What is EV Savings?
An EV savings calculator compares the total running costs of an electric vehicle versus a petrol car, including fuel/charging, servicing, registration, and tax benefits.
How this calculator works
The calculator compares cost-per-kilometre for both vehicle types. Petrol cost is calculated from fuel consumption (L/100km) and fuel price. EV cost uses energy efficiency (kWh/100km) and electricity rate. It then adds estimated service savings (~$700/year — EVs have fewer moving parts) and registration savings. The CO₂ calculation uses the standard 2.31 kg per litre of petrol consumed. The FBT exemption note highlights that eligible EVs are exempt from Fringe Benefits Tax in Australia — a significant saving for salary-packaged vehicles.
Running Cost Comparison
Petrol car at 8L/100km × $1.80/L = $14.40 per 100km (~14¢/km). EV at 18 kWh/100km × $0.30/kWh = $5.40 per 100km (~5¢/km). For 15,000 km/year: petrol $2,160 vs EV $810 = saves $1,350/yr on fuel alone. Add ~$700/yr servicing savings (EVs have far fewer moving parts) = $2,000+/yr running cost savings.
EV FBT Exemption (Biggest Tax Advantage)
Per Treasury Laws Amendment (Electric Car Discount) Act 2022, eligible EVs under the LCT threshold ($91,387 for fuel-efficient vehicles 2024-25) are FBT-EXEMPT for novated leases. Saves $5k-$15k/yr for high earners. Pure EVs remain exempt indefinitely; PHEVs lose exemption 1 April 2025. The exemption applies to: pure battery EVs, hydrogen fuel-cell vehicles.
State EV Incentives
ACT: FREE rego for zero-emission vehicles. NSW: $3,000 rebate (first 25,000 — now closed) + stamp duty exemption to $78,000. VIC: $3,000 rebate (closed) + $100/yr rego discount. QLD: 50% rego discount + $6,000 rebate (closed 2023). WA: $3,500 rebate. TAS: 2 years free rego. Always check current state schemes.
Home Charging Costs
Standard 240V outlet (Level 1): 8-12 kWh/hr, slow but free to install. Adds 50-100 km overnight. 7-22 kW wallbox (Level 2): adds 40-150 km/hr, costs $1,500-$3,000 installed. Solar-charged: effectively free if you have excess solar export — best ROI for solar+EV combo. Public DC fast charging: $0.40-$0.65/kWh — more expensive than home but necessary for long trips.
