What is the difference between LTV and CLTV?

LTV (Loan-to-Value) considers only the first mortgage. CLTV (Combined Loan-to-Value) adds ALL mortgages, HELOCs, and liens. If your home is worth $400K with a $280K first mortgage and $40K HELOC: LTV = 70%, CLTV = 80%. Lenders use whichever is relevant to the decision — LTV for PMI, CLTV for additional lending.

What CLTV do I need for a HELOC?

Most lenders require CLTV ≤ 80-90% for a HELOC. Some banks go up to 90% for prime borrowers (720+ credit, low DTI). Credit unions sometimes allow 95-100% CLTV for their members. The lower your CLTV, the better rate you'll receive.

Does CLTV affect PMI?

PMI is primarily based on LTV (first mortgage only). You can remove PMI when LTV drops to 80%. However, if you have a second mortgage or HELOC, some lenders may consider CLTV when refinancing to remove PMI.

How do I lower my CLTV?

Three ways: (1) Pay down mortgage principal faster, (2) Make extra payments on HELOCs/second mortgages, (3) Increase property value through strategic improvements. Home appreciation also helps — if your property value rises, CLTV drops automatically.

What CLTV is needed for a cash-out refinance?

Conventional: 80% max CLTV. FHA: 80% (streamline has no CLTV cap). VA: 90-100% depending on lender. These are the new CLTV after the refi — the cash-out amount plus remaining balance must stay below the threshold.

Can CLTV exceed 100%?

Yes — this means you are "underwater" (you owe more than the property is worth). This can happen if property values decline. CLTV above 100% makes it very difficult to sell (you'd owe money at closing) or refinance. VA and some HARP-successor programs may still help at high CLTVs.

About the CLTV Calculator

The Combined Loan-to-Value (CLTV) ratio measures your total mortgage debt against your property's value, combining all liens — first mortgage, second mortgage, HELOCs, and any other secured loans. While LTV looks at just the first mortgage, CLTV gives lenders the complete picture of how leveraged your property is.

CLTV matters most when you're trying to take on additional debt. Want a HELOC? Most lenders cap CLTV at 85-90%. Refinancing? Conventional cash-out refi typically requires CLTV ≤ 80-85%. Even PMI removal considers your total debt load, not just the first mortgage. A homeowner with a 75% LTV who takes a HELOC might find their CLTV at 90%, limiting future borrowing options.

This calculator computes both LTV and CLTV, maps your position against common lending thresholds, and shows how property value changes would affect your eligibility. The equity composition bar visualizes exactly how your home's value is split between different debts and your ownership stake.

When This Page Helps

Use this when a property already has more than one lien or when you're planning to borrow against existing equity. It clarifies how close you are to lender limits and how much room remains for refinancing or a HELOC.

How to Use the Inputs

Enter your first mortgage balance (principal remaining)
Add any second mortgage, HELOC, or other lien balances
Enter the current estimated property value (use recent comps or Zillow Zestimate)
Enter the original purchase price to see appreciation
Review LTV vs CLTV and lending eligibility thresholds
Check the value scenarios table to see how changes affect your ratios

Formula used

LTV = First Mortgage Balance ÷ Property Value × 100
CLTV = (First Mortgage + Second Mortgage + HELOC + Other Liens) ÷ Property Value × 100
Equity = Property Value − Total Debt
Equity % = Equity ÷ Property Value × 100
Max Additional Borrowing = Property Value × Max CLTV% − Total Current Debt

Example Calculation

Result: LTV 66.7% — CLTV 77.8% — Equity $100,000 (22.2%)

LTV = $300,000 ÷ $450,000 = 66.7%. CLTV = ($300,000 + $50,000) ÷ $450,000 = 77.8%. Equity = $450,000 − $350,000 = $100,000 (22.2%). Eligible for most refinance products. Additional HELOC capacity at 90% CLTV = ($450,000 × 0.90) − $350,000 = $55,000.

Tips & Best Practices

CLTV matters most when applying for HELOCs, second mortgages, or cash-out refinances
Keep CLTV below 80% for maximum borrowing flexibility and best rates
Pay down the highest-RATE loan first (usually HELOC), not the highest-balance loan
Get a professional appraisal if you believe your home has appreciated significantly — it could unlock borrowing capacity
A HELOC with zero balance still counts toward CLTV if the credit line is open at some lenders

Borrowing Thresholds

Lenders usually care about the total debt stack, so CLTV is the key number when a second mortgage or HELOC is involved.

Equity Position

A rising property value lowers CLTV even if the balance stays flat, which can improve refinance options over time.

Planning Use

Test both current value and conservative value scenarios before assuming a new loan will be approved.

Sources & Methodology

Methodology

This worksheet calculates first-lien LTV from the first mortgage balance and property value, then adds the entered second mortgage, HELOC, and other liens to compute combined loan-to-value ratio. It also derives current equity and the additional borrowing room implied by a user-selected maximum CLTV threshold.

The result is a planning estimate rather than a credit decision. Different lenders count HELOC limits, unpaid balances, and cash-out rules differently, so the page should be used to understand how stacked liens affect leverage, not as a guarantee of refinance or HELOC approval.
