I have seen so many questions where they use either entire asset value or equity value in denominator . I use appropriate value and most time i am wrong.Looks like i am lagging behind …

Simplisticaly, Return on asset is equal to the net return (return - debt return) from liabilities (that is debt/leverage) and return from equity portfolio

compute the total dollar return on original capital plus borrowed funds. So if i had 70 and borrowed 30, and earned 10%, the dollar return would be 10.

subtract the dollar borrowing cost from total earnings. So if it cost me 5% to borrow 70, I subtract 3.5.

divide net gains (total dollar return - dollar borrowing cost) by the original investment. Leveraged return = (10-3.5) / 70 = 9.3%

Just easier for me to think in dollar terms vs. returns

I don’t ever use that formula either, and I have been successful on that.

I think it is better to focus on what is actually happening. How much are you going to make on your total assets (liabilities + equity), and how much is your borrowing cost. If you know that, then you can calculate the return on equity or assets.
