This is a scenario, not a quote or earnings forecast. Vehicle access, local permission, demand and platform terms must be verified. With no launch or no customers, revenue can be zero while costs continue.
How this calculator works & sources
Our own model, inspired by the questions in Ledge Andary’s Robotaxi video (inputs at 1:31–8:15). It does not reproduce or audit his spreadsheet. All default costs are editable examples, not Tesla prices or confirmed owner terms. Check Tesla’s official Robotaxi information alongside local requirements.
Revenue: completed trips × base fare + paid miles × mileage fare. Active days = scheduled days × (1 − extra downtime). In trip mode, completed trips depend on driving speed, extra empty miles, loading time and demand.
Empty miles: “30% extra” means 30 empty miles for every 100 paid miles (130 total). That is 23.1% of total miles. The video uses this arithmetic while also describing 30% of driving; those are different definitions.
Cash: revenue − platform fee − energy/maintenance − vehicle bills − shared bills − loan payments − cash set aside. Cash set aside is a transfer to reserves, not an accounting expense. Cash flow is not accounting profit; depreciation, income tax, resale proceeds and gains in vehicle value are excluded.
Financing: standard fixed-rate amortizing loan on all-in price minus down payment. A down payment does not remove the remaining debt. Starting cash includes down payments (or full cash price), fleet setup and an opening cash buffer. The buffer is tied-up cash, not a loss. Recurring reserves must not duplicate costs already budgeted.
Projection: a fixed fleet with unchanged demand and operating costs. Loan payments stop after the entered term. No automatic reinvestment, new borrowing, fleet growth, depreciation deduction or resale value is assumed. Payback is the first whole month, within 60 months, when modeled cash covers the initial outlay, including the buffer.
Use scheduled days for your normal days off, charging and service schedule. Extra downtime reduces those days further; avoid counting the same downtime twice. “Time with ride demand” is the share of scheduled hours spent completing trip cycles; it is not the share of miles carrying passengers. Insurance, cleaning, software, permits and reserves are per vehicle. Shared rent/staff/admin and one-time setup are fleet totals. Revisit shared capacity and costs when adding vehicles.
