2026 Tesla Model 3 Standard RWD (Rear-Wheel Drive)

$44.50 per month

Per mile: 4.4¢
Per 100 miles: $4.45
Annual: $533.99
Energy per month: 243 kWh
Gas car per month: $145.50
Gas cost minus EV cost: $101.00

EPA record 50251, retrieved 2026-09-27. Blended charging rate 18.3¢/kWh. Fees, membership charges and vehicle purchase/maintenance costs are excluded. Exact EPA vehicle record

Break-even blended electricity rate: 59.9¢/kWh, using your gasoline price and mpg. A negative monthly difference means this EV costs more for energy.

EPA laboratory ratings vary from real-world weather, speed and towing. Home share is a share of energy, not a share of sessions. No extra charging-loss multiplier is applied to EPA driving energy.
