How to Pay Off Your Car Loan Early (and Save on Interest)

The average car loan interest rate in 2024 is around 7–9% for new cars and 10–14% for used. On a $25,000 loan over 60 months at 9%, you'd pay over $6,000 in interest alone. Paying off that loan early cuts straight into that number.

Step 1: Check for Prepayment Penalties

Before throwing extra money at your car loan, read the loan agreement or call your lender. Some lenders charge a prepayment penalty — a fee for paying off the loan early. These are less common than they used to be but still exist. If the penalty is large, it may not be worth paying off early.

Most major banks and credit unions do NOT charge prepayment penalties on auto loans, but smaller finance companies or dealer-arranged financing sometimes do.

Step 2: Make Biweekly Payments Instead of Monthly

Instead of one payment per month, pay half that amount every two weeks. Because there are 52 weeks in a year, you'll make 26 half-payments — the equivalent of 13 full monthly payments instead of 12. That one extra payment per year can shorten a 60-month loan by 4–6 months and save hundreds in interest.

Step 3: Make Extra Principal Payments

Any extra money you apply directly to principal reduces the balance on which interest is calculated. Even small amounts add up:

• Round up your payment: paying $350 instead of $287 adds $63/month to principal
• Apply windfalls: tax refunds, bonuses, or cash gifts applied to the loan balance
• One extra full payment per year toward principal

On a $20,000 loan at 8% over 60 months, paying an extra $100/month reduces the loan term by about 14 months and saves nearly $1,000 in interest.

Step 4: Refinance to a Lower Rate First

If your credit score has improved since you took out the loan, refinancing might get you a lower rate — then you can pay extra on top of that. Refinancing from 12% to 7% on a $15,000 balance saves thousands before you even start making extra payments.

Should You Pay Off Your Car Loan Early?

Early payoff makes sense when:

• Your interest rate is above 6% — that's a guaranteed return on paying it down
• You have no high-interest credit card debt (pay those first)
• You have a 3–6 month emergency fund already in place
• Freeing up the monthly payment would significantly improve your cash flow

It may not make sense when: your rate is below 4% (investing that money might return more), or you'd deplete your emergency fund to do it.

After Payoff: What to Do With the Extra Cash

The moment your car is paid off, resist lifestyle creep. Redirect that monthly payment into your emergency fund, retirement account, or the next debt on your payoff list. Paying off a car that cost $400/month frees up $4,800 per year — that's a meaningful wealth-building opportunity.
