Understanding Loan-to-Value (LTV)
How we calculate. LTV % = (loan ÷ value) × 100. See our methodology and accuracy policy .
Real-world scenario: A typical Loan-to-Value (LTV) case uses loan amount 320000 and property value 400000. Enter the same figures below to reproduce the worked path.
What is Loan-to-Value (LTV)?
A lending risk metric. Higher LTV means less equity cushion—often tied to mortgage insurance thresholds.
- Use appraisal or purchase price per lender rules
- Combined LTV includes second liens
- Equity % ≈ 100 − LTV when definitions match
The Formula
Worked Example
Common Use Cases
- Mortgage quotes: PMI thresholds
- Refinance checks: equity position
- HELOC planning: available equity
Pro Tips
- Falling values raise LTV
- Extra principal cuts LTV
- Ask which value the lender uses
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |

Limitations: Loan-to-Value (LTV) results are educational finance aids—not loan offers, investment advice, or tax counsel. Confirm figures with a qualified professional and your contract.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
