Someone on Reddit claimed a robo-taxi scenario would produce a 100% ROIC. It sounded too small for me so I tried an example:
Pre-condition: Tesla builds a factory for $5B that can produce 1M robotaxis each costing $30k to manufacture and producing $30k annual profit each. Assume we start tracking after they have produced 0.5M vehicles and are at 1M / year rate for simplicity. That initial 6-12 month ramp would have a loss. So year 1 actually starts with a fleet of 0.5M cars and ends with a fleet of 1.5M cars for an average fleet size of 1M.
Year 1: Fleet = 1M Robotaxis. Profit = (1M cars * $30k / car) = $30B - $30B cost = 0.
Year 2: 2M cars. Profit = (2M cars * $30k / car) = $60B profit - $30B cost. ROIC = $30B / $5B factory cost = 600%.
Year 3: 3M cars. ROIC = 1200%
.
.
Year 10: Fleet 10M cars. ROIC = 5400% (steady state as year 1 cars hit end of life)
At first I thought we’d have to subtract OpEx, but Elon said his profit numbers included all costs. Note that he probably meant for the vehicle itself as well, which if I added back in would raise annual profit to $33k per car.
The idea of a factory that produces widgets with a 10 year life, each generating annual profit enough to pay for the cost of the widget in only 1 year and profits paying off the cost of the factory 6X over in only 18 months is unprecedented I would guess?
Let’s hope Elon’s Autonomy Day numbers are reasonable
