Standard | Above the PMI threshold; commonly requires mortgage insurance on conventional loans |
| Above 95% | High | Near or above typical maximum LTV limits for many conventional loan programs |
- LTV thresholds and PMI rules vary by lender, loan program and loan purpose (purchase, rate-and-term refinance, cash-out refinance); the bands above reflect common conventional-lending conventions, not a specific lender's terms.
- For a refinance or home equity loan, lenders often use combined loan-to-value (CLTV), which adds together the balances of all loans secured by the property — this calculator computes LTV for a single loan balance only.
- Property value is typically based on a professional appraisal for lending purposes, which may differ from an owner's estimate of market value.
What is loan-to-value (LTV) ratio?
Loan-to-value ratio is the outstanding loan balance divided by the property's appraised value or purchase price, expressed as a percentage. Fannie Mae and other conforming-loan guidelines use LTV as a core underwriting measure because it directly reflects how much equity cushion exists between the loan balance and the property's value — a lower LTV means more equity and generally less risk to the lender.
The 80% LTV level is a widely referenced threshold on conventional mortgages: at or below 80% LTV, private mortgage insurance (PMI) is typically not required, while above 80% LTV, PMI is commonly required to protect the lender against the smaller equity cushion. Different loan programs and lenders may apply different thresholds and rules.
LTV is also a key figure in refinancing and home equity lending, since lenders typically cap how much can be borrowed against a property based on a maximum LTV (or combined LTV, when multiple loans are secured by the same property) they are willing to extend.
How to use this LTV calculator
- Enter the current loan balance (or the proposed loan amount for a purchase or refinance).
- Enter the property's current market value or appraised value (or the purchase price for a new purchase).
- Read the LTV ratio, the resulting equity percentage, and the dollar amount of equity.
The formula behind loan-to-value ratio
LTV is calculated by dividing the loan balance by the property value and expressing the result as a percentage. Equity is the property value minus the loan balance, and equity percentage is simply 100% minus the LTV.
Worked example: a $320,000 loan balance on a property valued at $400,000 produces an LTV of 80% ($320,000 ÷ $400,000), equity of $80,000, and an equity percentage of 20%.
Common mistakes
- Using an owner's estimated market value instead of a lender's appraised value, which can produce an LTV different from what a lender will actually calculate.
- Confusing LTV with combined loan-to-value (CLTV) when more than one loan is secured by the same property, such as a first mortgage plus a HELOC.
- Assuming PMI automatically cancels the moment LTV crosses below 80% — most lenders require a formal request or a new appraisal to remove PMI, per servicer and investor rules.
- Overlooking that LTV changes over time as both the loan balance declines and the property value moves, so a snapshot LTV can become outdated within months in a fast-moving market.
- Applying a purchase-money LTV threshold to a cash-out refinance, where maximum allowable LTV is often lower due to the higher risk of cash-out transactions.
Preguntas frecuentes
What is a good loan-to-value ratio?
An LTV at or below 80% is commonly viewed favorably on conventional mortgages because it is the widely used threshold below which private mortgage insurance is typically not required. Lower LTV generally reflects a larger equity cushion and can be associated with more favorable loan terms, though specific requirements vary by lender and loan program.
How do I calculate loan-to-value ratio?
Divide the loan balance by the property's value (or purchase price) and multiply by 100. For example, a $320,000 loan on a $400,000 property gives an LTV of 80% ($320,000 ÷ $400,000 × 100). The remaining 20% represents the borrower's equity in the property.
What is the difference between LTV and CLTV?
LTV compares a single loan balance to the property value. Combined loan-to-value (CLTV) adds together the balances of all loans secured by the same property — for example, a first mortgage plus a home equity line of credit — and compares that total to the property value. Lenders often use CLTV, not just LTV, when underwriting a second loan or home equity product.
Does LTV affect my mortgage interest rate?
On many conventional loan programs, LTV can influence pricing — loans with higher LTV (less equity) are sometimes priced with a rate or fee adjustment because they represent more risk to the lender, while lower-LTV loans may qualify for more favorable pricing. Specific pricing structures vary by lender and loan program.
How can I lower my LTV?
LTV falls as the loan balance declines through regular payments or extra principal payments, or as the property's value rises through market appreciation or improvements. Because both figures can change independently, LTV should be recalculated periodically rather than treated as fixed at the time of loan origination.
