1. What is the Total Fuel Cost Formula?

The Total Fuel Cost formula calculates the combined fuel expenses for one or more vehicles based on distance traveled, fuel efficiency, and local fuel prices.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Distance}_i \) — Miles traveled by vehicle i
• \( \text{Efficiency}_i \) — Fuel efficiency in miles per gallon (mpg) for vehicle i
• \( \text{Price}_i \) — Fuel price in dollars per gallon ($/gallon) for vehicle i

Explanation: The formula calculates gallons used for each vehicle (distance/efficiency) and multiplies by local fuel price, then sums all vehicle costs.

3. Importance of Fuel Cost Calculation

Details: Accurate fuel cost estimation helps with budgeting for trips, comparing vehicle operating costs, and making informed transportation decisions.

4. Using the Calculator

Tips: Enter distance in miles, efficiency in mpg, and price per gallon in dollars. You can calculate for one vehicle or compare costs for two vehicles.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate, but actual costs may vary based on driving conditions, vehicle load, and fuel quality.

Q2: What if my vehicle uses liters per 100 km?
A: First convert to mpg: mpg = 235.214583 / (L/100km)

Q3: Should I include city and highway mpg separately?
A: For most accurate results, use the mpg that matches your driving conditions or calculate separate legs of your trip.

Q4: How does speed affect fuel efficiency?
A: Most vehicles have optimal efficiency between 45-60 mph. Efficiency typically decreases significantly above 70 mph.

Q5: Can I calculate for more than two vehicles?
A: For multiple vehicles, you can perform multiple calculations and sum the results.
