EIA reports weekly and monthly residential heating oil prices as separate aggregations. They are not the same number and are not averaged here.

Additional sourced observations are listed below and are not blended into this headline.

How to use this figure

Use this page to price heating-oil gallons at the EIA weekly residential average, and to keep the monthly average as a separate observation.

  1. Use the weekly $5.535 figure for the estimator. It is the week of 2026-03-30 and the cited table excludes taxes.
  2. Read the March monthly $5.126 figure beside it. Do not ask the page to average the two.
  3. Compare a dealer’s pre-tax or advertised gallon price in the gap box, and remember the EIA weekly figure excludes taxes.

What the result means

One hundred fifty gallons at the weekly price is $830.25. The monthly price would make a different product, so it is not substituted.

A comparison that stays on this source

Propane is another fuel. A propane gallon price does not belong in this field.

If the number looks wrong

  • A delivered price that includes tax can sit above this weekly figure for that reason alone.
  • The series date is the extracted heating-season week, not a live quote.

This does not size a tank or price a furnace replacement.

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 (75 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.

  • Not propane.

Questions

Which number is “the” price?

The weekly and monthly EIA figures are different aggregations. CostMage shows both and estimates with the weekly observation.

Why estimate with $5.535 instead of $5.126?

They are different EIA aggregations. CostMage will not blend them. The estimator is locked to the weekly figure; the monthly figure stays a separate observation.

Does this include taxes?

The cited EIA weekly residential heating oil average for that table excludes taxes.
