Stock Return Formula

Initial Investment

$\text{Initial Investment} = \text{Purchase Price per Share} \times \text{Number of Shares} + \text{Buy Commission}$

Final Stock Value

$\text{Final Value} = \text{Selling Price per Share} \times \text{Number of Shares} - \text{Sell Commission}$

Price Gain or Loss

$\text{Price Gain/Loss} = \text{Final Value} - \text{Initial Investment}$

Price Return

$\text{Price Return (\%)} = \frac{ \text{Price Gain/Loss} }{ \text{Initial Investment} } \times 100$

Total Dividends

$\text{Total Dividends} = \text{Dividend per Share} \times \text{Number of Shares} \times \text{Dividend Payments}$

Total Return

$\text{Total Return (\%)} = \frac{ \text{Price Gain/Loss} + \text{Total Dividends} }{ \text{Initial Investment} } \times 100$

CAGR (Annualized Return)

$\text{CAGR} = \left( \frac{ \text{Final Value}+\text{Dividends} }{ \text{Initial Investment} } \right)^{\frac{1}{\text{Holding Period}}} - 1$

Average Annual Return

$\text{Average Annual Return} = \frac{ \text{Total Return} }{ \text{Holding Period} }$

Manual Calculation Example

Suppose you purchased:

• Purchase Price = $50

• Shares = 100

• Selling Price = $75

• Holding Period = 3 years

• Buy Commission = $0

• Sell Commission = $0

Step 1: Initial Investment

$50 \times 100 = \$5{,}000$

Step 2: Final Value

$75 \times 100 = \$7{,}500$

Step 3: Profit

$\$7{,}500 - \$5{,}000 = \$2{,}500$

Step 4: Price Return

$\frac{2500}{5000} \times 100 = 50\%$

Step 5: Average Annual Return

$\frac{50}{3} = 16.67\%$

Step 6: CAGR

$\left( \frac{7500}{5000} \right)^{\frac{1}{3}} - 1 = 14.47\%$

Results

• Initial Investment: $5,000

• Final Value: $7,500

• Profit: $2,500

• Price Return: 50.00%

• Average Annual Return: 16.67%

• CAGR: 14.47%

If the stock also paid $1.50 quarterly dividends for three years, total dividends would increase the final return, resulting in a higher overall investment return.
