How LTV and CLTV are calculated
This tool compares entered lien balances with an assumed property value so you can see first-lien LTV and combined LTV side by side.
First-lien LTV divides the entered first mortgage balance by the assumed property value. Combined LTV adds the other entered lien balances before dividing by value. The property value is an assumption supplied by you; the calculator does not perform an appraisal or automated valuation.
First mortgage balance ÷ property value × 100Shows the first-lien leverage relative to assumed value.
(First mortgage + other liens) ÷ property value × 100Adds subordinate liens to show combined leverage.
Use a property value from a source appropriate for your planning purpose and label it as an assumption.
Enter the current first mortgage balance.
Add other liens such as a second mortgage or HELOC balance if you want CLTV.
Stress-test a lower property value to see how sensitive the ratios are.
Best used for
- Home-equity planning
- Cash-out refinance scenario checks
- Understanding leverage when multiple liens exist
What this tool does not answer
- The tool does not establish an accepted property value.
- It does not supply a maximum allowable LTV or CLTV.
- Credit limits, undrawn HELOC amounts and product rules may be treated differently by an actual provider.
How to read a sample result
Illustrative example: with a $500,000 assumed value, a $300,000 first mortgage produces 60% LTV. Adding $25,000 of other liens produces 65% CLTV.
The methodology below explains how this calculator treats the inputs and assumptions. Replace the sample values with your own planning figures. Results are estimates, not quotes, approvals, disclosures or recommendations.
Inputs and units
Property value, first-lien balance and other liens. All currency entries are U.S. dollars. Percentage fields take a number such as 6 for six percent, not 0.06. Repayment terms marked in months use whole months; horizons marked in years use whole years.
Calculation workspace
Enter your own figures in the calculator above. The starting values are examples only. No personal identifiers are needed to run a scenario.
How to interpret the result
Read every result together with the assumptions you entered. Changing an input changes the scenario, not product availability. Displayed amounts are rounded for readability.
Assumptions and limitations
An entered property value is not a lender valuation. An open credit line may need different treatment under a provider’s combined-leverage rules.
Review more than one scenario
Run a base case and then change one uncertain input at a time. Compare a shorter holding period, a higher cost or a different repayment term where those inputs are supported. Record which costs have not been entered. A precise-looking number can still rest on uncertain assumptions.
Invalid inputs and error recovery
If an input is missing or outside the calculator’s supported range, the page will ask you to correct it. Use negative values only in fields that explicitly allow them. A calculation error is not a credit decision.
Model documentation
The calculator methodology explains the inputs, assumptions and supported models. Use the result for planning and compare it with the provider’s written terms and applicable disclosures before making a decision.
