- 2 Enter vehicle fuel consumption (L/100km) and current fuel pump price per litre in Rand.
- 3 Optionally include highway toll plaza fees.
- 4 Specify the number of passengers sharing the journey to calculate cost per person.
Questions
Why are petrol prices different inland versus coastal in South Africa?
Inland petrol prices in South Africa are slightly higher than coastal prices because they include the pipeline transport cost from coastal refineries and Durban harbour to Gauteng and the interior.
How do I calculate road trip fuel cost in South Africa?
Multiply distance in km by (L/100km ÷ 100) to find litres needed, then multiply by the petrol/diesel price per litre and add highway toll plaza fees.
