Auto Loan Hidden Cost Revealer
Tesla Model 3 Auto Loan True Cost Calculator
The monthly payment on a Tesla Model 3 is only the opening number. The real question is how much of your income the loan consumes and what the total interest costs over the full term. This calculator pre-fills the Tesla Model 3's starting MSRP of $36,990 — the manufacturer's price for the base trim, before destination, tax and dealer charges — and the national average new-car loan rate, so you can see the total financed cost in seconds.
What the number means
On a Tesla Model 3 at its $36,990 starting MSRP, financed at 7.14% over 72 months, the interest alone can add thousands to the total cost. The calculator breaks this into the car price, the interest, and the total amount you will actually pay — plus the working hours that total represents.
Why this matters
Auto loans are one of the largest monthly obligations most people take on. Stretching the term to 72 or 84 months lowers the monthly payment but quietly increases the total interest. Seeing the full number before you sign keeps the dealer focused on the total price, not just the payment.
How to use this page
Change the price, down payment, APR, or term to match your actual quote. Two of these numbers move once you are in the showroom: destination, options and dealer fees land on top of MSRP, and the rate you are offered depends on your credit score and term. Your quote is the number that matters, and typing it in replaces every figure here. The numbers update instantly in your browser. No information is saved or sent.
At $36,990, the Tesla Model 3 lands in the mid-priced band: a 10% down payment is $3,699, and the monthly figure clears the common 15%-of-take-home guardrail only on a comfortably middle income. Check it against your own paycheck with the car payment vs income calculator before the test drive, not after.

Common questions
What is the monthly payment on a Tesla Model 3?
About $570 a month, on a $36,990 price with $3,699 down — a 10% deposit — financed at 7.14% APR over 72 months. That leaves $33,291 borrowed. Change any of those in the calculator above and the payment updates as you type.
How much interest does a Tesla Model 3 loan actually cost?
$7,736 over the full 72 months. The car costs $36,990; you hand over $44,726 by the end. That gap is what the loan costs you, and it does not appear anywhere on the monthly payment the dealer quotes.
Is a longer term cheaper?
The payment is smaller and the loan is dearer. Stretching this 72-month loan to 84 months drops the payment to $505 but raises the interest to $9,106, $1,370 more. Shortening it to 60 months costs $661 a month and $6,393 in interest — $1,343 less than the 72-month version.
How much does a bigger down payment save?
Going from 10% down to 20% on a $36,990 Tesla Model 3 — $7,398 instead of $3,699 — cuts the payment to $507 and the interest to $6,876. That is $860 saved for $3,699 paid up front.
Figures assume a $3,699 down payment (10%) on the $36,990 starting MSRP at 7.14% APR over 72 months, the values this page loads with.
