Loan-to-Value (LTV) Ratio Calculator
Use this calculator to estimate your LTV ratio, equity, and optional CLTV if you have a second mortgage or HELOC.
Tip: You can enter plain numbers or values with commas (example: 425,000).
What is Loan-to-Value (LTV) Ratio?
The loan-to-value ratio (LTV) compares your mortgage balance to your home’s current value. Lenders use it to evaluate risk when approving a purchase, refinance, or home equity loan. A lower LTV usually means less risk for the lender, which can help you qualify for better rates and lower fees.
Example: If your loan amount is $300,000 and your property value is $400,000, your LTV is 75%.

Why LTV Matters to Mortgage Lenders
LTV affects almost every part of mortgage underwriting:
- Approval odds: Lower LTV can improve your qualification profile.
- Interest rate: Lower risk often leads to better pricing.
- Mortgage insurance: Conventional loans above 80% LTV often require PMI.
- Cash-out limits: Refinance programs cap maximum LTV.
- Equity access: Home equity loans and HELOC approvals often depend on CLTV limits.
Common LTV Limits by Loan Type
| Loan Type | Typical Maximum LTV | Notes |
|---|---|---|
| Conventional | Up to 97% | PMI generally required above 80% LTV. |
| FHA | Up to 96.5% | Mortgage insurance premiums apply. |
| VA | Often up to 100% | No monthly PMI, but eligibility rules apply. |
| USDA | Up to 100% | Rural and income eligibility requirements. |
| Cash-Out Refinance | Commonly 80% (varies) | Program and lender overlays can reduce this. |
LTV vs. CLTV: What’s the Difference?
LTV (Loan-to-Value)
Only includes your first mortgage balance compared with the property value.
CLTV (Combined Loan-to-Value)
Includes all loans secured by the property (first mortgage + second mortgage + HELOC). CLTV is especially important when you have multiple liens and want to refinance or borrow against equity.
Three Quick Examples
1) Purchase with 20% down
Home price: $500,000 | Loan: $400,000 → LTV = 80%
2) Refinance with high equity
Home value: $450,000 | Balance: $270,000 → LTV = 60%
3) Two loans on the property
Value: $400,000 | First mortgage: $280,000 | HELOC: $40,000 → LTV = 70%, CLTV = 80%
How to Improve Your LTV Ratio
- Make extra principal payments on your mortgage.
- Increase your down payment before buying.
- Wait for principal reduction over time.
- Renovate strategically to potentially improve appraised value.
- Review whether a new appraisal is appropriate for refinance.
Frequently Asked Questions
Is a lower LTV always better?
Generally yes. Lower LTV means more equity and lower lender risk. It can improve loan pricing and reduce insurance costs.
What is considered a good LTV ratio?
Many borrowers target 80% or lower to avoid PMI on conventional loans, but “good” depends on your loan type and goals.
Can LTV be over 100%?
Yes. If your loan balance is higher than your home value, your LTV exceeds 100%, often called being “underwater.”
Do lenders use appraised value or market estimate?
Most lenders rely on an official appraisal (or approved valuation method), not just online estimate tools.
