How to Use the Cost of Petrol Calculator
This calculator estimates the total cost of petrol for a trip based on distance, fuel efficiency, and petrol price. All values must be in metric units (kilometers and liters).
- Enter Distance (km): Input the total trip distance in kilometers (e.g., 500). Must be greater than 0.
- Enter Fuel Efficiency (km/L): Input your vehicle's fuel consumption rate in kilometers per liter (e.g., 15). Must be at least 0.1.
- Enter Petrol Price ($/L): Input the price per liter of petrol in dollars (e.g., 1.50). Can be 0 or more.
- Click "Calculate": Press the button to compute the result.
Output: The total cost is displayed in dollars ($), along with the fuel needed in liters (L). The formula used is: (Distance ÷ Efficiency) × Price.
Tip: Ensure all inputs are positive numbers. Invalid entries will show error messages.

Frequently Asked Questions
The total cost is calculated as (Distance / Fuel Efficiency) × Price per Liter. For example, if you drive 500 km with an efficiency of 15 km/L and petrol costs $1.50/L, the cost is (500/15) × 1.50 = $50.00.
The calculator uses kilometers for distance, kilometers per liter (km/L) for fuel efficiency, and dollars per liter for price. You can convert other units before entering.
Yes, you can use it for diesel or any other fuel by entering the appropriate price and efficiency.
