EV Loan Monthly Payment Calculator
Work out your monthly payment, total interest and total cost on an EV loan.
How auto loans work
An auto loan is a fixed-payment loan amortized over a number of months. Each payment covers some interest (a percentage of the remaining balance) and some principal. As the balance shrinks, more of each payment goes to principal, and less to interest.
Where P is the amount financed (price minus down payment), r is the monthly interest rate (APR ÷ 12), and n is the term in months.
Worked example
A $35,000 EV with $5,000 down on a 6.5% APR, 60-month loan finances $30,000. Monthly payment works out to about $587; total interest over the life of the loan is about $5,220.
Tips for EV-specific financing
- Apply the federal tax credit first. If you qualify for the $7,500 clean vehicle credit and the dealer transfers it at point of sale, your financed amount drops by $7,500 immediately.
- Shop the rate. Credit unions and online lenders typically beat dealer financing by 1–2 percentage points. On a $30k loan that’s $1,500–3,000 of interest saved.
- Shorter term = less interest, higher payment. A 48-month loan costs roughly half the interest of a 72-month loan on the same car.
- Don't roll a negative. Avoid financing more than the car is worth (negative equity at trade-in is painful).
This calculator handles principal and interest only. Your actual monthly bill may add taxes, registration, gap insurance and dealer add-ons — ask for an out-the-door price.
Frequently asked
How does an auto loan actually work?
A standard auto loan is amortized — each fixed monthly payment covers some interest (on the remaining balance) and some principal. Early payments are mostly interest; late payments are mostly principal. By the end you have paid the full price plus total interest.
What is a good APR on an EV loan in 2026?
Excellent credit (750+) currently sees 5.5–7%. Average credit (670–749) is 7–9%. Below 670 you might see 10%+. Credit unions and online lenders often beat dealer financing by 1–2 percentage points — worth shopping.
Should I take the dealer's financing?
Get pre-approved by a credit union or bank first, then see if the dealer can beat it. Some dealers offer manufacturer-subsidized "promotional" rates (0–3%) on specific models — those are worth taking when available. Otherwise, third-party financing usually wins.
How does the federal tax credit fit into financing?
If you transfer the $7,500 credit at point of sale (introduced in 2024), the dealer applies it as a down payment immediately — reducing the amount financed by $7,500. Otherwise you wait to claim it on your next tax return, which does not help your monthly payment.
Does the loan term affect total cost a lot?
Significantly. A 48-month loan vs a 72-month on the same $30k principal at 7%: monthly payment goes from $718 to $511, but total interest paid goes from $4,460 to $6,805. Longer terms feel cheaper monthly but cost more overall.
