This method provides a practical way to estimate fuel expenses, which is especially useful for budgeting and understanding the financial impact of your vehicle's usage. Here's a step-by-step guide to help you calculate this:

First, determine your vehicle's fuel efficiency in miles per gallon (MPG). This value can be found in your car's owner's manual or on the vehicle's fuel efficiency sticker, which is often located on the inside of the driver's door jamb. MPG is a measure of how many miles your car can travel on one gallon of fuel. For example, if your car achieves 30 MPG, it means you can drive 30 miles for every gallon of gasoline.

Next, calculate the total gallons of fuel your vehicle consumes in a year. Multiply your annual mileage by the MPG to get this figure. For instance, if you drive 12,000 miles annually and your car has an MPG of 30, then you would use 12,000 / 30 = 400 gallons of fuel per year.

Now, you can estimate the annual fuel cost. Multiply the total gallons of fuel consumed by the current price of gasoline. Gas prices can vary, so you might want to use an average price from the past few months or a recent average. For this example, let's assume the current price of gasoline is $3.00 per gallon. So, your annual fuel cost would be 400 gallons * $3.00 = $1,200.

This calculation provides a straightforward way to estimate fuel expenses, which can be a valuable tool for budgeting and understanding the financial impact of your vehicle's usage. It's important to note that this method provides an estimate and actual fuel costs may vary based on factors like driving conditions, vehicle maintenance, and fuel price fluctuations.
