Tesla Charging Cost Calculator

Calculate your Tesla charging costs at home vs Supercharger. Covers every model 2018-2026 with real efficiency data and current US electricity rates.

Tesla Model & Battery

Select your Tesla model and set your annual driving habits

Tesla ModelSelect your Tesla model to use its real-world energy efficiency (Wh/mi) and battery capacity for accurate cost calculations.

Annual MileageYour total estimated driving distance per year. The average American drives about 13,500 miles per year.

mi/year

Home Charging PercentageThe percentage of charging you do at home. Most Tesla owners charge at home 80-90% of the time. Home charging is significantly cheaper than Superchargers.

Electricity Rates

Configure your home and Supercharger electricity costs

Home Electricity RateYour residential electricity rate per kWh. Check your utility bill for the exact rate. US average is ~$0.16/kWh but varies widely by state.

$/kWh

Supercharger Off-Peak RateTesla Supercharger rate during off-peak hours (typically 9 PM - 11 AM). Rates vary by location and time of day.

$/kWh

Supercharger On-Peak RateTesla Supercharger rate during peak hours (typically 11 AM - 9 PM). Peak rates can be 30-50% higher than off-peak.

$/kWh

Charging Efficiency at HomeHow efficiently your home charger converts grid electricity to battery charge. Level 2 chargers typically achieve 85-90% efficiency due to heat loss during charging.

Charging Efficiency at SuperchargerSuperchargers are typically more efficient (90-95%) than home Level 2 chargers due to direct DC charging and advanced thermal management.

Gas Comparison (optional)

Compare Tesla charging costs against a gasoline vehicle

Gas Car MPGThe fuel efficiency of the gas car you're comparing against. The average new car gets about 25-30 MPG combined.
