Fuel Use Trip Calculator Formula and Mathematical Explanation

The Fuel Use Trip Calculator employs straightforward mathematical formulas to provide accurate estimates. Understanding these formulas helps users appreciate the logic behind the calculations and interpret the results effectively.

Step-by-Step Derivation

1. Calculate Total Fuel Needed: The first step is to determine how many liters of fuel your vehicle will consume over the entire trip. Fuel efficiency is typically given in Liters per 100 kilometers (L/100km). To find the total fuel, we divide the total trip distance by 100 (to get the number of 100km segments) and then multiply by the vehicle’s fuel efficiency.
   
   Total Fuel Needed (L) = (Trip Distance (km) / 100) × Fuel Efficiency (L/100km)
2. Calculate Total Trip Fuel Cost: Once the total fuel needed is known, we multiply it by the average fuel price per liter to get the total monetary cost for the trip.
   
   Total Trip Fuel Cost ($) = Total Fuel Needed (L) × Average Fuel Price ($/Liter)
3. Calculate Cost per 100 km: This intermediate value helps understand the running cost for a standard distance. It’s simply the fuel efficiency multiplied by the fuel price.
   
   Cost per 100 km ($) = Fuel Efficiency (L/100km) × Average Fuel Price ($/Liter)
4. Calculate Cost per Passenger: If the trip cost is to be shared, dividing the total fuel cost by the number of passengers provides the individual contribution.
   
   Cost per Passenger ($) = Total Trip Fuel Cost ($) / Number of Passengers

  • Total Trip Fuel Cost = 26.25 × $1.95 = $51.19
  • Cost per 100 km = 7.5 × $1.95 = $14.63
  • Cost per Passenger = $51.19 / 2 = $25.60
• Output: Sarah and her friend can expect to pay approximately $51.19 for fuel, or $25.60 each. This helps them budget for other trip expenses.

Example 2: Business Delivery Route

A small business uses a delivery van for a daily route covering 120 km. The van’s fuel efficiency is 12.0 L/100km, and the business tracks fuel at an average of $1.70/Liter. Only the driver is in the vehicle.

• Inputs:
  • Trip Distance: 120 km
  • Fuel Efficiency: 12.0 L/100km
  • Average Fuel Price: $1.70/Liter
  • Number of Passengers: 1
• Calculations:
  • Total Fuel Needed = (120 / 100) × 12.0 = 1.2 × 12.0 = 14.4 Liters
  • Total Trip Fuel Cost = 14.4 × $1.70 = $24.48
  • Cost per 100 km = 12.0 × $1.70 = $20.40
  • Cost per Passenger = $24.48 / 1 = $24.48
• Output: The business can expect to spend $24.48 on fuel for this daily route. Over a month (20 working days), this amounts to $489.60, crucial information for operational budgeting and pricing delivery services. This also highlights the importance of a vehicle running costs analysis.
