Frequently Asked Questions
How do I calculate fuel cost for a trip?

Multiply distance by fuel consumption rate, then multiply by price per litre. Formula: Cost = (Distance / 100) × L/100km × Price per litre. This calculator does it automatically.

How much does it cost to drive 500 km?

At 8 L/100km and $1.50/litre: 500 / 100 × 8 × $1.50 = $60 for a 500 km trip.

How do I convert L/100km to MPG?

To convert L/100km to US MPG: divide 235.214 by your L/100km figure. For example: 8 L/100km = 235.214 / 8 = 29.4 MPG.

What is average fuel consumption?

Average passenger car fuel consumption is 6-10 L/100km (28-47 MPG). SUVs and trucks typically use 10-15 L/100km. Hybrids use 4-6 L/100km.

How do I calculate my car fuel cost per month?

Calculate your monthly driving distance, use this tool to find the fuel cost, then multiply by 4 (weeks/month) or by monthly km directly.

How much does a road trip cost in fuel?

Enter your total trip distance, your car's fuel efficiency, and the current fuel price. This tool shows the exact one-way and round-trip fuel cost.

How do I reduce my fuel cost?

Drive at steady speeds, maintain proper tyre pressure, reduce idling, plan routes to avoid traffic, and keep up with vehicle maintenance. Each 10 km/h over 90 km/h increases fuel use by approximately 10%.
