I don't trust any of these estimates other than schools giving a program price. People told me my PPL would cost around $8k, I paid close to $20k. It was spread out over 5 years, which in the end meant I had to fly a lot more than most did since flights were often 2-4 months apart. There was one year I took only took 3 lessons, in the middle of trying to do solo XCs. I did it through an FBO, paid $55-60/hr for CFIs and $135-160/hr for airplanes depending on which one I ended up in.
I'd highly recommend anyone wanting to get into flying sets aside time and money to do it all as soon as possible, paying as you go can cause a lot of interruptions when life gets in the way. Hell, I'm trying to get checked out in a 172 as soon as I get paid on the 22nd. By the 25th, it will have been a year since the last time I flew. Makes me glad I didn't take a loan, I'm already about 11k in debt just because of life outside of flying. Can't imagine $60k+ of debt like some have.
