Tesla EV Range Calculator: Find Your Real World Range

Verified baseline references

These are selected EPA records for model year 2026, using the EPA’s recorded names. Tesla’s sales labels and offered configurations can change. Match the exact model-year label on your vehicle; a rating in this table does not establish that the vehicle is currently on sale.

Tesla: rated miles and route predictions answer different questions

Tesla explains that the miles shown beside the battery icon use rated efficiency, rather than learning your personal driving pattern. The Energy app shows recent consumption and trip projections. A decrease in displayed miles alone therefore does not measure battery capacity loss. Tesla’s range guidance explains the distinction.

For a journey, compare this scenario with the navigation system’s predicted arrival charge. A route prediction can react to the actual route; this planner only scales the baseline you select. If the two differ, check speed, route, weather and accessory use before choosing the more optimistic number.

Make a useful owner record

Record distance driven and the starting and ending charge for several similar journeys. Exclude journeys where the car charged between readings. For example, driving 90 miles while charge falls from 80% to 45% gives 90 ÷ 0.35 ≈ 257 miles as a full-charge equivalent for those conditions. That is an example calculation, not a Tesla test result.

Keep parked energy use separate when comparing journeys: Sentry Mode and climate features can consume energy without adding miles. Follow the recommended daily charge limit displayed by your own vehicle; Tesla notes that different batteries have different charging routines. This planner’s 100% departure default displays the rated baseline and is not a daily charging recommendation.

Compare a charger leg with a reserve

With a 363-mile Model 3 Premium RWD baseline, an 80% departure and 10% reserve give 254.1 miles before adjustment. If your own comparable journeys support an 85% conditions factor, the scenario becomes 216.0 miles. Enter a 180-mile leg to see an estimated 21.7% arrival charge. The 85% is an illustrative assumption, not a Tesla winter coefficient.

Calculation method and owner calibration

Usable distance = baseline × conditions factor ÷ 100 × (starting charge − reserve) ÷ 100

Arrival charge = starting charge − leg distance ÷ (baseline × conditions factor ÷ 100) × 100

The method assumes distance scales approximately with the charge used. It does not model changing speed, wind, elevation, traffic, parked energy use, battery temperature or auxiliary loads. The conditions factor is an explicit assumption; no automatic age, temperature or equipment coefficient is applied.

To estimate an owner baseline, divide the distance of a representative journey by the fraction of charge used, with no recharge between readings. For example, 75 miles using 30 percentage points gives approximately 250 miles as a full-charge equivalent. Repeat with several comparable journeys. Use factor 100% when your measured baseline already describes the planned conditions, so the same effects are not counted twice.

A positive margin only means the arithmetic reaches your chosen reserve under these assumptions. A negative margin means the chosen distance exceeds that charge budget. Confirm route and charging conditions with the vehicle’s guidance; this tool does not diagnose the battery.
