What you can do right now to reduce what you owe each month
The most direct ways to lower a car payment are to refinance your loan at a better interest rate, extend the length of your loan, or pay a lump sum toward the principal. Refinancing works best if your credit score has improved since you took out the original loan, or if interest rates have dropped. Extending your loan means spreading the same amount of money over more months, which reduces each payment but costs you more in total interest. A lump sum payment — even $500 or $1,000 if that is what you have — reduces the amount you still owe, which lowers future payments if you refinance.
Some of these options cost money upfront or cost you more overall. Others require your lender's agreement or a new lender's approval. Understanding what each route involves helps you pick the one that actually fits your situation, rather than the one that sounds easiest.
Key Takeaways
- Refinancing to a lower interest rate reduces your payment without changing how long you owe money, but requires a credit check and approval from a new lender.
- Extending your loan term lowers the monthly payment when ready but means paying more interest over the life of the loan.
- Paying a lump sum toward the principal reduces what you owe, which lowers your payment if you refinance or renegotiate with your current lender.
- Your current lender may modify your loan without refinancing, though this is less common than it was during the pandemic.
- Selling the car and buying a cheaper one or using public transit eliminates the payment entirely but requires significant change to your situation.
Refinancing to a lower interest rate
Refinancing means taking out a new loan to pay off your old one. The new lender pays your current lender in full, and you start making payments to the new lender instead. This only makes sense if the new interest rate is lower than what you are currently paying — the savings have to be large enough to cover any fees the new lender charges.
Your interest rate depends mainly on your credit score. If your score has gone up since you first borrowed — because you have paid bills on time, paid down other debts, or fixed errors on your credit report — you may now may have access to for a better rate. You can check your credit score free once a year at annualcreditreport.com, or through many banks and credit card companies.
Banks, credit unions, and online lenders all offer car refinancing. Credit unions often have lower rates than banks, especially if you are a member. Getting quotes from at least three lenders takes about 15 minutes per lender and does not hurt your credit score — multiple inquiries for the same type of loan within 14 days count as one inquiry. Compare the interest rate, any fees (some lenders charge origination fees or prepayment penalties), and the monthly payment.
Refinancing typically takes one to two weeks from approval to funding. During that time, you keep making payments to your current lender as usual.
Extending your loan term to lower the monthly payment
If you currently owe $15,000 on a five-year loan, your monthly payment is higher than if you spread that same $15,000 over seven years. Extending the term — the length of time you have to repay — divides the debt into smaller pieces.
The catch is that you pay more interest overall. A longer loan means more months of interest charges. If you refinance into a seven-year loan instead of a five-year loan at the same interest rate, you might lower your payment by $100 a month but pay $2,400 more in total interest. Whether that trade-off makes sense depends on whether you need that $100 a month to cover other expenses right now.
You can extend your term by refinancing with a new lender who offers longer terms, or by asking your current lender if they will modify your loan. Some lenders will extend a loan without refinancing, though this is less common now than it was in 2020 and 2021. Call your lender's customer service number — it is on your loan statement — and ask whether loan modification is an option.
Making a lump sum payment toward what you owe
Paying $1,000, $2,000, or whatever amount you can afford directly reduces the principal — the amount you still owe. This does not when ready lower your monthly payment, but it does reduce the total amount you are paying interest on.
If you then refinance, the new loan is for a smaller amount, which means a lower monthly payment. For example, if you owe $20,000 and pay $3,000 toward it, you now owe $17,000. Refinancing that $17,000 will result in a lower payment than refinancing the original $20,000.
Before making a lump sum payment, check whether your loan has a prepayment penalty — a fee some lenders charge if you pay off the loan early. Your loan documents should say whether one exists. If there is no penalty, you can pay extra toward the principal at any time, usually by sending a check to your lender or paying online and specifying that the payment goes toward principal rather than the next month's payment.
Asking your current lender to modify your loan
Some lenders will modify an existing loan without requiring you to refinance with a new lender. This might mean extending the term, lowering the interest rate, or skipping a payment in hardship situations. Modifications are less common now than they were during the pandemic, but they are worth asking about.
Call the customer service number on your loan statement and explain your situation honestly. If you are struggling to make the payment, say that. If your credit has improved and you think you deserve a better rate, say that too. The lender has no obligation to modify the loan, but some will, especially if you have been a reliable customer.
If the lender agrees to modify your loan, get the new terms in writing before you sign anything. Make sure you understand the new payment amount, the new term length, and whether there are any fees.
Selling the car and finding a cheaper alternative
If your car payment is genuinely unaffordable and none of the above options work, you can sell the car and buy a cheaper one outright, or use public transit, carpooling, or a bike instead. This is a major change and not realistic for everyone, but it is worth considering if you are in a situation where the payment is pushing you into debt.
If you owe more than the car is worth — called being "underwater" on the loan — you cannot straightforward sell it and walk away. You would have to pay the difference out of pocket. You can find out what your car is worth by checking Kelley Blue Book or NADA Guides with your car's year, make, model, and mileage. If you owe $18,000 and the car is worth $15,000, you are underwater by $3,000.
If you are not underwater, you can sell the car privately or trade it in at a dealership. The money from the sale goes to your lender first to pay off what you owe, and any leftover money goes to you. You then have no car payment, though you also have no car.
Comparing your options side by side
| Option | How it works | Time to lower payment | Cost to you |
|---|---|---|---|
| Refinance at lower rate | New lender pays off old loan; you pay new lender | 1–2 weeks | Possible origination fee; saves money if rate is lower |
| Extend loan term | Spread same debt over more months | 1–2 weeks (if refinancing) or when ready (if lender modifies) | More interest paid overall |
| Lump sum payment | Pay down principal; refinance for lower payment | 1–2 weeks after lump sum | The lump sum amount; possible prepayment penalty |
| Loan modification | Current lender changes terms without refinancing | A few days to a week | Usually none, but varies by lender |
| Sell the car | Sell car; pay off loan; use other transportation | when ready after sale | Loss of car; possible out-of-pocket if underwater |
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard inquiry from a lender will lower your score by a few points temporarily, but the effect fades within a few months. Multiple inquiries for car loans within 14 days count as one inquiry, so getting quotes from several lenders does not multiply the damage. Your score may actually improve over time if refinancing lowers your overall debt or improves your payment history.
What if I have bad credit and cannot refinance?
Refinancing is harder with a low credit score, but not impossible — some lenders specialize in bad-credit auto refinancing, though their rates are higher. Your better option is usually to focus on the other strategies: ask your current lender about modification, make a lump sum payment if you can, or extend your term through your current lender if they offer it.
Can I refinance if I still owe more than the car is worth?
Yes, but it is harder. You are "underwater" on the loan, and most lenders will not refinance an underwater car because the car is not worth enough to cover the loan if you default. Some credit unions and specialized lenders will do it, but at a higher interest rate. Your best option is usually to make a lump sum payment first to get above water, then refinance.
How much will refinancing save me?
That depends on your current interest rate, your new interest rate, how much you owe, and how long you have left on the loan. A calculator on your lender's website can show you the savings. As a rough example, refinancing $15,000 from 8% to 5% over the same remaining term might save you $50 to $100 a month, but the exact number is different for every loan.
What happens if I cannot afford my payment even after lowering it?
Contact your lender when ready and explain your situation. Many lenders have hardship programs that can pause payments, extend your loan, or work out a temporary arrangement. Ignoring the problem leads to late fees, damage to your credit, and eventually repossession. Talking to your lender early gives you more options.
