Calculating your estimated range is straightforward once you know the EV Range formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the EV Range Calculator.
What is EV Range?
The EV Range calculation tells you your estimated range from a few simple inputs. The figure you are solving for here is the estimated range.
The EV Range formula
The core formula is:
Estimated range = Battery capacity ÷ Energy consumption × 100Here is what each input means:
- Battery capacity — a value measured in kWh. Example: 60 kWh.
- Energy consumption — a value measured in kWh/100km. Example: 16 kWh/100km.
How to calculate it step by step
- Write down the battery capacity (for example, 60 kWh).
- Write down the energy consumption (for example, 16 kWh/100km).
- Apply the formula above to get your estimated range.
- Double-check the result with the EV Range Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Battery capacity | 60 kWh |
| Energy consumption | 16 kWh/100km |
| Estimated range | 375 |
With battery capacity of 60 kWh and energy consumption of 16 kWh/100km, the estimated range works out to 375.
Example 2
With battery capacity of 120 kWh and energy consumption of 16 kWh/100km, the estimated range works out to 750.
| Result | Value |
|---|---|
| Estimated range | 750 |
Example 3
With battery capacity of 30 kWh and energy consumption of 16 kWh/100km, the estimated range works out to 188.
| Result | Value |
|---|---|
| Estimated range | 188 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
