Not realistic both price and time wise.
I think the easiest is PPL, which I spent about a couple months training 60 hours, to add a 2 month Covid shutdown and a 1 month wait time for an examiner plus a reschedule, then you have the written to study for, schedule and attend to and pass.
If you say about $200 per hour for plane and instruction, 60 X $200 = $12k plus the exam fee and checkride. That doesn’t include travel time, gas, meals, etc. However you want to calculate it.
Then for instrument training, I probably did another 75 hours, I enjoy flying with my instructor and just made it part of my routine. You can save money finding another student but my instructors hourly rate was $45/hr, still is, and I don’t mind paying it. I’m not charged extra for ground time unless it’s doing logbook sign-offs for checkrides. I probably spent 7 months on instrument training, including rescheduling the checkride a few times due to weather. On that calculation you’re looking at 15k plus exam and checkride fees and any other costs (gas, time, meals, etc).
For commercial, I took my time on that, it was about another 1.5 years, then it’s a lot of work to get to the 250 hours, I probably had closer to 300 hours, so if you count hours since last checkride it’s about 165 hours. So total cost about 33k plus exam fees. Now granted I did a lot of traveling to places, got my own airplane, which I’m not discounting since maintenance costs are real and things do break. I had to reschedule checkrides a lot for CPL and I had personal / work travel to attend to, so I was also busy and available less during this period. The hours is time building, not skills building or learning per say. This one you could do cheaper but I doubt it, renting an airplane and fuel is not cheap no matter how you put it, and you could definitely do it a lot faster but it’s a lot of flying. You’ll need breaks now and then.
PPL 60 hrs 12k (4-5 months)
IR 75 hrs 15k (7 months)
CPL 165 hrs 33k (19 months)
Checkrides 3k
Exam fees 600
Complex extra rental fees 1k
HP extra rental fees 1k
Tailwheel was 200/hr even
Approx 65,600 PPL IR CPL (30-31 months)
Fuel driving to airport
6 gallons roundtrip to airport
Let’s say $5/gal average X 6 = $30
Avg 2hrs per lesson (150 trips to airport)
150 X 30 = $4500
Meals?
Easily pushing 70k and I haven’t really kept track.
That’s not counting fuel premiums at destinations, airport landing and parking fees, other instructors higher hourly rates, etc.
I’m guessing I could do CFI with approx 20-30 hours more training. The materials for the written are a lot and I’m not sure that I’ll use it, so I have placed this on pause for now, I rather do the multi. So add about 4-6k plus checkride and exam fees.
My hours include complex, HP, and tailwheel endorsements, also my total time includes checkride aircraft rental time so I think it’s roughly approximate enough.
