The EIA weekly U.S. regular retail price is a national average including taxes, not the price at a named station.

How to use this figure

Use this page to price a number of gallons at the EIA weekly U.S. regular retail average, then compare a station price you saw with that average.

  1. Confirm the week on the source line. The locked price is the national all-formulations regular price, including taxes, for that week.
  2. Enter gallons. The total is gallons times that weekly price.
  3. Type a station’s price per gallon only in the comparison. It is your observation, not a second EIA series.

What the result means

Twelve gallons at $4.071 is $48.85. A station above or below $4.071 is normal. The page does not name the station or predict tomorrow.

A comparison that stays on this source

Diesel and premium are not in this estimator. Heating oil is a different fuel and a different EIA table.

If the number looks wrong

  • If the week looks old, the limitation is the latest extracted weekly observation, not a live pump feed.
  • Do not enter a city name. No city average was extracted.

The per-mile page is an IRS convention. It is not this retail gasoline price.

Record last verified 2026-09-06. That date is the record’s verification stamp, not a claim that a market price is unchanged today.

Official unit price: the headline is a published series observation. Any total is quantity × that sourced rate.

High evidence confidence

High evidence confidence is an internal CostMage evidence-quality score (81 of 100). It describes source strength and extract completeness, not the probability that a quoted figure matches your bill.

Labels: 75–100 high, 60–74 moderate, below 60 limited. The number is not a probability that the cost is correct.
