The simple version

Receipts is our promise to grade our own work. Most finance writers publish a hot take, the market moves, and they never come back. We do. When the data moves, we revisit the piece and tell you what is still true and what is not.

In our earlier article on gas crossing $4, we explained why pump prices had pushed back above $4 a gallon and what that meant for a typical household budget. The driver was the closure of the Strait of Hormuz and the broader energy disruption tied to the Iran conflict.

The price kept moving. AAA now reports a national average of $4.49 a gallon, the highest in four years. The cause is the same. The math is different.

The numbers, then and now

When we published, the national average was around $4.00 and the Real Cost math used that as the baseline.

This week the national average is $4.49, up $1.31 from a year ago, per AAA's Daily Fuel Gauge. WTI crude and RBOB gasoline futures, both reported by CME Group, remain elevated.

The framing of the story held. The pump number did not. If you have been reading the article as a fixed number, the real cost we showed you was understated.

The Real Cost lens at $4.49

Take a household driving 12,000 miles a year in a car averaging 25 miles per gallon. That is 480 gallons a year.

At $1.31 per gallon more than a year ago, that household is paying about $629 more a year on gas alone, before any other price changes.

If that $629 were invested in a low-cost index fund at a 7 percent annual return, it would grow to roughly $59,000 over 30 years.

Run the math for a less efficient vehicle or a longer commute and the number goes up fast. The Real Cost Calculator on the site lets you run it for your own situation.

What changed our grade

• What we got right. The framing that the Strait of Hormuz closure was the dominant variable, and that the pump price would track crude rather than easing on its own, has held up.
• What we got wrong. The Real Cost math used a lower baseline. Anyone reading the original article today should mentally adjust the dollar figures upward by roughly 12 percent.
• What we did not see. Consumer sentiment crashed harder than the inflation print alone would have predicted. The University of Michigan index fell to 44.8 in May, the third consecutive monthly decline and one of the lowest readings the survey has logged. The mood is worse than the math, and that affects spending behavior in ways the original piece did not address.

What this means

For your budget, treat the original article's dollar figures as a floor, not a ceiling: at $4.49 the real cost is roughly 12 percent higher than the version that used a $4.00 baseline. For a household driving 12,000 miles a year, that is about $629 more a year than last year on gas alone, and the Real Cost lens puts the 30-year opportunity cost near $59,000. The practical read is to run your own numbers (miles, fuel economy, and the current pump price) rather than the headline, and to remember that the framing held even as the price moved, so the cost side is real and a little larger than first shown.

What this is NOT

This is not a prediction about where gas goes next. It is not a recommendation to buy or sell anything. It is not advice to change your commute, your car, or your investment strategy. It is a public update on a piece we published, with the current numbers, sourced to primary data.
