EV Range Calculator
Estimate how far an electric vehicle can travel on a given battery charge using its efficiency in kWh per 100km.

Calculation breakdown
- Range
- Range = (usable battery kWh / kWh per 100km) × 100
Worked example
A 60kWh usable battery at 16kWh/100km gives an estimated range of about 375km.
Assumptions
- Real-world range varies with speed, terrain and climate control use.
- Battery degradation reduces usable capacity over time.
How this calculator works
Divide your electric vehicle's usable battery capacity by its energy consumption rate to estimate driving range on a full charge. Real-world range varies with driving speed, climate control use, terrain and battery degradation over time.
Frequently asked questions
Why is my real range less than the advertised figure?
Advertised range is usually from standardised testing; highway speeds, cold weather, hilly terrain and cabin heating or cooling all reduce real-world range.
What efficiency figure should I use?
Check your EV's trip computer for your actual average kWh/100km, which is usually more accurate than the manufacturer's claimed figure.
Does battery age affect this?
Yes, battery capacity gradually degrades over years of use, which reduces the usable kWh available and therefore range.
