#### Formulas Used
Maryland Excise Tax Credit (New BEV/FCEV): Credit = min($1,000 + $100 × max(0, kWh − 10), $3,000)
Maryland Excise Tax Credit (New PHEV): Credit = min($500 + $50 × max(0, kWh − 10), $1,000)
Maryland Excise Tax Credit (Used BEV/FCEV): up to $1,500 | Used PHEV: up to $500
Federal EV Tax Credit (New): $7,500 (if eligible) | Used: min($4,000, 30% × sale price)
Maryland EVSE Credit: min(40% × EVSE cost, $700)
Federal EVSE Credit (30C): min(30% × EVSE cost, $1,000)
Annual Fuel Savings: Gas Cost = (Annual Miles ÷ MPG) × Gas Price/gal Electricity Cost = (Annual Miles ÷ EV Efficiency mi/kWh) × Electricity Rate/kWh Annual Savings = Gas Cost − Electricity Cost
5-Year Fuel Savings = Annual Savings × 5
Total 5-Year Savings = Upfront Credits + 5-Year Fuel Savings
#### Assumptions & References
- Maryland Excise Tax Credit is governed by HB 44 / Transportation Article §13-815; annual funding is capped and credits are first-come, first-served. Verify current availability at mva.maryland.gov.
- EV efficiency of 3–4 miles/kWh is typical; check your vehicle's EPA rating at fueleconomy.gov.
- Maryland average electricity rate ≈ $0.13/kWh (EIA, 2024). Average gas price varies; check AAA.
