Here's How Much The Hyperloop Will Cost

A ticket on the Hyperloop will cost just $20, according to Elon Musk's math.

The Tesla CEO tallies the total cost of the most advanced Hyperloop project at $7.5 billion.

That's for the passenger plus pedestrian version of the project.

A passenger-only edition costs $6 billion.

Musk says it will take 20 years to build.

So here's how he gets to $20

...transporting 7.4 million people each way and amortizing the cost of $6 billion over 20 years gives a ticket price of $20 for a one-way trip for the passenger version of Hyperloop.

Here's the rundown, via his explanatory .pdf.

To put this in perspective, California's high-speed rail project — which is set to enter its second year of delays — has a price tag of $68 billion.

Ambitious.
