EV Battery Replacement Cost Calculator

Estimate the cost of replacing your EV battery pack. Most EV owners will never need to replace their battery, as modern batteries outlast the vehicle. However, it's useful to understand potential costs and plan accordingly.

Battery Degradation Reality:

• Modern EVs (2018+) degrade ~2-3% per year on average
• Most retain 80-90% capacity after 10 years
• Tesla Model S/X batteries average 90% capacity at 200,000 miles
• Warranties typically cover degradation below 70% (rarely triggered)

Cost Trends:

• 2010: $1,200/kWh
• 2015: $380/kWh
• 2020: $140/kWh
• 2024: $120-140/kWh
• 2030 target: $80/kWh or less

Recommendation: Don't worry excessively about battery replacement. The likelihood is low, warranties are comprehensive, and costs are declining rapidly. Focus on proper battery care instead.
