Lease vs buy, EV vs gas, total cost of ownership, and the money side of going electric.
A down payment lowers the monthly payment, cuts total interest, and — because EVs depreciate steeply in year one — is what keeps you from owing more than the car is worth. Around 20% is the common guidance for staying above water through the first two years.
Auto loans amortise: each payment covers the interest accrued since the last one, and the remainder reduces principal. Early payments are mostly interest, later ones mostly principal — which is why a longer term lowers the payment while raising total interest substantially.
Negative equity means owing more than the EV is worth, which steep year-one depreciation plus a small down payment and a long loan produces reliably. Rolling it into the next loan compounds it — the alternatives are paying the difference, keeping the car until it evens out, or a private sale.
Pre-approval from a bank or credit union gives you a rate to negotiate against and separates the financing conversation from the price conversation. Dealer financing can beat it on manufacturer-subsidised rates, but the dealer may add markup to the buy rate — which pre-approval exposes.
Six levers set the payment: vehicle price, down payment, trade-in equity, interest rate, term length, and any rolled-in negative equity. Lengthening the term is the one that lowers the payment while quietly raising total interest — $40,000 at 7% over 60 months costs about $7,500 in interest.
A lease buyout compares one number against another: the residual price written into your contract versus the car’s actual market value at lease end. If the market has fallen below the residual — common with EVs — hand it back; if it is above, the buyout is the better deal.
The fees outside the advertised payment are the acquisition fee, disposition fee at return, documentation fee, and any excess wear or mileage charges. Acquisition and documentation fees are sometimes negotiable; the disposition fee is often waived if you lease again from the same brand.
A lease mileage allowance — typically 10,000, 12,000 or 15,000 a year — directly sets the residual and therefore your payment. Going over costs a per-mile charge at lease end, usually $0.15–$0.30, which is why buying the right tier up front beats paying overage later.
A lease payment is the depreciation fee plus the rent charge. Depreciation is (capitalized cost − residual) ÷ term; the rent charge is (cap cost + residual) × money factor. Multiply the money factor by 2,400 to read it as an APR — 0.00250 is about 6%.
Leasing caps depreciation risk, which is unusually high on EVs, and often captures a federal credit the lessor passes through — at the cost of mileage limits and no equity. Financing costs more monthly but builds equity, and gets cheaper the longer you keep the car past payoff.
Three exits at lease end: return the car, buy it at the contracted residual, or trade it toward something else. A pre-return inspection determines excess wear and mileage charges, so booking it early leaves time to fix tires or cosmetic damage more cheaply than the lessor would charge.
On a used EV the checks that matter are battery state of health, how much of the 8-year/100,000-mile battery warranty transfers, and DC fast charging frequency. Mileage matters far less than on a gas car, because there is no engine wear to accumulate.
A manufacturer CPO program extends the factory warranty and requires a defined inspection; a dealer "certified" program is the dealer’s own promise and carries no factory backing. On an EV the question is specifically whether battery coverage is extended, since that is the expensive component.
Mileage is the wrong headline number on a used EV, because there is no engine to wear out. What matters is battery state of health, how much of the 8-year/100,000-mile battery warranty remains, and how often the car was DC fast charged — heat and fast charging age a pack more than miles do.
Four ways to check battery health before buying: read the state-of-health figure from the car’s own menus or an OBD app, compare indicated range at a known charge level against the original EPA rating, review DC fast charging frequency, and get a dealer battery health report where one exists.
The federally mandated 8-year/100,000-mile battery and powertrain warranty transfers with the vehicle to subsequent owners. Bumper-to-bumper coverage transfers on most brands but is shorter, and some extended or complimentary charging benefits are tied to the original owner and do not transfer.
Without home charging the fuel advantage narrows sharply: public DC fast charging typically costs two to three times residential electricity per kWh, which can push per-mile cost close to a gas car. Workplace or nearby Level 2 charging is what restores the economics.
Monthly EV cost is five line items: the loan or lease payment, electricity for charging, insurance, maintenance, and depreciation. Charging typically runs $40–$55 a month for 1,000 miles at home, and insurance runs higher than a comparable gas car while maintenance runs lower.
Most US states now charge EVs an annual fee, commonly $50–$200, to replace the gasoline tax that funds roads. Some tie it to vehicle weight or to a per-kWh charging tax instead, and the amount varies widely — check your state DMV, since it recurs every year.
Compare six buckets: purchase price, fuel, maintenance, insurance, depreciation and financing. Fuel is where EVs win — roughly $0.043 per mile at $0.15/kWh and 3.5 mi/kWh against $0.117 for a 30 mpg car at $3.50 — and break-even arrives once running savings cover the price gap.
The driving pattern decides it: high annual mileage with home charging favours a full EV, moderate mileage without home charging favours a hybrid, and low mileage often favours keeping a gas car because EV savings are per-mile while the price premium is fixed.
EV savings are per-mile while the price premium is fixed, so low mileage stretches the break-even. On a $4,000 net premium with $1,190 of annual running savings, break-even is 3.4 years at average mileage — halve the miles and it roughly doubles.
EV claims run higher because the pack sits low and gets inspected after almost any underbody impact, bumpers carry ADAS sensors needing recalibration, and fewer shops are manufacturer-certified. Minor-looking damage is routinely not minor once those factors apply.
Because the pack is a large share of an EV’s value, any repair touching it pushes the estimate past the total-loss threshold faster than on a gas car. Suspected pack damage, flood immersion or a thermal event routinely write off a vehicle that looks repairable.
Gap insurance pays the difference between what your insurer settles for and what you still owe. It matters more on an EV because year-one depreciation is steep and total-loss thresholds are reached sooner — a small down payment and a long loan is the profile that needs it most.
The levers that actually move an EV premium are raising the deductible, shopping carriers with real EV experience, bundling, and choosing a model with a lower repair cost profile. The coverage never worth trimming is liability — and on a financed EV, gap.
EV premiums run higher because the battery pack is a large share of vehicle value, ADAS sensors in bumpers need recalibration after minor work, certified repair networks are fewer, parts cost more, and EVs are heavier. Some of it comes back through lower theft rates and strong safety scores.
Electric cars need no oil changes, because they have no internal combustion engine, no engine oil and no oil filter. They still need tyres, brake fluid, cabin air filters, coolant for the battery thermal system, and on some models a reduction-gear fluid change at long intervals — typically a fraction of a gas car’s service cost.
Every EV has a conventional 12-volt battery powering the computers, lights and locks, recharged from the traction pack through a DC-DC converter. It is why a fully charged EV with a dead 12 V battery will not start: no 12 V means the contactors never close.
US federal rules require at least 8 years or 100,000 miles of EV battery coverage, and many states extend that further. Coverage is for defects plus capacity falling below a stated threshold — commonly 70% — and it never covers normal gradual degradation above that line.
Regenerative braking does most of the slowing, so EV brake pads routinely last well past 100,000 miles. The problem becomes underuse: rotors corrode and calipers seize from sitting, so the actual service item is periodic caliper lubrication and brake fluid changes on schedule.
Tires are the one maintenance item where EVs cost more: instant torque and 10–20% more vehicle weight wear them faster, and EV-specific tires with lower rolling resistance and noise-absorbing foam cost more per set. Rotation on schedule and gentle throttle are what extend them.
EVs depreciate most steeply in year one, driven by rapid model improvement, range obsolescence and battery uncertainty in the used market. That makes leasing or buying used comparatively attractive, and it is why gap insurance matters more on an EV than on a gas car.
Selling a used EV well means documenting battery state of health with a screenshot or report, showing charging history, and having the warranty transfer terms ready — because those are the three things every buyer asks. Private sale captures the dealer margin; trade-in may bring a sales-tax credit.
EV-specific value killers are range obsolescence as newer models go further, doubt about battery health without documentation, an outdated charging connector as the market moves to NACS, and heavy DC fast charging history. Documentation of battery state of health is the strongest defence.
