2021 Tesla Model Y: True Cost of Ownership (5-Year Breakdown)
The 2021 Tesla Model Y Long Range or Standard Range is a compact electric SUV that blends impressive technology with low running costs, making it ideal for tech-savvy commuters and families seeking to escape gas station visits. At a used market price of around $34,500, it sits in a sweet spot where Tesla's historically strong residual values and near-zero fuel costs can genuinely offset the higher purchase price versus comparable ICE SUVs.
Monthly cost breakdown
The 2021 Model Y has held its value exceptionally well compared to most vehicles, retaining roughly 65-70% of its original MSRP after three years, though the used EV market softened in 2023-2024 due to Tesla's aggressive new-car price cuts, which has modestly pressured 2021 residuals downward from their 2022 peak.
Pros
- Electricity costs roughly $55/month at average US rates for 12,000 miles/year versus $150-$200/month for a comparable gas SUV, saving $1,100-$1,700 annually on fuel
- No oil changes, transmission service, or exhaust repairs means maintenance costs are among the lowest in the segment, averaging under $750/year
- Over-the-air software updates continuously add features and fix bugs at no cost, reducing some diagnostic service visits
- Strong brand resale demand keeps depreciation lower than most EVs, limiting monthly depreciation cost to approximately $320 on a $34,500 purchase
Cons
- Insurance premiums average $175/month due to high repair costs from Tesla's proprietary parts and limited certified repair shop network, running above segment average
- Out-of-warranty battery or drive unit repairs can be extremely expensive, with full battery pack replacements costing $10,000-$16,000 if needed outside the 8-year/120,000-mile warranty
- Tesla's price cuts on new models since late 2022 have compressed used values, meaning buyers who purchased at 2022 peak prices absorbed significant paper losses
- Home Level 2 charger installation adds a one-time cost of $500-$1,500 that should be factored into true first-year ownership expenses
Common problems to watch for
- Panel gaps and inconsistent body panel fitment are a frequently reported quality-control issue on 2021 builds, often requiring dealer adjustments
- Heat pump failures or reduced cold-weather range efficiency have been noted in sub-freezing climates, sometimes requiring a warranty or out-of-pocket heat pump service
- Autopilot and Full Self-Driving camera calibration errors can trigger warning lights and require service center recalibration visits
- Trunk and frunk latch mechanisms have been reported to stick or misalign, occasionally needing adjustment or replacement
- 12V battery failures (the auxiliary lead-acid battery) can strand the vehicle and typically run $100-$150 to replace, often occurring around the 3-4 year mark
The verdict
At $34,500 the 2021 Model Y offers genuinely compelling total cost of ownership driven by rock-bottom energy and maintenance bills, and its 5-year all-in cost of roughly $42,720 is competitive with similarly priced gas SUVs once fuel savings are factored in. The main financial risks are insurance costs running higher than average and the tail risk of a post-warranty high-voltage component failure. For buyers who can charge at home and plan to keep the car through the 8-year battery warranty window, it remains one of the smarter used EV buys available in 2024.
Best for: The 2021 Model Y is best for a daily-commuting homeowner who can charge overnight, drives 10,000-15,000 miles per year, and wants to minimize fuel and routine maintenance costs over a 5-year horizon.

Frequently asked questions
Is the 2021 Tesla Model Y still under warranty if I buy it used?
Yes — Tesla's battery and drive unit warranty transfers to subsequent owners and covers 8 years or 120,000 miles from the original in-service date, so a 2021 model still has meaningful powertrain protection remaining through approximately 2029.
How much does it actually cost to charge a 2021 Model Y at home?
At the US average electricity rate of about $0.16/kWh, charging a Model Y Long Range (82 kWh usable) from near-empty costs roughly $13, and at 12,000 miles/year with ~3.5 miles/kWh efficiency you'll spend approximately $550-$650 annually — around $55/month.
What maintenance does a 2021 Tesla Model Y actually need?
Tesla recommends tire rotations every 6,250 miles (~$80-$100 each), cabin air filter replacement every 2 years (~$50-$80), and brake fluid checks every 2 years (~$100); there are no oil changes, spark plugs, or transmission services, keeping annual maintenance well under $500 in most years.
Does the 2021 Model Y qualify for any federal tax credit when buying used?
The Inflation Reduction Act's used EV tax credit of up to $4,000 (30% of sale price, max $4,000) may apply if you meet income limits ($75,000 single / $150,000 married), the vehicle sells for $25,000 or less, and this is the first time the used credit is claimed on that specific VIN — at $34,500, most buyers will not qualify on the price threshold alone.
How does insurance cost compare to a similar gas SUV?
Expect to pay $1,800-$2,400 per year to insure a 2021 Model Y for a driver with a clean record, which is roughly $300-$600 more annually than a comparable Toyota RAV4 or Honda CR-V, primarily due to higher repair labor costs and Tesla's parts supply constraints.
What should I inspect before buying a used 2021 Model Y?
Request a Tesla Service history report to check for any prior collision repairs or battery replacements, verify the battery state-of-health in the Tesla app (aim for 90%+ capacity remaining), and carefully inspect all body panel gaps and glass seals for misalignment that could indicate prior accident repair or factory quality issues.
