EV vs Petrol Calculation Guide (Step-by-Step)

Here is how to calculate EV vs petrol cost manually:

Step 1: Calculate EV Cost

Formula:

EV Cost = (Distance × EV Consumption ÷ 100) × Electricity Price

Example:

Distance = 1000 km/month, EV consumption = 15 kWh/100 km, Electricity price = $0.15/kWh

EV Cost = (1000 × 15 ÷ 100) × 0.15 = $22.5 per month

Step 2: Calculate Petrol Cost

Formula:

Petrol Cost = Distance ÷ Mileage × Petrol Price

Example:

Distance = 1000 km, Mileage = 15 km/l, Petrol price = $1.2/l

Petrol Cost = 1000 ÷ 15 × 1.2 = $80 per month

Step 3: Calculate Savings

Savings = Petrol Cost − EV Cost

Savings = 80 − 22.5 = $57.5 per month

EV vs Petrol Conversion Chart

Distance (km/month) EV Cost ($) Petrol Cost ($) Savings ($)
500 11.25 40 28.75
1000 22.5 80 57.5
1500 33.75 120 86.25
2000 45 160 115
3000 67.5 240 172.5

Assumptions: EV: 15 kWh/100 km, $0.15/kWh | Petrol: 15 km/l, $1.2/l
