**Introduction:** Planning a road trip? One of the key factors to consider is the cost of gas for your journey. Calculating the gas cost not only helps you budget for your trip but also contributes to a more efficient and enjoyable adventure. In this article, we provide a simple calculator and step-by-step instructions on how to calculate the cost of gas for your upcoming journey.

**Formula:** To calculate the cost of gas for a trip, you need to consider the distance to your destination, your vehicle’s miles per gallon (MPG), and the current price per gallon of gas. The formula is straightforward:

Gas Cost = (Distance / MPG) x Price Per Gallon

**How to Use:**

- Enter the distance of your trip in miles in the designated field.
- Input your vehicle’s miles per gallon (MPG).
- Specify the current price per gallon of gas.
- Click the “Calculate” button.
- The calculated gas cost will be displayed in the result field.

**Example:** Let’s say you’re planning a road trip covering a distance of 300 miles, and your vehicle has an MPG of 25. The price per gallon of gas is $3.00. Using the formula, the gas cost for your trip can be calculated as follows:

Gas Cost = (300 miles / 25 MPG) x $3.00 per gallon Gas Cost = (12 gallons) x $3.00 per gallon Gas Cost = $36.00
