Introduction
The LTV Calculator helps you find your loan-to-value ratio in seconds. LTV is a simple number that compares how much you owe on your home to how much your home is worth. Lenders use this ratio to decide if you qualify for a mortgage, home equity loan, or refinance. A lower LTV means you own more of your home and carry less risk. A higher LTV means you owe more and may need to pay for private mortgage insurance (PMI).
This calculator has two modes. Standard mode takes your property value and loan balances, then shows your current LTV ratio, home equity, and a side-by-side comparison of different LTV targets. Reverse mode works the other way — you pick a target LTV, and the calculator tells you the maximum loan amount you can borrow. Both modes include clear charts and tables so you can see exactly where you stand.
Whether you are buying your first home, thinking about a second mortgage, or planning to refinance, knowing your LTV ratio is one of the most important steps you can take. Enter your numbers below to get started.

Calculation Mode: Pick "Standard LTV" to find your current LTV ratio. Pick "Reverse LTV" to find the maximum loan amount for a specific LTV target.
Appraised / Market Property Value: Enter what your home is worth today. Use a recent appraisal or your best estimate of the current market value.
Outstanding First Mortgage Balance: Enter how much you still owe on your main home loan. You can use a mortgage payoff calculator to find your current balance. This shows in Standard mode only.
Outstanding Second Mortgage Balance: Enter how much you owe on a second loan, such as a home equity loan or HELOC. Leave it at zero if you do not have one. This shows in Standard mode only.
Target LTV Percentage: Enter the LTV ratio you want to reach. The calculator will tell you the maximum loan amount for that target. This shows in Reverse mode only.
Multi-Scenario LTV Comparison Targets: Enter up to four LTV percentages to compare side by side. The calculator will show how much credit is available and how much equity remains at each target. This shows in Standard mode only.

What Is a Loan-to-Value (LTV) Ratio?
The loan-to-value ratio, or LTV, tells you how much of your home's value is covered by your loan. It compares what you owe on your mortgage to what your property is worth. Lenders use this number to decide how risky a loan is before they approve it.
How to Calculate LTV
To find your LTV, divide your total loan balance by your home's current market value, then multiply by 100. For example, if your home is worth $300,000 and you owe $240,000, your LTV is 80%. A lower LTV means you own more of your home and owe less. You can also use a percentage calculator to quickly work through the math.
Why LTV Matters
Your LTV ratio affects several important things. If your LTV is above 80%, most lenders will require you to pay for private mortgage insurance (PMI), which adds to your monthly costs. A high LTV can also mean a higher interest rate on your loan. When you refinance or apply for a home equity loan, lenders check your LTV to see how much they can safely lend you. Your LTV also plays a role alongside your debt-to-income (DTI) ratio in determining overall loan eligibility.
What Is a Good LTV Ratio?
An LTV of 80% or lower is considered low risk. This means you have at least 20% equity in your home. An LTV between 80% and 95% is moderate risk, and anything above 95% is high risk. The lower your LTV, the better your chances of getting approved for a loan with good terms. If you are buying a home and want to see how much you need to put down to reach a target LTV, try using a down payment calculator. To see whether buying makes financial sense for your situation, a rent vs buy calculator can help you compare options.
Combined LTV (CLTV)
If you have more than one loan on your property, such as a first mortgage and a home equity line of credit, lenders look at your combined LTV. This adds up all your loan balances and divides the total by your property value. This calculator handles both a first and second mortgage so you can see your true combined LTV. To understand how your full monthly housing cost breaks down, including principal, interest, taxes, and insurance, you can use a PITI calculator.
Reverse LTV: Finding Your Maximum Loan
Sometimes you want to know the opposite — how much you can borrow at a certain LTV. The reverse LTV mode in this calculator does exactly that. You enter your property value and your target LTV percentage, and it shows you the maximum loan amount you can take out while staying at or below that limit. Once you know your maximum loan amount, you can use a loan calculator to estimate monthly payments, or an amortization calculator to see how principal and interest break down over time. If you are considering a specific loan type, tools like the FHA loan calculator or VA loan calculator can provide tailored estimates.
