- Annual Fuel Consumption = 10,000 miles / 35 MPG = 285.71 gallons
- Total Annual Fuel Cost = 285.71 gallons * $3.80/gallon = $1,085.70
- Cost Per Mile = $1,085.70 / 10,000 miles = $0.1086 per mile (approx. 11 cents)
Interpretation: Sarah can expect to spend around $1,086 annually on fuel for her commute. This translates to about 11 cents per mile, helping her budget effectively for transportation costs.
Example 2: SUV Owner in a Region with Higher Fuel Prices
Scenario: Mark owns an SUV that gets 20 MPG. He drives about 15,000 miles annually for a mix of commuting and family trips. Fuel prices in his area are higher, averaging $4.50 per gallon.
Inputs:
- Annual Driving Distance: 15,000 miles
- Vehicle Fuel Efficiency: 20 MPG
- Average Fuel Price: $4.50 per Gallon
Calculations:
- Annual Fuel Consumption = 15,000 miles / 20 MPG = 750 gallons
- Total Annual Fuel Cost = 750 gallons * $4.50/gallon = $3,375.00
- Cost Per Mile = $3,375.00 / 15,000 miles = $0.225 per mile (approx. 23 cents)
Interpretation: Mark's higher fuel consumption and the elevated fuel prices mean his annual fuel cost is significantly higher at $3,375. The cost per mile is also considerably greater at 23 cents. This might prompt him to consider more fuel-efficient driving habits or explore hybrid/electric vehicle options for his next purchase.
