Debt Consolidation Savings Calculator公式

## Debt Consolidation

Consolidation replaces multiple high-rate debts with a single lower-rate loan.

### When It Makes Sense

- Your new rate is significantly lower than your current average rate
- You will NOT run up new debt on the freed credit cards
- The total cost (including fees) is less than your current path

### Formula

Both scenarios use the standard loan payment formula:

**M = P x r x (1+r)^n / [(1+r)^n - 1]**

The difference in total interest between old and new rates is your savings.

计算示例

$25,000 at 22% average vs consolidation at 10% for 5 years.

  1. New payment = $25,000 at 10% for 60 months = $531
  2. New total interest = $531 x 60 - $25,000 = $6,874
  3. Old total interest at 22% = $707 x 60 - $25,000 = $17,418
  4. Interest savings = $17,418 - $6,874 = $10,544
