I need a better realistic way to calculate COA. Anyone know of any that doesn't consider real estate?
I have found that COA calculators out there doesn't work for me. To give background, let's say I live in Area-A and make $100k. If I relocate to Area-B, according to COA calculators out there, it will be $60k, mostly due to real estate. The problem is since I own a place in Area-A, my real-estate value is actually lower than Area-B. Also, my transportation in Area-A cost less due to public transportation compare to Area-B where I would need a car, insurance, gas, etc.
I normally look at relocation in terms of how much money I would save at the end of year. I can save $20-25k in Area-A then but if job pays $60k in Area-B then I will only save about $5k. Granted, Area-B has better weather and probably better life-style changes (doesn't really matter since I spent most of the time on computer

).
So I need a better realistic way to calculate COA. Or any thoughts you guys have on relocation and COA.
Thanks.
