Simple definition
Loan-to-value ratio, or LTV, compares how much you're borrowing to what the home is worth. Think of it as measuring how much of the house the bank owns versus you. A $180,000 loan on a $200,000 home is 90% LTV. The lower your LTV, the less risk to the lender and the better terms you tend to get.
Why it matters
LTV drives some of the biggest costs of buying a home. It determines whether you'll pay private mortgage insurance, the interest rate you're offered, and whether you qualify at all, so lowering it can save real money over the life of the loan.
Real-life example
You buy a $200,000 home with a $40,000 down payment, borrowing $160,000. Your LTV is $160,000 ÷ $200,000 = 80%. Hitting 80% or below often lets you avoid private mortgage insurance, whereas a smaller down payment and higher LTV would typically require it.
Formula
Loan-to-Value Ratio = Loan Amount ÷ Appraised Home Value
Common mistakes
- Making a small down payment, then paying private mortgage insurance for years.
- Forgetting that a low appraisal raises your LTV and can change your loan terms.
- Assuming home price, not the appraised value, is what lenders use.
- Not tracking your LTV as you pay down the loan and could drop mortgage insurance.
Pro tips
- Aim for 80% LTV or lower to avoid private mortgage insurance where possible.
- Request cancellation of PMI once your LTV drops to 80% through payments or value gains.
- A larger down payment lowers LTV and often unlocks a better interest rate.
- When refinancing, a lower LTV usually means better terms, so time it accordingly.

Frequently asked questions
What's a good loan-to-value ratio?
For a home purchase, 80% or lower is a common target because it usually lets you avoid private mortgage insurance and can earn a better rate. Many loans allow higher LTVs, sometimes 95% or more, but a higher ratio typically means added costs and stricter approval.
How does LTV affect private mortgage insurance?
On a conventional loan, an LTV above 80% usually triggers private mortgage insurance, an added monthly cost that protects the lender. As you pay down the balance or the home's value rises, your LTV falls. At 80% you can often request to cancel PMI, and it's typically removed automatically at 78%.
Can I lower my LTV after buying?
Yes. Paying down your mortgage principal reduces the loan amount, and rising home value increases the denominator, both of which lower your LTV. A new appraisal showing higher value can help. A lower LTV may let you drop PMI or qualify for better terms when you refinance.
Knowing what Loan-to-Value Ratio (LTV) means is knowledge — the first half. A brick gets placed when you act on it: calculate your LTV to see how close you are to dropping mortgage insurance.
