Additional Paid-In Capital: Definition, Formula & Example
Investments and stocks can be incredibly complicated.
When you’re valuing a stock, you want to always make sure that you can be as accurate as possible. This is what’s known as the par value of a stock. It’s the baseline of what the stock is worth. Anything that’s above that value is known as something different.
That’s where additional paid-in capital (APIC) comes into play.
But what exactly is APIC?
We’ll take a closer look at the definition, the formula used, and an example of additional paid-in capital.

What Is the APIC Formula?
The formula that can be used to calculate APIC is as follows:

What Is an Example of APIC?
Let’s say that Company X issues 20,000 of new stocks. These are valued at $5 per share. The par value of the stock is $0.01 and the company has 250,000 common shares outstanding.
With this information, we can calculate the APIC of the stock:
APIC = ($5 – $0.01) x 250,000
So:
APIC = $1,247,500

What Is Par Value?
APIC represents the amount of money that is paid to the company that is above the par value of the stock. So it’s important to fully understand what par value means.
The word ‘Par’ comes from Latin. It means equal or equality. In this case, it signifies the value that a business gives to a particular stock during its IPO. This is valued before there is a market for the stock.
If a stock drops below its par value, then potential legal liability may occur. This often leads to companies trying to avoid this by setting their stock par values far lower than their actual worth.
What Is Market Value?
So if the par value is the value set by the business before the stock hits the market, the market value is the value set by the open market.
The market value is the actual price a financial instrument is worth. This is because the stock market decides the real value of a stock. The paid-in capital includes the par value of both preferred and common stock. On top of any amount that is paid in excess of par value.
Summary
Additional paid-in capital is a very useful way for businesses to generate cash. Especially as they don’t have to first put down any capital. For investors, they can make a very good profit by purchasing shares at a company’s IPO.
