I think the consensus is that you are really calculating how much disposable income you can afford to put into an aircraft for your convenience and pleasure, and not wether this is a cost effective venture.

If this were a business venture then the profit/loss analysis would apply.

Right now the loss analysis is probably what your looking at.... eg. how can I cut my losses.

I understand you dilema my brother and I with you, but every number I enter comes out a loss, or nearly so.

Best to You,
