Total Fuel Cost vs Trip Distance
公式
Road Trip Fuel Cost
Knowing your fuel costs in advance helps budget for road trips and compare driving vs flying.
Formula
Gallons Needed = Distance / MPG
Total Cost = Gallons x Gas Price
Cost per Person = Total Cost / Passengers
Road trips become more cost-effective with more passengers. A 500-mile trip at 28 MPG and $3.50/gallon costs about $62.50 total, or just $31.25 split two ways.
计算示例
A 500-mile trip in a 28 MPG car at $3.50/gallon with 2 passengers.
- 01Gallons = 500 / 28 = 17.86 gallons
- 02Total cost = 17.86 x $3.50 = $62.50
- 03Per person = $62.50 / 2 = $31.25
- 04Cost per mile = $3.50 / 28 = $0.125/mile
常见问题
Should I include wear and tear?
The IRS mileage rate ($0.67/mile in 2024) includes fuel, maintenance, insurance, and depreciation. For a more complete cost picture, multiply distance by this rate.
Is driving or flying cheaper?
For 1-2 people on trips under 500 miles, driving is usually cheaper. With 3-4 people, driving wins up to 1,000+ miles. Factor in time value and fatigue.
How does speed affect fuel cost?
Most cars are most efficient at 45-65 mph. Above 65 mph, each 5 mph increase costs roughly 7-14% more fuel due to aerodynamic drag increasing with speed squared.
