Used Hyundai Kona Electric at $17,500 vs Gas Kona: 5-Year Cost Now That the $4,000 Federal Used EV Credit Is Gone

Here's the comparison: a used 2022 Hyundai Kona Electric at $17,500 against a used 2022 gas Kona at $19,500, driven 12,000 miles a year for five years. Same brand, same body style, nearly the same size. You're comparing powertrains, not an EV sedan to a gas SUV.

The twist is that the federal used clean vehicle credit of up to $4,000 ended for vehicles acquired after September 30, 2025. That credit used to tilt exactly this decision. It required a dealer purchase, a $25,000 price cap, and income limits. Today the question is whether the used-EV math works on its own, and what state and utility money can put back.

My example says a used Kona Electric wins by about $993 over five years with zero incentives. That's a coin flip. Add realistic state and utility help and it becomes a clear win. Drive under roughly 8,500 miles a year, or lean on DC fast charging, and the gas Kona wins.

Every price, rate, and efficiency figure below is an illustrative input I chose, not a quote. Your zip code will change the answer, which is the point of this post.

Why the federal credit ending changes the used-EV math

Kelley Blue Book's guide, Buying a Used Electric Car: 10 Things to Know Before You Buy, opens with the demand side. Used EVs can feel intimidating to first-timers, and rising gasoline costs are pushing more people to consider them. Both are true. The incentive side got thinner while the gas-price side got louder.

The federal credit was worth roughly four times my no-incentive lead ($4,000 against $993). Losing it moved the used-EV decision from "obviously yes" to "show me the spreadsheet."

One practical warning: some dealer pages and older listings still mention the $4,000 credit. If you see it, ask for the date and the eligibility paperwork. Don't negotiate around money that isn't there.

What's left is the state, utility, and pricing layer. It varies enormously by address, and I'll spell out how to stack it below. For a new-car version of the same question, see how big a state EV rebate must be to beat a Corolla without the federal credit.

The worked example: inputs

Input	Used Kona Electric	Used gas Kona
Purchase price	$17,500	$19,500
Value after 5 years	$7,500	$11,500
Real-world efficiency	0.30 kWh/mile at the wall (0.33 on DC fast)	29 mpg
Energy price	14¢/kWh home, 45¢/kWh DC fast	$3.50/gallon
Charging mix	80% home, 20% DC fast	n/a
Maintenance (5 years)	$1,250	$3,000
Insurance (5 years)	$8,500	$7,500
Home Level 2 charger install	$1,200	$0

I deliberately set efficiency a bit worse than the sticker numbers to cover winter and highway driving. Swap in your own utility rate and your local pump price.

Per-mile fuel cost:

EV on home power: 0.30 × $0.14 = 4.2¢ per mile
EV on DC fast: 0.33 × $0.45 = 14.85¢ per mile
EV blended (80/20): 0.8 × 4.2 + 0.2 × 14.85 = 6.33¢ per mile
Gas Kona: $3.50 ÷ 29 = 12.07¢ per mile

The 5-year total at 60,000 miles

Cost line	Used Kona Electric	Used gas Kona
Depreciation	$10,000	$8,000
Energy (60,000 miles)	$3,798	$7,241
Maintenance	$1,250	$3,000
Insurance	$8,500	$7,500
Home charger install	$1,200	$0
Total	$24,748	$25,741

The EV saves $3,443 on fuel and $1,750 on maintenance, which is $5,193. It costs $2,000 more in depreciation, $1,000 more in insurance, and $1,200 for the charger, which is $4,200. The net is $993 in the EV's favor. This excludes financing, sales tax, and registration, which are similar for both cars except for the EV fee I'll cover below.

This is the kind of line-by-line analysis Celvari runs for you with your rates and your mileage, so you don't have to build the spreadsheet yourself.

The break-even that matters: miles per year

Most of the EV's extra costs are fixed per year: depreciation, insurance, and the charger. Its savings are per mile. That gives you a break-even mileage.

The EV's yearly fixed penalty is $490: $400 depreciation + $200 insurance + $240 charger, minus $350 in maintenance savings. Its per-mile fuel advantage is 12.07¢ − 6.33¢ = 5.74¢.

Break-even = $490 ÷ $0.0574 ≈ 8,540 miles per year.

Charging habit	Fuel advantage per mile	Break-even miles per year	5-year lead at 12,000 mi/yr
Home only	7.87¢	about 6,230	$2,271
80% home / 20% DC fast	5.74¢	about 8,540	$993
70% home / 30% DC fast	4.67¢	about 10,480	$354

Going from 20% to 30% DC fast charging cuts the lead by almost two-thirds. That's the most sensitive input in the model, so it gets its own section.

Charging price is the swing factor

At 45¢/kWh on DC fast, the EV costs 14.85¢ per mile. That's more than the gas Kona's 12.07¢. The crossover price is $0.1207 ÷ 0.33 = about 36.6¢/kWh. Above that, a DC fast charge is a worse fuel deal than gas at $3.50 in this example.

So the useful question isn't "is an EV cheaper to fuel?" It's "what share of my energy comes from home, and what do I pay for the rest?" If you can't charge at home at all, read the apartment-dweller version of this math before you shop.

Electrek's report, IONNA tops 180 charging sites, with discounts for these EV drivers, says IONNA now has more than 180 sites open across the US. Drivers of four of its founding automakers' brands can now get discounts when they plug in. Two things follow for a used-car buyer:

Check whether your car's brand is one of the four. I can't tell from the coverage which brands qualify or how large the discounts are. Confirm it in the charging app before you assume the posted price is yours.
Run what a discount would be worth. Suppose a 20% discount dropped 45¢ to 36¢. DC fast would cost 0.33 × $0.36 = 11.88¢ per mile, barely under gas. The blended rate would fall to 5.74¢, adding about $356 to the five-year lead. That helps, but a discount doesn't turn DC fast into a bargain.

Also look at which stations are near your routes. Corridor stations funded through the federal NEVI program are built to reduce road-trip risk. Funding and state rollout have been uneven, so check your state DOT's list of stations that are actually open, not the announced ones.

What if gas keeps climbing?

KBB's framing is that rising gas prices are what bring people to used EVs. Here's the same 80/20 mix at different pump prices, at 12,000 miles per year:

Gas price	Gas Kona cost per mile	5-year EV lead
$3.00	10.34¢	about −$41 (gas ahead)
$3.50	12.07¢	$993
$4.00	13.79¢	$2,028
$4.50	15.52¢	$3,062

Each 50¢ move in gas adds about $1,035 to the EV's lead. But a $3.00 pump price erases it entirely. Don't buy an EV on a gas-price forecast. Buy it if it wins at the gas price you're paying now and treats any rise as a bonus.

For more on gas-price scenarios, see per-mile fuel cost at $3.00, $3.50, and $4.00 a gallon.

Rebuilding the lead: what incentives are left and how to stack them

With the federal credit gone, used-EV help comes from three places. Here's an example stack, not a promise:

Step	Adjustment	Running 5-year lead
Base case, no incentives	n/a	$993
State annual EV registration fee, $150/yr (example)	−$750	$243
Utility Level 2 charger rebate (example)	+$500	$743
State used-EV rebate or tax credit (example)	+$2,000	$2,743
Overnight time-of-use rate of 10¢ instead of 14¢ for home charging	+$576	$3,319

The $576 comes from home charging at 3.0¢ per mile instead of 4.2¢, which drops the blend to 5.37¢ and saves 0.96¢ across 60,000 miles. Note that the penalty side is real too. Many states now add an annual EV fee, and a time-of-use plan changes what the rest of your household pays at 6 p.m.

Eligibility traps to check before you count any of this money:

Dealer vs private sale. Many programs only cover purchases from licensed dealers.
Price and age caps. Programs often cap the vehicle price or model-year age. A $17,500 car passes, but a $26,000 used EV might not.
Income limits. Some state and utility programs are income-tested. Check household limits, not just yours.
Point-of-sale vs claim-later. A rebate at the dealer is cash now. A tax credit only helps if you owe enough tax to use it. Check whether it's refundable.
Pre-approval. Some rebates require an application before you buy. Buying first can void them.
Funding status. Programs run out of money mid-year. Confirm that funds remain.
Charger rebates. Don't assume the old federal home-charger credit is still available. Check your utility's and state's current programs.

Stacking rules and dollar amounts differ by state and utility, so this part has to be run against your address. Celvari lets you model these inputs for your specific situation and see which ones actually change your break-even.

The battery question you can't skip on a used car

Nobody has "a" battery-degradation number. The data vary by model, climate, and charging habits. As a planning assumption, use roughly 2% capacity loss per year. That's in the range large fleet studies like Geotab's have reported, but check their latest numbers.

For a used Kona, degradation matters in two ways:

Range shrinks. A smaller usable pack means more charging stops. That pushes you from the 20% DC fast scenario toward the 30% one, which cut the lead from $993 to $354.
Warranty coverage may not follow the car. Transfer terms vary by brand and sometimes shrink for a second owner. Get the remaining coverage in writing.

Ask for a battery state-of-health report before you sign. For the warranty side of the same model, read Kona Electric battery degradation at 100,000 miles. Dealers who can't produce a health report are telling you something.

What BYD's $10,000 EV and e-bikes tell you

Electrek's BYD's cheapest EV is getting bigger and fancier reports that BYD is overhauling its roughly $10,000 Seagull. The second generation gets a larger, more upscale design with a few luxury features. It shows where global EV pricing is heading. I wouldn't plan your purchase around putting one in a US driveway, though.

If you're tempted to wait, use your lead as the cost of waiting. In my no-incentive case, that's about $199 a year ($993 ÷ 5). In the full-stack case, it's about $664 a year ($3,319 ÷ 5).

There's also a low-mileage answer. If you drive 4,000 miles a year, the break-even says the gas Kona wins. For short trips, cheaper options exist. Electrek's Green Deals roundup featured a Monarc e-bike bundle with an $838 free extra battery, smart helmet, and stem bag. Its piece on teenagers and e-bikes is a reminder that two wheels are real transportation for many households.

What to do before you sign

Count your real miles. Under about 8,500 a year, this example favors gas. Over about 10,000 with home charging, it favors the EV.
Get your actual electricity rate, including any overnight plan, and your local pump price.
Decide your DC fast share honestly. If you can't charge at home, rerun everything.
Check your brand's IONNA discount and the stations along your routes.
List every incentive with its eligibility rules before you count it.
Get the battery report and the warranty terms in writing.

If you want to see how this shifts with a used Bolt instead, see the used 2023 Chevy Bolt vs Corolla breakdown. If you want it run with your miles, your zip code's rates, and your state's incentives, Celvari does that comparison in a few minutes. I'd rather you find out your break-even is 11,000 miles before you buy than after.
