Estimate fuel cost for a road trip by distance and MPG.
Divide the trip distance by fuel economy to get the gallons burned, then multiply by the local fuel price for the cost. Fuel is the dominant variable road-trip cost, and knowing it up front helps plan budgets and compares against flying or rail.
Trip Fuel Cost
Fuel = distance / MPG; cost = fuel x price
Fuel = distance / MPG; cost = fuel x price Divide the trip distance by fuel economy to get the gallons burned, then multiply by the local fuel price for the cost.
