Retained earnings and equity, explained

Retained earnings is one of those balance-sheet lines people nod at without quite knowing what it is. It’s actually a simple and important idea — the bridge between the profit a business makes and the equity it builds — and it explains a common post-conversion puzzle.

What equity is

Equity is the owners’ stake — what would be left for them if the business paid off everything it owed. In the accounting equation, it’s the balancing third piece: Assets = Liabilities + Equity.

What retained earnings is

Retained earnings is the accumulated profit a business has kept — earned over the years and not paid out to owners. Each year, the net profit from the income statement flows into retained earnings, increasing equity; a loss decreases it; and money distributed to owners reduces it. It’s the running total of “profit we made and held onto.”

How it connects the two statements

This is the link between the income statement and the balance sheet. The P&L measures one period’s profit; at period end that profit rolls into retained earnings on the balance sheet. That’s why the two statements tie together — the bottom of one feeds the equity of the other.

Why it trips people up after a conversion

When you migrate a file mid-life, the accumulated history has to land somewhere — and if opening balances aren’t set correctly, prior profit can end up in the wrong equity account, or a mystery balance appears in Opening Balance Equity that should have been retained earnings. Sorting equity is part of landing a clean opening position.
