EV Lease vs Buy Calculator

The EV Lease vs Buy Calculator compares the total cost of leasing an electric vehicle against purchasing one with a loan over the same time period.

Monthly Payment Is the Wrong Starting Point

The first thing most buyers compare is the monthly payment. A 36-month lease on a $44,990 EV might run $598/month, while a 60-month loan on the same vehicle costs $783/month. The lease looks cheaper by $185 every month, and many buyers stop the analysis there. That comparison is misleading because it ignores what happens at the end of each contract.

The lease buyer makes 36 payments totalling roughly $26,500 (including the down payment) and walks away with nothing. The loan buyer makes 36 payments totalling about $33,200 (including down payment and charger installation) but retains a vehicle worth approximately $24,700 at that point, yielding roughly $7,000 in equity. Net cost through 36 months: around $9,700 for the buyer versus $26,500 for the lessee. The "cheaper" monthly payment actually costs $16,800 more over three years once equity is accounted for.

This does not mean buying is always better. It means the right metric is total cost of access — what you pay minus what you keep — not the monthly line item. The decision depends on how long you plan to drive the vehicle, how many miles you cover annually, and how you value flexibility versus equity. You can view total ownership cost side by side for a more complete picture that includes fuel, maintenance, and insurance alongside financing.

A Decision Framework for Lease vs Buy

Rather than treating lease-versus-buy as a single binary question, it helps to work through a branching set of conditions. Each driver's circumstances point toward one option more strongly than the other, and the decision tree below captures the most common scenarios.

How long do you plan to keep this vehicle?

• Under 3 years: Lease is typically cheaper. You avoid the underwater period of a long-term loan (where you owe more than the vehicle is worth) and return the car before any out-of-warranty concerns arise.
• 3 to 5 years: The grey zone. Run the numbers both ways using this calculator. If the vehicle holds its value well (residual above 50%), buying edges ahead. If depreciation is steep, leasing may cost less.
• 5 years or longer: Buying almost always wins. Once the loan is paid off, every subsequent month of driving costs only fuel, insurance, and maintenance — no payment at all. Lessees must either sign a new lease (resetting payments) or buy out the residual.

How many miles do you drive per year?

• Under 10,000 miles: Leases work well because mileage caps (typically 10,000–12,000/year) are not an issue.
• 10,000–15,000 miles: Check the lease mileage allowance carefully. Excess mileage fees of $0.15–$0.30 per mile add up fast. A buyer would negotiate a higher mileage cap (which raises the payment) or lean toward buying.
• Over 15,000 miles: Buying is strongly favoured. High-mileage lease penalties can add $1,500–$4,500 at lease end. A purchased vehicle has no per-mile penalty.

Are you uncertain about committing to an EV?

• Yes, first-time EV driver: A 24-month lease lets you experience electric driving — home charging logistics, range planning, winter performance — without a five-year commitment. If the EV lifestyle does not suit your needs, you return the vehicle and move on.
• No, committed to electric: Buying builds equity and eliminates the recurring cycle of lease-end fees, disposition charges ($350–$500), and the negotiation process every 2–3 years.

These branching conditions do not cover every situation, but they address roughly 80% of cases. Before choosing a financing path, compare running costs between the EV and a gasoline alternative to confirm the EV makes financial sense in the first place.

Lease vs Buy Across Three Holding Periods

The table below models the same $44,990 EV (Tesla Model Y Long Range) under three scenarios: a short lease, a standard lease, and a full purchase. All scenarios assume a $5,000 down payment, a 0.0027 money factor for the lease, a 6.5% loan rate for the purchase, and $1,200 in home charger installation costs for the buyer.

Metric	24-Month Lease	36-Month Lease	60-Month Purchase
Monthly payment	$693	$598	$783
Total payments (inc. down)	$21,632	$26,538	$51,996
Vehicle equity at end	$0	$0	$24,745 (55% residual)
Net cost through lease-end date	$21,632	$26,538	$9,653 (at 36 mo)
Charger installation	Optional	Optional	$1,200 (included above)
Mileage restrictions	10,000–12,000/yr	10,000–12,000/yr	None
Best for	EV-curious, low mileage	Want latest tech cycle	Long-term ownership

The net cost column reveals the scale of the difference. Through 36 months, the buyer's net outlay (total payments plus charger minus equity) is roughly $17,000 less than the lessee's. That gap narrows somewhat if the vehicle depreciates faster than expected, which is why the MSRP residual assumption matters.

The EV-Specific Wrinkle: Battery Technology Cycles

EVs introduce a consideration that traditional lease-versus-buy frameworks do not address: battery technology is evolving rapidly. A vehicle purchased in 2026 may have a 75 kWh battery with 270-mile range. By 2029, the same price point might buy 100 kWh and 350+ miles. For buyers planning to charge at home nightly, the current range may be perfectly adequate. But for those who frequently take long trips or live in cold climates where range drops 20–30%, leasing allows an upgrade to better battery technology every few years without bearing depreciation risk.

Conversely, buying makes more sense when the current vehicle meets your needs for 7–10 years. Battery degradation data from Geotab's 2025 fleet study shows most EV batteries retain 85–90% capacity after eight years, meaning the vehicle remains functional well beyond a typical loan term.

How Incentives Affect the Lease-Buy Equation

State-level incentives can shift the maths. Some states apply incentives only to purchased vehicles, not leased ones. Others allow the leasing company to claim the incentive and pass it through as a reduced capitalised cost. The distinction matters because a $2,000 state incentive applied to a purchase reduces your loan principal directly, while the same incentive on a lease may or may not lower your monthly payment depending on the leasing company's policies. Always review available purchase incentives and ask the dealer how lease incentives are structured before signing.

The interaction between incentives and financing type is one of many factors that feed into your payback timeline. A buyer who receives a $4,000 state rebate reaches break-even against a gasoline alternative years faster than a lessee paying a higher effective price.

Worked Example: Model Y 36-Month Lease vs 60-Month Purchase

A buyer considers a Tesla Model Y Long Range at $44,990 with $5,000 down. The lease terms are 36 months, 55% residual, and a 0.0027 money factor. The purchase alternative is a 60-month loan at 6.5% APR, with a $1,200 charger installation.

Lease calculation: capitalised cost after down payment is $44,990 − $5,000 = $39,990. Residual value: $44,990 × 0.55 = $24,744.50. Depreciation per month: ($39,990 − $24,744.50) ÷ 36 = $423.49. Finance charge per month: ($39,990 + $24,744.50) × 0.0027 = $174.78. Monthly payment: $423.49 + $174.78 = $598.27. Total lease cost: $5,000 + ($598.27 × 36) = $26,537.72, with zero equity at lease end.

Purchase calculation: loan amount is $39,990. Monthly payment at 6.5% over 60 months: approximately $782. Total payments through 36 months: $5,000 + ($782 × 36) + $1,200 = $34,352. Estimated resale at 36 months: $24,744.50. Remaining loan balance at month 36: approximately $17,756. Equity: $24,744.50 − $17,756 = $6,988. Net buy cost through 36 months: $34,352 − $24,744 = $9,608.

The buyer spends about $9,600 net versus the lessee's $26,538 over the same 36 months. The buyer continues making payments through month 60 but owns a vehicle outright at the end.

Worked Example: Equinox EV 24-Month Lease Where the Buyer Ends Up Underwater

A first-time EV driver considers a Chevrolet Equinox EV ($43,295) with $3,000 down. The lease: 24 months, 60% residual, 0.0021 money factor. The purchase: 60-month loan at 6.5%.

Lease: capitalised cost $40,295. Residual: $25,977. Monthly: $596.58 depreciation + $139.17 finance = $735.75. Total: $3,000 + ($735.75 × 24) = $20,658. Purchase: monthly payment approximately $789. Through 24 months: $3,000 + ($789 × 24) + $1,000 charger = $22,936. Resale at 24 months: $43,295 × 0.58 = $25,111. Remaining loan balance at month 24: approximately $27,135. Equity: $25,111 − $27,135 = −$2,024.

The buyer is roughly $2,000 underwater after 24 months. Leasing costs $20,658 while the net buy cost is approximately $24,960. For short holding periods, leasing saves about $4,300. This is especially relevant for those exploring the full cost comparison between EV and gasoline ownership who are not yet certain about their long-term preference.

Money Factor

The money factor is the lease equivalent of a loan interest rate. It represents the financing cost charged by the leasing company, expressed as a small decimal (typically 0.001 to 0.005). To convert a money factor to an approximate APR, multiply by 2,400. A money factor of 0.0027 corresponds to roughly 6.5% APR. The money factor is applied to the sum of the capitalised cost and the residual value to calculate the monthly finance charge. Lower money factors reduce the monthly payment, and like loan rates, they can sometimes be negotiated.

Residual Value

Residual value is the projected worth of a vehicle at the end of a lease term, expressed as a percentage of the original MSRP. The leasing company sets this figure at the start of the lease based on historical depreciation data for similar vehicles. A higher residual (e.g., 60%) means the vehicle is expected to retain more value, which lowers the monthly lease payment because less depreciation is being financed. Residual values for EVs have been volatile as the market matures: some models hold value well while others depreciate faster than their gasoline counterparts, particularly when newer models with longer range or lower prices enter the market.

The lease-versus-buy decision ultimately comes down to how long you plan to keep the vehicle, how many miles you drive, and how much you value ownership equity versus flexibility. For those planning to keep the vehicle beyond the loan term, a full ownership cost projection captures the years of payment-free driving that shift the economics decisively toward buying.
