### Return on Invested Capital (ROIC)

The return on capital or invested capital in a business attempts to measure the return earned on capital invested in an investment.

### ROIC Formula

`Return on Invested Capital (ROIC)` = `Net Operating Profit After Tax (NOPAT)` / `Invested Capital`

The Net Operating Profit After Tax (NOPAT) is calculated using the reported Earnings Before Interest and Taxes (EBIT) or Operating Income on the income statement adjusted for the tax liability.

`Net Operating Profit After Tax (NOPAT)` = `Operating Income` * (1 - `Income Tax Rate`)

There are two ways to calculate invested capital: One looks at the company's assets, and another looks at its financing from debt and equity. In this model, we are using the financing based approach.

`Invested Capital` = `Total Stockholders Equity` + `Total Debt` - `Cash and Short Term Investments`

We then adjust `Invested Capital` and `Net Operating Profit After Tax (NOPAT)`  for **capitalized R&D expenses**.

### Capitalizing R&D Expenses

As per prof. Aswath Damodaran's paper:
> "Research expenses, notwithstanding the uncertainty about future benefits, should be capitalized."

Capitalizing R&D expenses treats R&D as an intangible investment. We estimate a “research asset” as the sum of unamortized R&D based on the selected amortization period.

`Value of the Research Asset` = Sum of `Unamortized R&D Value`

We also record annual amortization of that asset.

`Amortization of Research Asset` = Sum of `R&D Amortization This Year`

We then adjust profitability and capital to reflect this treatment:

`ROIC Adjusted for Capitalized R&D` = `Adjusted NOPAT` / `Adjusted Invested Capital`

Return on Invested Capital (ROIC)

The return on capital or invested capital in a business attempts to measure the return earned on capital invested in an investment.

ROIC Formula

Return on Invested Capital (ROIC) = Net Operating Profit After Tax (NOPAT) / Invested Capital

The Net Operating Profit After Tax (NOPAT) is calculated using the reported Earnings Before Interest and Taxes (EBIT) or Operating Income on the income statement adjusted for the tax liability.

Net Operating Profit After Tax (NOPAT) = Operating Income * (1 - Income Tax Rate)

There are two ways to calculate invested capital: One looks at the company's assets, and another looks at its financing from debt and equity. In this model, we are using the financing based approach.

Invested Capital = Total Stockholders Equity + Total Debt - Cash and Short Term Investments

We then adjust Invested Capital and Net Operating Profit After Tax (NOPAT) for capitalized R&D expenses.
