Frequently Asked Questions
How does the fuel cost calculator work?
Enter your trip distance, vehicle fuel economy (MPG or L/100km), and fuel price. The calculator shows fuel needed, total cost, and cost per mile/km. Enable round trip for return journey costs or commute mode for recurring daily travel expenses.
How does commute mode calculate recurring costs?
Commute mode multiplies your one-way (or round trip) fuel cost by the number of commute days per week, then projects weekly, monthly, and annual totals. This helps you budget for ongoing transportation expenses and compare costs between vehicles.
What vehicle presets are available?
The calculator includes 8 vehicle presets: Compact Car, Sedan, SUV, Pickup Truck, Minivan, Sports Car, Hybrid, and Electric (equivalent). Each preset auto-fills typical fuel economy values in both MPG and L/100km.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
Does this account for city vs highway driving?
This calculator uses a single fuel economy value. For more accurate results, use your combined MPG rating or select the closest vehicle preset and adjust based on whether your driving is mostly city or highway.
