Formulas Used
Federal New EV Credit (§30D):
BEV: $7,500 (if battery ≥ 7 kWh, MSRP within cap, AGI ≤ limit)
PHEV: min($2,500 + $417 × (kWh − 5), $7,500)
Federal Used EV Credit (§25E):
min(30% × Purchase Price, $4,000) — vehicle price must be ≤ $25,000
NJ CHARGE UP Incentive:
min($25 × Battery kWh, $4,000) — new vehicles only, MSRP within cap
NJ Sales Tax Savings:
Vehicle Price × 6.625%
Annual Fuel Savings:
(Annual Miles ÷ MPG × Gas Price) − (Annual Miles ÷ EV Efficiency × Electricity Rate)
Annual Maintenance Savings:
Annual Miles × $0.061/mile (DOE/Consumer Reports average ICE vs EV maintenance differential)
NJ Registration Surcharge Cost:
($250 EV surcharge − $84 avg ICE registration) × Years = $166/year additional cost
Grand Total:
Federal Credit + NJ CHARGE UP + Sales Tax Savings + (Fuel Savings × Years) + (Maintenance Savings × Years) − (Registration Surcharge × Years)
