When Should You Refinance Your Auto Loan?
Refinancing makes sense in several scenarios:
Interest Rates Have Dropped
If market rates have decreased since you financed your vehicle, refinancing can lock in savings. Even a 1-2% reduction can save thousands over the loan term.
Your Credit Has Improved
Made consistent on-time payments for 6-12 months? Your improved credit score could qualify you for significantly better rates. Many borrowers refinance after repairing their credit.
You Want Lower Monthly Payments
Extending your loan term can reduce monthly payments, freeing up cash flow. However, longer terms mean more interest paid overall—calculate the total cost before deciding.
You’re Paying Too Much Interest
If your current APR is above 8%, you’re likely paying too much. Shop around to see if you can reduce your rate and total interest paid.
You Want to Remove a Co-Signer
Once your credit and income can support the loan independently, refinancing lets you remove a co-signer and take full ownership.
How Much Can You Save by Refinancing?
According to Experian data from Q3 2025:
- Average interest rate reduction: 2.08%
- Average monthly payment savings: $77
- Savings by lender type: Credit unions ($95/month), Banks ($56/month), Finance companies ($18/month)
On a $25,000 loan with 48 months remaining at 8% APR, refinancing to 6% APR saves you approximately:
- Monthly payment reduction: $30
- Total interest savings: $1,440 over the loan term
Use online refinance calculators to estimate your specific savings based on your current loan balance, interest rate, and remaining term.
Tips for Getting the Best Refinance Rate
Shop Multiple Lenders Within 14 Days
Credit scoring models treat multiple auto loan inquiries within a 14-day window as a single inquiry. This protects your credit score while you comparison shop.
Wait 6-12 Months Before Refinancing
If you recently financed with poor credit, wait at least six months of on-time payments before refinancing. This builds positive payment history and may improve your credit score.
Know Your Vehicle’s Value
Understanding your car’s current value helps you calculate your loan-to-value ratio. Most lenders require LTV below 125%, and better rates come with lower LTV.
Check for Prepayment Penalties
Before refinancing, review your current loan agreement for prepayment penalties. These fees can offset refinancing savings.
Consider Total Cost, Not Just Monthly Payment
Lower monthly payments are tempting, but extending your term significantly increases total interest paid. Balance affordability with long-term cost.
Gather Required Documents
Prepare these documents in advance to speed up the application:
- Current loan statement with payoff amount
- Proof of income (pay stubs, tax returns)
- Proof of insurance
- Vehicle registration
- Driver’s license
- Residence verification
Frequently Asked Questions
How soon can I refinance my car loan?
Technically, you can refinance immediately after purchasing, but most experts recommend waiting at least 6-12 months. This allows you to build positive payment history and gives your credit score time to recover from the initial purchase.
Will refinancing hurt my credit score?
A hard inquiry causes a small temporary drop (typically 5-10 points), but responsible management of your new loan can improve your score long-term. Multiple inquiries within 14-45 days count as a single inquiry for scoring purposes.
Can I refinance an upside-down car loan?
Yes, some lenders like PenFed will refinance up to 125% of your vehicle’s value. However, being underwater limits your options and may result in higher interest rates.
What credit score do I need to refinance?
Most mainstream lenders require 600+, but some like OpenRoad Lending accept scores as low as 460. Better credit (700+) qualifies for the lowest rates, often below 5% APR.
How long does the refinancing process take?
Online lenders like LightStream can fund in 1-2 days, while credit unions may take 1-2 weeks. The application itself typically takes 15-30 minutes.
Should I refinance with my current lender?
Maybe. Your current lender may offer a loyalty discount, but you’ll only know if it’s competitive by shopping around. Don’t assume they’ll give you their best rate automatically.
Can I refinance a leased vehicle?
Not directly, but you can use a lease buyout loan through lenders like AUTOPAY. This purchases the vehicle at the residual value stated in your lease agreement.
What if my car is too old or has too many miles?
Each lender has different restrictions. While some cap at 7-10 years old with 100,000 miles, others like myAutoloan accept vehicles up to 10 years old with 125,000 miles.
