#### Formulas Used

CA CVRP Rebate: Fixed rebate by vehicle type and income level (BEV: $2,000–$7,000 | PHEV: $1,000–$6,500 | FCEV: $4,500–$9,500).

Federal Tax Credit: Up to $7,500 per IRS Clean Vehicle Credit (IRC §30D), subject to MSRP caps and taxpayer liability.

Annual Gas Cost = (Annual Miles ÷ Gas MPG) × Gas Price per Gallon

Annual EV Charging Cost = (Annual Miles ÷ EV Efficiency in mi/kWh) × Electricity Rate ($/kWh)

Annual Fuel Savings = Annual Gas Cost − Annual EV Charging Cost

Annual Maintenance Savings = Annual Miles × $0.07/mile (ICE avg $0.10/mi − EV avg $0.03/mi, per AAA)

HOV Lane Value = $500/yr (BEV/FCEV) or $250/yr (PHEV) × Ownership Years

Total Lifetime Savings = Total Upfront Incentives + Total Fuel Savings + Total Maintenance Savings + Total HOV Value

Effective Vehicle Cost = Purchase Price − Total Upfront Incentives

#### Assumptions & References

CA CVRP rebate amounts based on Clean Vehicle Rebate Project (CVRP) income-tiered structure. Standard income CVRP is paused as of 2024; low/moderate income programs remain active via CAReS and Clean Cars 4 All.
Federal Clean Vehicle Credit up to $7,500 per IRS IRC §30D (Inflation Reduction Act 2022). Subject to MSRP limits ($55,000 cars / $80,000 SUVs/trucks) and income caps ($150,000 single / $300,000 joint).
Maintenance savings of $0.07/mile based on AAA Your Driving Costs study (ICE ~$0.10/mi vs EV ~$0.03/mi).
