Fuel Cost Calculator
Calculate total fuel costs for your trip
About this Tool
The fuel cost calculator helps you estimate the total cost of fuel for a trip based on distance, your vehicle's fuel efficiency (MPG), and current fuel prices. This essential planning tool allows you to budget accurately for road trips, compare vehicle operating costs, or evaluate whether a long drive is cost-effective compared to other transportation options. By calculating cost per mile, you can also assess the true operating cost of your vehicle and make informed decisions about commuting, travel, or vehicle purchases.
Common Use Cases
Road Trip Planning
Budget accurately for vacations and long-distance travel. Estimate total fuel costs before departure to plan expenses and compare routes.
Commute Cost Analysis
Calculate monthly or annual commuting costs to understand transportation expenses, evaluate job offers in different locations, or assess remote work savings.
Vehicle Comparison
Compare operating costs between different vehicles when purchasing. Calculate long-term fuel savings of more efficient vehicles versus higher purchase prices.
Business Expense Tracking
Estimate mileage reimbursement, track business travel costs, or calculate delivery expenses for accurate invoicing and tax deductions.
Pro Tips
- !
Check Current Gas Prices
Gas prices vary by location and change frequently. Use apps like GasBuddy to find current prices along your route for accurate estimates.
- !
Know Your Actual MPG
Your real-world MPG is often lower than EPA estimates, especially in city driving. Track actual fuel consumption over several fill-ups for accurate calculations.
- !
Factor in Route Conditions
Highway driving typically achieves better MPG than city driving. Mountain terrain, traffic, and weather conditions can significantly affect fuel efficiency and costs.
- !
Compare Transportation Options
Calculate whether driving is more economical than flying, trains, or buses for long trips by comparing total fuel costs plus wear-and-tear to alternative fares.
