How it is calculated
- Fuel per month = monthly km × L/100 km ÷ 100 × price per litre
- Road tax, insurance and servicing = yearly amount ÷ 12
- Monthly total = instalment + fuel + road tax + insurance + servicing + parking + tolls + other
- Cost per km = monthly total ÷ monthly km
Work out your road tax with the road tax calculator and your instalment with the car loan calculator.
Worked example
Instalment RM800, 1,500 km a month at 7 L/100 km and RM1.99 a litre, road tax RM90, insurance RM1,200 and servicing RM1,200 a year, parking RM150 and tolls RM100 a month:
- Fuel: 1,500 × 7 ÷ 100 × 1.99 = RM208.95
- Road tax: 90 ÷ 12 = RM7.50; insurance: 1,200 ÷ 12 = RM100; servicing: RM100
- Total: 800 + 208.95 + 7.50 + 100 + 100 + 150 + 100 = RM1,466.45 a month
- Cost per km: 1,466.45 ÷ 1,500 = RM0.98
Why your number may differ
This is a planning estimate from your own figures. Fuel prices change weekly, and insurance and servicing vary by car and workshop. Depreciation and unexpected repairs are not included unless you enter them.
