EV Charging Cost Estimator

Estimate the daily, monthly, and annual cost to charge an electric vehicle (Tesla, Rivian, Bolt, Ioniq, etc.) from miles driven, vehicle efficiency, electricity rate, and home-charger losses.

Miles Driven per Day

Vehicle Efficiency (mi/kWh)

Electricity Rate ($/kWh)

Charging Loss (%)

Limitations: Does not account for time-of-use (TOU) pricing, demand charges, public DC fast-charger pricing ($0.30–$0.60/kWh is common), battery degradation, cold-weather range loss, highway vs city efficiency, or grid losses upstream of your meter.

What to do next: Mi/kWh varies: Model 3 RWD ≈ 4.0–4.3, Model Y AWD ≈ 3.2–3.6, Mach-E AWD ≈ 2.7–3.1, Rivian R1S ≈ 2.0–2.3. For TOU plans, use your overnight rate. AC Level 2 home charging typically loses 8–12% between wall and battery; DC fast charging loses 10–15%.

Planning estimate only. Your utility bill is the source of truth — log a week of charging and compare.
