Common Stock vs Additional Paid-In Capital (APIC): What's the Difference?
Short answer. Both sit in shareholders’ equity. The common stock line records the par value of shares issued, usually a token amount such as $0.01 a share. Additional paid-in capital (APIC) records everything investors paid above par. Add the two to see the total cash a company raised by selling stock.
Side by side
| Common stock (par value) | Additional paid-in capital | |
|---|---|---|
| What it records | Par (nominal) value of shares issued | Amount received above par value at issue |
| Typical size | Small: par is often $0.01 or $0.001 | Large: most of the money raised |
| Where it appears | Shareholders’ equity on the balance sheet | Shareholders’ equity, directly below common stock |
| Example | 1,000,000 shares x $0.01 par = $10,000 | Shares sold at $20: ($20 - $0.01) x 1,000,000 = $19,990,000 |
| Changes when | New shares are issued or retired | Shares are issued above par, or stock-based pay is expensed |
| Affected by market price | No, fixed at issue | No after issue; only new issuance changes it |
| Legal meaning | Legal capital in many jurisdictions | Accounting category with no par-value rule attached |

Frequently asked questions
Is APIC an asset?
No. It is an equity account that records where owners’ money came from; it is not cash the company still holds.
Does the stock price change APIC?
No. APIC records what was paid at issue. Later trading between investors does not change the company’s books.
Why is par value so low?
Par is a legal nominal figure set in the charter, often a fraction of a cent. It rarely has any link to market value.
