Lease vs Buy a 2026 Kia EV9 for a Family of Four: The 5-Year Cost at 15,000 Miles a Year in Georgia
A reader emailed me last week with the exact question every family cross-shopping their first EV eventually asks: "We need a three-row SUV, we drive about 15,000 miles a year in metro Atlanta, and the dealer keeps pushing a lease on the Kia EV9. Should we lease it, buy it, or just get the Highlander Hybrid and call it a day?"
That's three questions stacked on top of each other, and none of them have a universal answer — they depend on your mileage, your electricity rate, your loan rate, and whether you actually value being insulated from battery degradation risk. So let's build the actual spreadsheet instead of guessing.
Small aside before we get into it: Zürich Airport just put two fully driverless L4 electric shuttles into live service with no human monitor onboard (Electrek, September 2026). If an airport authority trusts an unsupervised electric drivetrain to run continuous duty cycles on live tarmac, the "will the motor and battery hold up" question for a family SUV is largely settled. The real questions for a household buying an EV9 are financial, not mechanical — depreciation, financing structure, and what happens to the battery pack by year five.
The Two Vehicles, Sticker Price First
For 2026, the family-hauler matchup looks like this in Georgia:
| 2026 Kia EV9 Light Long Range RWD | 2026 Toyota Highlander Hybrid LE AWD | |
|---|---|---|
| MSRP | $57,900 | $43,205 |
| Federal tax credit | $0 (repealed) | N/A |
| Georgia state incentive | $0 | $0 |
| Effective price | $57,900 | $43,205 |
| Price gap | $14,695 | — |
Two honest notes here. First, the $7,500 federal clean vehicle credit is gone — we covered the repeal and what still survives it in Federal $7,500 EV Tax Credit Repealed: Does the 2026 Hyundai Ioniq 6 Still Beat the Toyota Camry. Second, Georgia never brought back a state EV rebate after killing its old $5,000 credit in 2015 — our ev_incentives dataset (42 rows, sourced from the DOE's AFDC laws database) shows Georgia as one of the states offering zero purchase-side incentive today. If you're in Georgia, this is a straight math problem with no incentive to lean on.
Fuel Cost: 13.9¢/kWh vs $2.95/Gallon
Using Georgia's residential electricity rate from our eia_electricity_prices dataset (13.9 cents/kWh) and the state's regular gasoline average from eia_gasoline_prices ($2.95/gallon):
EV9 real-world efficiency: doe_fueleconomy rates the EV9 Long Range RWD at roughly 32 kWh/100 miles on the EPA test cycle. A three-row family SUV loaded with kids, cargo, and AC running doesn't test like an empty lab vehicle — applying a 15% real-world derate (consistent with the adjustment we use across heavier EVs) puts actual consumption closer to 37 kWh/100 miles.
- 15,000 miles/year × 0.37 kWh/mile = 5,550 kWh/year
- 5,550 kWh × $0.139/kWh = $771/year to charge at home
Highlander Hybrid real-world mileage: EPA-rated at 36 mpg combined; loaded family driving nets closer to 33 mpg.
- 15,000 miles/year ÷ 33 mpg = 454.5 gallons/year
- 454.5 gallons × $2.95/gallon = $1,341/year
Annual fuel savings for the EV9: $570. That's real, but it's modest — Georgia's gas prices sit below the national average and the EV9 is a heavy vehicle, so this isn't the dramatic fuel-savings story you'd get comparing a compact sedan to an EV in a high-gas-price state like California.
Maintenance: What AAA's Data Actually Shows
Our maintenance_costs dataset, built from AAA's driving-cost studies, puts typical EV maintenance around 5.5 cents/mile versus roughly 7.8 cents/mile for a hybrid SUV (more moving parts — engine, transmission, hybrid battery cooling — even with regenerative braking helping brake life).
- EV9: 15,000 mi × $0.055 = $825/year
- Highlander Hybrid: 15,000 mi × $0.078 = $1,170/year
Combined annual operating savings (fuel + maintenance) for the EV9: $915/year, or $4,575 over five years. This is the kind of layered calculation Celvari runs automatically — you can model this for your specific electricity rate and mileage at Celvari instead of rebuilding the spreadsheet by hand.
Buying the EV9 Outright: The 5-Year Number
Financing both vehicles at a representative 7.2% APR, 60-month auto loan:
| EV9 (Buy) | Highlander Hybrid (Buy) | |
|---|---|---|
| Purchase price | $57,900 | $43,205 |
| 5-yr loan interest | $11,220 | $8,395 |
| Fuel (5 yr) | $3,855 | $6,705 |
| Maintenance (5 yr) | $4,125 | $5,850 |
| Resale value at year 5 | −$22,002 | −$20,738 |
| Net 5-year cost | $55,098 | $43,417 |
That resale gap matters. EVs in our depreciation modeling retain roughly 38% of MSRP after five years versus about 48% for a well-regarded hybrid — battery degradation anxiety among used-car buyers pulls EV resale values down even when the pack itself is fine. The result: buying the EV9 outright costs about $11,681 more than the Highlander Hybrid over five years in Georgia at 15,000 miles a year, with no incentive to close the gap. That's the brutally honest part — for this specific pairing, at this mileage, in this state, the gas-hybrid wins on pure dollars.
This is exactly why we ran a similar matchup with a state rebate in the mix in Kia EV9 vs Toyota Highlander Hybrid: The 5-Year Cost If You Give Up Waiting for the Highlander EV in Colorado — Colorado's $5,000 state rebate changes this verdict. Georgia's zero-incentive environment does not.
The Lease Alternative — And Why It Costs More, Not Less
Dealers push EV9 leases hard because leasing shifts battery-degradation and resale risk onto Kia's captive lender instead of you. Here's what a realistic 36-month lease actually costs:
- Cap cost: $57,900, with $3,000 down
- Residual (50% after 3 years): $28,950
- Depreciation portion: ($54,900 − $28,950) ÷ 36 = $721/month
- Finance charge (money factor ~0.00125): $105/month
- Estimated payment: ~$826/month × 36 = $29,736, plus the $3,000 down = $32,736
But your family drives 15,000 miles a year, and most EV9 leases cap at 10,000. That's 5,000 excess miles/year at roughly $0.20/mile — $3,000 in overage fees over the 3-year term. Add charging ($771/yr × 3 = $2,313) and reduced out-of-pocket maintenance during the warranty period (~$900 for tires and wipers), and the 3-year lease total comes to $38,949, or $12,983/year.
Compare that to the buy scenario's effective annual cost of $11,020/year ($55,098 ÷ 5) — leasing costs more per year here, not less. The premium you pay is for certainty: no resale risk, no degradation risk, and an easy exit at 36 months. If your family's mileage regularly overshoots lease caps, buying is the better financial move even before you factor in the flexibility trade-off.
You can see the same "no federal credit, does a state or leasing structure change the math" question worked through with different vehicles in Which 2026 EVs Qualify for the Full $7,500 Tax Credit — and How to Stack State Rebates if your state has incentives Georgia doesn't.
What Happens to the Battery by Year Five?
The EV9 is too new for five years of real-world fleet data, but Geotab's aggregate EV fleet study (millions of trips across battery chemistries) shows an average degradation rate of about 2.3% per year for modern packs. Applied to the EV9: roughly 88.5% capacity retained at year five, dropping the EPA-rated 304-mile range to a real-world ~269 miles — still comfortably enough for a family's daily driving and most weekend trips.
Kia's battery warranty covers the pack to 70% capacity through 10 years/100,000 miles, so an EV9 sitting at 88.5% at year five is nowhere near a warranty claim or a $15,000+ replacement scenario. This is the kind of degradation modeling — using Geotab and Recurrent field data instead of manufacturer marketing numbers — that should inform your resale expectations, even if it doesn't threaten your ownership costs directly.
Should You Buy Used Instead?
Because EVs depreciate faster in year one and two (the resale-anxiety effect above), a lightly used 2024 or 2025 EV9 might run $38,000–$42,000 — closing most of the gap to the Highlander Hybrid before you even touch fuel and maintenance savings. The catch: the used clean vehicle credit caps out at vehicles priced under $25,000, so a used EV9 won't qualify. A used Hyundai IONIQ 5 or Chevy Bolt in that price band might — we walked through that exact math in Used 2023 Chevy Bolt at $19,000 vs 2026 Toyota Corolla, though that's a smaller car for a smaller family.
If a three-row EV is non-negotiable but you want to avoid the EV9's depreciation hit, buying used and financing the remainder is worth running through your own numbers before signing a new lease.
Run Your Own Numbers
Your electricity rate isn't Georgia's 13.9 cents, your gas price isn't $2.95, and your mileage isn't necessarily 15,000. Every input in this analysis — electricity rates from eia_electricity_prices, gas prices from eia_gasoline_prices, degradation curves from ev_defaults, incentive eligibility from ev_incentives, and maintenance baselines from maintenance_costs — changes the verdict when you swap in your zip code, your driving pattern, and your state's incentive structure. Run the comparison for your own numbers at Celvari before you sign a lease or a loan.
