EV vs Petrol Car Singapore 2026: The 10-Year Total Cost, Honestly

The question every Singaporean car buyer now asks: is an EV actually cheaper over 10 years? The sales pitch says yes. The petrol loyalist says no, batteries. Both are deflecting the real math.

This article breaks down every 10-year cost line for a comparable electric and petrol car in 2026. Plug your own mileage and charging pattern into the EV vs ICE Calculator to see your number.

Is an EV actually cheaper than a petrol car in Singapore?

Yes, for most profiles. By how much depends on mileage.

Representative 2026 comparison — Cat A family sedan, 15,000 km/year, home charging:

Cost line	EV (Cat A, ~110 kW)	Petrol (Cat A, 1.6L)
Upfront purchase (OMV + ARF + COE)	~S$170,000	~S$145,000
Annual fuel / charging	~S$765	~S$3,255
Annual road tax	~S$952	~S$744
Annual insurance	~S$2,400	~S$1,800
Annual servicing	~S$500	~S$1,000
Annual running	~S$4,617	~S$6,799
10-year running	S$46,170	S$67,990
PARF rebate (year 10)	S$20,000	S$13,500
Net 10-year cost	S$196,170	S$199,490

Delta: EV saves S$3,320 over 10 years at 15,000 km/year in this example. Bump mileage to 25,000 km/year and the saving jumps past S$20,000. Drop to 8,000 km/year and the ICE can actually win on total cost.

What is the EV road tax in Singapore 2026?

LTA overhauled EV road tax in the 2024 budget — removed the "additional usage charge" that used to add hundreds of dollars per year. The current schedule is kW-based in stepped bands:

Motor power	Annual road tax (2026)
≤ 7.5 kW	S$400
≤ 32.5 kW	S$608
≤ 70 kW	S$752
≤ 230 kW	S$952 + (kW − 70) × S$1.60
> 230 kW	S$2,158 + (kW − 230) × S$2.40

For context: a Tesla Model 3 RWD (208 kW) pays ~S$1,173/year. A BYD Atto 3 (150 kW) pays ~S$1,080/year. A Cat A petrol 1.6L pays ~S$744, a 2.0L pays ~S$1,510 — so EV road tax sits squarely in the same range as comparable-size petrol cars.

How much does it cost to charge an EV in Singapore?

Depends on your home setup and how often you hit public fast chargers.

Home charging (most owners with a landed property or condo with charger):

• SP Group regulated tariff: ~S$0.30/kWh
• 17 kWh/100km sedan consumption
• ~S$5.10 per 100 km = S$0.051/km
• 15,000 km/year → S$765

Public DC fast charging (SP Mobility, Shell Recharge, BlueSG):

• Typical S$0.55/kWh
• Same consumption: ~S$9.35 per 100 km
• 15,000 km/year → S$1,400

Realistic mix for most condo dwellers (home charger available ~70% of the time):

• Blended S$0.38/kWh → ~S$970/year

Compare petrol at S$3.10/L × 7 L/100km consumption = S$3,255/year at 15,000 km. That's a S$2,300 annual gap — most of the EV's savings case comes from this one line.

Do EVs hold their value in Singapore?

Mixed picture. First 3 years depreciation on EVs is slightly steeper than comparable petrol cars (roughly 40–45% of purchase vs 35–40% for petrol) — because tech moves fast and 3-year-old EVs look outdated next to new models.

After year 5, depreciation curves converge. By year 10, the PARF rebate (50% of ARF paid) is the main "residual value" for both. Because EV ARF is higher (higher OMV → more ARF), the PARF rebate in absolute S$ is higher. But as a percentage of original purchase, they end up similar.

Practical rule: if you plan to keep the car 8+ years, depreciation is a wash. If you plan to flip at 3 years, petrol holds value slightly better today.

What about battery replacement cost?

The single most-Googled EV concern in Singapore, and the least likely to actually bite.

Manufacturer warranties:

• Tesla: 8 years / 160,000 km, minimum 70% capacity retention
• BYD: 8 years / 150,000 km
• Hyundai Kona EV: 8 years / 160,000 km
• Polestar / Volvo: 8 years / 160,000 km

Real-world degradation data from large fleet studies shows 10–15% capacity loss after 10 years of normal use. A 60 kWh pack with 15% loss still delivers 51 kWh of usable range — for a 15 kWh/100km EV, that's 340 km per charge, fine for SG commuting forever.

Replacement cost if you actually need it: S$15,000–S$30,000 depending on pack size and sourcing (Tesla direct vs third-party refurb). But given most SG EVs scrap or get renewed at year 10 (COE expiry), most owners never face the decision.

Bottom line

For the median SG profile — Cat A car, 12,000–18,000 km/year, condo-dweller with home charger — EV wins by S$3,000–S$20,000 over 10 years. The number skews higher with more mileage and home-charging share.

EV loses if:

• You drive <8,000 km/year (running-cost savings don't cover the upfront premium)
• You have no home charger and rely fully on public charging (public DC rates erode most of the fuel savings)
• You flip cars every 3 years (depreciation penalty)
