How to Use This Calculator

Enter the estimated Full Charge Cycles (approximate full discharge + recharge cycles since new).
Set the Average Climate Temperature (°F) where the car is typically kept — heat accelerates degradation.
Enter the number of Years Owned.
Review Estimated Capacity (% of original), Range Lost in miles, and the Estimated Year when capacity hits 70% (common warranty threshold).

How the result changes with Full Charge Cycles

Full Charge Cycles: Approximate full charge cycles (full discharge + recharge = 1 cycle).
Average Climate Temp: Average annual temperature where the car is kept. Heat accelerates degradation.
Years Owned: How long you've owned the vehicle.
Charging Habit: Frequent DC fast charging accelerates degradation by ~30%.

Estimated Capacity: Current estimated battery capacity as a percentage of original.
Range Lost: Estimated miles of range lost from degradation (assuming 300mi initial).
Est. Replacement Year: Estimated year when capacity drops to 70% (common warranty threshold).
