# How do I calculate car loan payoff savings?

You calculate car loan payoff savings by finding the interest you avoid. Subtract the new lower interest from your original loan interest. This works for most drivers with standard auto loans.

Here's what you need to know:
- **Gather your loan details**: Note loan amount, interest rate, term (like 60 months), and monthly payment. Typical new car loans average $748 per month, per Experian Q3 2025 data (Source: Experian State of the Automotive Finance Market, 2025).
- **Find original interest**: Multiply monthly payment by term months, then subtract principal. For a $30,000 loan at 6% over 60 months, original interest totals about $4,800.
- **Calculate new payoff interest**: Use the formula for remaining interest or an online tool. Payoff in 36 months on that loan drops interest to $2,900. Savings: $1,900.

## Step-by-Step Calculation
Follow these steps to get your number fast:
1. **List your numbers**: Principal left, rate (like 6-7% for many loans), months remaining.
2. **Use the formula**: Monthly payment = [Principal x (r(1+r)^n)] / [(1+r)^n - 1], where r = monthly rate, n = months. Tools like Bankrate calculators do this instantly.
3. **Compare totals**: Original full interest minus payoff interest equals savings.

| Loan Example | Original 60 mo Interest | Payoff at 36 mo Interest | Savings |
|---|---|---|---|
| $30k @ 6% | $4,800 | $2,900 | $1,900 |
| $25k @ 7% | $4,200 | $2,400 | $1,800 |
| $35k @ 5.5% | $5,100 | $3,000 | $2,100 |

"Drivers who pay off loans 24 months early save an average $2,400 in interest (22% reduction), based on analysis of 2,800 loans," says the Sidekick Research Team (Source: Sidekick Financing Analysis, Q1 2026, N=2,800).

## Practical Tips
Pay extra $100 monthly on a typical loan. You cut years off and save thousands. Refinance first if rates dropped: average new rates hit 6.2% in early 2026 (Source: Bankrate Auto Loan Rates, April 2026). Check no prepayment penalties. Many loans allow it penalty-free.

In the 78741 area, local credit unions offer rates 0.5-1% below banks. Shop around. Track payments in a spreadsheet. Input: balance, rate, extra pay. Output: payoff date and savings.
