Loan-to-Value (LTV) Calculator
Check your LTV ratio, your home equity, and exactly how much more principal or appreciation gets you to the 80% mark where PMI goes away.
The LTV formula
Balance $240,000 · home value $320,000
LTV = 240,000 ÷ 320,000 = 75% → equity of $80,000 (25%). Already under 80%, so PMI shouldn't apply.
Why LTV matters
| LTV | What it means |
|---|---|
| ≤ 80% | No PMI; best rates; refinance and HELOC eligible |
| 80–90% | PMI on conventional loans; decent options |
| 90–97% | Higher rates and PMI; fewer programs |
| > 100% | "Underwater" — you owe more than the home is worth |
Lenders read LTV as risk: the more equity you hold, the more cushion they have if you default. Getting under 80% unlocks PMI removal (request at 80%, automatic at 78% under the Homeowners Protection Act), better refinance pricing, and home equity borrowing. You can get there faster with extra principal payments — or via a new appraisal if your market has appreciated.
Frequently asked questions
What is a good loan-to-value ratio?
80% or below — it avoids PMI and gets the best rate tiers. Above 95–97%, options narrow considerably.
How do I calculate my LTV?
Loan balance ÷ current home value × 100. $240,000 on a $320,000 home = 75%.
At what LTV can I remove PMI?
Request cancellation at 80% LTV; lenders must auto-terminate at 78% on conventional loans.
