Step-by-Step Guide: How to Use the Gas Spending Calculator

Using the calculator is straightforward. You don’t need technical knowledge or math skills — just a few basic numbers about your trip and vehicle.

Here’s how it works:

1. Enter Your Total Distance (in miles):
   Input the total miles you plan to travel. For example, if your destination is 250 miles away, type “250”.
2. Input Your Vehicle’s MPG (Miles per Gallon):
   This represents your vehicle’s fuel efficiency. If your car averages 25 miles per gallon, enter “25”.
3. Add the Current Gas Price per Gallon ($):
   Type in the average cost of gas in your area, e.g., “3.75”.
4. Click “Calculate”:
   The calculator will process your inputs and show the detailed results, including total gallons needed and total cost.
5. View Your Results:
   After a short progress animation, your fuel cost details appear instantly. You’ll see four main figures:
   • Gallons Needed
   • Total Gas Cost
   • Cost per Mile
   • Round Trip Cost
6. Optional: Copy or Share Results:
   • Click “Copy Results” to copy your results for later use or reports.
   • Click “Share Results” to send your cost summary via social media or messaging.
7. To Start Over:
   Press “Reset” to clear all fields and start a new calculation.

Practical Example

Let’s say you’re driving from Los Angeles to San Francisco — approximately 380 miles one way.

• Total Distance: 380 miles
• Vehicle MPG: 28
• Gas Price: $4.25 per gallon

Results:

• Gallons Needed: 13.57 gallons
• Total Gas Cost: $57.67
• Cost per Mile: $0.15
• Round Trip Cost: $115.34

That means your round-trip journey will cost about $115 in fuel — helping you plan your travel budget more precisely.
