Gas Cost Per Month Calculator

Formula

The formula to calculate the gas cost per month (CGM) is:

$CGM = \frac{M}{MPG} \times GC$

Where:

$CGM$ is the gas cost per month ($/month)
$M$ is the monthly miles driven on average
$MPG$ is the miles per gallon of the car
$GC$ is the average cost of gas for the month ($/gallon)

What is the Average Gas Cost Per Month?

The average American household spends about $250 per month on gasoline. That’s about $2,900 per year. If you drive a car that gets 30 miles to the gallon, then you’ll spend about $60 per week at the pump.

Example Calculation

Let's assume the following values:

Monthly Miles Driven ( $M$ ): 1000 miles
Miles Per Gallon ( $MPG$ ): 25 MPG
Cost of Gas ( $GC$ ): $3.50 per gallon

Step 1: Calculate the gas cost per month:

$CGM = \frac{1000}{25} \times 3.50 = 140 \text{ dollars}$

Therefore, the gas cost per month is $140.
