I’m not sure the question is clear. Ownership and operating costs are not the same
I would characterize ownership costs as those which must be paid, regardless of if you fly or not. Insurance, hangar, database, annual,etc. in my spreadsheets I call this overhead.
Then there’s the cost to operate the damn machine. Fuel, oil/oil changes, reserve for engine/propellor, etc
The more you fly, the higher price paid overall for consumables, but the fixed overhead costs are spread out over the hours, resulting in a “lower” hourly operating cost
For example, my fixed costs to hangar and maintain an airworthy Cessna R172K is about $8300, whether I fly it or not. My current operating costs at $6 a gallon for 100LL is $97.47 an hour.
I fly about 125 hours a year, so my total cost is about $20300, which boils down to $162 an hour total cost. Flying 200 hours a year drops the cost to $137 an hour ($27,600 total)
So what’s the real question here? It is possible to control some of the fixed costs, but not so much the consumable cost. Your choice of airframe will drive both get a cheap C150, and your numbers may be half of what I mention. Buy a Cirrus, you can double them. Choice is yours
I can share my excel spreadsheets if you need an example
