EV Charging Cost in Malaysia: Home Calculator by Battery Size and TNB Tariff

11 minutes ago
6 min read

Charging a typical EV at home overnight on TNB's off-peak rate costs roughly RM6 to RM7 per 100km driven in 2027 - about a third of subsidised petrol and up to a quarter of public DC fast charging. The exact figure depends on your battery size and which TNB tariff you're on, so this guide builds the full calculator below: TNB's actual 2027 rates, cost per 100km across every charging method, and a battery-by-battery cost table for five popular EV sizes sold in Malaysia.



The 60-Second Answer

  • Home charging on TNB's domestic tariff costs between 41.83 sen/kWh (off-peak Time-of-Use) and 44.43 sen/kWh (standard flat rate) all-in as of 2027.

  • That works out to roughly RM6.27-RM6.66 per 100km driven, assuming a 15kWh/100km consumption rate.

  • Public AC charging (Gentari, 7-22kW) costs about RM1.00-RM1.15/kWh - roughly RM15.75 per 100km, more than double the home rate.

  • Public DC fast charging costs RM1.30-RM1.80/kWh depending on network and site type, or RM19.50-RM27.00 per 100km - sometimes more expensive than subsidised petrol.

  • A 60kWh battery (like the BYD Atto 3) costs about RM22.59 to charge from 10% to full at home overnight; a 30kWh battery (Proton e.MAS 5) costs about RM11.29.


What 'EV Charging Cost Calculator' Searches Actually Mean

Buyers searching this term usually want one of three things: a rough monthly electricity bill estimate before buying a wallbox, a side-by-side versus petrol to justify the switch, or clarity on whether public chargers are cheap enough to skip home installation altogether.


There's also a common misconception worth clearing up immediately: TNB's old five-tier block tariff (21.8 sen for the first 200kWh, rising to 57.1 sen above 900kWh) no longer applies. Under the RP4 restructuring that took effect 1 July 2025, domestic electricity moved to a simpler flat-rate structure, and any calculator still using the old blocks will overstate your bill.


TNB Domestic Tariff 2026-2027: What You're Actually Billed

Tariff type

When it applies

Base rate

All-in effective rate

General (flat), ≤1,500 kWh/month

Any time of day

27.03 sen/kWh energy + 4.55 sen capacity + 12.85 sen network

44.43 sen/kWh

General (flat), >1,500 kWh/month

Any time of day

37.03 sen/kWh energy + 4.55 sen capacity + 12.85 sen network

54.43 sen/kWh

Time-of-Use (ToU) Peak

2pm-10pm, weekdays only

28.52 sen/kWh energy + 4.55 + 12.85

45.92 sen/kWh

Time-of-Use (ToU) Off-Peak

10pm-2pm weekdays + all-day weekends/public holidays

24.43 sen/kWh energy + 4.55 + 12.85

41.83 sen/kWh

If you can charge overnight or on weekends, switching to ToU and plugging in during off-peak hours is the cheapest legitimate option on TNB's books. Most EV owners on a Guru Swift Advance wallbox simply schedule a timer-delayed charge to land inside the off-peak window.


Cost Per 100km: Home vs Public AC vs Public DC vs Petrol

Assuming a consumption rate of 15kWh per 100km - a reasonable average across Malaysia's compact-to-mid-size EV range, though actual consumption varies with driving style, air-conditioning use, and traffic - here's what 100km actually costs under each option.

Method

Rate used

Cost per 100km

Home, TNB ToU off-peak

41.83 sen/kWh

RM6.27

Home, TNB standard domestic

44.43 sen/kWh

RM6.66

Public AC (Gentari, 7-22kW)

~RM1.00-1.15/kWh

~RM15.75

Public DC fast charging

RM1.30-1.80/kWh

RM19.50-RM27.00

Petrol, subsidised RON95 (BUDI95), 7L/100km

RM1.99/litre

RM13.93

Public DC fast charging at its most expensive sites can cost nearly double subsidised RON95 petrol per 100km. That's not a criticism of public charging networks - DC is built for highway top-ups and emergencies, not daily commuting - but it means a home wallbox is where the real monthly savings come from.


Home Charging Cost by Battery Size: Five Popular EVs

Here's what it costs to charge from roughly 10% to full at home on TNB's off-peak rate, across five battery sizes commonly sold in Malaysia in 2026-2027.

Battery size / example model

Energy added (10%→100%)

Cost at home off-peak (41.83 sen)

Approx. range added*

30.12 kWh - Proton e.MAS 5 Prime

27.0 kWh

RM11.29

~180 km

49.52 kWh - Proton e.MAS 7 Prime

44.6 kWh

RM18.64

~297 km

60 kWh - BYD Atto 3

54.0 kWh

RM22.59

~360 km

78.4 kWh - Tesla Model 3 Long Range

70.6 kWh

RM29.52

~470 km

90 kWh - Maxus MIFA 9 Luxury

81.0 kWh

RM33.88

~540 km

*Range estimates use the same 15kWh/100km assumption applied above for consistency across models - not each manufacturer's own efficiency figure, since those vary by test cycle. Battery specifications are sourced from published model data; none are estimated.

The one mistake to avoid: don't plug the old TNB block-tariff numbers (21.8 sen, 33.4 sen, and so on) into a spreadsheet to estimate your EV charging bill. That structure was scrapped in July 2025. Using it will make home charging look either far cheaper or far costlier than it actually is, and either way you'll misjudge the real monthly saving against petrol.


Homeowners vs JMB/Commercial: Who Pays What

For a landed homeowner, the calculation above is the whole story: one meter, one tariff, overnight charging on your own wallbox. A single-phase installation from EVGuru starts from RM1,679, with three-phase setups for higher-power 11-22kW charging from RM1,749 - see the full landed-home installation guide for what determines which you need.


For condo residents and JMB committees, the maths changes because charging usually runs through shared building supply or individually sub-metered bays rather than a single domestic account. Cost allocation, cabling runs, and ST compliance all need planning before residents can charge at TNB domestic rates at all - our condo/JMB page covers how that's structured.


Commercial operators - offices, car parks, corporates installing bays for staff or visitors - run on commercial tariffs, not domestic ones, and the cost model looks different again. Businesses investing in EV charging infrastructure can currently claim Green Investment Tax Allowance (GITA) for qualifying assets up to 31 December 2026; see our commercial charging page for project-specific quotes.


FAQ

How much does it cost to charge an EV at home in Malaysia per month?

For a driver covering about 1,200km a month in a compact EV at 15kWh/100km, home charging on TNB's off-peak rate costs roughly RM75 a month, versus around RM167 for the subsidised petrol equivalent. Actual cost scales with your real consumption and how much of your charging lands inside the off-peak window.


Does TNB still use the old first-200kWh block tariff for EV charging calculations?

No. Since 1 July 2025, TNB replaced the five-tier block structure with a flat domestic rate of 27.03 sen/kWh up to 1,500kWh a month (37.03 sen/kWh above that), plus capacity and network charges. Any calculator still quoting 21.8 sen or 57.1 sen is using a retired rate.


Is charging an EV at a public DC fast charger cheaper than petrol in Malaysia?

Not reliably. At RM1.30-1.80/kWh, public DC fast charging works out to roughly RM19.50-RM27.00 per 100km, which is often higher than subsidised RON95 petrol at around RM13.93 per 100km. DC charging is best reserved for road trips and top-ups, not daily use.


Will charging my EV at home push my TNB bill into a higher tariff band?

Usually not. The 2026 flat-rate structure has only one step, at 1,500kWh of total household usage a month. Adding 150-250kWh for typical EV charging rarely pushes an average household over that threshold, though very high-usage homes should keep an eye on total consumption.


Which battery size is cheapest to charge at home?

In absolute terms, the smallest battery costs the least per full charge - about RM11 for a 30kWh Proton e.MAS 5 versus roughly RM34 for a 90kWh Maxus MIFA 9. But the rate per kWh is identical across all sizes, so cost per kilometre driven stays roughly the same; a bigger battery just means a bigger one-time top-up for more range.
