Your loan-to-value ratio (LTV) is one of the most important numbers in a mortgage transaction. It tells lenders how much risk they are taking on, and it directly affects whether you qualify, what interest rate you receive, and whether you have to pay private mortgage insurance. Here is everything you need to know about LTV and how to use it to your advantage.
To see how your LTV changes over the life of your loan, use our amortization calculator. If you are still early in the process, our mortgage payment calculator can help you estimate monthly costs at different down payment amounts.
LTV Definition
Loan-to-value ratio (LTV) is a financial metric that compares the size of your mortgage loan to the appraised value of the property you are buying or refinancing. Lenders use LTV to gauge risk: the higher the LTV, the more of the property’s value is financed with borrowed money, which means more risk for the lender.
LTV applies to purchase mortgages, refinances, home equity loans, and HELOCs. It is the single number that determines whether you need private mortgage insurance, what interest rate tier you fall into, and sometimes whether your application gets approved at all.
How to Calculate LTV
The formula is straightforward:
LTV = (Loan Amount / Appraised Home Value) x 100
Example: You want to buy a home appraised at $400,000 and you are taking out a mortgage for $320,000. Your LTV is $320,000 / $400,000 = 0.80, or 80%.
Notice that LTV uses the appraised value, not the purchase price. If you offer $410,000 for a home that appraises at $400,000, the lender uses $400,000 for the calculation. The difference between the purchase price and appraised value would need to come out of your pocket as additional cash at closing.
You can use our mortgage calculator to experiment with different loan amounts and see how they change your monthly payment alongside your LTV.
Why LTV Matters for Mortgage Approval
Lenders set maximum LTV thresholds for different loan programs. Exceed the threshold and your application is either declined or you must switch to a program with different requirements:
- Conventional loans — most allow up to 97% LTV for first-time buyers and 95% for repeat buyers, though rates and PMI costs rise as LTV increases.
- FHA loans — allow up to 96.5% LTV (3.5% down payment) with a credit score of 580 or higher.
- VA loans — allow up to 100% LTV (zero down payment) for eligible veterans.
- USDA loans — also allow 100% LTV for buyers in eligible rural and suburban areas.
- Jumbo loans — typically cap at 80% LTV, though some lenders extend to 90% with strong compensating factors.
The lower your LTV, the easier it is to qualify. An LTV of 80% or below is widely considered the gold standard because it eliminates PMI on conventional loans and gives you the widest range of lender options.
LTV and Private Mortgage Insurance (PMI)
Private mortgage insurance protects the lender if you default on a conventional loan with an LTV above 80%. PMI does not protect you — it protects the lender — but you pay the premiums.
PMI typically costs between 0.3% and 1.5% of the original loan amount per year, depending on your credit score and LTV. On a $320,000 loan, that is roughly $80 to $400 per month added to your payment.
You can request PMI removal once your LTV drops to 80% based on the original value of the home. Your servicer must automatically cancel PMI when your LTV reaches 78% based on the original amortization schedule. If your home has appreciated significantly, you may be able to get a new appraisal and request early cancellation.
Use our amortization calculator to find the exact month when your loan balance crosses the 80% mark.
How LTV Affects Your Interest Rate
Mortgage interest rates are not one-size-fits-all. Lenders use risk-based pricing, and LTV is one of the primary inputs. Here is how it typically works:
- LTV at or below 60% — you are in the lowest risk tier and will often receive the best available rate.
- LTV between 60% and 75% — rates are still competitive but may carry a small pricing adjustment.
- LTV between 75% and 80% — slight rate bump compared to lower LTV tiers, but you still avoid PMI.
- LTV between 80% and 95% — rates increase further, and PMI is now required on conventional loans.
- LTV above 95% — highest rates and highest PMI premiums. Limited program availability.
The difference between a 60% LTV rate and a 95% LTV rate can be 0.25% to 0.75% or more, which translates to thousands of dollars over the life of a 30-year mortgage.
Combined Loan-to-Value (CLTV)
If you have more than one loan secured by your property — for example, a first mortgage plus a home equity line of credit — lenders look at combined LTV (CLTV). The formula adds up all loan balances:
CLTV = (First Mortgage Balance + Second Mortgage/HELOC Balance) / Appraised Home Value x 100
Example: Your home is worth $500,000. You owe $300,000 on your first mortgage and have a $50,000 HELOC balance. Your CLTV is ($300,000 + $50,000) / $500,000 = 70%.
CLTV matters when you apply for a HELOC, a second mortgage, or a refinance. Most lenders cap CLTV at 80% to 90%. For more on how HELOCs work alongside your primary mortgage, read our guide on what is a HELOC.
How to Improve Your LTV
There are two ways to lower your LTV: reduce the loan amount or increase the property value.
Reduce the Loan Amount
- Make a larger down payment. Saving up for 20% down instead of 10% drops your starting LTV from 90% to 80%, eliminating PMI from day one.
- Make extra principal payments. Any additional amount you pay beyond your scheduled payment goes directly toward reducing your loan balance, which lowers your LTV month by month.
- Choose a shorter loan term. A 15-year mortgage builds equity faster than a 30-year mortgage because a larger share of each payment goes to principal.
Increase the Property Value
- Home improvements. Kitchen remodels, bathroom updates, and adding living space can increase your home’s appraised value. Focus on improvements with strong return on investment.
- Market appreciation. Over time, most real estate markets trend upward. If your home’s value has increased since you bought it, you can request a new appraisal to reflect the higher value and lower your effective LTV.
- Comparable sales. If nearby homes are selling at higher prices, that positive market activity may support a higher appraisal for your property.
LTV for Refinancing
When you refinance, LTV is recalculated using a new appraisal. If your home has gained value since you purchased it, your refinance LTV may be lower than your original purchase LTV, even if you have not paid down much principal.
For a cash-out refinance, your new loan amount includes the cash you are pulling out, which increases LTV. Most lenders cap cash-out refinance LTV at 80%, meaning you need at least 20% equity remaining after the new loan is funded.

Frequently Asked Questions
What is a good LTV ratio?
An LTV of 80% or lower is generally considered good because it eliminates the need for private mortgage insurance on conventional loans and qualifies you for better interest rates. An LTV of 60% or below puts you in the best pricing tier with most lenders. However, any LTV that fits within the guidelines of your chosen loan program can work — FHA loans, for example, are designed for borrowers at 96.5% LTV.
How do I calculate my LTV?
Divide your current mortgage balance by your home’s appraised value and multiply by 100. If you owe $240,000 on a home appraised at $300,000, your LTV is ($240,000 / $300,000) x 100 = 80%. You can check your current balance on your monthly mortgage statement and estimate your home’s value using recent comparable sales in your neighborhood.
What LTV do I need to avoid PMI?
You need an LTV of 80% or lower to avoid paying private mortgage insurance on a conventional loan. That means putting at least 20% down on a purchase or having at least 20% equity in your home for a refinance. Some lender-paid PMI options exist where the cost is built into a slightly higher interest rate, but the 80% LTV threshold is the standard cutoff for borrower-paid PMI.
Does LTV affect my interest rate?
Yes. Lenders use loan-level pricing adjustments (LLPAs) that increase your interest rate as LTV rises. A borrower at 95% LTV might pay 0.50% or more in rate compared to a borrower at 60% LTV, all other factors being equal. The impact varies by lender, credit score, and loan program, but lower LTV consistently results in better rate offers.
What is combined LTV?
Combined loan-to-value (CLTV) adds up the balances of all loans secured by your property — your first mortgage, any second mortgage, and any home equity line of credit — and divides by the appraised value. Lenders use CLTV when you apply for a second lien or HELOC to make sure the total debt against your home stays within acceptable limits, typically 80% to 90% of the home’s value.
