## Understanding the equity side of a balance sheet.

There's an old saying that it takes money to make money. Some might suggest otherwise; but if we look at a company's balance sheet, we find that, more often than not, this statement is true.

That's because companies often have to issue stock in order to start, fund, or grow a business. It's something that's known as paid-in capital, which is the amount of money that investors have directly invested in the company through either the purchase of common or preferred stock.

Paid-in capital formula
It's pretty easy to calculate the paid-in capital from a company's balance sheet. The formula is:

Stockholders' equity-retained earnings + treasury stock = Paid-in capital

In order to find the right numbers to plug in, an investor simply needs to head over to the equity section of a company's balance sheet and find those three numbers. Using a real-world example, here's a snapshot of the shareholder's equity section of Halliburton's (NYSE: HAL) balance sheet:

Data source: Halliburton Company Annual Report. Note: In millions of dollars.

To calculate Halliburton's paid-in capital, take its stockholder equity (\$16,267) minus its retained earnings (\$21,809), which is then added to the amount of Treasury stock (\$8,131). One thing that's worth noting about the treasury stock is that, while it's a negative on the balance sheet because it reduces shareholder equity, it's a positive value in our formula because it represents the amount of stock a company has repurchased with retained earnings.

Here's the outcome from that formula:

\$16,267-\$21,809 + \$8,131 = \$2,598

In other words, Halliburton investors have plowed nearly \$2.6 billion into the company in order to fund its ability to make money on their behalf.

Paid-in capital equation
In addition to that formula, there's one other way to calculate the paid-in capital. There's a two-step equation where we first subtract retained earnings from total stockholders' equity, and then add treasury stock to that result to calculate total paid-in capital. Here's that equation using our real-world Halliburton example:

1. \$16,676-\$21,809 = -\$5,533

2. -\$5,533 + \$8,131 = \$2,598 (Paid-in capital)

We get the same result, with just a slightly different method.
