Compare EV charging access, actual energy costs and full ownership assumptions, verify dated incentives, and keep a practical purchase and follow-up plan.
List ordinary and longest routine trips, parking time, seasonal conditions and reliable backup transport. For each charging location, record access hours, connector compatibility, available power and observed pricing. Identify a fallback if the preferred station is unavailable.
Use annual miles, measured gasoline US MPG and EV electricity billed at the wall per mile. Weight home and public electricity rates by charging share and include extra session fees once. Save a normal case and a case with more public charging.
Ask the property owner and a qualified electrical installer about the parking location, existing circuit, service capacity, suitable equipment, cable routing and permits. Obtain a written installation quote. Check whether available charging can replenish routine use during the actual parking window.
Open Ownership comparison. Assign A and B to specific vehicles, use the same years and miles, then enter purchase, setup, confirmed incentives, interest, annual energy, insurance, maintenance, other fees and resale. Check current program rules before entering any rebate. Rerun lower-resale and higher-repair cases.
Before purchase, verify equipment compatibility, condition, warranty terms and the actual charging arrangement. Keep the final quote and the reason for your decision. After normal use, compare billed charging, mileage and insurance with your assumptions and update the saved comparison.
Keep a dated route and charging-access record with unresolved questions. · Record the equipment and installation quote, permission requirements and charging-window assumptions. · Keep vehicle names, quote dates, inspections and follow-up observations alongside the saved results.
Calculate annual EV electricity and gasoline fuel costs only; copy the totals into the ownership comparison.
Use Ownership comparison for nominal vehicle costs; enter EV and gasoline energy totals from the energy tool. · Replace cost assumptions with observed values while preserving the same comparison period.

IRS guidance excludes clean vehicles acquired after September 30, 2025 from the listed federal clean-vehicle credits. The refueling-property credit is unavailable for property placed in service after June 30, 2026. Earlier acquisitions and installations have additional conditions. Check the linked rules and current local programs; this guide determines no eligibility.
Equipment suitability, electrical capacity, installation cost and permitting depend on the site. A written installation assessment is more useful than a national price or charging-speed assumption.
Nominal cost equals purchase plus setup minus confirmed incentives, plus period interest and operating costs, minus end-of-period resale. Both alternatives use the same holding period. Time value, inflation, loan cash-flow timing and future prices are outside this model.
Billed energy includes charging losses; do not add a second loss allowance to a wall-based consumption figure.
A lower holding-period cost can still require more cash upfront. Check the purchase and loan schedule against your own budget.
