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.
