Fleet Electrification ROI Calculator — Electric Truck TCO vs Diesel

Calculate the ROI and payback period for electric trucks vs diesel. Fuel savings, maintenance reduction, and government incentives vs the purchase premium.

Quick answer: Electric truck fuel savings: $0.07–$0.15/mile vs diesel $0.45–$0.65/mile. Maintenance 30–50% lower. But EV purchase premium is $80K–$150K — payback 2–8 years depending on incentives and usage.

How to Use This Calculator

Enter diesel vs EV purchase prices — get OEM quotes — EV pricing varies by range and payload class.
Enter energy costs — check your depot commercial electricity rate including demand charges.
Enter available incentives — IRA Section 45W ($40K for over 14K GVWR), HVIP (California), and state grants.

Worked Example

Diesel $180K vs EV $290K, 80K mi/yr, 7 MPG, $3.85 diesel, 1.8 mi/kWh, $0.12/kWh, $40K incentives.

Annual fuel saving: ($0.55 − $0.067) × 80K = $38,640
Annual maint saving: $0.08 × 80K = $6,400
Net premium: $290K − $180K − $40K = $70,000
Payback: $70K ÷ $45,040 = 1.6 years

With incentives and high diesel prices, payback can be under 3 years for high-mileage routes. Range limitation and charging infrastructure remain key practical constraints.

Frequently Asked Questions

IRA Section 45W: $40,000 credit per commercial EV over 14K lbs GVWR. California HVIP: up to $150,000/truck. EPA Clean Ports, DERA, and state CMAQ grants vary by state. Multiple incentives can be stacked.

Class 8 EVs (eCascadia, 579EV, VNR Electric): 150–250 miles per charge. Suitable for regional distribution under 200 miles/day with depot charging. Long-haul EV remains limited — hydrogen or diesel for 500+ mile operations.
