Combined LTV (CLTV) Calculator
This CLTV calculator adds every lien against the home. It shows combined loan-to-value and how much equity is still reachable.

Most lenders count a HELOC at its full credit limit rather than its drawn balance, so enter the limit if you want the number underwriting will use. Estimate only.
Combined loan-to-value adds every lien recorded against the property — first mortgage, second mortgage, HELOC — and divides by value. It is the ratio that governs whether you can take out additional equity.
A comfortable first-mortgage LTV can still sit behind a high CLTV. Lenders considering a second lien look at the combined figure, not just the first.
These figures are estimates. For neutral, official guidance on mortgage costs and what lenders can charge, see the CFPB's Owning a Home guide.
How to Use This Calculator
- 1
Enter the property value.
- 2
Enter the first mortgage balance, then any second mortgage.
- 3
Enter the HELOC — use the credit limit rather than the drawn balance, because most lenders underwrite to the limit.
- 4
Set the target CLTV your program allows and read the remaining borrowing room.
The Formula & Assumptions
Liens = first + second
+ HELOC limit
CLTV = liens ÷ value
× 100
Room = (value × target%)
− liens
A HELOC counts at its full line, not its balance, on most programs. An undrawn $100,000 line still consumes $100,000 of combined loan-to-value, which surprises borrowers who opened a line and never used it.
Typical CLTV ceilings run to about 85% for a home equity loan or HELOC on a primary residence, with some lenders going to 90% for strong credit. Second homes and investment properties are capped lower.
If the number comes back over your target, the levers are a higher appraised value, paying down the second or closing an unused HELOC line before applying.
Frequently Asked Questions
What CLTV can I go to on a Florida HELOC?
Commonly up to 85% on a primary residence, and some lenders reach 90% for strong credit and reserves. Second homes and rentals are typically capped well below that. The ceiling varies by lender, so it is worth shopping.
Does an unused HELOC hurt my CLTV?
Usually yes. Most lenders count the full credit line rather than the drawn balance, so an open, unused line reduces what you can borrow elsewhere. Closing a line you do not need can restore that room.
What is the difference between LTV and CLTV?
LTV counts only the first mortgage. CLTV counts every lien against the property. When you apply for a second mortgage or HELOC, the combined figure is the one that decides how much you can take.
How does a special assessment affect this?
It does not change CLTV directly, but a Florida condo facing a large assessment can see its market value marked down, which raises CLTV on the same balances and can close the window on additional borrowing.

It calculates combined loan-to-value: every lien on the property added together and divided by its value. Lenders use it whenever a second mortgage or HELOC sits behind the first.
CLTV Calculator in Florida
Florida condo owners meet the CLTV cap sooner than house owners, because a pending special assessment can hold a building's values flat while the first mortgage barely moves. Homestead protection does not change the arithmetic here. Lenders still size the second lien on value and total debt.
How the CLTV Calculator Works
The calculator adds your first mortgage to any second lien and divides the total by the property value. For a line of credit it uses the full approved limit, not the drawn balance.
The CLTV Formula, Explained
CLTV = (first mortgage + second mortgage) / property value
A HELOC counts at its full limit even when you have drawn none of it. Lenders assume you could draw it tomorrow, which is why an unused line still limits what else you can borrow.
Most home-equity programs cap CLTV between 80% and 90%. That cap, rather than your income, is usually what decides the size of a second mortgage.
The Complete CLTV Calculator Guide
CLTV exists because the second lender is behind the first in a foreclosure. Everything owed ahead of them is risk they cannot control, so they measure the whole stack rather than their own slice.
That is why opening a HELOC you do not use still costs you flexibility. The limit occupies room under the cap, and a later cash-out refinance has to work around it.
Run CLTV before applying for a second mortgage. If the number lands above the lender's cap, more income will not fix it, but a higher appraisal or a smaller request might.
CLTV Calculator FAQ
Does an unused HELOC count toward CLTV?
Yes, at its full approved limit in most programs. Closing an unused line is sometimes the fastest way to bring CLTV back under a cap.
What CLTV will lenders allow?
Commonly 80% to 90% for home-equity loans and lines, with the higher end reserved for stronger credit. Investment properties are usually held to a lower cap than primary homes.
