Price the Vehicle and the Charging Routine Together
An EV can use cheaper energy per kilometre and still cost more across five years. A hybrid can cost less upfront and still lose if high mileage makes its fuel bill dominate. Compare value loss, energy, tax, insurance and maintenance, then reject any EV case that depends on charging access your household cannot repeat.
Two-part rule
The EV must pass both the five-year cost test and the ordinary-week charging test. Passing only one does not make it a robust household choice.
Apply the 2026 rules once
NEA and LTA state that from 1 January 2026 the revised VES incentivises fully electric vehicles only; hybrid vehicles no longer receive VES rebates. For an eligible fully electric car registered in 2026, the EV Early Adoption Incentive is 45% of ARF capped at S$7,500, and the VES A-band rebate is S$22,500. The stated combined maximum is S$30,000. EEAI ceases from 1 January 2027.
Use a final drive-away quote after incentives. Do not subtract EEAI or VES again in the worksheet. Also record net ARF: LTA explains that rebates reduce the ARF basis used for later PARF calculations.
Use one five-year cost boundary
Five-year cost = purchase price − exit proceeds + energy + road tax and insurance + maintenance + charging-access costs.
Add financing only when the payment method differs. Keep parking, ERP and other truly equal costs out of both columns.
Worked example: mixed charging versus hybrid fuel
All figures below are hypothetical. They show the calculation, not a quote or forecast. Both prices are assumed to be all-in after applicable rebates or surcharges.
| Input | Hybrid | EV |
|---|---|---|
| All-in purchase price | S$136,000 | S$142,000 |
| Exit proceeds after five years | S$48,000 | S$50,000 |
| Five-year value loss | S$88,000 | S$92,000 |
| Annual distance | 16,000 km | |
| Energy use | 4.8 L/100 km | 18.2 kWh/100 km, including assumed charging losses |
| Energy price | S$2.80/L | 70% at S$0.35/kWh; 30% at S$0.65/kWh |
The EV's weighted charging price is (70% × S$0.35) + (30% × S$0.65) = S$0.44/kWh.
Calculate energy on the same distance
| Energy calculation | Hybrid | EV |
|---|---|---|
| Annual energy | 16,000 × 4.8 ÷ 100 = 768 L | 16,000 × 18.2 ÷ 100 = 2,912 kWh |
| Annual cost | 768 × S$2.80 = S$2,150.40 | 2,912 × S$0.44 = S$1,281.28 |
| Five-year cost | S$10,752 | S$6,406.40 |
| EV energy saving | S$4,345.60 over five years | |
Complete the five-year total
| Five-year item | Hybrid | EV |
|---|---|---|
| Value loss | S$88,000 | S$92,000 |
| Fuel or electricity | S$10,752 | S$6,406.40 |
| Road tax and insurance | S$13,750 | S$17,980 |
| Maintenance allowance | S$4,000 | S$2,500 |
| Charging access or subscription | S$0 | S$600 |
| Total | S$116,502 | S$119,486.40 |
In this base case, the hybrid costs S$2,984.40 less. The EV's energy and maintenance advantage does not recover its higher value loss, tax, insurance and charging-access costs.
Test a public-charging-heavy case
If all EV charging costs S$0.65/kWh, five-year electricity becomes 2,912 × S$0.65 × 5 = S$9,464. That is S$3,057.60 above the mixed-charging case, raising the EV total to S$122,544.
Use the rates at chargers you can actually access, including any idle, parking or subscription charges. A household electricity tariff is useful context only when the car can charge under that arrangement. Public charging operators set their own prices.
Pass the ordinary-week charging test
| Question | Evidence required | Fail signal |
|---|---|---|
| Where will the car charge? | Name primary and backup chargers | “Near home somewhere” |
| When is the charging window? | Two repeatable weekly time blocks | Depends on a last-minute detour |
| What price mix is realistic? | Share of kWh at each accessible rate | All energy priced at the cheapest advertised rate |
| What if a charger is occupied? | Backup location and added time | No workable alternative before the next critical trip |
| Can access change? | Parking tenure, workplace policy or nearby network plan | The cost case depends on access the buyer does not control |
LTA provides real-time public charging-point availability in MyTransport.SG. Use it to observe the intended locations at the times you would normally charge; it does not replace a fallback plan.
Verify tax rather than estimating from the badge
LTA calculates petrol-electric road tax from both engine capacity and maximum motor power, with the higher amount payable. Fully electric road tax is based on power rating and includes the Additional Flat Component, currently S$700 a year. Obtain the exact annual amounts for both variants before finalising the table.
Write the decision trigger
“We choose the EV only if its weak-case five-year premium stays below S$[amount], at least [share]% of charging is available at or below S$[rate]/kWh, and two weekly charging windows plus one fallback remain practical.”
If the EV fails the routine, price the hybrid against petrol. If charging is available but full EV feels premature, test whether a PHEV will really cover enough kilometres electrically.
FAQ
Is an EV always cheaper to run than a hybrid in Singapore?
No. Electricity can cost less per kilometre, but the result also depends on purchase price, exit value, road tax, insurance, maintenance and the price mix of the chargers you can actually use.
What 2026 incentives apply to fully electric cars?
For an eligible fully electric car registered in 2026, EEAI provides 45% off ARF capped at S$7,500, while the VES A-band rebate is S$22,500. The combined stated maximum is S$30,000. Use an all-in quote so these benefits are not counted twice.
Do hybrids receive a 2026 VES rebate?
No. Hybrid vehicles no longer receive VES rebates from 1 January 2026. Check the exact model's band because a neutral outcome or surcharge can still affect the quote.
How should I test EV charging fit?
Name the chargers, access hours, expected price, weekly charging windows and fallback for an unavailable charger. Calculate cost using that charging-price mix rather than the cheapest advertised rate.
