What is Fuel Cost Calculator?

The Fuel Cost Calculator is a comprehensive tool for calculating fuel-related expenses and efficiency metrics. It helps you estimate trip costs, determine fuel efficiency (MPG or L/100km), calculate distances, and convert between different units. This calculator is essential for trip planning, budgeting, and understanding your vehicle's fuel economy.

How to Use This Calculator

  1. Select a calculation type from the dropdown (Total Cost, Cost Per Distance, Fuel Efficiency, Distance, Fuel Needed, or Unit Conversions).
  2. Enter the required values in the input form.
  3. Select appropriate units for your inputs and desired result.
  4. Click 'Calculate' to see the results.
  5. Review the detailed results, visualizations, and step-by-step solution.

Calculation Types

Calculate Total Cost

Calculate the total fuel cost for a trip. Enter distance, fuel efficiency (MPG or L/100km), and fuel price. Formula: Cost = (Distance / Efficiency) × Price.

Calculate Cost Per Distance

Calculate fuel cost per mile or kilometer. Enter fuel efficiency and price. Formula: Cost per distance = Price / Efficiency.

Calculate Fuel Efficiency

Calculate fuel efficiency (MPG or L/100km) from distance traveled and fuel used. Formula: Efficiency = Distance / Fuel.

Calculate Distance

Calculate distance that can be traveled with a given amount of fuel and efficiency. Formula: Distance = Fuel × Efficiency.

Calculate Fuel Needed

Calculate fuel needed for a specific distance. Enter distance and fuel efficiency. Formula: Fuel = Distance / Efficiency.

Convert Units

Convert between distance units (miles/km) and fuel volume units (gallons/liters).

Fuel Efficiency Formulas

MPG (Miles Per Gallon):

MPG = Distance (miles) / Fuel (gallons)

L/100km (Liters Per 100 Kilometers):

L/100km = (Fuel (liters) / Distance (km)) × 100

Conversion:

  • MPG = 235.214 / (L/100km)
  • L/100km = 235.214 / MPG

MPG (Miles Per Gallon) is the US standard for measuring fuel efficiency, representing how many miles a vehicle can travel on one gallon of fuel. L/100km (Liters Per 100 Kilometers) is the metric standard, representing how many liters of fuel are needed to travel 100 kilometers. Lower L/100km values indicate better fuel efficiency.

Supported Units

  • per liter (USD per liter)

Typical Fuel Efficiency Values

Vehicle Type MPG L/100km Description
Hybrid Car45-603.9-5.2Excellent fuel economy
Economy Car30-405.9-7.8Good fuel economy
SUV/Truck15-259.4-15.7Moderate fuel economy
Sports Car15-259.4-15.7Lower fuel economy

Important Notes

  • All input values must be positive numbers (non-negative).
  • Fuel efficiency must be greater than zero for all calculations.
  • Distance and fuel used must be greater than zero when used in efficiency calculations.
  • The calculator automatically handles unit conversions between imperial and metric systems.
  • MPG and L/100km are inversely related - higher MPG means lower L/100km.
  • Fuel prices can vary significantly by location and time.
  • Actual fuel efficiency may vary based on driving conditions, vehicle maintenance, and driving habits.
  • Results are displayed with step-by-step solutions showing the calculation process.

Common Applications

  • Trip planning and budget estimation
  • Comparing fuel costs between different vehicles
  • Tracking fuel efficiency over time
  • Determining fuel needed for long-distance travel
  • Calculating cost per mile for business expenses
  • Understanding vehicle fuel economy
  • Planning fuel stops for road trips
