Fuel Cost Calculator

Fuel Cost Calculator gives you a clear estimate from the values you already know: trip distance, vehicle fuel economy, and fuel price.

Calculate one-way or round-trip fuel cost, switch between common US and metric units, and see both estimated fuel used and total cost. Open the breakdown to review the formula and the values used for the estimate.

Save a vehicle profile and recent estimates for repeat trips. Search and organize local records, split an estimate across passengers, or share the current result. Optional Premium tools add unlimited saved estimates, multiple profiles, reusable templates, three-price comparison, and single or batch PDF/CSV reports with a one-time purchase.

Your trip records stay on your device. No account is required, and the app does not use ads, analytics, live fuel prices, GPS, maps, or cloud sync.

Key features:
• Trip fuel cost and fuel-used estimates
• Miles or kilometres
• MPG (US), MPG (imperial), km/L, and L/100 km
• Price per US gallon, imperial gallon, or litre
• One-way, round-trip, and passenger-split results
• Visible formula and input breakdown
• Local vehicle profiles and saved estimates
• User-directed backup, restore, share, PDF, and CSV tools
• Editable notes and tags for saved estimates
• Export history for successfully saved report files
• Light, dark, and system themes

Estimates use the values you enter. Actual fuel use and prices may vary.
