- Real-world range
- 205 miles
- Ideal range
- 268 miles
- Usable battery
- 67.5 kWh
- Cost per 100 miles at $0.15/kWh
- $4.20
Quick answer
Real EV range is battery capacity divided by consumption, reduced by cold weather and speed.
Range = usable kWh ÷ kWh per mile

Frequently asked questions
How much range does cold cost?
10–25% below freezing, mostly from cabin heating.
Why keep a reserve?
Charging above 80% and below 10% is slow and stresses the pack.
What do I need to enter into the EV Range Calculator?
Just 4 values: battery capacity, consumption, cold weather loss, reserve buffer. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the EV Range Calculator work out the answer?
Real EV range is battery capacity divided by consumption, reduced by cold weather and speed. It applies the formula Range = usable kWh ÷ kWh per mile and shows the working so you can check each step by hand.
Is the EV Range Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
