Mileage comparison
How annual mileage changes the estimate
The price, resale value and fixed costs stay unchanged. Only annual mileage and energy use change in this quick comparison.
AutoPrisme method
A complete economic cost, not only fuel
The calculator combines estimated value loss, petrol or electricity, insurance, parking and yearly allowances for servicing, repairs, tyres and road tax. Irregular bills are divided by twelve to make them comparable.
Formuladepreciation + energy + insurance + servicing + repairs + tyres + tax
Finance capital is not added on top of depreciation, which would count the car's value twice. Use the separate loan or PCP/HP calculator to examine interest and monthly cash flow.

Tesla Model 3 running costs
How much does a Tesla Model 3 cost per month?
There is no single monthly figure. The result depends on the price paid, future resale value, mileage, insurance and maintenance. Change every input to match the exact vehicle and your circumstances.
What efficiency should I use for a Model 3?
The pre-filled figure is tied to the Rear-Wheel Drive example and is only a starting point. Replace it with the official figure for your version or your own measured consumption.
Does the calculation include car finance?
No. This model page uses depreciation to represent the vehicle's economic cost and avoids adding the financed capital twice. Use the separate loan, PCP or HP tools to examine cash flow and interest.
