About the LTV Calculator
The loan-to-value ratio (LTV) compares a loan balance with the value of the property. Lenders use it to judge risk and set rates and mortgage insurance. CLTV adds second mortgages and HELOCs to the loan balance. Enter your home value and loan balances to see both ratios and your equity.
How to use it
- Enter the home value (or purchase price) and your first mortgage balance.
- Add any second mortgage or HELOC balance and the maximum CLTV your lender allows.
- Press Calculate LTV to see your ratios, equity and borrowing room.
LTV formula
LTV = loan balance ÷ property value × 100. A $315,000 loan on a $450,000 home is 70% LTV. CLTV = (all loan balances) ÷ property value.
What lenders look for
| LTV | What it usually means |
|---|---|
| 80% or lower | No PMI on conventional loans, better rates |
| 80% to 95% | PMI likely, rates slightly higher |
| Above 95% | Limited options; some programs allow it |
| Cash-out refinance | Often capped near 80% LTV |
Frequently asked questions
What is a good LTV ratio?
80% or lower is considered strong for conventional mortgages because it avoids PMI and usually earns better rates.
What is CLTV?
Combined loan-to-value adds all loans secured by the home, such as a second mortgage or HELOC, to your first mortgage before dividing by the home value.
How do I lower my LTV?
Pay down the loan, make a larger down payment on a new purchase or wait for your home value to rise.
Does LTV use purchase price or appraised value?
Lenders use the lower of the purchase price and appraised value on a purchase, and the appraised value on a refinance.
How much can I borrow with a HELOC?
Most lenders allow a combined LTV of 80% to 90%. Use the room shown above as a rough guide.
