A fifth way to account for inflation is to use inflation-adjusted metrics, which are ratios or indicators that measure the performance, profitability, or efficiency of a company or a project, after adjusting for inflation. For example, you can use the real return on investment (ROI), which is the ratio of the real net income to the real investment. The real return on investment reflects the true profitability of a project, after accounting for the loss of purchasing power due to inflation. Another example is the real earnings per share (EPS), which is the ratio of the real net income to the number of shares outstanding. The real earnings per share reflects the true earnings available to shareholders, after adjusting for inflation. Inflation-adjusted metrics can help you compare different companies or projects, and assess their value creation potential.
