• AFM is the average annual fuel margin ($/gallon) • GS is the total amount of gas sold in the year (gallons) To calculate Gas Station Profit, multiply the average annual fuel margin by the number of gallons of gas sold in the year. How to Calculate Gas Station Profit? The following steps outline how to calculate the Gas Station Profit. 1. First, determine the average annual fuel margin ($/gallon).
2. Next, determine the total amount of gas sold in the year (gallons).
3. Next, gather the formula from above = GSP = AFM * GS.
4. Finally, calculate the Gas Station Profit.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

average annual fuel margin (\$/gallon) = 0.15

total amount of gas sold in the year (gallons) = 60,000
