Simple Interest Auto Loans 101
“Simple interest” is how most vehicle loans are structured. Instead of calculating interest yearly or monthly, simple interest gets calculated each day based on what you owe.
Meaning every payment you make goes towards the principal balance first… Then interest is calculated on the remaining amount.
Let that sink in for a second
The sooner you pay, the less interest you’ll accrue. But if you pay late (or don’t pay at all) that money still accrues interest until your next payment is due. For most borrowers this reality isn’t apparent until it’s too late.
Simple Interest’s Role in Your Payoff Timeline
Here’s the best part about simple interest auto loans.
If you understand how they work. You can pay off your vehicle loan much faster without any tricks or loopholes. Through providers like Exeter Finance, you can get the best out of your auto loan.
Because simple interest is calculated daily on your remaining balance. Making your payments early or putting extra money towards your principal each month reduces the amount you’ll pay in interest.
The lower your principal gets…
The less interest will be charged each day. Which means even more of your payment goes towards what you owe. It’s a cycle that can help you pay off your loan months earlier.
Of course, the opposite is true when borrowers fall behind on lenders. Suddenly, your interest will skyrocket because you haven’t made a payment, and your principal hasn’t been reduced. Vehicle loan restructuring may even come into play if you’re unable to make payments.
This is according to personal finance website MoneyUnder30 who reported that 11.85% of auto loans were past due as of December 2025. That means millions of Americans could be forced into restructuring if they don’t catch up on their payments.
Vehicle Loan Restructuring Explained
Wondering what happens when you can’t make your payments on time?
Enter vehicle loan restructuring.
Vehicle loan restructuring changes the terms of your existing auto loan. Whether it lengthens your repayment period, reduces your interest rate or adjusts your monthly payment. Restructuring is designed to give the borrower enough flexibility to keep making payments and prevent the lender from taking a loss on the vehicle.
Essentially, restructuring allows both parties to hit the reset button.
Loan restructuring doesn’t make the debt go away… it just rearranges it. And because simple interest loans calculate interest daily, when you restructure matters.
Extending your loan term through restructuring lowers your monthly payments. But it also gives the lender more time to charge you interest on your balance.
That’s why it’s crucial you understand simple interest before you jump into any restructuring agreements.
There are three main types of vehicle loan restructuring:
- Extending your loan’s term to lower monthly payments
- Negotiating a lower interest rate
- Postponing missed payments to the end of your loan
All three options will alter your payoff timeline. Getting your interest rate reduced is always best because you’re directly reducing how much interest accrues daily. Extending your loan term will give you more breathing room, but you’ll pay more overall. And postponing missed payments won’t change the interest equation at all.
How To Pay Off Your Simple Interest Loan Faster (5 ways)
Fortunately, there are things you can do to fight against interest and pay off your loan sooner. Whether you’re up to date on your payments or working from a restructured loan agreement.
Start Making Biweekly Payments
Make a payment every two weeks instead of once a month. Half of your normal monthly payment every other week equals 26 half payments. Which equals 13 full payments each year. That extra payment can shave months off your loan.
Round Up Payments
Round all of your payments to the nearest $50 or $100. It doesn’t sound like much but those extra dollars will reduce your principal balance faster. An extra $25 here and there adds up over time.
Get Into the Habit of Making Early Payments
Same concept as rounding up payments. Since simple interest accrues daily, putting your payment in a few days early will save you days of accrued interest. Every little thing you can do to lower your principal helps.
Apply Large Sum Payments To Principal
Got a tax return? Bonuses from work? Maybe some extra income from a side hustle. If you can apply those extra funds to your loan principal, you’ll be amazed at how much quicker you can pay off your loan. According to Experian, the average monthly payment for new cars in Q2 2025 was $749 with loan terms reaching 69 months. If you can cut 3-6 months off that with some extra payments, you’d be saving yourself hundreds if not thousands of dollars.
Refinance If You Can
Life hacks aren’t always the answer. If your credit score has improved since you first signed your loan agreement, consider refinancing into a lower rate.
The lower your interest rate, the less you’ll pay daily. And reducing that interest amount goes a long way towards paying off your loan faster.
One last thing: Make sure your extra payments are going towards your principal. Some lenders will move your next payment due date up if you don’t specify that your extra payments should be applied to principal.
Wrapping Things Up
Simple interest auto loans aren’t as difficult to understand as you might think. In fact, once you grasp how daily interest is calculated you’ll realize you have more control over your payoff timeline than you did before.
If you’re ahead of schedule on your loan, great! Keep doing what you’re doing. But if you’re behind on payments and researching vehicle loan restructuring, don’t lose hope. There are steps you can take to pay off your loan sooner.
