EV Cost & Charging Calculators
Compare running costs, charging tariffs and CO₂ impact using real UK values.
Free UK-friendly calculators to help EV drivers plan range, charging, and costs.
EV vs Petrol Cost
Compare running cost per mile and monthly cost.
Uses UK gallons (4.546L). Results are indicative.
Charging Cost per Mile
Quick cost per mile and per 100 miles for any tariff.
Great for comparing home vs public rapid charging.
CO₂ Emissions (EV vs Petrol)
Estimate trip CO₂ and savings.
Charging Time Estimator
Estimate charging time from SOC A → SOC B.
Real charging is not constant kW; factor approximates tapering.
Real-World Range Estimator
Estimate miles available with reserve.
Load penalty uses a light heuristic (+~1% Wh/mi per 100kg).
Winter Range Impact
See how cold weather can change your range and cost.
Simple model: winter increases Wh/mi by selected %.
Shared Trip Cost Splitter
Perfect for ridesharing — split charging cost fairly.
Driver contribution lets you subsidise (e.g., 20% driver covers). Set 0 to split equally.
Next: Live Chargers on Rides
We can connect rides to a live charger map via Zapmap Spark (UK). This requires a small proxy to protect the API key.
