Above 80% LTV, a conventional loan normally requires PMI (private mortgage insurance) until you reach 20% equity. PMI protects the lender, not you — it typically drops off automatically at 78% LTV.

An estimate for planning — not financial advice. LTV is simply the loan divided by the property value; lender rules and thresholds vary.

Loan-to-value (LTV) is your mortgage as a percentage of the home's price, and in the US it decides PMI: with an LTV above 80% — less than 20% down — lenders require private mortgage insurance until you build 20% equity. This calculator shows your LTV and where you stand.

How this calculator works

LTV = loan ÷ price. A $475,000 loan on a $500,000 home is 95% LTV. The bigger your down payment, the lower the LTV.

Above 80% LTV, PMI is added to your monthly payment; it ends automatically at 78% LTV, or you can request cancellation at 80%. At 20%+ down there's no PMI at all.

LTV also affects your rate — lenders often price lower-LTV loans a little better — so a larger down payment can help twice.

A worked example

On a $500,000 home, your down payment sets the LTV and whether PMI applies:

5% down → loan
$475,000 · LTV 95% → PMI required
10% down → loan
$450,000 · LTV 90% → PMI required
20% down → loan
$400,000 · LTV 80% → no PMI

PMI ends automatically once your LTV reaches 78%, or you can ask to cancel it at 80%.

Who it's for

  • You want to know whether you'll pay PMI.
  • You're comparing 5%, 10%, and 20% down.
  • You want to understand equity thresholds.

Frequently asked questions

What LTV do I need to avoid PMI?

80% or below — meaning a 20% down payment or more. Above 80% LTV, private mortgage insurance is required until you build enough equity.

When does PMI go away?

It cancels automatically when your loan-to-value reaches 78% of the original value, and you can request cancellation once you hit 80%.

Does LTV affect my interest rate?

Often, yes — many lenders offer slightly better rates at lower LTVs, so a larger down payment can lower both your rate and your PMI.

How do I lower my LTV?

Put more down, buy a less expensive home, or build equity over time through payments and appreciation.
