Calculate your monthly car costs

How are your car costs calculated?

How is depreciation calculated?

The calculator spreads the difference between the purchase price and expected residual value evenly across the holding period. A lower residual value increases the monthly cost. Try several assumptions; the calculator does not predict a resale price.

Which running costs are included?

Annual tax and energy costs are divided by twelve. Enter insurance, maintenance, parking and interest costs as monthly amounts. For electricity, use kWh per 100 distance units and the price per kWh; for fuel, use litres and the price per litre. Keep consumption and annual mileage in the same distance unit.

Why not enter the full loan payment?

The purchase price is already reflected in depreciation. Enter only interest costs under finance costs, not the principal repayment. The model describes costs; actual payments from your account may differ.

What does tied-up capital mean?

The assumed annual return is applied to the average of purchase price and residual value, then divided by twelve. This is a simplified sensitivity for foregone returns, not an additional bill or a guaranteed return. Set it to 0% to see costs without this effect.
