About the Annual Car Fuel Cost Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Miles per year = miles per week x 52 weeks
Gallons per year = miles per year / MPG
Annual fuel cost = gallons x gas price
Monthly cost = annual cost / 12
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: Miles per year = miles per week x 52 weeks Gallons per year = miles per year / MPG Annual fuel cost = gallons x gas price Monthly cost = annual cost / 12 Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Average commuter: 280 mi/week, 28 MPG, $3.50/gal
Inputs
With Miles Driven per Week = 280, Fuel Economy = 28 and Gas Price = 3.5 as the stated inputs, the result is Miles per Year = 14,560 miles, Gallons per Year = 520 gal and Monthly Fuel Cost = $152/mo. Each value corresponds to the declared output fields.
Example 2: Long-haul commuter: 500 mi/week, 20 MPG, $3.60/gal
Inputs
With Miles Driven per Week = 500, Fuel Economy = 20 and Gas Price = 3.6 as the stated inputs, the result is Miles per Year = 26,000 miles, Gallons per Year = 1,300 gal and Monthly Fuel Cost = $390/mo. Each value corresponds to the declared output fields.
Example 3: Rideshare driver: 1,200 mi/week, 35 MPG sedan, $3.40/gal
Inputs
With Miles Driven per Week = 1,200, Fuel Economy = 35 and Gas Price = 3.4 as the stated inputs, the result is Miles per Year = 62,400 miles, Gallons per Year = 1,782.9 gal and Monthly Fuel Cost = $505/mo. Each value corresponds to the declared output fields.
Example 4: Retired couple: 150 mi/week, 36 MPG Civic, $3.25/gal
Inputs
With Miles Driven per Week = 150, Fuel Economy = 36 and Gas Price = 3.25 as the stated inputs, the result is Miles per Year = 7,800 miles, Gallons per Year = 216.7 gal and Monthly Fuel Cost = $59/mo. Each value corresponds to the declared output fields.
