Key takeaways:

LTV and CLTV measure how much of your home’s value is financed with loans.
LTV looks only at your primary mortgage—CLTV counts all loans tied to your home.
Borrowing is generally easier when you have lower ratios.

You'll come across a lot of jargon in the finance world. It's smart to familiarize yourself with important terms so you can make informed choices. If you’re applying for a mortgage, HELOC, or home equity loan, you may hear lenders talk about numbers like LTV and CLTV.

The terms sound technical, but CLTV and LTV are simply ratios lenders use to measure how much of your home’s value is tied up in loans. LTV, which means loan-to-value, looks at your primary mortgage balance compared to your home’s value. CLTV, or combined loan-to-value, looks at all loans secured by your home, including home equity loans and HELOCs.

These ratios could come into play if you decide to borrow against your home equity. One of them tends to be much more important in getting approved for HELOCs and home equity loans.

What is LTV?

Loan-to-value (LTV) is your primary mortgage balance compared to your home’s appraised or market value.

Here’s how to calculate LTV:

LTV = mortgage balance / home value

For example, say your home is worth $300,000, and your mortgage balance is $180,000. To calculate LTV, divide your mortgage balance by the home value. Then, multiply the answer by 100 to show it as a percentage. Here’s the calculation:

Step 1: $180,000 / $300,000 = 0.60

Step 2: 0.60 x 100 = 60%

What is CLTV?

Combined loan-to-value (CLTV) is the combined value of all loans secured by your home compared to your home’s appraised or market value. It includes your primary mortgage plus any other loans against your home, such as HELOCs or home equity loans. CLTV is used instead of LTV if you have loans in addition to your primary mortgage.

Here’s how to calculate CLTV:

CLTV = total mortgage loan balances / home value

Let's assume the same numbers from above, with the addition of a $45,000 home equity loan. The CLTV calculation would then be:

Step 1: $180,000 + $45,000 = $225,000

Step 2: $225,000 / $300,000 = 0.75

Step 3: 0.75 x 100 = 75%

Is CLTV the same as customer lifetime value?

What does 80% CLTV mean?

A CLTV of 80% means that the total debt on a home, including the primary mortgage as well as any HELOCs or home equity loans, equals 80% of the home’s current value. Home equity lenders often have a limit of 80% CLTV.

CLTV vs. LTV: What’s the difference?

Feature	LTV	CLTV
What it measures	Ratio of primary mortgage balance to home value	Ratio of all loans secured by the home to its value
Loans included	Primary mortgage	All home loans, including primary mortgage, home equity loans, and HELOCs
Why lenders use it	To set your mortgage rate and decide if you need private mortgage insurance (PMI)	To evaluate home equity and set total home loan limits
When it matters most	When first purchasing a home or refinancing	When applying for a home equity loan or HELOC

Is CLTV higher than LTV?

Your CLTV will be higher than your LTV if you have any home loans other than the primary mortgage, such as a HELOC or home equity loan. One of the mechanics of HELOCs and home equity loans is that they raise CLTV, but not LTV. If you only have one loan on your home, your CLTV and LTV will be the same number.

Why CLTV matters more for home equity loans

When you apply for a home equity loan, CLTV is nearly always more important than LTV. That's because CLTV considers all the debt on your home, making it a more accurate way for lenders to evaluate your home equity.

For example, if you have a $400,000 home with $200,000 left on the mortgage, your LTV is 50%. That looks like plenty of equity to borrow against.

But you could already have other loans against your home. If you have a $160,000 home equity loan, then the total debt on your home including your mortgage is $360,000—a 90% CLTV. Most lenders won’t approve you for another home equity loan with that much debt tied to the house already.

Home equity lenders are also normally the last in line if a borrower defaults. After a foreclosure, the lender on the home’s primary mortgage gets paid first. Home equity lenders use CLTV to make sure there’s still an equity cushion, meaning the home is worth more than all the loans on it.

What is considered a good LTV?

If you’re interested in using your home equity to get a loan, you’re probably going to need an LTV well below 80%. Many lenders have an 80% to 85% CLTV limit, which includes all loans on the home. In other words, they want you to still have at least 15% to 20% equity including the home equity loan.

A good LTV in this situation is one low enough to get the home equity loan you want. That may be an LTV of 50%, 60%, 70%—or a different number entirely, depending on your home’s value and how much you want to borrow. Any other loans you have against your home also matter, since lending decisions are ultimately based on your CLTV.

LTV numbers aren’t really considered good or bad, though. Your LTV is probably going to be high when you first buy a home with a mortgage. As you make your home payments, LTV gradually decreases all the way down to 0% when your mortgage is paid off.

Tips to lower CLTV before applying

If you want to lower your CLTV before applying for a loan, here are steps you can take:

Reduce mortgage debt. Pay down your mortgage or other loans secured by your home.
Increase your home’s value. Make home improvements or renovations that boost your property's market value.
Change your borrowing plan. Borrow less money.
Give it time. Wait for your equity and home value to build.

Home Equity Loans

FAQs: What is the difference between CLTV and LTV in home equity loans?

An 80% CLTV means the total of all loans secured by your home equals 80% of the home's appraised value. On a home appraised at $400,000, for example, that's $320,000 in total mortgage balances ($400,000 x 0.80 = $320,000).

A high CLTV may limit your home equity loan and HELOC options or affect your rate. If that’s the case, you may want to pay down your mortgage balance if possible, borrow a smaller amount, or see if you qualify with another lender, as requirements vary.

CLTV is higher than LTV when you have more than one loan secured by your home. If you only have a primary mortgage, the two ratios are the same number. A home equity loan or HELOC raises only your CLTV, because LTV reflects only the primary mortgage balance. The gap between the two ratios grows as you take on more home-secured debt.

To calculate CLTV, add the balances of all your home loans, including your primary mortgage as well as any second mortgages such as home equity loans or HELOCs. Divide that total by your home's current appraised value, then multiply by 100. For example, a $250,000 mortgage balance plus a $50,000 home equity loan, divided by a $400,000 appraised value, equals a CLTV of 75%.
