How much battery does your Tesla really have left?

Pick your model, mileage, and age. We'll estimate remaining capacity and full-charge range, and show where you sit against typical numbers for the same cohort. Useful before buying used, before a long trip, or when the range estimate looks off.

Method: aggregated public Tesla degradation data (Recurrent, Tessie, Tesla Owners Online). This is an estimate, not a cell-level reading.
