13 MPG
13 MPG Calculator
The 13 miles per gallon calculator shows exactly what it costs to run a vehicle that returns 13 MPG. That figure is typical of large pickups, full-size SUVs, classic muscle cars, and thirsty performance engines — vehicles where fuel is a major ongoing expense. With the MPG fixed at 13, you only need your trip distance and gas price to see the cost.
Enter the miles you plan to drive and the price per gallon, and the calculator returns total fuel cost, gallons needed, cost per mile, and an annual estimate. Because 13 MPG sits well below the US average of around 26–28 MPG, the numbers add up quickly — which is exactly why seeing them in clear dollar terms helps with budgeting and with deciding whether a more efficient vehicle would pay off.
Below the calculator you'll find a breakdown of what kinds of vehicles average 13 MPG, plus a cost table covering common trip distances and gas prices. For other figures, compare with our 18 MPG calculator, and use the MPG Cost and Truck MPG tools for fully custom inputs.

Yes. The EPA considers anything under 20 MPG to have poor fuel economy. At 13 MPG, you’ll spend significantly more on fuel than the average driver. However, for heavy-duty work trucks, this is expected and acceptable.
Keep tyres properly inflated, remove unnecessary weight, avoid idling, and use cruise control on highways. Switching to a diesel version of the same vehicle class typically adds 25–35% fuel economy.
