Is an EV Worth It at Low km? What 5,000 and 10,000 km a Year Actually Costs

Is an EV worth it at low km? Usually yes if it costs about the same to buy and insure as the petrol car or hybrid you would otherwise choose. Usually no if you are paying thousands extra to save on fuel. At 5,000 km a year, a small EV saves about $449 on energy against a small petrol car, and only $189 against a hybrid, at October 2026 prices.

Most of the EV savings you see quoted assume far more driving. The average Australian passenger vehicle covered 11,100 km a year in the ABS’s final Survey of Motor Vehicle Use (year to June 2020). Drop to 5,000 km and the fuel saving halves, while insurance, depreciation and annual servicing barely move.

That doesn’t kill the case for a low-km EV. It just changes what decides it. Home solar, a quiet life at home during the day and a sharp purchase price matter more than the fuel bill. Here is the maths, plus the situations where keeping your current car is the smartest move. For models and specs, start with our electric vehicle guide.

Is an EV Worth It at Low km? Start With Energy Costs

On energy alone, yes, but the dollars are small. We compared a small EV using 16 kWh/100 km with an MG3 Vibe at 6.0 L/100 km and a Toyota Yaris Cross Hybrid at 3.8 L/100 km.

Petrol is the swing factor. The ACCC’s five-city average was 236.2 c/L on 21 October 2026, which was 65.3 c/L above the level on 20 February, before the Middle East conflict escalated. So we ran both prices. Grid power uses NRMA’s blended 32.5 c/kWh from its August 2026 cost study. Solar uses 5 c/kWh, the feed-in credit you give up, which sits within IPART’s 2026-27 NSW benchmark of 3.4 to 6.5 c/kWh.

Annual energy cost	5,000 km	10,000 km
Small petrol at $2.36/L	$709	$1,417
Small hybrid at $2.36/L	$449	$898
Small petrol at $1.71/L	$513	$1,025
Small hybrid at $1.71/L	$325	$649
EV on grid power	$260	$520
EV mostly on solar	$40	$80

These use claimed consumption and leave out charging losses, so expect a slightly higher EV figure in practice. You can run your own numbers in our EV charging cost calculator.

Against a petrol car at today’s price, a grid-charged EV saves $449 a year at 5,000 km and $897 at 10,000 km. Against the hybrid, that falls to $189 and $378. If petrol returned to $1.71/L, the hybrid gap would shrink to just $65 and $129.

Solar changes the picture. An EV charged mostly from your own panels saves $409 a year against the hybrid at 5,000 km and $818 at 10,000 km, even at today’s fuel price. That is why retirees with panels keep coming out ahead in these calculations.

One future cost could bite NSW drivers. The state’s road user charge is legislated to start on 1 July 2027 at 3.095 c/km, or $155 a year at 5,000 km and $310 at 10,000 km. A NSW parliamentary committee reported in September 2026 that the charge would likely be struck down as written, so it is far from certain. If it did proceed, most of that small hybrid saving would disappear.

The Costs That Don’t Shrink When You Drive Less

Insurance, depreciation and annual servicing all run on the calendar. At low km, they matter more than fuel.

NRMA’s August 2026 study of small cars over five years and 55,500 km gives the clearest Australian comparison we found:

Five-year small-car average (NRMA, 2026)	EV	Hybrid	Petrol
Energy or fuel	$2,781	$4,215	$6,143
Servicing	$1,335	$1,817	$2,187
Insurance	$9,552	Not published	$7,447
Share of price lost to depreciation	54.6%	53.4%	53.6%

Insurance deserves your attention first. The average small EV cost $2,105 more to insure over five years, or about $421 a year. At 5,000 km, that nearly cancels the $449 energy saving against petrol. The gap varies widely by model. NRMA’s five-year figures put the BYD Atto 1 at $7,585, the MG3 at $6,891, the MG4 at $9,647 and the GAC Aion UT at $13,748. Get a real quote before you fall for a car.

Servicing still happens yearly on most of these cars, whatever the odometer says. The BYD Atto 1 has a 12 month or 20,000 km schedule (Drive, 2026). The Yaris Cross is 12 months or 15,000 km at a capped $255 a visit (NRMA, June 2026). A low-km driver hits the time limit first in both, so don’t expect the EV’s longer distance interval to help. The small-car average still favours EVs by about $96 a year against hybrids and $170 against petrol.

Depreciation dwarfs everything. Average small-car depreciation in that study was $16,295 for an EV and $15,073 for a petrol car over five years. That is more than $3,000 a year, either way. You lose it whether you drive 5,000 km or 15,000 km, although a lower odometer should help resale a little.

Our EV total cost of ownership guide covers the full picture at higher distances.

The Purchase Price Usually Decides It

For a low-km buyer, the price gap matters far more than the energy gap. A premium of $5,000 over a hybrid takes about 13 years to recover at 10,000 km on grid power. On solar, it takes about six. Against a petrol car at 5,000 km on grid power, the same $5,000 takes around 11 years.

Prices have moved in the EV’s favour. As of October 2026, BYD’s Atto 1 Essential is on offer at $19,990 drive-away until 15 December 2026, unless extended (CarExpert, September 2026). That compares with about $26,993 drive-away in Sydney before the offer. MG’s matching $19,990 drive-away offer on the MG3 Vibe ended on 30 September.

Car	Price as of October 2026	Type
BYD Atto 1 Essential	$19,990 drive-away (offer ends 15 Dec 2026)	EV
Geely EX2	From $26,490 before on-roads	EV
MG4 Urban	$29,990 drive-away	EV
GAC Aion UT	$31,990 drive-away	EV
Toyota Yaris Cross Hybrid	From $31,790 before on-roads	Hybrid

NRMA’s study had the Atto 1 Essential costing just $665 more than the MG3 Vibe over five years, at $30,616 against $29,951. It predates BYD’s September offer, so treat that gap as a snapshot. The takeaway holds: at equal money, the EV’s running costs win. At thousands more, they rarely catch up during a low-km ownership period.

The range on the cheapest cars is limited, so check it matches your longest regular trip. Most people driving 5,000 km a year don’t need a big battery. They may still want one for a long trip to see family. Our EV vs hybrid guide helps if that trip is the sticking point.

Solar, Free Midday Power and a Normal Power Point

A low-km EV suits people who are home during the day, because it needs so little energy. At 10,000 km a year, you need about 4.4 kWh a day. A 10A power point delivers about 2.3 kW, so that takes roughly two hours. At 5,000 km, it takes about an hour.

So most low-km drivers can skip the wall charger, as long as an electrician confirms the circuit is suitable for regular charging. Our granny charger vs wall charger guide explains when a wallbox earns its keep.

Retirees have an edge that commuters lack: the car is in the driveway at midday. That lets you soak up cheap solar, or use a free-power plan. The federal Solar Sharer Offer gives households with smart meters free electricity for three hours a day in NSW, South East Queensland and South Australia, up to 24 kWh. Victoria’s Midday Power Saver runs from 11 am to 2 pm.

On a 10A socket, three free hours adds about 6.9 kWh, or around 43 km. Roughly two sessions a week covers 5,000 km a year. Four or five cover 10,000 km.

Read the fine print first. These plans can carry high evening rates, and they can lift bills for households that use a lot of peak power. Our Solar Sharer guide runs through who wins and loses.

If you already have a home battery, keep it working for the house in the evening rather than emptying it into the car overnight. A sunny-day top-up usually makes better use of both.

Does Sitting Around Hurt an EV Battery?

Light use appears to be easy on the battery. Geotab’s April 2026 analysis of more than 22,700 EVs found average capacity loss of 2.3% a year. Low-use vehicles lost about 1.5% a year, projecting to 88% health after eight years. That is overseas fleet data, so treat it as a guide for Australian conditions rather than a promise.

Age still counts. Hot-climate vehicles in the Geotab data lost 0.4 percentage points more each year, and the warranty clock keeps running. BYD’s Australian warranty covers the battery and drive unit for 8 years or 160,000 km, with at least 70% capacity retention. At 10,000 km a year, you would reach only 80,000 km by the end of it. The years run out first.

Long stretches parked need a little planning, but not much:

• Charge level. Roughly 50 to 80% is the usual target for a long park, ideally out of the heat (EV Central, 2021). Check your owner’s manual, since manufacturers differ on whether to leave the car plugged in.
• Small battery. The 12V battery is the more likely problem. See our EV 12V battery guide before you go away for weeks.
• Tyres. Rubber ages even when kilometres don’t, so check the date code on a car that barely moves.

Petrol and diesel cars have their own low-use problems. Short trips leave moisture in the oil and can slowly drain the battery, according to carsales and RAA advice. RAA also warns that repeated short trips can clog a diesel particulate filter. If your current car is a diesel doing mostly short runs, that is a good reason to reconsider it.

When Keeping Your Current Car Wins

If your current car is healthy, safe and paid off, keeping it is often cheapest at low km. Using NRMA’s averages, a new small car loses more than $3,000 a year to depreciation. Fuel for 5,000 km costs only about $709 in a small petrol car.

A larger, thirstier car shifts that sum, but not as much as you might expect. Even at 10 L/100 km and $2.36/L, 5,000 km costs about $1,180 in fuel, which is still well below the depreciation hit on a new car. Many people can save more by running their existing car for a few more years, then buying once it starts costing real money.

Reasons to change anyway are perfectly valid. Your car might need big repairs, lack modern safety gear or be getting harder to climb into. You might want to stop visiting servos, or use your solar for something useful. Just don’t expect fuel savings to pay for the switch. If you are weighing timing, read should you buy an EV now or wait. And if you decide to change, our trade-in vs private sale guide can recover some of the difference.

Which Car Should Go Electric in a Two-Car Household?

Electrify the car that does the most kilometres, if it can do the job. Replacing a 20,000 km petrol car with an EV saves about $1,794 a year on the same assumptions. Replacing the 5,000 km runabout saves about $449. That is a fourfold difference from the same decision.

Plenty of households do it the other way, because the short-range runabout is the obvious fit for a cheap EV. That can still make sense when the long-distance car has to tow or cross areas with thin charging. It simply saves far less on fuel.

Expect some retraining if you drive both. Owners who run one of each commonly report two small annoyances. Strong regenerative braking feels odd after a petrol car, so the first few minutes in each need care. Some cars also move indicators or gear selectors to the opposite stalk. Softening the regen setting helps with the first problem. Time fixes the second. Many households also find the petrol car gets used less and less, which feeds straight back into the low-use problems above.

Retiring Soon? What to Do About a Novated Lease

If you are still on a salary, a novated lease can make an EV cheaper, but it needs careful timing. Treasury’s proposed FBT changes would keep the full exemption for eligible EVs valued at $75,000 or less if committed before 1 April 2029, with a 25% discount above that from 1 April 2027. Consultation closed on 28 September 2026, so check the final law before relying on it.

The catch is that lease payments come from your pay. When your salary stops, you generally have to pay out the lease or take over the finance. Some people near retirement consider a short lease and paying out the balance. A one-year lease has a 65.63% minimum residual under ATO rules, so you need a large lump sum at the end. Run it through our novated lease calculator and read what a residual payment means first. Our novated leasing hub has the wider rules.

Lower-km drivers also get less out of a lease’s running-cost packaging, because there is less fuel and maintenance to fund pre-tax. The FBT saving on the car remains. It is simply a bigger share of the deal.

Who Should Buy, and Who Shouldn’t

Your situation	Our call
Home by day, solar panels, about 10,000 km a year	Strong case for an EV
Solar, about 5,000 km a year, new car needed anyway	Buy the EV if the price is close
No solar or cheap off-peak rate, 5,000 km a year	Compare a hybrid, or keep your current car
Old car running fine, low repair bills	Keep it for now
Short-trip diesel that is starting to cost you	Worth replacing, and an EV suits this use well
Rarely home with no reliable charging	Probably not an EV yet

If you are retiring next year, there is no rush to pick a model today. New EVs keep arriving and prices keep moving. Use the time to test-drive a few, check seat height and ease of getting in, and get real insurance quotes. Those three things will tell you more than another fuel calculation.
