How many gas stations are required to keep a nation's fleet on the road?
This calculator estimates the number of retail fueling stations required to support a given population of vehicles. It's a complex spatial and economic problem that can be simplified using Fermi estimation.
By calculating the total annual fuel demand of a region and dividing it by the average throughput of a single station, we can arrive at a surprisingly accurate estimate of the infrastructure required.
According to industry data, there are roughly 145,000 to 150,000 retail fueling stations in the United States.
No, this calculation is strictly for liquid fuel stations. EV charging infrastructure follows a different spatial logic.
Rural stations often have lower throughput but serve a critical geographic need, while urban stations have high throughput but are more densely packed.
This is a standard industry average for a medium-sized station with 8-12 pumps.
