The used Tesla depreciation math shows you're better off buying new, especially when Model Y 1.49% financing is on the table.
I lost $40k to $50k on lightly used Teslas before realizing the obvious. The numbers just don't work when you factor in higher interest rates and lost incentives.
Why the math favors new every time
Mike nailed it when he said there's almost never a good reason to buy a 1-2 year old lightly used Tesla unless it's saving more than $4,000 in incentives. You'll walk into a new one with full factory warranty, manufacturer incentives, and lower rates.
Right now 2024-2025 Model Ys sit in the $35k-$38k range used. A brand new premium RWD Model Y starts at $48k while the standard version is $40k. Both qualify for 1.49% financing. Used examples often carry 5-6% rates instead.
Tesla new vs used financing breakdown
Take a $50k new Model Y at 1.49% with $10k down over 72 months. Monthly payment lands at $581 and total cost hits $57k with only $1,839 in interest.
Compare that to a $36k used Model Y at 6% with the same down payment. Monthly comes in lower but total cost reaches $45k and interest balloons to $5k. The gap widens fast once you add lost warranty coverage and no buyback protection.

Counterarguments and when used might tempt you
Some buyers point to the lower sticker price as obvious savings. Cash buyers can sometimes make the numbers work. Yet most people finance, which flips the equation against used inventory.
2026 Model Ys listed near $46k-$47k make even less sense. You're paying near-new money for a vehicle that's already depreciated without the low-rate financing or full warranty.
My conclusion on Tesla buy new vs used
The combination of 1.49% financing, full warranty, and potential buyback protection makes new the clear winner for me. I've used the buyback program myself after a major issue and it let me reset into a fresh vehicle.
If you're shopping Model Y right now, the Tesla referral — 3 months free FSD + low APR financing unlocks the current rate plus free Full Self-Driving for three months. Learn exactly how to qualify in this guide.
I'd go new every single time over a 1-2 year old used Tesla.
