Why this exists.

PumpPain pulls EIA weekly retail gasoline prices after each Monday release — the same series the U.S. Department of Energy uses — and pairs them with EPA fuel-economy records (the fueleconomy.gov dataset) to show you what a tank actually costs. No login. No paywall. No GasBuddy-style station-by-station list that ends in a credit-card pitch.

Why this exists

Gas prices spike, the headlines explode, and nobody tells you what it actually costs your car to fill up this week. Most calculators are five years out of date or paywalled. We pull each EIA weekly retail release and surface it for free.

What makes us different

• EIA-backed. Same weekly retail series used by the U.S. Department of Energy.
• Independent. Not affiliated with GasBuddy, AAA, or any oil company.
• Free forever. Core calculator is and will stay free. Ad-supported.
• Crowdsource-friendly. Submit a ZIP price, earn a verified badge.

Who built it

PumpPain is an independent, one-person project. The person behind it stays unnamed by choice. Prices come from the EIA's public weekly survey and fuel-economy figures from the EPA's fueleconomy.gov data; the Methodology page explains how every number is built, including where each tank size comes from.
