Loan-to-Value Calculator

LTV Calculator (Loan-to-Value Calculator)

Estimate LTV (loan-to-value), optional CLTV, and equity so you can model PMI exposure, compare mortgage quotes, and understand refinance thresholds.

Data as of Jan 2026

Calculate LTV and CLTV

Tip: For a purchase, use the contract price or appraised value (whichever your lender uses). For a refinance, use the most realistic current value estimate.

Results

LTV

90.0%

Above 80%: conventional PMI is often required.

CLTV

90.0%

Includes second liens / HELOC balances.

Equity

$45,000

10.0% equity

PMI Signal

Likely PMI on conventional financing

Rules vary by lender, loan type, and borrower profile.

How to use this result

  • Use LTV for PMI and pricing discussions on a single first mortgage.
  • Use CLTV when comparing piggyback loans or HELOC scenarios.
  • Pair this with the Mortgage Calculator to model the monthly impact.
  • See the PMI glossary guide for removal rules and caveats.

Why LTV matters for buyers and refinancers

Loan-to-value formula

LTV = loan amount ÷ property value. A $405,000 loan on a $450,000 home is 90% LTV. If you add a second lien, lenders may also look at CLTV (combined loan-to-value).

PMI and mortgage insurance pricing

Higher LTV usually increases risk-based pricing and can trigger private mortgage insurance (PMI) on conventional loans. Buyers often underestimate how much a higher LTV can change the total payment once PMI is added.

Down payment strategy and offer planning

If your LTV is close to a threshold, small changes in down payment or purchase price may materially change monthly costs. Pair this tool with the Down Payment Boss Fight and Closing Costs Calculator so you can plan both monthly payment and cash-to-close together.

Refinance and appraisal sensitivity

Refinance eligibility and pricing can change if an appraisal comes in lower than expected. Run a base case and a lower-value stress case to see how your LTV changes before you pay fees.

Use LTV with Payment and Cash Planning Tools

LTV alone is not enough. Pair it with payment, affordability, and closing-cost estimates.
