Here’s a wild one: most wells are not drilled straight down. They curve! Drillers purposely angle the hole to follow water veins underground, like a snake on a mission. So, your “150-foot well” might actually be 165 feet of angled hole. That means you’re paying for extra dirt-wrangling.
Also, drilling itself is only half the cost. The pump, wiring, and pressure tank can easily add another $2,000 to $5,000. Ever tried lifting a 100-pound pump out of a damp, dark hole? Neither have I, but I imagine it’s less fun than a root canal.

If you live in soft soil (hello, Midwest farmland), drilling is cheap—$10 to $25 per foot. But if you live in rocky terrain (hello, New England or the Rocky Mountains), you’re looking at $30 to $60 per foot. That’s because the drill has to grind through granite, which is basically nature’s middle finger.
I once heard a story about a guy in Texas who hit solid limestone at 20 feet. His well cost $22,000 for 300 feet. He now names his water “Perrier” to justify the expense.
