Fuel Cost Calculator – Trip Gas Cost Estimator
Calculate trip fuel cost based on distance, fuel efficiency, and current gas price. Use this free online calculator for instant, accurate results now.
Cách tính chi phí nhiên liệu
The formula is straightforward: Fuel Cost = (Distance ÷ MPG) × Price per Gallon. First, divide the distance by your vehicle's fuel efficiency to get gallons needed. Then multiply by the current gas price.
For metric units, use km/L or L/100km. At 8L/100km and $1.50/L, a 500 km trip costs $60.
Mẹo để giảm chi phí nhiên liệu
Maintain proper tire pressure (under-inflated tires reduce MPG by up to 3%). Drive at steady speeds — highway fuel economy peaks at 50-60 mph for most vehicles. Remove unnecessary weight; every 100 lbs reduces MPG by ~1-2%. Use cruise control on highways. Accelerate and brake smoothly.
Xe điện tương đương
EVs use kWh per mile instead of gallons. At $0.13/kWh and 3.5 miles/kWh efficiency, the cost per mile is about $0.037 — roughly 3-5× cheaper than a 30 MPG gas car at $3.50/gallon ($0.117/mile). Use this calculator to compare ICE vs EV trip costs.
Frequently Asked Questions
Làm cách nào để tìm MPG của xe tôi?
Check your car's manual, the EPA FuelEconomy.gov database, or your vehicle's trip computer. You can also calculate it manually: fill your tank, drive until nearly empty, fill again and record gallons added, then divide miles driven by gallons used.
Điều gì ảnh hưởng đến hiệu suất nhiên liệu nhất?
Speed is the biggest factor — aerodynamic drag increases with the square of velocity. Air conditioning can reduce MPG by 5-25%. Cold weather thickens oil and increases rolling resistance. Highway driving is generally more efficient than city stop-and-go traffic.
Làm cách nào để chuyển đổi L/100km sang MPG?
Use the formula: MPG = 235.214 ÷ (L/100km). For example, 7 L/100km = 33.6 MPG. To convert MPG to L/100km: L/100km = 235.214 ÷ MPG.
