The **Loan to Value Ratio (LTV) Calculator** is essential for determining the ratio between the mortgage loan amount and the appraised value of the property. Lenders use LTV to assess risk, which dictates interest rates and whether Private Mortgage Insurance (PMI) is required. Enter values for any three of the four core parameters (Loan Amount, Property Value, LTV Ratio, or Down Payment) to solve for the missing one.

LTV Parameters
LTV Ratio Formula
The Loan-to-Value Ratio ($LTV$) is calculated by dividing the Loan Amount ($L$) by the Appraised Property Value ($V$). The result is then multiplied by 100 to express it as a percentage.
LTV Ratio (%):
$$LTV = \frac{L}{V} \times 100$$Down Payment ($D$):
$$D = V – L$$ Formula Source: InvestopediaVariables Explained (P, F, V, Q – Parameters)
- $L$ (Loan Amount, $P$): The total amount of money borrowed for the mortgage.
- $V$ (Property Value, $F$): The appraised market value of the property.
- $LTV$ (LTV Ratio, $V$): The percentage of the property’s value that is financed by the loan.
- $D$ (Down Payment, $Q$): The cash amount paid upfront, equal to the difference between property value and loan amount.

What is Loan to Value Ratio?
The **Loan-to-Value (LTV) Ratio** is a critical metric used by mortgage lenders to assess the level of risk associated with a loan. It compares the amount of the mortgage loan to the appraised value of the property securing the loan. LTV is typically expressed as a percentage. The higher the LTV, the riskier the loan is considered, as the borrower has less equity in the property.
The LTV ratio directly influences the terms of your mortgage. For example, an LTV above 80% usually requires the borrower to pay Private Mortgage Insurance (PMI) until the LTV drops below 80%. Conversely, a lower LTV, such as 60% or less, often qualifies the borrower for better interest rates and easier approval processes.
How to Calculate LTV Ratio (Example)
A home is appraised at \$400,000, and the borrower takes out a loan of \$320,000. We solve for the LTV Ratio ($LTV$):
- Step 1: Identify Loan Amount and Property Value
$L = \$320,000$ and $V = \$400,000$.
- Step 2: Apply the LTV Formula
$LTV = (L / V) \times 100 = (\$320,000 / \$400,000) \times 100 = \mathbf{80\%}$.
- Step 3: Calculate Down Payment ($D$)
$D = V – L = \$400,000 – \$320,000 = \mathbf{\$80,000}$.
The LTV is $\mathbf{80\%}$. In this scenario, the borrower would typically need to pay PMI, as the ratio is not below the 80% threshold.
Frequently Asked Questions (FAQ)
For conventional loans, the maximum LTV is usually 95% (requiring a 5% down payment). FHA loans can go up to 96.5%, and VA loans can be 100% (LTV of 100%).
An LTV above 80% is considered higher risk, and the lender will typically require the borrower to pay Private Mortgage Insurance (PMI), which adds to the monthly cost but protects the lender, not the borrower.
Lenders use the lesser of the purchase price or the appraised value. If you purchased the property for less than its appraised value, the appraised value will often be used to calculate a lower, more favorable LTV.
Generally, the lower the LTV ratio, the lower the interest rate you will be offered, as a low ratio signals less risk to the lender.
