Fleet Electrification Calculator

Comparing gas and electric fleets on purchase price alone misses most of the real cost difference, which shows up over years of operation rather than at the moment of purchase — so this calculator builds a full total cost of ownership for each option across your chosen comparison period. Each side combines an acquisition cost with annual operating costs multiplied by however many years you're comparing: the ICE side's acquisition is simply vehicle price times fleet size, while the EV side adds charging infrastructure cost and subtracts per-vehicle incentives, since those are real cash flows tied to the EV transition that a straight gas-vehicle purchase never faces. Annual operating costs use a fixed cents-per-mile maintenance estimate for each fuel type — EVs assumed at half the maintenance cost of ICE vehicles, reflecting fewer moving parts and no oil changes — plus actual fuel or electricity cost computed from your entered miles, fuel economy, price per gallon, and electricity rate.

The payback period divides the EV fleet's higher upfront cost by its annual operating savings, showing roughly how many years of lower fuel and maintenance costs it takes to earn back that initial premium; a fleet with high annual mileage recovers that premium faster than a low-mileage fleet, since more miles driven means more fuel savings accumulated per year. CO2 reduction runs the same mileage through each fuel type's emission factor to show the environmental case alongside the financial one. This model uses fixed maintenance-cost-per-mile assumptions and a flat national grid carbon intensity rather than your fleet's actual maintenance records or local grid mix, so treat the output as a planning-grade estimate to refine with your own real cost data.
