Residual Income Calculator
We built this residual income calculator to help you calculate a company's residual income. Residual income is a very useful metric used to value a company. Residual income is widely use in company valuation as it measures economic profit instead of accounting profit.
This article will help you understand what is the residual income meaning and how to calculate residual income. We will also show you some examples to help you understand how to apply the residual income model.
What is residual income? Residual income definition
We can understand the residual income as economic profit. The residual income definition is income after deducting all the equity charges from the accounting net income, where the equity charges reflects the opportunity cost of capital of the equity stockholders.
The accounting net income is often stated after deducing a company's interest expenses, which means it takes care of the cost of debt. However, it does not reflect the cost of the equity capital. Hence, from the equity holder's perspective, one can argue that accounting net income often overstates the returns to the stockholders.
We can solve this problem by calculating the residual income, which considers the cost of equity by deducting the equity charge from the accounting net income. In short, the residual income meaning is the return after all capital costs, both debt and equity, are deducted.
How to calculate residual income using the residual income formula?
To understand the residual income model, we must first understand its formula.
Let's take Company Alpha, which reports the following information, as an example:
 Company: Company Alpha;
 Net income: $80,520,000;
 Return on equity: 12.3%; and
 Equity capital: $800,000,000.
There are 3 steps that you need to take to calculate the residual income.

Determine the company's net income
The company's
net income
can be found on the income statement of most companies. It is the bottom line of a company, sonet income
will always be the last line of the income statement. It is recommended that you get this information from the company's annual report.In our example, the
net income
of Company Alpha is$80,520,000
. 
Calculate the company's equity charge
The next thing we need to do is to calculate the company's
equity charge
. Theequity charge
reflects the cost of opportunity for all the equity holders. It is defined as the product ofequity capital
and thecost of equity
.Equity capital
, or total stockholders' equity, is the amount of equity being injected into the company by its shareholders. Theequity capital
is displayed in the company's balance sheet. For Company Alpha, theequity capital
is$800,000,000
.The cost of equity can be calculated using various methods. The most common method being the Capital Asset Pricing Model (CAPM). In our example, the
cost of equity
for Company Alpha is12.3%
.Now, the
equity charge
can be calculated using the following formula:equity charge = equity capital * cost of equity
The
equity charge
for Company Alpha can be calculated as:$800,000,000 * 12.3% = 98,400,000
. 
Calculate the residual income using the residual income formula
Lastly, we need to calculate the
residual income
for Company Alpha. Theresidual income
formula is displayed as follow:residual income = net income  equity charge
Hence, the
residual income
for Company Alpha is$17,880,000
.
The importance of residual income
Now, let's understand the residual income meaning further.

Residual income helps us to understand economic profit
Calculating the residual income allows us to understand the economic profit that a company is generating. The net income, or net profit, reported on the income statement only takes into account the cost of debt, which is reflected by the interest expenses. However, this is not very useful for stockholders as the cost of equity is not reflected in net income. Calculating residual income is one of the best ways to solve this issue as it reflects the actual income going to the stockholders.
For instance, Company Alpha seems profitable as it has a positive net income. However, after deducting the equity charge from the accounting net income, Company Alpha is actually economically unprofitable, given its negative residual income.

Residual income is also useful in performing a company valuation
According to the residual income model, the share price of the company is equivalent to its book value per share plus the present value of its residual income per share (
PV
) . This can be shown as:share price = book value per share + PV
Hence, calculating residual income can help us value a company as well.
