Mortgage leverage and equity planning

Loan-to-Value (LTV) Calculator

Compare mortgage debt with property value and see how optional second-lien or home equity line of credit amounts change the combined ratios.

Enter the property and secured-loan amounts

For current-home planning, use the property value and current principal balances you want to compare. For a new mortgage, use the loan and property values the lender is evaluating. Actual underwriting can use program-specific definitions.

Use the value appropriate for the comparison. A lender may use an appraisal, purchase price, or another value required by the loan program.
For current planning, use the current principal balance. For a transaction, use the first-mortgage amount being evaluated.
Optional. Include a home equity loan or other closed-end subordinate lien when relevant.
Optional. Use the amount currently outstanding on the home equity line of credit (HELOC).
Optional. Home equity combined loan-to-value (HCLTV) uses the full HELOC limit, not only the amount currently drawn.

Results will appear after valid values are entered.

First-mortgage LTV — First mortgage ÷ entered property value
Combined loan-to-value (CLTV) — First mortgage + second mortgage + drawn HELOC ÷ value
Home equity combined loan-to-value (HCLTV) — Uses the full HELOC credit limit when one is entered
Current secured debt entered — First + second mortgage + currently drawn HELOC
Estimated equity — Entered property value minus current secured debt
Estimated equity share — Estimated equity ÷ entered property value

80% LTV reference

Eighty percent is a useful mortgage reference point, especially when discussing private mortgage insurance (PMI) on many conventional loans. It is not a universal approval cutoff and this estimate does not determine PMI cancellation eligibility.

First-mortgage balance at 80% of entered value — 80% × entered property value
Position relative to 80% LTV — Based only on the first mortgage and entered value

What this estimate does not decide

The calculator does not determine mortgage approval, interest rate, mortgage-insurance requirements, appraisal acceptance, refinance eligibility, or PMI cancellation. Those decisions depend on the loan program, transaction, documentation, and lender or servicer rules.

For many mortgages, PMI cancellation rules use the home's original value rather than a new estimate of today's market value. Junior liens and other requirements can also matter.

Loan-to-value ratio (LTV) is simple division, but purchase values, second liens, home equity lines of credit (HELOCs), mortgage insurance, and lender rules can change how the number is used.

What Is Loan-to-Value Ratio (LTV) and Why Does It Matter?

Learn the formula, how LTV differs from combined loan-to-value (CLTV) and home equity combined loan-to-value (HCLTV), what 80% means, and why a lender may calculate the ratio differently.
