I looked up Microsoft to see how they compare financially, these were my findings:

ROI (return on investment)= 10.69.%. This value is calculated by dividing net sales by investments. Its not great, should be above 20%.
ROA (return on Assets) = 6.63. This seems low.
ROE (return on Equity)= 21.37% . This is probably the most important metric to evaluate a company by. It compares the income available to equity investors to the capital owned by equity investors. The average of more than 7,400 publicly traded US firms was 10.38% so Microsoft appears to be doing ok.
