Really hard to pin down without knowing a lot of other things such as - your operating experience level, how you plan to do maintenance, purchase price, condition of the plane, time on engines, how much is financed, insurance, etc. But here are some ballpark numbers off the top of my head.

Payments - 100k per year
Insurance - 30k per year
Maintenance - 10-20k per year

For -20 engines, your hourly operating costs will depend greatly on what you start with, how you plan to maintain them, and how you operate them.

It costs about 150K to exchange for a fresh overhauled -20 if you have a good core.

Middle of the road estimate to hang a mid-time exchange engine with a fresh hot section - 100K

bottom end estimate to hang a mid to high time exchange engine with a pretty variable hot section status - 60K

Figure on doing hot sections every 2,000 hrs. -20's eat ct vane rings so figure minimum per engine of 15-20k, you might get away with less, but 30-40k is also not out of the question, it depends on what you start with You may get 3 or so hot section runs this way on a mid-cycle engine.

Fuel burn - 75 gal/hr
Pilot - 30-60/hr
