Have you ever looked closely at a gas station sign and wondered about the tiny 9/10 at the end of the price? That fraction is worth about $1.2 billion a year to American gas stations — and about $5 a year to you. Every gallon of gasoline sold in the United States ends in nine-tenths of a cent. There is no coin for it, no law that requires it, and you never actually pay it — the pump rounds your total to the nearest cent. Yet it has survived for more than ninety years, outliving the tax that created it and, as of 2025, the penny itself. All figures below are as of November 14, 2026, unless noted. AAA put the national average for regular gasoline at $3.84 a gallon that day. What the 9/10 Actually Is The 9/10 is nine-tenths of one cent — $0.009 — added to the price of each gallon. It is measured in mills. A mill is one-thousandth of a dollar, an old unit of account that survives in tax and accounting math. The United States never minted a mill coin, and it never needed to: the fracti...

Should your next car run on gasoline or electricity? The honest answer is not a brand or a verdict. It is a number: how many miles you drive, and where you plug in. Your annual mileage and your charging habits decide which car is cheaper — not the sticker price. At today's prices, a home-charged EV costs about a third as much per mile as a gas car. But the EV costs more to buy, and if you can only charge at public fast chargers, most of that advantage disappears. All figures below are as of November 8, 2026. AAA put the national average for regular gasoline at $4.04 a gallon on November 7, down from $4.17 five days earlier. The U.S. Energy Information Administration's latest residential electricity average is 18.16 cents per kilowatt-hour (August 2026). The Per-Mile Math, in One Table Home-charged electricity costs about a third of gasoline per mile. Public charging costs nearly as much as gas. The unit that answers the question is cents per mile. The inputs: a gas c...

Want to know whether home prices are rising or falling in your city — not the national average? Four free sources publish a local house price index, and the one most people check first is the slowest. The Federal Housing Finance Agency covers every state and more than 400 metros. Case-Shiller covers the 20 biggest cities. Zillow goes down to the ZIP code. And the National Association of Realtors reports the actual dollar median for about 235 metros. Here is where each one lives, what it costs, and how fresh the numbers are. The Four Sources at a Glance All four are free to read at the source. The only catch is Case-Shiller: S&P's own site shows limited data, so the free route runs through the St. Louis Fed's FRED database.
