Gas Station Hopkinsville, KentuckyYears ago I read that a gasoline station doesn’t make money by selling gasoline.  The gasoline draws people to the station, and some of those people buy tiny $3 bags of Cheetos to go with their gasoline.  The margin on the gasoline is tiny, but the margin on tiny bags of Cheetos is not tiny.

Writing a blog works the same way.  A blogger doesn’t make any money by posting content.  The content draws people in, and a few people click on ads.  At least that’s what I hear.

Back to gasoline.  All these years I’ve marveled at the gasoline business model:

  • Sell a popular low-margin product to draw in crowds;
  • Make high margin products easily available;
  • Hope that some people buy the high margin products.

When I stop at a gas station I fill up my tank and I leave.  Unless I’m traveling a long distance I never go in to buy something.  Even worse for the gas station, I always use my American Express Blue Cash or my Discover Gas Card, both of which pay 5% cash back on gasoline.  The gas station gets charged a higher fee for rewards cards than other credit cards. 

Since I use a rewards card and don’t buy Cheetos, I always figured gas stations might actually lose money when I buy their gas.  That would make me a gas station’s worst nightmare. 

I’m Not Their Worst Nightmare After All

A few days ago I learned that “gasoline accounts for 70 percent of a typical station’s revenues, but only 30 percent of its profits.

It surprised me for two reasons:

  • If gasoline is 70 percent of revenues, then the other 30 percent is Cheetos and other junk food.  Check my math, but if the average price of a fill up is $50, then the average motorist is buying $21 of Cheetos per stop. 
  • 30 percent of profits on gasoline is a lot more than I had thought.  For years I thought it was basically zero.  If the gas stations are making 30 percent or their profits on gasoline, then their margin on gasoline is much higher than I thought, which means they’re not losing money when I use my rewards card, which means I’m not their worst nightmare. 

I never felt guilt when I thought gas stations were losing money on me.  But it’s nice to know the gas station can make a small profit even if I don’t buy Cheetos.
