Who Runs This Site
GasBudgetCalculator.com is an independently owned and operated website founded and maintained by Shakeel Lodhi. It is not affiliated with any automaker, fuel retailer, insurer, or lender, and no company pays to influence the results. The calculator, its formulas, and the content on this site are written, tested, and maintained directly by Shakeel Lodhi, and are updated whenever we find an error or a better reference source.
What We Care About
- Precision Mathematics: Calculations use the standard fuel-cost formulas (distance ÷ fuel economy × price per unit of fuel) with exact unit conversions, so the results match what you would get by hand for the same inputs.
- Privacy by Design: Zero tracking of your daily driving routes or financial records. All math runs in your browser.
- Unit Freedom: Instant conversion between US Imperial standards (MPG, miles, gallons) and international Metric units (L/100km, kilometers, liters).
- Actionable Insights: Beyond just spitting out numbers, the tool shows whether upgrading to a hybrid or modifying your speed actually saves you meaningful money.
How Our Calculations Work
We analyze two primary driving modes:
Data Sources & Accuracy
Default values and vehicle benchmarks are based on publicly available reference data: combined fuel-economy ratings published by the U.S. Environmental Protection Agency on FuelEconomy.gov, and national average retail gasoline prices reported by the U.S. Energy Information Administration. Pump prices change weekly and your real-world fuel economy depends on how and where you drive, so always enter your own figures for the most accurate budget.
Results are estimates for planning and budgeting. They are not financial, tax, or mileage-reimbursement advice. If you spot an error, tell us and we will review and correct it.
