Owner’s equity

Owner’s equity is the owner’s residual claim on a business: what remains after you subtract everything the business owes (its liabilities) from everything it owns (its assets). It is the third side of the accounting equation — assets = liabilities + equity — and the section of the balance sheet that represents the owners’ stake in the company.

What it’s called depends on how the business is structured. In a sole proprietorship or partnership it appears as owner’s capital or partners’ capital. In a corporation it is shareholders’ equity — typically common stock plus retained earnings. The concept is the same in every case: the portion of the business that belongs to its owners.

Owner’s equity is the book value of the business to its owners — what would be left for them, on the books, if every asset were turned to cash and every debt paid. It rises when the business earns profit or the owner contributes capital, and falls when the business loses money or the owner takes money out. Watched over time, it is one of the clearest signals of whether a business is building value or drawing it down.

Like every balance-sheet figure, it is only as trustworthy as the bookkeeping underneath it. Owner contributions and draws posted to the wrong accounts, profit that never closed into equity, or stale balances all distort it — which is why reconciling the equity accounts, not just the bank, is part of a real cleanup.

They’re related but not the same. Owner’s equity is the whole owners’ stake — capital contributed plus accumulated profit, less anything taken out. Retained earnings is one component of it: the cumulative profit a business has kept rather than distributed. Equity is the total; retained earnings is the portion built up from profits over time.
