I prefer to do this type of thing on actual usage - you never run a fuel tank dry (intentionally), so there is no point in calculating of tank capacities, etc.
So for petrol/diesel, start at the petrol station with an tank which is as "empty" as you would normally risk taking it. Reset the trip and fill it up. Keep the receipt in your glovebox, ashtray, etc.
Next time you are back to roughly the same "empty", clock the milage and write it on the receipt. Rinse and repeat a few times. Work out the average.
The last time I did this in my Golf GTD, it worked out at £67.45 / 437 = £0.154 / mile.
According to the calculator on the Tesla website, at £0.13 / kWh, 435 miles would cost £19.79 = £0.045 / mile.
A very rough estimate of the EV costing a little less than 1/3 the cost of ICE.
Obviously, Tesla are assuming some sort of normal driving style to get the estimated range from the charge. You'll only get a figure which is accurate for your driving style by actually measuring the kWh at its source and recording your mileage.
