贷款价值比计算器公式

## Loan-to-Value Ratio Explained

LTV measures how much of the property value is financed, and is a key factor in lending decisions.

### Formula

**LTV = (Loan Amount / Appraised Value) x 100**

### LTV Thresholds

- Below 80%: Typically no PMI required
- 80-95%: PMI usually required for conventional loans
- Above 95%: Higher-risk territory, limited loan options
- Above 100%: Underwater (owe more than property is worth)

计算示例

A borrower has a $280,000 loan on a property appraised at $350,000.

  1. LTV = $280,000 / $350,000 = 0.80
  2. LTV = 80.00%
  3. Equity percentage: 100% - 80% = 20.00%
  4. Equity amount: $350,000 - $280,000 = $70,000
  5. At 80% LTV, PMI is typically not required
