EV Range Calculator

Know your EV range under real conditions, not just lab tests. Your range gauge shows how far you can drive: Critical range (under 50 mi / 80 km) means you should plan a charge stop within the hour. Low range (50-150 mi / 80-240 km) covers daily commuting but limits long trips. Good range (150-300 mi / 240-480 km) is comfortable for most errands and moderate road trips — most modern EVs fall here. High range (300-400 mi / 480-640 km) means you can handle cross-country trips with confidence. Very High (400+ mi / 640+ km) is luxury EV territory with virtually no range anxiety. Cold weather reduces range 20-40%, highway speeds cut it 10-20%, and using heating in winter is the biggest battery drain.

The Formula

Range = (Battery / Efficiency) × 100 × Condition Factor.

Why It Matters

Your Tesla Model 3 has a 75 kWh battery using 0.25 kWh/mile. In perfect conditions you get 300 miles. In cold weather (0.8 factor), range drops to 240 miles — a 20% reduction. Planning 200-mile trips gives you a buffer.
