About MPG Cost Calculator

Who Runs MPGCostCalculator.com

MPGCostCalculator.com is an independent website owned and operated by Shakeel Lodhi, built and maintained together with the MPGCostCalculator.com team. We created it for drivers who want a quick, honest answer to everyday questions — what a road trip will cost in fuel, how much a daily commute adds up to each month, and how much a more efficient car would really save. We are not affiliated with any car maker, dealer, fuel retailer or insurer, and no company pays to influence the results.

Every formula on the site is the standard fuel-economy arithmetic used by the U.S. EPA and fueleconomy.gov, and every vehicle benchmark is based on published EPA combined ratings. We re-check the formulas, default values and benchmark ranges whenever we update the site; the content was last reviewed on November 11, 2026.

Core Principles We Follow

• ✓
  Standard EPA Fuel-Economy Math: Costs are calculated with the same distance ÷ fuel-economy × price arithmetic used by the EPA and fueleconomy.gov, and speed effects use published highway fuel-economy curves.
• ✓
  Privacy by Design: Zero tracking of your daily driving routes or financial records. All computation executes 100% locally inside your web browser.
• ✓
  US & Metric Units: Instant conversion between US Imperial standards (MPG, miles, gallons) and international Metric units (L/100km, kilometers, liters).
• ✓
  Actionable Comparisons: See exactly how much money you save by choosing a 34 MPG compact over a 16 MPG truck or by maintaining a steady cruising speed.
