Estimating the cost of fuel for your journeys is essential for budgeting and making informed decisions about travel. This calculator helps you quickly determine the anticipated fuel expense for any given trip, based on your car's fuel efficiency and the current price of fuel.
How the Calculation Works
The calculation is straightforward and relies on three key inputs:
Distance Travelled: The total length of your journey in kilometers (km).
Fuel Efficiency: How many kilometers your vehicle can travel on one liter of fuel (km/L). This is a crucial metric for understanding your car's economy.
Fuel Price: The cost of one liter of fuel in your local currency.
2. Calculate Total Cost: Total Fuel Cost = Fuel Needed (L) * Fuel Price (per Litre)
By inputting these values into our calculator, you get an immediate estimate of the fuel expense for your trip.
Use Cases for the Fuel Cost Calculator
Trip Planning: Estimate the fuel cost for road trips, daily commutes, or business travel to budget effectively.
Vehicle Comparison: If you're considering purchasing a new car, you can compare the estimated fuel costs of different models based on their stated fuel efficiency.
Cost Management: For businesses or individuals managing fleets, this tool helps in tracking and controlling fuel expenditures.
Understanding Efficiency: By using the calculator with known distances and actual fuel consumption, you can verify or understand your car's real-world fuel efficiency.
Example Calculation
Let's say you are planning a road trip of 800 km. Your car has a fuel efficiency of 12 km/L, and the current fuel price is $1.90 per liter.
1. Fuel Needed: 800 km / 12 km/L = 66.67 liters
2. Total Fuel Cost: 66.67 L * $1.90/L = $126.67
This means your estimated fuel cost for this trip would be approximately $126.67.

var fuelPrice = parseFloat(document.getElementById("fuelPrice").value);
var resultElement = document.getElementById("result");
// Clear previous result if any input is invalid

resultElement.innerHTML = "Please enter valid numbers.";
return;
}
if (distance <= 0 || fuelEfficiency <= 0 || fuelPrice < 0) {
resultElement.innerHTML = "Inputs must be positive (except price which can be 0).";
return;
}
var fuelNeeded = distance / fuelEfficiency;
var totalCost = fuelNeeded * fuelPrice;
// Format the output to two decimal places for currency
resultElement.innerHTML = "$" + totalCost.toFixed(2);
