How the robotaxi owner calculator works
There are two versions of the robotaxi dream, and they are different questions. The first: keep your car as a daily driver, flip it into fleet mode when you are not using it, and let it chip away at its own cost. The second: buy one purely as a side hustle, a machine that works while you sleep. This page runs both, as two modes of one honest model, and it starts with the honesty. As of August 2026 you cannot buy a Cybercab: production started at Giga Texas in early 2026 and roughly 250 vehicles had been spotted on site by late July, but every one is bound for Tesla's own fleet, with consumer sales targeted for 2027. And Tesla's plan to let owners add their cars to the network, described by Musk as a combination of the Uber and Airbnb model, is a stated plan, not an open marketplace: Tesla's own unsupervised Austin fleet was still under 20 cars in July 2026. So this calculator prices the question, not a listing. Every company figure is labeled a target, the measured anchors come from the human rideshare economy that exists today, and the result is an estimate with stated assumptions, not a business plan. Your numbers will vary; the dials are the point.
Enter the car's price, the paid miles you believe it can earn, the fare, and the platform take (the measured 30 percent, the attributed 25 percent target, or your own). The model applies the deadhead share to the costs, prices every driven mile for energy, tires, and depreciation, adds insurance and cleaning, and hands you the verdict in plain words, plus a sensitivity table that runs the same scenario through measured, target, and skeptic assumptions so you can watch the assumptions do the work. If your question is the other one, whether to ride robotaxis instead of owning a car at all, that is our robotaxi cost calculator, next door.
The formula
net revenue = paid miles × fare × (1 - platform take)
fleet costs = driven miles × (energy + maintenance + depreciation per mile) + insurance + cleaning
net fleet income = net revenue - fleet costs
daily driver mode: net fleet income vs the car's full yearly cost
side hustle mode: payback years = price ÷ yearly cash flow, checked against the car's working life
The per-mile costs: energy at 5.22 cents (0.29 kWh per mile at 18 cents per kWh, the same figures as our EV savings calculator; AAA's EV figure of 5.07 cents lands within a fraction of a cent), maintenance and tires at 11.04 cents (AAA 2025), and depreciation at 8.96 cents for marginal miles on a car you keep (AAA's own mileage-band methodology: $448 of extra depreciation per 5,000 extra EV miles). In side hustle mode the depreciation is the sticker itself, spread over an editorial 200,000 mile working life. Revenue is only ever paid miles times fare; deadhead miles touch the cost side alone.
Worked example
A $30,000 vehicle (the class of Tesla's stated Cybercab target; a target, not a price), earning 15,000 paid miles a year at the $2.00 per mile Tesla actually charges in Austin, on the measured 30 percent platform take and 40 percent deadhead.
Daily driver plus fleet mode, with 12,000 personal miles: gross fares 15,000 × $2.00 = $30,000; the platform keeps $9,000, leaving $21,000. Delivering those paid miles takes 25,000 driven miles, which cost 25.22 cents each ($6,305.00), plus $2,000 of insurance increment and $1,300 of cleaning. Net fleet income: $11,395.00 a year. The car itself costs $8,411 of fixed costs plus $1,951.20 of personal driving, $10,362.20 a year, so fleet mode may more than pay for the car: about $1,033 a year ahead, with the purchase earned back in about 2.6 years of fleet work.
Pure side hustle, same car and miles: each driven mile now carries 15 cents of sticker ($30,000 over 200,000 working miles), so 25,000 driven miles cost $7,815.00, plus $3,995 of insurance, $859 of registration, and $1,300 of cleaning. Net profit: $7,031.00 a year, with the cash paying off the car in about 2.8 years against a working life of about 8 years at this pace.
Now the same daily-driver scenario at Tesla's stated 35 cent target fare: net revenue falls to $3,675 against $9,605 of unchanged fleet costs, and fleet mode loses about $5,930 a year. Hold that thought for the section below on what would have to be true.
Deadhead miles: the number that guts naive fleet math
The napkin version of this calculation multiplies paid miles by a fare, subtracts costs on the same miles, and announces a fortune. The road disagrees. A rideshare vehicle spends a large share of its miles with nobody aboard: repositioning after a drop-off, circling toward demand, driving to pickups. The best driver-side study, using data from both sides of the trip, put deadheading at 40.8 percent of all ride-hailing miles on the conservative accounting, 69 empty miles for every 100 passenger miles. And it is not improving: Toronto's city data measured 50 percent in 2025, up from 40 in 2022, and a Seattle-area driver report found the majority of local Uber miles running empty. This page defaults to 40 percent and puts 50 in the skeptic row.
The arithmetic consequence is the whole game: at 40 percent deadhead, delivering 15,000 paid miles means driving 25,000, so every per-mile cost is paying for five miles while three earn. The empty miles earn nothing and wear everything, which is why this model applies deadhead to the costs and never to the revenue. A robotaxi may eventually deadhead less than a human driver (it never drives home), or more (it repositions on an algorithm's hunch, and Waymo's California filings show plenty of empty miles). Nobody knows yet. The dial is yours.
The fleet does not wear out Tesla's car. It wears out yours
Depreciation is the forgotten line in every your-car-earns-money pitch, and it is usually the largest one. Every fleet mile spends the car. For marginal miles on a car you keep, this page uses AAA's own mileage-band methodology: adding 5,000 miles to an EV's year adds about $448 of depreciation, 8.96 cents per mile, and that band was measured going from 15,000 to 20,000 miles a year, so a fleet hammering far past that is an extrapolation in the generous direction. The tax system's opinion sits at the other end: the IRS treats 35 cents of the 2026 business mileage rate as depreciation. The truth for a hard-run fleet car lives somewhere between AAA's gentle band and the IRS convention, which is why side hustle mode does not use the band at all: it spends the whole sticker across a 200,000 mile working life, 15 cents a mile on a $30,000 car, and checks the payback clock against the odometer's. A side hustle that pays the car off in 12 years of a car that is spent in 8 is not a business, and this page will say so.
The insurance nobody can price yet
A personal auto policy excludes commercial use; that part is settled. For human rideshare the market is measured: an endorsement adds roughly $10 to $70 a month to a personal policy, and full commercial coverage runs about $150 to $400 a month. For a privately owned car driving strangers around with nobody in it, there is no product on the shelf at any price, because no insurer has the loss data. Musk has suggested Tesla would handle insurance within the network; that is another stated plan. This page defaults the fleet insurance increment to $2,000 a year, an editorial figure sitting inside the measured commercial band, labels it as such, and leaves it fully editable, with the skeptic row doubling it. When a real rate card appears, it will be one of the most informative numbers in this whole question: an insurance premium is a measured opinion about risk.
The utilization paradox, and what would have to be true
The pitch says your car sits parked 95 percent of the time, so let it work. True, and here is the wrinkle: your car is free exactly when demand is lowest. You drive it at 8 a.m. and 6 p.m.; rideshare demand peaks at 8 a.m., 6 p.m., and weekend nights. The hours your car can join the fleet, midday Tuesday and 3 a.m., are the hours fares are thinnest and deadhead is fattest. A daily driver in fleet mode earns the off-peak scraps unless you start giving up the car at exactly the hours you want it, at which point you are pricing your own convenience back into the math. Pure side hustle mode dodges the conflict but buys the whole cost structure instead.
And one tension deserves plain words, because it sits at the center of the Cybercab story: the cheap-rides future and the your-car-earns-money future come from the same meter. At the $2.00 Austin fare, the worked example clears five figures of fleet income. At Tesla's stated 30 to 40 cent ride target, the same car loses about $5,930 a year, before anyone argues about deadhead or insurance. Cheap rides for everyone and fat yields for owners cannot both come out of one fare. If the math only works at today's human-priced fares, you are betting robotaxis stay expensive; if you believe the target, you are betting against your own side hustle. Turn the fare dial and watch the two futures trade places.
Taxes: fleet income is self-employment income
If a car of yours earns fares, the IRS considers you in business. Net fleet earnings would generally face income tax plus self-employment tax, 15.3 percent up to the Social Security wage base, and quarterly estimated payments would likely be due, since no employer is withholding anything. The deduction side works in your favor: the vehicle's costs offset the income. This page deliberately computes no taxes, because your bracket, your state, and whether you incorporate all change the answer. Our quarterly tax calculator handles the estimates, and our mileage reimbursement calculator covers the per-mile deduction side.
