Specialized Fuel Cost Calculators

RV Fuel Cost Calculator

Planning an RV trip? Calculate your motorhome's fuel expenses accurately based on its typically lower fuel efficiency. Our RV fuel cost calculator helps you budget for cross-country adventures or weekend getaways.

  • Average Class A motorhome: 6-10 MPG
  • Average Class C motorhome: 8-12 MPG
  • Average Class B campervan: 14-18 MPG
  • Fifth wheels and travel trailers reduce towing vehicle MPG by 30-50%

Boat Fuel Cost Calculator

Marine fuel costs can be significant due to lower efficiency and higher fuel prices at marinas. Our boat fuel cost calculator helps you estimate expenses for your next boating trip or yacht journey.

  • Small outboard boats (50-90 HP): 2-4 MPG
  • Medium cabin cruisers: 1-2 MPG
  • Large motor yachts: 0.5-1 MPG
  • Remember that boat fuel consumption varies significantly with speed

Semi Truck Fuel Cost Calculator

For trucking companies and owner-operators, fuel represents 30-40% of operating costs. Our semi truck fuel cost calculator helps optimize routes and estimate expenses accurately.

  • Average semi truck: 5.5-8.5 MPG
  • Loaded trucks typically get 30% lower MPG than empty ones
  • Newer trucks with aerodynamic features can achieve better efficiency
  • Idling can consume 0.5-1.0 gallon per hour

Private Jet Fuel Cost Calculator

Private aviation fuel costs are a major expense factor. Our private jet fuel cost calculator helps estimate operating expenses for different aircraft types and journey lengths.

  • Light jets (e.g., Citation CJ3): 150-200 gallons per hour
  • Midsize jets (e.g., Citation XLS): 210-280 gallons per hour
  • Heavy jets (e.g., Gulfstream G650): 350-500 gallons per hour
  • Jet fuel (Jet A) typically costs more than automotive fuels

Car Fuel Cost Calculator

Calculate fuel expenses for daily commutes, road trips, or annual budgeting. Our calculator helps you compare vehicles and understand the real cost of driving.

  • Average sedan: 25-30 MPG
  • Average SUV: 15-20 MPG
  • Hybrid vehicles: 40-55 MPG
  • Electric vehicles: Equivalent of 100-140 MPGe

How to Calculate Cost Per Mile for Fuel

Understanding your cost per mile helps with budgeting and comparing vehicle expenses:

  1. Determine your vehicle's MPG (check your owner's manual or use actual driving data)
  2. Note the current fuel price per gallon in your area
  3. Divide the fuel price by your MPG to get your cost per mile
  4. Formula: Cost per mile = Fuel price per gallon ÷ Miles per gallon
  5. Example: $3.50 per gallon ÷ 25 MPG = $0.14 per mile

Fuel Cost Comparison for Different Vehicles

Vehicle Type Average MPG Fuel Cost per 100 Miles* Annual Fuel Cost**
Compact Car 30-35 MPG $10.00-$11.67 $1,200-$1,400
Midsize Sedan 25-30 MPG $11.67-$14.00 $1,400-$1,680
SUV 15-20 MPG $17.50-$23.33 $2,100-$2,800
Pickup Truck 12-18 MPG $19.44-$29.17 $2,333-$3,500

Frequently Asked Questions

How do I calculate fuel cost for a boat trip?

To calculate boat fuel costs, you'll need your boat's fuel consumption rate (typically in GPH - gallons per hour), estimated trip duration, and current marine fuel prices. Our boat fuel cost calculator can help by converting these factors into a total cost estimate.

What is the average fuel efficiency for an RV?

RV fuel efficiency varies by class: Class A motorhomes average 6-10 MPG, Class C motorhomes average 8-12 MPG, and Class B campervans average 14-18 MPG. Travel trailers and fifth wheels reduce the towing vehicle's MPG by 30-50%.

How much does it cost to fuel a semi truck?

Semi trucks typically get 5.5-8.5 MPG and have 120-300 gallon fuel tanks. At current diesel prices (approximately $4.50/gallon), filling a 200-gallon tank costs around $900. For a typical 1,000-mile haul, fuel costs range from $530-$820.

How much does private jet fuel cost?

Private jet fuel costs depend on the aircraft size. Light jets consume 150-200 gallons per hour, midsize jets use 210-280 gallons per hour, and heavy jets burn 350-500 gallons per hour. With Jet A fuel at $5-7 per gallon, hourly fuel costs range from $750 for small jets to $3,500 for large jets.

How can I improve my vehicle's fuel efficiency?

Improve fuel efficiency by maintaining proper tire pressure, removing excess weight, using cruise control on highways, avoiding aggressive acceleration and braking, keeping up with regular maintenance, and reducing idling time.

How does speed affect fuel consumption?

Most vehicles achieve optimal fuel efficiency between 50-60 mph. Fuel economy typically decreases rapidly above 60 mph due to increased aerodynamic drag. Driving 75 mph instead of 65 mph can reduce fuel economy by 10-15%.

How do I convert between different fuel efficiency units?

To convert MPG to L/100km, divide 235.2 by the MPG value. To convert L/100km to MPG, divide 235.2 by the L/100km value. To convert MPG to km/L, multiply MPG by 0.425.

Note: This calculator provides estimates based on consistent fuel efficiency. Actual consumption may vary based on driving conditions, vehicle load, weather, and driving style. For most accurate results, use your vehicle's actual average fuel efficiency from past trips.
