How Carpool Savings works

Estimate monthly fuel and parking for the commute, then divide equally by participants. Savings per person are the solo monthly cost minus that equal share.

A worked example

These sample values illustrate the calculation. Use your own numbers in the calculator for your result.

Example inputs

Round-trip distance (miles): 30
Fuel economy (MPG): 30
Gas price ($/gallon): 3.5
Parking per day ($): 10

Carpool monthly cost per person: $97.50

Assumptions and limits

Equal driving rotation and equal cost splitting have the same average cost when each vehicle costs the same to run. All costs are shared equally.
