Official figures — September 2026. These are the confirmed prices published by the Department of Mineral and Petroleum Resources (DMPR), effective Wednesday, 2 September 2026. Petrol 93 and 95 both rose 134 c/l, diesel 500ppm rose 294 c/l, diesel 50ppm rose 315 c/l and illuminating paraffin rose 213 c/l. The previous official prices took effect on 5 August 2026.
When planning a road trip, daily commute, or logistics schedule across South Africa, transforming a per-litre petrol or diesel price into an actual out-of-pocket cost is essential. This interactive Trip Fuel Cost Calculator helps you quickly convert the latest official regulated fuel rates into realistic trip expenditure estimates.
Trip Fuel Cost Calculator Tool

Enter your distance, consumption and fuel price
To get an accurate estimate of your road expenses, you need to provide three core variables into the interactive tool:
Inputs needed
- Total Distance (km): The complete round-trip or one-way distance of your journey.
- Fuel Consumption Rate (L/100 km): The average efficiency of your vehicle. If you do not know your exact figure, look at your vehicle’s dashboard display or consult the manufacturer’s manual.
- Fuel Price per Litre (R/l or c/l): The local cost per litre of fuel at the pump. You can utilize our built-in default benchmarks or manually type in a specific station price.
Current fuel-price assumptions
Fuel prices in South Africa are heavily dependent on geographic zones due to the costs associated with transporting fuel from coastal ports to interior pipelines. For your convenience, the interactive calculator utilizes the official July 2026regulated fuel price schedule as its baseline assumption.
Current Official Prices (Effective 2 September 2026)
The following baseline metrics are sourced directly from the Department of Mineral and Petroleum Resources (DMPR):
| Fuel Grade & Pricing Zone | Official Price (Per Litre) | Pricing Structure Metric |
| Petrol 95 ULP (Inland) | R26.92 / L | 2,692.00 c/l |
| Petrol 93 ULP (Inland) | R26.76 / L | 2,676.00 c/l |
| Diesel 0.05% Sulphur (Inland Wholesale) | R29.11 / L | 2,911.11 c/l |
| Petrol 95 ULP (Coastal) | R26.05 / L | 2,605.00 c/l |
| Petrol 93 ULP (Coastal) | R25.97 / L | 2,597.00 c/l |
| Diesel 0.05% Sulphur (Coastal Wholesale) | R28.24 / L | 2,823.91 c/l |
Worked example
Let’s contextualize this for a typical long-distance South African drive: a family road trip from Johannesburg (Inland) to Durban (Coastal) using a standard family SUV.
Example calculation
- Route: Johannesburg to Durban (One-Way)
- Distance: 600 kilometers
- Vehicle Fuel Consumption: 8.0 Litres per 100 kilometers ($8.0\text{ L/100 km}$)
- Fuel Selection: Inland Petrol 95 ULP at the baseline rate of R26.92 per litre.
By running these variables through the script, the tool determines that the vehicle will use exactly 48 litres of fuel. At the regulated pump rate, the total calculated fuel cost for this single leg of the trip is exactly R1,252.80.
How the calculation works
The engine behind our calculator applies standard volumetric and price formulas to determine your exact fuel requirements.
Formula used
First, the total volume of fuel needed for the trip is isolated by scaling the vehicle’s standard $100\text{ km}$ baseline consumption up to your specific target distance:
$$\text{Fuel Volume (Litres)} = \left( \frac{\text{Distance (km)}}{100} \right) \times \text{Consumption Rate (L/100 km)}$$
Once the exact volume in litres is established, the total financial cost is produced by multiplying that quantity by the prevailing price per litre:
$$\text{Total Trip Cost (ZAR)} = \text{Fuel Volume (Litres)} \times \text{Fuel Price (R/L)}$$

Frequently asked questions
What inputs does the trip fuel cost calculator need?
To deliver an accurate financial projection, the calculator asks for your total route distance in kilometers, your vehicle’s specific fuel consumption index (measured in L/100 km), and the current retail fuel price in R/l or c/l. Optional inputs allow you to scale this into monthly commuting totals or ongoing multi-stop itineraries.
Are calculator results exact?
No. The outputs are mathematical estimations based purely on the variables you input. Real-world conditions—such as heavy stop-and-go traffic on the N1, aggressive acceleration, driving up steep mountain passes like Van Reenen’s Pass, or travelling with heavily loaded roof racks—will increase your actual consumption above the vehicle’s rated factory baseline.
Should inland and coastal prices be included?
Yes. South Africa enforces localized zonal pricing strategies because of transport infrastructure costs. Because inland fuel rates are consistently higher than coastal pump rates, the tool provides distinct location profile toggles to ensure your starting conditions mirror real provincial differences.
How can users reduce fuel costs?
Drivers can actively lower their fuel expenditure by maintaining optimal tyre pressure, removing excess vehicle weight, avoiding sudden acceleration, and planning routes efficiently. Additionally, referencing real-time fuel forecasting indices helps you decide whether to fill up your tank before or after the first Wednesday of an upcoming month.
