Money · measured against four gas vehicles
The Ledger.
What the car costs to run, what it is worth, and what it earns. The denominator and the numerator on the same page, because separating them is how people talk themselves into vehicles they cannot afford.
Cost per mile, measured
12.9¢/mi
$442.62 of charging across 3,426.7 miles. Energy only. Insurance and software are separate lines below and are not buried in this figure.
Against the fleet it replaced
| Vehicle | Role | mpg | Per mile |
|---|---|---|---|
| 2024 Model Y LR AWD | Current | n/a | 12.9¢ measured |
| 2015 Chevrolet Express 2500 | Detail van, dealership runs | 13 | 28.0¢ |
| 2016 Toyota Sequoia Platinum 2WD | Stopgap, 15 days | 15 | 24.3¢ |
| 2011 Toyota Sienna Limited | Family hauler | 20 | 18.2¢ |
| Lexus ES300h | Stopgap, 5 days | 44 | 8.3¢ |
Gas figures modeled: each vehicle's measured fuel economy priced at $3.64 a gallon (AAA Tennessee, 2026-08-24). TezLab's own estimate of money saved over this window is $91.60, which is lower because it compares against a generic car of roughly 25 mpg instead of the vehicles actually replaced. Both are honest. They answer different questions.
What this car costs to run
12.9¢ a mile measured: $442.62 of charging across 3,426.7 miles, 1,060.4 kWh at a blended 41.7¢. Electricity is priced from the invoice, so the 7.44% that never reaches the battery is already inside it. Energy only.
A month of running costs
At this car’s pace since September 7, 1,896.3 miles in 29 days, which is 1,962 miles a month:
| Line | A month | A year | A mile |
|---|---|---|---|
| Energy | $253 modeled | $3,042 | 12.9¢ |
| Insurance | $90 measured | $1,080 | 4.6¢ |
| FSD (Supervised) | $99 measured | $1,188 | 5.0¢ |
| Premium Connectivity | $9.99 measured | $120 | 0.5¢ |
| Running costs, at this pace | $452 modeled | $5,429 | 23.1¢ |
Energy is this car’s measured price for a mile at this pace modeled. Insurance and software are billed by the month, so their share of each mile moves with the miles driven. The car drove 94.5% of its miles on FSD (Supervised) measured.
Fuel, against the fleet it replaced

The gas vehicles modeled: each one’s measured fuel economy at $3.64 a gallon (AAA Tennessee, 2026-08-24). Months and years modeled: this car’s own pace, held.
On fuel, the Lexus ES300h is the one vehicle here that costs less per mile than this car.

Not in the number
Tires, registration and maintenance have no invoice in this ledger yet, so none is priced. Neither is what the car gives up in value: Value and warranty shows what lots list it for.
Value and warranty
What lots list them for
CarGurus puts the average listing price of a used 2024 Model Y at $36,283 modeled, up 5.25% over a year and 0.03% over the last 30 days.
This car was listed at $40,999 and bought at $39,900 on August 22, 2026, with 19,256 miles on it measured.
Since then the odometer has moved 3,662.1 miles, to 22,918.1 on October 5, 2026 measured. The car’s record starts with its first logged drive on August 25, 2026, at 19,483.3 miles, so 227.3 miles came before it. From there the drives on record add up to 3,426.4 of the 3,434.8 miles the odometer moved, and 8.4 are not yet placed on a day.
| Model year | Average listing | 30 days | 90 days | A year |
|---|---|---|---|---|
| 2025 | $38,759 | −0.14% | −1.83% | +1.49% |
| 2024 (this car’s year) | $36,283 | +0.03% | −1.37% | +5.25% |
| 2023 | $32,824 | −0.02% | −1.94% | +4.82% |
Average listing price of used Model Ys by model year modeled. Source: CarGurus, used Model Y pricing trends, read September 20, 2026. Each row averages every trim and odometer, so it is where lots sit, not a price for this car.
The steps either side of this car are $2,476 (2025 over 2024) and $3,459 (2024 over 2023) modeled: that is what a year of age lists for, before miles.
The warranty runs on miles
Whichever limit comes first ends the coverage.
| Coverage | Basic vehicle | Battery and drive unit |
|---|---|---|
| The carmaker’s term | 4 years or 50,000 mi | 8 years or 120,000 mi |
| Ends, per the car's app | August 22, 2028 | August 22, 2032 |
| Miles left today | 27,082 measured | 97,082 measured |
| Runs out at this pace | November 2027 modeled | October 2030 modeled |
| Ends early by | 9 months modeled | 22 months modeled |
Terms from The carmaker’s New Vehicle Limited Warranty; end dates from the car's app, August 2026. Miles left is the limit less the odometer measured. The run-out dates hold this car’s pace of 1,962 miles a month modeled.
At this pace the miles, not the years, end both coverages, and the basic warranty is gone in about 14 months. The battery’s floor is 70% of its original capacity. This pack reads 79 of 79 kWh, 0% degradation at 114 cycles measured, and Recurrent scores it 96 of 100 modeled. The warranties belong to the car, so they pass to whoever buys it, for the miles and years that are left.
What the average leaves out
Miles. An average prices a car at any odometer. This one has 22,918 and adds about 1,962 a month.
