Electric Car Range Calculator

Plan your driving range around usable energy, realistic consumption and an arrival reserve.

Your vehicle, your numbers

Example numbers are prefilled. Replace them with your vehicle data and local prices. Currency changes the label, not the exchange rate.

Where do I find this?

Use the exact model and market in the vehicle documents. A matching name alone does not verify battery specifications.

kWh
An original specification preset must be replaced with current usable capacity where known.
Where do I find this?

Match usable/net capacity to the exact pack and configuration. Check whether this field asks for original or current capacity; gross capacity is different.

See the explanation →
kWh/100 km
Use battery-side driving consumption, not energy from your electricity bill.
Where do I find this?

Find recent driving consumption in the vehicle’s trip or energy display. Record the period and units. A charger receipt includes losses.

%
Where do I find this?

Read the battery charge percentage at the start of the scenario. This is state of charge, not state of health.

Where do I find this?

Choose the charge you want left on arrival. It must not exceed the starting charge.

°C
Where do I find this?

Use the expected outside temperature. It records context; it does not automatically set a range penalty.

Where do I find this?

Choose the description that matches this scenario. Review the explanation to see which settings affect arithmetic and which record context.

%
Add a percentage if the entered consumption does not already reflect your trip. Temperature and profile are context, not automatic penalties.
Where do I find this?

Enter a chosen consumption increase only if the baseline does not already include the harder conditions.

±10% is an illustrative sensitivity band, not a statistical confidence interval.
Where do I find this?

Choose an input-sensitivity assumption. A larger number widens the scenario; it is not a measured confidence interval.

Your results

Transparent by design

A clearer picture starts here.

Review the example inputs, then calculate. We show the assumptions alongside your result.

Why is this an estimate?

Avoid double-counting cold or motorway use if these are already included in your consumption. Practical bands reflect your input sensitivity.

Read our methodology

EVVerity estimates are informational and are not a substitute for a professional battery diagnostic or pre-purchase vehicle inspection.

See how the calculation works

Range = usable capacity × available charge fraction ÷ consumption × 100. Scenario consumption = entered consumption × (1 + adjustment ÷ 100).

Avoid double-counting cold or motorway use if these are already included in your consumption. Practical bands reflect your input sensitivity.

Example: allow energy for your arrival reserve

With 60 kWh currently usable, 80% starting charge and a 10% arrival reserve, the planning window contains 42 kWh. At 16.5 kWh/100 km, the central trip estimate is about 255 km. The full-charge theoretical figure is different because it uses the whole usable capacity.

Where to get useful inputs

  • Use current usable capacity, if known. A new-car specification may overstate the energy now available.
  • Choose consumption that resembles the intended route. A profile label by itself does not change the calculation.
  • Enter a consumption increase to explore different conditions; temperature is context, not an automatic forecast.
Does the result promise I will reach the destination?

No. Wind, weather, speed, detours and vehicle conditions can differ from your inputs. Keep an appropriate reserve and use the vehicle’s own trip and charging guidance.

Methodology, assumptions & confidence →

Test a 180 km round trip

Original EVVerity worked scenario. Inputs are illustrative, not measured vehicle results or market prices.

  1. Use current usable capacity 54 kWh, start 80%, reserve 10%, consumption 18 kWh/100 km and additional consumption increase 0. The central range is 210 km.
  2. Change consumption to 23 with the other inputs unchanged: range falls to about 164 km, below the proposed round trip.
  3. The 180 km route at 23 kWh/100 km needs 41.4 kWh. With a 10% arrival reserve, departure charge must be about 86.7% in this scenario.

What the result helps you decide

A route can fit one consumption assumption and fail another. Enter observed consumption appropriate to the trip, check the vehicle’s route guidance and keep a workable charging alternative.

Example checked .

How far can an EV drive from 80% to 20%?

That window uses 60% of usable battery energy. For an illustrative 60 kWh pack at 18 kWh/100 km, 36 kWh supports 200 km before reaching the 20% reserve. At 24 kWh/100 km, the same energy supports 150 km. These are arithmetic scenarios, not tested range figures for a model.

Starting charge is what the car has now. Arrival reserve is what you want left when you stop. Enter 80 and 20 above for this example; do not subtract the reserve again after reading the result.

Which battery capacity and consumption should I use?

Use current usable capacity when you have credible evidence for it. Gross capacity and the usable capacity when new are different references. Choose consumption representative of the trip and on a compatible battery-energy basis. Unit conversion fixes the units, not an inconsistent measurement boundary.

Keep the chosen reserve within the starting charge. A zero usable charge window produces zero planned distance; it is not a fault in the calculator. The sensitivity band explores your input uncertainty and does not guarantee that a route or charger is reachable.
