No mystery math
Every extra mile has a price.
Total = (tank gallons × price) + (extra miles ÷ MPG × price)
We assume you buy a full tank and value detour fuel at that station’s price. Dollar totals are rounded to cents before ranking. Your time, traffic and vehicle wear aren’t included. Yearly savings are an estimate, not a forecast.
