How do I calculate EV range while keeping an arrival reserve?
A theoretical full-battery range is different from the distance available between your starting charge and a chosen reserve. Here is an explicit planning example.

A closer look
Calculate the usable interval
With an illustrative 60 kWh usable battery, an 80% start and a 15% reserve leave 65% of capacity for the trip: 39 kWh. At an assumed 18 kWh/100 km, that corresponds to about 217 km. None of those assumptions is a promise for a particular car.
Change the consumption assumption
At 22 kWh/100 km, the same 39 kWh covers about 177 km. That difference is why a realistic consumption range matters. Use conditions comparable to the planned journey and keep charging alternatives within the less optimistic scenario.
Do not count the reserve twice
If you have already subtracted the reserve when calculating available energy, avoid subtracting the same percentage again from the result. Keep a separate allowance for uncertainty if desired and label it explicitly so the plan is understandable.
