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

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:

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.

The Singapore-Specific Distortions

A 10-year ownership comparison in Singapore looks different from anywhere else in the world because three line items are unique:

COE is fuel-agnostic. A Cat A COE costs the same whether you're putting it on a Toyota Corolla Altis or a BYD Atto 3. This neutralises one of the biggest EV disadvantages globally — the upfront premium — by socialising a S$90,000+ per-car licence fee across all powertrains. In effect, the COE shrinks the percentage gap between EV and ICE.

ARF favours ICE on cheap cars but EV on premium cars. ARF is a tiered tax on Open Market Value (OMV). EVs have higher OMV than equivalent ICE cars (the battery), so ARF is higher in absolute terms. But EVs benefit from incentives (below) that net out the ARF gap.

Road tax is computed differently for the two powertrains. EVs by motor power (kW); ICE by engine displacement. The 2024 reform brought these closer together but they still bias slightly differently across the size spectrum.

EV Early Adoption Incentive (EEAI) and VES — both stepped down for 2026

Two government schemes materially change the EV math, but BOTH have been pared back for 2026, and EEAI ends entirely on 31 December 2026.

EV Early Adoption Incentive (EEAI) provides 45% off ARF, with the cap reduced over time:

The $5,000 minimum ARF floor only applied to 2021 EV registrations. For 2022–2027 EV registrations, there is no ARF floor — ARF can go to zero after rebates.

Vehicular Emissions Scheme (VES) — revised for 1 Jan 2026 – 31 Dec 2027. Bands relabelled A / B / C1 / C2 / C3 (replacing A1/A2/B/C1/C2). Pollutant thresholds unchanged but mapped differently. Band A car rebates:

Surcharges of up to $25,000 still apply to the dirtiest emissions bands.

Stacked 2026 EV incentive math: $22,500 (VES Band A) + $7,500 (EEAI) = $30,000 in ARF reductions versus the headline ARF schedule. Buyers registering in 2027 lose the $7,500 EEAI entirely and the VES rebate drops to $20,000 — a $10,000 narrowing of the EV-vs-ICE upfront gap in a single year.

Any 10-year TCO calculator that assumed permanent EEAI is now overstating EV total savings. After 31 Dec 2026, the upfront EV premium widens by the lost EEAI, and the break-even crossover moves from year 5–6 to year 7–8 for a typical Cat A buyer.

What is the EV road tax in Singapore 2026?

EV road tax is based on motor Power Rating (PR in kW) plus an Additional Flat Component (AFC) of $350 per 6 months ($700/year, in place since 1 Jan 2023). Many older guides omit the AFC — make sure your TCO model includes it.

The 6-monthly road-tax formula:

Annual road tax = 2× 6-monthly amount + $700 AFC.

Worked examples (annual, including AFC):

• BYD Atto 3 (150 kW): 2 × [250 + 3.75(120)] × 0.782 + 700 = 2 × $547.40 + $700 = ~$1,795/year
• Tesla Model 3 RWD (208 kW): 2 × [250 + 3.75(178)] × 0.782 + 700 = 2 × $717.49 + $700 = ~$2,135/year
• Tesla Model S Plaid (760 kW): 2 × [1,525 + 10(530)] × 0.782 + 700 = 2 × $5,338.65 + $700 = **$11,377/year**

Compare with ICE: a Cat A petrol 1.6L pays ~$1,180/year; a 2.0L pays ~$2,100/year. EV road tax sits in the same ballpark as comparable-size petrol cars once AFC is included, with high-power EVs paying meaningfully more.

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

• SP Group regulated tariff: ~S$0.30/kWh (commercial off-peak rates can drop to ~S$0.25)
• 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, ChargePoint):

• Typical S$0.55/kWh, peak rates up to S$0.70/kWh at premium locations
• 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. Premium 95 has been trending S$2.80–S$3.20/L through 2024–2026; charging tariffs have been more stable, which adds an additional risk-adjusted edge to EVs over a 10-year horizon.

Charging Infrastructure Status in Singapore

The 2026 reality is mixed. URA and LTA targets call for 60,000 charging points by 2030, with at least one EV-ready lot in every HDB carpark by 2025. Progress as of early 2026:

• HDB carparks: ~2,000 of 2,000+ carparks now have at least one charger; rollout to multiple bays per carpark is underway. Mostly AC chargers at S$0.55–S$0.65/kWh.
• Condominiums: patchy. Some MCSTs have approved building-wide installations; others block individual lot installations citing electrical capacity. Buyers should confirm condo charger availability before signing.
• Landed: straightforward — home installation costs S$1,500–S$3,500 for a 7 kW charger plus electrician fees.
• Public DC fast chargers: 1,000+ across the island; clustered around shopping malls, petrol stations being repurposed, and major arterials.

If you live in a no-charger condo and have no realistic prospect of installing one, run the math at the public-charging price line — most of the EV cost advantage evaporates.

Servicing Differences

EVs are mechanically simpler, which shows up in maintenance bills:

• No engine oil or filter changes (~S$300/year saved)
• No spark plugs, timing belts, exhaust system, or clutch
• Brake pads last 2–3× longer thanks to regenerative braking
• Fewer wear parts — no transmission fluid, no fuel filters

Typical EV servicing in Singapore: ~S$400–S$600/year for a Tesla, BYD, or Hyundai/Kia EV. Comparable ICE: ~S$900–S$1,200/year for a Cat A sedan, more for European brands. Over 10 years, this is a S$5,000+ saving in EVs' favour, even before factoring in the higher reliability of electric drivetrains.

Insurance Differences

EVs cost roughly 20–35% more to insure in Singapore today. Three reasons:

1. Higher repair costs — battery damage from minor accidents can write off the car. Workshops have fewer EV-certified technicians and panel parts cost more.
2. Higher OMV drives higher sum insured.
3. Less actuarial data — insurers price uncertainty into premiums until they have 5–10 years of EV claims history.

Worked: a Tesla Model 3 RWD owner paying S$2,400/year for comprehensive cover; an equivalent Toyota Corolla Altis owner pays S$1,800/year. The S$600 gap closes about half-way over a decade as insurers gather data.

Battery Replacement Risk

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 indefinitely.

Replacement cost if you actually need it: S$15,000–S$30,000 depending on pack size and sourcing (manufacturer-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. The only buyers who should price in a battery swap are those planning to renew COE at year 10 and run the car to year 15 or 20.

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. Tesla's price cuts in 2023–2024 specifically punished early-adopter resale.

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.

Singapore's used-EV market is also strengthening: limited supply (because new-car COE keeps demand high) plus growing acceptance of EVs has lifted 5-year-old Tesla and BYD valuations relative to global benchmarks. A 5-year-old Model 3 in 2026 holds more PARF-relative value than the equivalent in California or Sydney.

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.

Worked Example: Tesla Model 3 vs Toyota Camry, 10 Years

Stylised 2026 scenario, 15,000 km/year, 70% home + 30% public charging:

Tesla wins by ~S$6,300 over 10 years — narrower than the Cat A example because of higher COE, higher insurance, and larger battery weighing into road tax. Drop the Camry to a 1.6L Cat A car and the gap widens; bump the Tesla to a Long Range with a heavier battery and higher kW band, the gap narrows.

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)
• The EEAI lapses without replacement and you're buying in 2026+ (S$45k upfront swing)

Run your own numbers through the EV vs ICE Calculator and the break-even year will tell you whether EV math works for you specifically.
