The question
Eleanor is 68, retired from 34 years of teaching high school English, and drives significantly less than she used to — 6,500 miles a year covering errands, appointments, and Sunday trips out to Framingham to see her grandkids. Her old Corolla is finally showing its age at 190,000 miles and she's ready for one last major vehicle purchase.
Her son-in-law, an engineer, keeps sending her articles about how much money EVs save. She wants to run the numbers herself. The candidates: the 2025 Tesla Model 3 RWD (his recommendation) and the 2025 Toyota Camry Hybrid LE (her instinct). She'll pay cash and expects to keep the car until she stops driving — 5 years is her working assumption, though she notes it could easily be 10.

The 5-year math

|---|---|---|
| MSRP | $28,000 | $43,000 |
| Depreciation (5-yr loss) | $13,216 | $20,296 |
| Fuel or electricity (5-yr) | $2,294 gasoline | $1,872 electricity |
| Insurance (5-yr) | $7,000 | $8,000 |
| Maintenance (5-yr) | $2,900 | $2,300 |
| Massachusetts MOR-EV rebate | — | −$3,500 |
| 5-year true cost to own | $25,410 | $28,968 |
| Difference | Camry Hybrid wins by $3,558 | |
Assumptions: East Coast gasoline at $3.60/gal (EIA PADD 1B average). Eversource with ConnectedSolutions EV credit blended at $0.240/kWh (Massachusetts's rates are among the highest in the US; the ConnectedSolutions program credits back roughly $0.05/kWh for verified off-peak charging). Insurance from Drive Economics's density-and-MSRP model for a Boston ZIP. Maintenance from make and category (Toyota mainstream hybrid; Tesla EV multiplier applied). Depreciation is geometric. Massachusetts MOR-EV rebate for BEVs under $55,000 is $3,500. See methodology.
The verdict
Camry Hybrid wins by $3,558 over 5 years. This is the case study that pushes back on the "EVs always save money" narrative — because at low mileage, high electricity rates, and against a genuinely efficient hybrid, the EV math simply doesn't work.
The fundamental problem: Eleanor's fuel bill on either vehicle is small. She only burns $2,294 in gasoline over 5 years, so the EV can save her at most that much on energy. She saves $422 in electricity vs. gas — a nice number, but not enough to offset $7,080 more in depreciation loss plus $1,000 more in insurance. The MOR-EV rebate ($3,500) helps but doesn't close the gap.
A hybrid at 51 MPG is a genuinely different competitor than a 28-MPG gas vehicle. The Camry Hybrid is not the same math problem as a Camry — it's closer to an EV in operating cost, without the depreciation and insurance premium. For low-mileage buyers in high-electricity-cost regions, hybrids are the quiet default that beats both extremes.
If Eleanor's grandkid decides to live in Vermont at some point and she starts putting 15,000 miles a year on the car, the math flips toward Tesla. If she keeps the car 10 years instead of 5, the Tesla catches up (fuel savings compound and depreciation curves flatten). The question isn't "which is better?" — it's "which is better for how Eleanor actually drives?"
What could change this
- Higher mileage tips toward Tesla. At 12,000 mi/yr the Camry's advantage shrinks to about $1,500. At 18,000 mi/yr Tesla wins by roughly $1,000.
- Longer ownership horizon favors Tesla — 10 years, at 6,500 mi/yr, brings the two roughly even. Depreciation is front-loaded; fuel savings compound.
- Lower Massachusetts electricity rates — Eversource's ConnectedSolutions program requires enrollment and a compatible smart charger. Without it, Eleanor would pay closer to $0.32/kWh and the Camry's win widens to about $4,000.
- Federal EV credit reinstated — the previous $7,500 credit expired Sept 30, 2025 and is excluded from this math. If a $7,500 credit returns, Tesla wins by roughly $4,000.
- Massachusetts MOR-EV changing — the rebate program has been renewed multiple times but is state-budget-dependent. Without it, Camry wins by about $7,000.
- Comparing a non-hybrid Camry instead — a gas Camry at 32 MPG brings a very different comparison. Tesla would win against a regular Camry by about $2,500.
