Fuel Cost Calculator South Africa
Estimate fuel cost for one trip, a normal month and a full year using distance, fuel consumption and the price per litre.
Calculate your fuel budget
Use the return-trip distance and real average consumption for the most useful result.
How to compare fuel costs accurately
The same fuel price can produce very different budgets depending on distance and litres per 100 km.
Litres per 100 km
A lower L/100 km number means less fuel is used over the same distance.
Trip frequency
A small daily saving becomes meaningful when the journey is repeated many times each month.
City versus highway use
Stop-start traffic often increases consumption, while steady highway driving may reduce it.
Fuel-price sensitivity
Recalculate at a higher price per litre to understand how exposed your budget is to future fuel-price changes.
Build a realistic fuel budget
- Measure the return distance of the journey rather than one direction only.
- Use your real average L/100 km from the trip computer or fuel receipts when available.
- Enter the expected number of trips in a normal month.
- Add a safety margin for congestion, detours and occasional longer journeys.

Fuel cost questions
How is trip fuel cost calculated?
Distance is multiplied by litres per 100 km, divided by 100, and then multiplied by the fuel price per litre.
Is a lower L/100 km figure better?
Yes. It means the vehicle uses fewer litres to travel 100 kilometres under the measured conditions.
Why is my real consumption higher than advertised?
Official tests use controlled conditions. Traffic, short trips, vehicle load, tyres, weather and driving style can increase real consumption.
Does the calculator work for diesel?
Yes. Enter the diesel price per litre and the vehicle's diesel consumption figure.
