Configure each trim side by side.
Where you'll register, how much you drive, and how long you'll keep it — these shape every group below.
Insurance, property tax, electricity, and gas use editable state averages. Upfront tax is an estimate; rules vary by state and trade-in. Incentives change often; check AFDC ↗, PlugStar ↗, and your DMV or energy office.
Vehicle price is taxed and financeable. Gear is separate, untaxed upfront cash unless you choose to finance it. Trade-in reduces the purchase total and the taxable price.
Temporary federal deduction for interest on a new US-assembled auto loan. R2 qualifies; income limits the benefit.
Money that returns to you: resale when you sell, rebates after purchase.
Each view updates as you change payment type, term, mileage, or ownership horizon.
Save setups to compare true cost side by side. With two or more saved, their cumulative curves overlay below.
The model runs an amortization schedule month by month, adding financing, insurance, electricity, registration + EV fee, property tax on the depreciating value, maintenance, gear, and charger install. It credits the 2025–28 loan-interest deduction when eligible, returns any rebates you enter, and subtracts resale at the end. The result is your true cost. Costs are in today's dollars — set the escalation input above 0 to inflate insurance, maintenance, and electricity year over year.
Depreciation is a two-phase curve: a steeper first year (typical for new EVs, ~18% by month 12), then a gentler slide to your resale-retained % endpoint, so the chart and resale credit agree. The endpoint assumes ~12,000 mi/yr; driving more shifts it down (capped at 5 points, always shown on the chart), driving less shifts it up. The crossover marks when vehicle value rises above the loan balance.
Electricity blends your home rate (state average by default — override with your utility's rate) with the public-charging rate for the miles you don't charge at home. Efficiency is measured from the wall, so home-charging losses (~10%) are already folded in; EPA's 3.77 mi/kWh is a wall figure and the 3.5 default is a conservative real-world one. The gas comparison is fuel only — it doesn't model a gas vehicle's price, insurance, or depreciation.
For purchases, trade-in value reduces the vehicle total and the taxable price: price + destination - trade, vehicle only. State defaults set tax, title, registration, EV fees, and property tax; edit them for your county. The deduction phases out above $100k single / $200k joint MAGI and is gone at $150k / $250k.
