How To Calculate Miles Per Gallon Cost

Calculating the cost of driving your vehicle is essential for budgeting and making informed decisions about your transportation expenses. One crucial metric to consider is Miles Per Gallon (MPG) cost. In this article, we’ll provide you with a handy calculator and guide you through the process of using it effectively to determine your vehicle’s cost per mile.


To calculate Miles Per Gallon (MPG) cost, you need two primary pieces of information:

  1. Miles Driven (miles): The total number of miles you have driven.
  2. Gallons Used (gallons): The total amount of fuel (in gallons) consumed during the journey.
  3. Cost per Gallon ($): The price of one gallon of fuel.

The formula for calculating MPG cost is straightforward:

MPG = Miles Driven / Gallons Used

Cost Per Mile = Cost per Gallon / MPG

How to Use

Using our simple calculator to determine your MPG cost is easy:

  1. Enter the Miles Driven in the first input field.
  2. Input the Gallons Used in the second field.
  3. Provide the Cost per Gallon ($)
  4. Click the “Calculate” button.

The calculator will instantly provide you with two important pieces of information: the Miles Per Gallon (MPG) and the Cost Per Mile.


Let’s illustrate this with an example:

  • Miles Driven: 300 miles
  • Gallons Used: 12 gallons
  • Cost per Gallon ($): $3.00

After inputting these values into the calculator and clicking “Calculate,” you will get the following results:

  • Miles Per Gallon (MPG): 25.00
  • Cost Per Mile: $0.12

This means that for every mile you drive, it costs you $0.12.
