Example Calculation

Let’s see an example using this calculator:

Current Loan Amount: $15,000
Current Interest Rate: 7% per year
Remaining Loan Term: 36 months
New Refinance Rate: 4% per year
New Loan Term: 36 months

Step 1: Calculate Current Monthly Payment
Using standard amortization formulas, the current monthly payment is approximately $463.16.

Step 2: Calculate New Monthly Payment
After refinancing at 4% interest, the new monthly payment is approximately $443.21.

Step 3: Calculate Total Interest Saved
Total interest on the current loan: $463.16 × 36 − $15,000 = $1,673.76
Total interest on the new loan: $443.21 × 36 − $15,000 = $955.56
Interest Saved: $1,673.76 − $955.56 = $718.20

Step 4: Total Payment Difference
Total payments now vs. new payments: $16,673.76 − $15,955.56 = $718.20

By refinancing, you save $718.20 in interest and reduce your monthly payment by about $20.
