EIA-tracked states only — the 9 with a weekly state series. The other 41 are ranked by regional average on /states.
What this site is
PumpPain is a gas-cost calculator. We take the week's price of regular gasoline, the tank size and EPA combined MPG of the car you pick, and show what one fill-up costs, then what that works out to per month and per year at the miles you drive.
The price comes from the U.S. Energy Information Administration's weekly retail gasoline survey, the same table EIA publishes every Monday afternoon at eia.gov. We pull each release once it is out, store it, and rebuild every page on the site from that one file, so every page shows the same week's number. Tank sizes and MPG come from the EPA's fueleconomy.gov database, with our own corrections for models whose tank changed between generations.
EIA's survey is a sample of stations sized to estimate the national average and seven regional averages, not fifty state averages. It publishes a weekly state figure for only 9 states: California, Colorado, Florida, Massachusetts, Minnesota, New York, Ohio, Texas, Washington. For the other 41 we show the average of the PADD region the state sits in, labelled as regional on the state page, in the calculator and in the weekly roundup. It is a real EIA number, just not specific to your state.
How to read the number
The fill-up cost is a range. The low end is a typical fill, 85% of the rated tank, because most people pull in near the warning light and the pump clicks off a little short of the rated capacity. The high end is the rated tank filled from empty, which you will rarely pay. The monthly and annual figures use EPA combined MPG, a test-cycle number; if your real MPG is lower, your real cost is higher by the same proportion.
What changes from week to week is the price: the national and regional averages, the 9 state figures, and the 12-week trend lines. The vehicle data does not change weekly. If our copy of the EIA data falls more than 14 days behind, a banner at the top of every page says so. The full method is on the methodology page.
