Stocks are part of any successful asset allocation plan and give investors part ownership in a business. If you want to calculate stock valuation, the TI-84 is an ideal calculator for the purpose. You can calculate many different stock valuations on the TI-84, including the zero growth case, which implies that the stock has matured. The formula for zero growth is P = E/R, where P is the stock price, E is the stock earnings and R is the discount rate.

## Step 1

Type the stock's earnings into the calculator. For example, enter $50 as "50."
