EV Charging After the 2026 Tariff Hike: Still Worth It?
22 June 2026 · 7 min read · PaperValue.sg
You've seen the headline: electricity is going up "significantly" from July. If you drive an EV, or you were about to buy one, you're doing quick mental math and getting nervous.
So let's skip the throat-clearing and answer the two questions you actually have:
- How much more will it cost me per charge?
- Is switching from petrol still worth it?
Short answers: about $4 more per full charge at home, and yes, comfortably. Now here's the detail, with real numbers for the cars people actually buy here.
How much more will one charge cost?
First, the number that matters. When the tariff rises, the cost of charging at home rises with it almost exactly, because home charging is billed at the regulated electricity rate (currently 29.72 cents/kWh including GST).
Analysts expect the July increase to land somewhere between a mid-single-digit bump and 30%, with most clustering around 20 to 25%. Let's use a 22% rise as the working assumption and see what it does to a full home charge.
| Your EV (battery) | Full charge now | After ~22% hike | Extra per charge |
|---|---|---|---|
| BYD Dolphin (~45 kWh) | ~$13 | ~$16 | +$3 |
| BYD Atto 3 (60.5 kWh) | ~$18 | ~$22 | +$4 |
| Tesla Model 3 (~60 kWh) | ~$18 | ~$22 | +$4 |
| BYD Seal (82.5 kWh) | ~$25 | ~$30 | +$5 |
Figures are for a 0 to 100% home charge at the regulated tariff. Real-world cost is a touch higher once you count about 10% charging losses.
So for the most popular EV on Singapore roads, the Atto 3, a full top-up at home goes from roughly $18 to about $22. Four dollars. Per full charge, which for most drivers is once or twice a week.
Put it another way: even in the worst-case 30% scenario, you're looking at an extra $5 to $6 per full charge on a mid-size EV. That's the price of a kopi and a kaya toast set.
What it adds up to over a month
You don't charge from empty to full every day, so the monthly figure is the honest one. A typical EV here covers 1,200 to 1,500 km a month and draws around 250 kWh to do it.
At today's rate, that's about $74 a month to "fuel" your car at home. After a 22% hike, roughly $90. The increase costs you around $16 a month, or about $4 a week.
That's the whole sting. Now the bigger question.
Is it still worth switching from petrol?
Here's the comparison that actually decides it. Let's put a home-charged EV next to a comparable petrol car, both doing 15,600 km a year (1,300 km a month), and look at fuel cost alone, after the tariff hike.
| Annual "fuel" cost | Per km | |
|---|---|---|
| EV, home charging (post-hike, ~36¢/kWh) | ~$905 | ~5.8¢ |
| EV, public charging (AC median ~67.5¢/kWh) | ~$1,685 | ~10.8¢ |
| Petrol (95-octane ~$2.70/litre after discounts, ~12 km/litre) | ~$3,510 | ~22.5¢ |
Read that bottom row again. Even with the tariff increase fully baked in, charging an EV at home costs roughly a quarter of what petrol costs to run the same distance. You'd save around $2,600 a year on fuel by going electric, and the tariff hike only shaved about $160 off that advantage.
The "is it worth it" question doesn't get close to flipping. The hike makes EV charging slightly less of a steal. It does not make petrol competitive.
The catch: it depends entirely on where you charge
Notice the middle row of that table. If you can't charge at home, the reality for many HDB residents, and you rely on public chargers, your annual fuel cost jumps to around $1,685. Still well below petrol's $3,510, so you're saving roughly $1,800 a year. But it's half the saving of a home charger, and you trade away the overnight-and-forget convenience.
This is the single biggest variable in your decision, far bigger than the tariff:
- Home charger (landed, or condo with a wallbox): maximum savings, minimum hassle. The EV case is overwhelming.
- Public charging only (most HDB flats): still cheaper than petrol, but the margin is thinner and you're at the mercy of charger availability and operator pricing.
One more wrinkle for public chargers: operators set their own rates from their own energy contracts, so the tariff hike won't hit them instantly. But a big rise will likely filter through over the following weeks, on top of an already higher base. If your brand offers a charging perk (BYD owners get 25% off Shell Recharge, for instance), use it. It can wipe out the increase entirely.
So what should you actually do?
If you already drive an EV: nothing. Absorb the extra $4 a week and carry on. You're still paying a fraction of what your petrol-driving neighbour does, and analysts expect the tariff to ease again from late 2026 into 2027 if Middle East oil flows normalise.
If you're deciding whether to switch: the running-cost case for an EV survives this hike intact, provided you can charge at home or have reliable cheap charging nearby. If you're HDB with no good charging option, the savings are real but smaller, so run your own numbers before committing.
And remember fuel is only one line of the budget. COE, depreciation, and the ARF dwarf what you spend charging, and a $16-a-month tariff swing shouldn't be the thing that decides a five-figure car purchase. Look at the total cost of ownership, not the pump-versus-plug snapshot of a single volatile quarter.

Frequently Asked Questions
How much does it cost to fully charge an EV in Singapore?
At home, a full charge runs about $13 for a small EV (Dolphin), $18 for a mid-size one (Atto 3), and $25 for a large battery (Seal) at current rates. After the expected July 2026 tariff hike, add roughly $3 to $5 per full charge.
How much more will EV charging cost after the July 2026 tariff increase?
For a home charger, expect around $16 more a month, or about $4 per full charge of a mid-size EV, if the consensus 20 to 25% tariff increase holds. Charging losses add a little more in practice.
Is it cheaper to drive an EV than a petrol car in 2026?
Yes. Even after the tariff hike, charging at home costs about 5.8 cents per km versus roughly 22 to 25 cents for petrol, around four times cheaper. Public charging is pricier but still well below petrol.
Should I still switch to an EV with electricity prices rising?
If you can charge at home, the savings (around $2,600 a year on fuel) make the case easily, even post-hike. If you depend on public charging, you'll still save, closer to $1,800 a year, but weigh the convenience trade-off carefully.
Will the tariff keep rising?
EMA has warned of further increases later in 2026, but several analysts expect the tariff to start falling again from the fourth quarter of 2026 or early 2027 if oil and gas supply normalises. It's cyclical, not a permanent step-change.
Does home charging really cost the same as the electricity tariff?
Effectively yes. A home wallbox draws electricity at your regulated tariff rate (or your retailer's fixed-price plan), so it tracks the quarterly tariff directly, unlike public chargers, which set their own per-kWh prices.
