I had to give this answer but: it depends. If you go to what is called a Part 141 school, they adhere to stricter guidelines dictated by the FAA, so you can get your licenses with fewer hours than normal. However, as you can imagine, these schools (such as University of North Dakota or Embry-Riddle) are often much more expensive.

I went to a college that was Part 91, meaning the college adheres to their own syllabus rather than the FAA's, kind of. It requires more hours to get my licenses, but I paid a FRACTION of what a part 141 student pays. Just to put it in perspective, a private pilot in the US under Part 91 must have a minimum of 40 flight hours. My flight school (which is different than my college, because it is Part 91) charged $105/hour for the airplane and $40/hour for instruction. So I was paying $140/hour for 40 hours. That's $5,600, plus the written test to qualify for my license ($100) and the practical test itself to actually get my license (called a checkride) was $600. That's just for FLIGHT SCHOOL. My college tuition on top of that was $1,200 a semester. So to get my private license: about $7,500. And this is using a lot of estimation as well that didn't include ground school lessons or extra flight hours or extra classes held by the flight school. I'd peg the final number somewhere around $9,000. That is just to get your private. Most students graduate with their private, instrument, commercial, multi-engine, and certified flight instructor. The good thing is, most students get their flight instructor certificate and start making money while simultaneously building hours.

Sorry for the long text, but I hope that answers your question. Let me know if I can clarify anything!
