## How to Calculate Refinance Savings

Refinancing replaces your current loan with a new one at a lower rate.

### Savings Formula

**Monthly Savings = Current Payment - New Payment**

**Total Savings = Monthly Savings x Number of Payments**

Both payments use the standard amortization formula with respective interest rates.

Lösungsbeispiel

Refinancing a $40,000 loan from 6.8% to 4.5% over 10 years.

  1. Current monthly payment at 6.8% = $460.32
  2. New monthly payment at 4.5% = $414.02
  3. Monthly savings = $460.32 - $414.02 = $46.30
  4. Total savings over 10 years = $46.30 x 120 = $5,556
