$2,000,000 / $20,000,000
= 0.1
= 0.1 * 100%
= 10%
Therefore, Systems Corporation return of investment is 10%. To add, ROI is usually expressed as a percentage and is typically used for personal financial decisions, to compare a company's profitability or to compare the efficiency of different investments.
