Fuel Range Calculator
Estimate vehicle driving range from tank size, current fuel level, reserve fuel, and fuel efficiency.
Formula
Fuel range formula
Actual range depends on traffic, terrain, load, air conditioning, weather, tire pressure, and driving style.
Range = usable fuel / efficiency x 100
A 50 L tank at 60% with 5 L reserve and 7 L/100 km gives about 357 km usable range.
FAQs
What is reserve fuel?+
Reserve fuel is the amount you do not want to plan on using, so it is subtracted from available fuel.
What efficiency unit does this use?+
It uses liters per 100 kilometers. Lower values mean better fuel efficiency.
How does the Fuel Range Calculator calculate the result?+
It uses the Fuel range formula: Range = usable fuel / efficiency x 100. A 50 L tank at 60% with 5 L reserve and 7 L/100 km gives about 357 km usable range.
What information do I need to use the Fuel Range Calculator?+
Estimate vehicle driving range from tank size, current fuel level, reserve fuel, and fuel efficiency.
How accurate is the Fuel Range Calculator?+
Fuel Range Calculator applies the formula and assumptions shown on this page. Results may be rounded for readability, so verify changing rates, thresholds, medical guidance, or legal rules with the cited source or a qualified professional.
What should I check before using the Fuel Range Calculator result?+
Check that the units, dates, rates, and assumptions match your situation. Change one input at a time to understand which values have the largest effect on the result.
