About Combined Loan-to-Value (CLTV) Calculator

The Combined Loan-to-Value (CLTV) Calculator measures total debt secured against a property across multiple liens (first mortgage + second mortgage + HELOC) relative to property market value.

Formula & Mathematical Calculation

CLTV (%) = ( [ 1st Mortgage Balance + 2nd Mortgage / HELOC Drawn ] / Property Value ) × 100

HCLTV (%) = ( [ 1st Mortgage Balance + Total HELOC Credit Limit ] / Property Value ) × 100

Calculation Example

Example: Home Value: $500,000 | 1st Mortgage: $300,000 | HELOC Drawn: $50,000 (Total Limit: $100,000) → CLTV = 70.0% | HCLTV = 80.0%.

Frequently Asked Questions

CLTV equals the sum of all loan balances secured by the property divided by the appraised property value: CLTV (%) = [(First Mortgage + Second Mortgage + Home Equity Liens) ÷ Property Value] × 100.

CLTV measures only currently drawn loan balances. High CLTV (HCLTV or Total LTV) includes the total credit limit of any open HELOCs, regardless of whether the line of credit is currently drawn or empty.

Most lenders cap CLTV between 80% and 85% for second-lien approvals, requiring at least 15% to 20% unencumbered equity remaining across all loans to protect against property depreciation.

Second mortgages occupy a subordinate lien position behind your primary mortgage. Because lenders face total loss risk if a property is foreclosed, loans with CLTV above 80% carry higher interest rates and stricter credit requirements.
