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.

Miles per month

EV efficiency (Wh/mi)

Electricity price (p/kWh)

Charging losses (%)

Petrol price (£/L)

Petrol car efficiency (mpg UK)

Uses UK gallons (4.546L). Results are indicative.

Charging Cost per Mile

Quick cost per mile and per 100 miles for any tariff.

Electricity price (p/kWh)

Efficiency (Wh/mi)

Charging losses (%)

Miles (optional)

Great for comparing home vs public rapid charging.

CO₂ Emissions (EV vs Petrol)

Estimate trip CO₂ and savings.

Trip miles

EV efficiency (Wh/mi)

Grid intensity (gCO₂/kWh)

Charging losses (%)

Petrol mpg (UK)

Petrol CO₂ kg/L

Charging Time Estimator

Estimate charging time from SOC A → SOC B.

Usable battery (kWh)

Charger power (kW)

Start SOC (%)

End SOC (%)

Average power factor

Session overhead (minutes)

Real charging is not constant kW; factor approximates tapering.

Real-World Range Estimator

Estimate miles available with reserve.

Usable battery (kWh)

Efficiency (Wh/mi)

Current SOC (%)

Reserve to keep (%)

Driving conditions

Extra load (kg)

Load penalty uses a light heuristic (+~1% Wh/mi per 100kg).

Winter Range Impact

See how cold weather can change your range and cost.

Baseline efficiency (Wh/mi)

Winter penalty (%)

Battery usable (kWh)

Electricity price (p/kWh)

Simple model: winter increases Wh/mi by selected %.

Shared Trip Cost Splitter

Perfect for ridesharing — split charging cost fairly.

Trip miles

Passengers (excluding driver)

Efficiency (Wh/mi)

Electricity price (p/kWh)

Charging losses (%)

Driver contribution (%)

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.
