How this calculation works
Fuel costs equal distance ÷ 100 × consumption × actual pump price. Add finance, insurance, maintenance, parking and one twelfth of annual fixed costs.
A worked example
1 000 km at 8 L/100 km and R30/L costs R2 400 in fuel each month, before finance and other running costs.
Assumptions & limitations
- This is a cash-flow budget, not the economic cost of ownership. Depreciation is excluded to avoid counting it on top of full loan principal repayments. Enter your actual local pump price; R30.24 is a dated inland 95 petrol example effective 4 November 2026.
