Car Sharing Savings Calculator
See how much sharing your commute with colleagues could save you a year, fuel and parking split between everyone in the car, plus what that saving could grow into if you invested it.
Estimate only. These are estimates based on the figures you enter, actual fuel economy, prices and parking charges vary. The 5-year projection assumes a constant growth rate and is illustrative only, not a forecast or guarantee.

How the saving is worked out
Driving alone costs the same fuel and parking every day regardless of who else is in the car, this calculator first works out that solo annual cost using the same fuel maths as the Fuel Cost Calculator, plus your daily parking charge. When you share the car, that same total cost is simply split between everyone travelling, so the saving per person is the solo cost minus their share. Because the total cost doesn't change whether you split it evenly or take it in turns to drive your own cars by rotation, both approaches save you exactly the same amount, the toggle only changes how you'd frame it to the group, not the numbers.
