EV Total Cost of Ownership Calculator

The EV Total Cost of Ownership Calculator computes every cost of owning an electric vehicle versus a gasoline car across your chosen ownership period.

From Year 1 to Year 10: How Ownership Costs Actually Accumulate

Sticker price is a snapshot. Ownership cost is a film. A vehicle that costs $14,000 more on day one can cost less overall by year five, because every month of driving adds fuel, maintenance, insurance, and financing charges that compound in different directions for electric and gasoline powertrains. The TCO framework captures all of these streams and lets you compare them on equal terms.

The trajectory below traces how costs build for two real vehicles — a Tesla Model Y Long Range ($44,990) and a Toyota RAV4 ($30,900) — using California pricing. The goal is not to declare a winner but to show where each cost category bites and when the cumulative lines cross. If you want to start with a quick fuel cost comparison before examining the full picture, the fuel-only calculator isolates that single variable.

The Six Cost Categories, in the Order You Pay Them

Purchase Price and Incentives (Day 1)

The EV carries a higher MSRP in most segments. A Model Y starts at $44,990; a comparably sized RAV4 at $30,900. That $14,090 gap is the single largest line item favouring the gasoline vehicle, and it dominates the comparison in year one. State and federal incentives, where available, reduce this gap. Some states offer $2,000–$7,500 in combined credits, which can narrow the effective purchase gap to under $10,000. To factor in available state incentives, check current programme eligibility for your specific vehicle and filing status.

The purchase price also determines the loan principal, which feeds directly into the next cost category.

Financing Interest (Months 1–60)

A higher loan amount means more interest paid. Financing $39,990 (Model Y minus $5,000 down) at 6.5% APR for 60 months generates $7,006 in total interest. The same terms applied to $25,900 (RAV4 minus $5,000 down) yield $4,552 in interest. The EV buyer pays $2,454 more in financing charges over the loan term.

This is a real cost that many simple comparisons omit. Longer loan terms (72 or 84 months) reduce monthly payments but increase total interest substantially — sometimes adding $2,000–$4,000 to the financing bill. If you are weighing a loan against a lease, the leasing versus financing comparison breaks down when each option makes more financial sense.

Fuel Costs (Every Month, Indefinitely)

Fuel is where the EV begins clawing back the purchase premium. At California's off-peak residential rate of $0.16 per kWh, a Model Y rated at 270 Wh/mi costs $720 per year to fuel when driving 15,000 miles. The RAV4 at 30 MPG and $5.89 per gallon costs $2,945 per year. That $2,225 annual fuel savings is the single largest recurring advantage for the EV.

Over five years, cumulative fuel costs reach $3,600 for the EV and $14,725 for the gasoline vehicle — a difference of $11,125. This alone recovers nearly 80% of the $14,090 purchase price gap. To estimate your annual charging expenses with your actual electricity rate and vehicle efficiency, the charging cost calculator provides a session-level breakdown.

Maintenance (Year 1 Onward, Accelerating for ICE)

EV maintenance costs start low and stay relatively flat: tyre rotations, cabin air filters, brake fluid, and windscreen wiper replacements. Consumer Reports 2024 data places the average at $600 per year. Gasoline vehicles average $1,200 per year, with costs increasing after year three as wear items like brake pads, engine mounts, and transmission servicing come due.

The $600 annual maintenance differential totals $3,000 over five years and $6,000 over ten. Critically, gasoline maintenance costs tend to accelerate in later years while EV costs remain stable, widening the gap as the ownership period extends.

Insurance (Every Year, Higher for EVs)

EV insurance premiums run 15–25% higher than comparable gasoline vehicles, according to industry data from Insure.com and NerdWallet. The Model Y averages roughly $1,800 per year versus $1,500 for the RAV4 — a $300 annual penalty for the EV. Over five years, the EV owner pays $1,500 more in insurance.

This cost partially offsets the maintenance savings. Higher EV premiums reflect costlier repairs (aluminium body panels, battery-integrated structures) and higher parts prices, not higher accident rates. As more body shops develop EV repair expertise and parts supply chains mature, this gap is expected to narrow — but for current buyers, it is a real ongoing cost that should not be ignored.

Depreciation (Compounding Annually)

Both EVs and gasoline vehicles lose roughly 15% of their current value each year on average. Applied to the Model Y's $44,990 MSRP, five years of 15% compound depreciation leaves a residual value of approximately $19,962 — a loss of $25,028. The RAV4 starting at $30,900 depreciates to $13,706, losing $17,194. The EV loses $7,834 more in absolute depreciation because its starting price is higher.

Depreciation is the largest single cost for both vehicles — often exceeding fuel, maintenance, and insurance combined. It is also the most variable, since actual resale values depend on demand, battery health perception, and model-specific factors. Some EVs hold value better than the 15% average (Tesla has historically performed well here), while others depreciate faster (first-generation models with limited range).

Year-by-Year Cost Crossover

The table below tracks cumulative TCO for the Model Y versus RAV4 scenario described above, showing how the EV's lower running costs gradually close the purchase price gap.

End of Year	EV Cumulative TCO	Gas Cumulative TCO	EV Premium / (Savings)
1	$48,111	$36,551	$11,560
2	$51,231	$42,196	$9,035
3	$54,351	$47,841	$6,510
4	$57,471	$53,486	$3,985
5	$47,634	$49,971	($2,337)

Years 1 through 4 show cumulative spending without accounting for resale. The EV remains more expensive in gross outflows throughout this period, though the gap narrows by roughly $2,500 per year. At the end of year 5, when resale values are subtracted, the EV's TCO drops below the gasoline vehicle's by approximately $2,337. This crossover point is specific to the California high-gas-price scenario; in states with cheaper gasoline or more expensive electricity, the crossover may arrive later — or not at all within five years. You can find your ownership break-even point by entering your specific costs.

What Extends or Shortens the Payback Period

Several factors shift the crossover point earlier or later. Understanding which variables have the greatest impact helps you model scenarios that match your actual situation rather than national averages.

• Gasoline price has the largest impact. Each $1.00 increase in gas price adds roughly $500 per year to the gasoline vehicle's TCO at 15,000 miles and 30 MPG. California drivers ($5.89/gal) see the EV pay for itself years earlier than drivers in states where gasoline sits near $3.00.
• Annual mileage amplifies all per-mile savings. A driver covering 20,000 miles per year accumulates fuel and maintenance savings 67% faster than a 12,000-mile driver.
• Electricity rate affects the EV side. Drivers on TOU off-peak plans ($0.08–$0.12/kWh) accumulate savings faster; those relying on public DC fast charging ($0.40+/kWh) may not reach a crossover within five years.
• Purchase price gap sets the starting deficit. A $3,000 gap (Bolt EUV vs Civic) closes in two years; a $25,000 gap (F-150 Lightning vs F-150) may take seven or more.
• Incentives reduce day-one cost and accelerate crossover proportionally. A $7,500 credit applied to the Model Y scenario would move the crossover from year 5 to approximately year 3.

Adjusting these five variables in the calculator above covers the vast majority of real-world ownership scenarios. For the per-mile perspective on these same costs, you can understand your per-mile running cost broken down by category.

Costs This Calculator Does Not Include

TCO calculators model the largest, most predictable cost streams. Several less predictable costs fall outside the standard model but are worth noting for completeness.

Registration fees vary by state and sometimes penalise EVs with higher annual fees to compensate for lost fuel tax revenue. In some states, this adds $100–$200 per year. Home charger installation ($500–$2,000 for a Level 2 setup) is a one-time cost that most TCO tools omit because it varies enormously based on existing electrical panel capacity and local labour rates. Battery replacement is a valid long-term concern but is rarely needed within the first 8–10 years due to manufacturer warranties covering 100,000 miles of use.

None of these excluded costs typically change the overall direction of the comparison — they shift the crossover point by months, not years — but they are worth budgeting for separately.

Worked Example: Five-Year TCO — Model Y Versus RAV4 in California

This worked example traces every dollar for the California scenario used throughout this page. Both vehicles are financed with $5,000 down at 6.5% APR over 60 months. The driver covers 15,000 miles per year, charges at an off-peak rate of $0.16/kWh, and pays $5.89 per gallon for gasoline.

The Model Y's financed amount is $39,990, producing monthly payments of $783.26 and total interest of $7,006 over the loan. Five-year fuel cost: $720 per year × 5 = $3,600. Maintenance: $600 × 5 = $3,000. Insurance: $1,800 × 5 = $9,000. Depreciation leaves a residual of $19,962. Total EV TCO: $44,990 + $7,006 + $3,600 + $3,000 + $9,000 − $19,962 = $47,634.

The RAV4's financed amount is $25,900, producing monthly payments of $507.53 and total interest of $4,552. Five-year fuel cost: $2,945 × 5 = $14,725. Maintenance: $1,200 × 5 = $6,000. Insurance: $1,500 × 5 = $7,500. Residual value: $13,706. Total gas TCO: $30,900 + $4,552 + $14,725 + $6,000 + $7,500 − $13,706 = $49,971.

The Model Y costs $2,337 less to own over five years despite its $14,090 higher purchase price. The fuel savings ($11,125) and maintenance savings ($3,000) more than compensate for the higher financing cost ($2,454), higher insurance ($1,500), and higher absolute depreciation ($7,834). The EV's advantage here is driven heavily by California's gasoline prices; at the US national average of $4.06 per gallon, the gap narrows considerably.

Worked Example: Budget TCO — Bolt EUV Versus Civic in Texas

A tighter comparison: the Chevrolet Bolt EUV at $27,800 versus the Honda Civic at $25,000, financed with $3,000 down at 6.5% APR over 60 months. Annual driving is 12,000 miles with Texas residential electricity at $0.142/kWh and gasoline at $3.65 per gallon.

The Bolt EUV's financed amount ($24,800) generates $4,361 in interest over the loan term. Five-year fuel: $530 × 5 = $2,651. Maintenance: $500 × 5 = $2,500. Insurance: $1,600 × 5 = $8,000. Residual value at 15% annual depreciation: $12,327. EV TCO: $27,800 + $4,361 + $2,651 + $2,500 + $8,000 − $12,327 = $32,984.

The Civic's financed amount ($22,000) produces $3,869 in interest. Fuel: $1,217 × 5 = $6,083. Maintenance: $1,100 × 5 = $5,500. Insurance: $1,400 × 5 = $7,000. Residual: $11,087. Gas TCO: $25,000 + $3,869 + $6,083 + $5,500 + $7,000 − $11,087 = $36,365.

The Bolt EUV saves approximately $3,381 over five years. The smaller purchase price gap ($2,800) means the Bolt reaches cost parity faster — roughly by year two. Even in a low-gasoline-price state, the combination of cheaper electricity and lower maintenance creates a clear running-cost advantage that accumulates steadily over time.

Glossary

Depreciation

Depreciation is the decline in a vehicle's market value over time. It is the difference between what you paid and what you could sell the vehicle for at any given point. For both EVs and gasoline vehicles, depreciation is typically the single largest ownership cost — often exceeding the total spent on fuel over the same period. This calculator models depreciation using a compound annual rate (default 15%), meaning the vehicle loses 15% of its current value each year: a $45,000 vehicle is worth $38,250 after year one, $32,513 after year two, and so on. Actual depreciation varies by brand, model, demand, and condition.

Amortisation

In the context of vehicle financing, amortisation refers to the gradual repayment of a loan through regular monthly instalments that cover both principal and interest. Early payments in an amortised loan go disproportionately toward interest, while later payments apply more to principal. The standard amortisation formula — M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] — calculates the fixed monthly payment based on principal (P), monthly interest rate (r), and total number of payments (n). This calculator uses this formula to determine financing costs for both vehicles, ensuring the interest comparison is accurate and consistent.
