Residual Income: 동영상 및 연습문제
Residual income is an investment center performance measure that focuses on the amount of income left after meeting a required return. It is calculated as operating income minus target income, where target income is based on a required target ROI and the division’s average assets. The key formula is \(RI=\text{Operating Income}-(\text{Target ROI}\times \text{Average Assets})\) .
A positive residual income means the division used its assets more effectively than expected and earned more than the target return. A negative residual income means the division fell short of the target ROI, but it does not mean the division was unprofitable or operating at a loss. This method helps evaluate how well a division generates income relative to the return expected on the assets it controls, making Residual Income a useful alternative to ROI for performance evaluation.

Residual income (RI) in accounting is a performance measure used to evaluate investment centers. It represents the amount of income left after meeting a required target return on assets. The formula for residual income is given by: . Here, the target ROI is the minimum required return set by management, and average assets represent the investment base of the division. A positive RI means the division earned more than the target return, while a negative RI means it fell short, though it may still be profitable. This method helps assess how effectively a division uses its assets beyond just profitability.
Residual income (RI) and return on investment (ROI) are both used to evaluate investment centers, but they differ in focus. ROI measures the percentage return on assets, calculated as operating income divided by average assets. RI, on the other hand, measures the absolute dollar amount of income earned above a target return. While ROI shows efficiency as a ratio, RI shows the extra profit beyond expectations. RI is useful because it accounts for the cost of capital or target ROI, encouraging managers to invest in projects that add value rather than just increasing ROI. Therefore, RI can provide a clearer picture of value creation compared to ROI alone.
A positive residual income indicates that a division has earned more income than the target return set by management, meaning it used its assets more effectively than expected. For example, if the target ROI is 20% and the division achieves 23.39%, the positive RI reflects this extra 3.39% return in dollar terms. Conversely, a negative residual income means the division did not meet the target ROI, but it does not necessarily mean the division was unprofitable. It simply fell short of the expected return, indicating less effective use of assets. This distinction helps managers identify which divisions are truly adding value.
To calculate the target income when solving for residual income, you multiply the target return on investment (ROI) by the division's average assets. The formula is: . This target income represents the minimum income the division must earn to meet management's expectations. Once you have the target income, you subtract it from the actual operating income to find the residual income. This approach helps evaluate whether the division is generating returns above or below the required threshold.
Residual income is considered a useful alternative to ROI because it addresses some limitations of ROI. While ROI measures efficiency as a percentage, it can discourage managers from investing in profitable projects that might lower their division's ROI. Residual income, by focusing on the dollar amount of income above a target return, encourages managers to accept projects that add value even if they reduce ROI. This makes RI a better measure for evaluating how well a division generates income relative to the cost of capital or target return. It aligns managers' decisions with overall company value creation.
