Formula Explained

The auto loan payoff calculator uses the following formula to determine your savings:

Payoff Calculation Formula

Total Interest Saved = Original Total Interest - New Total Interest

Where:

  • Original Total Interest = Loan Balance × (Interest Rate / 100) × (Original Term / 12)
  • New Total Interest = Loan Balance × (Interest Rate / 100) × (New Term / 12)
  • New Term = Original Term - (Extra Payment / Monthly Payment)

This formula accounts for the reduced interest charges when you pay off your loan early with extra payments.

Worked Example

Let's say you have a $20,000 auto loan with a 5% annual interest rate and a 48-month term. Your monthly payment is $458.33.

If you make an extra $200 per month, your new term will be 36 months (48 - (200/458.33)).

Original total interest: $20,000 × (0.05/12) × 48 = $4,800

New total interest: $20,000 × (0.05/12) × 36 = $3,600

Total interest saved: $4,800 - $3,600 = $1,200

You'll save $1,200 in interest and pay off your loan 12 months early.

Auto Loan Payoff Strategies

There are several strategies to pay off your auto loan early:

  1. Extra Payments: Make larger payments than required each month.
  2. Bi-Weekly Payments: Pay every two weeks instead of monthly.
  3. Refinance: Get a lower interest rate to save on interest.
  4. Balloon Payments: Make smaller payments and pay off the balance at the end.

Important Note

While paying off your auto loan early can save you money, be aware that refinancing may have fees and closing costs. Always compare the total cost before making a decision.
