How this instrument works
Retained earnings is a running equity balance, not a single period's result: it is every dollar of profit a company has ever earned and chosen to keep, rather than distribute to shareholders, from the day it was founded up to today. The roll-forward is arithmetic, not judgment — take last period's ending balance, add this period's net income, subtract whatever cash left as dividends, and the new ending balance is the one figure that appears in the equity section of the balance sheet. It is the single line item that physically links the income statement, which resets to zero every period, to the balance sheet, which never resets at all.
A controller closing the books each quarter uses exactly this roll-forward to prepare the statement of retained earnings before carrying the new ending balance into next period's opening line. It is also how corporations reconcile Schedule M-2 on a U.S. tax return, and how an analyst reading two years of balance sheets, without a cash-flow statement in hand, can back into how much a company actually paid shareholders: beginning plus reported net income minus ending balance. A software company plowing every dollar into growth might show a beginning balance climbing in step with net income, quarter after quarter, because the dividends field sits at zero.
The balance can fall as readily as it rises. A loss year subtracts from the total exactly as a profit year adds to it, and a company that has lost more, cumulatively, than it has ever earned carries a negative retained earnings figure, called an accumulated deficit, printed on the books in parentheses. This simple three-line version also has real limits: it does not separate a stock dividend, which shifts value into paid-in capital without touching cash, from a cash dividend, which this instrument assumes; and it ignores prior-period restatements or treasury-stock transactions that some companies also route through the same equity account.
- Enter Beginning retained earnings, $ — the ending balance carried over from the prior period's books.
- Enter Net income for the period, $ from the income statement; enter it as a negative figure if the period was a loss.
- Enter Dividends paid, $ — the total cash distributed to shareholders during the same period.
- Read Ending retained earnings, $ — the new balance that carries forward into the equity section of the balance sheet.
Worked example — a $500,000 opening balance, a profitable year
A company closes last year's books with $500,000 of retained earnings on the balance sheet. Over the following year it earns $150,000 of net income and its board declares $50,000 in cash dividends. Enter beginningRE 500000, netIncome 150000, dividendsPaid 50000, and the roll-forward gives 500,000 + 150,000 − 50,000, an ending retained earnings of exactly $600,000.
That $600,000 becomes next period's beginning balance, and the arithmetic repeats. Notice what the figure does not say: it does not mean the company is sitting on $600,000 in cash. Most of it is already tied up in inventory, receivables, or equipment bought with prior years' profit — retained earnings tracks how much profit stayed in the business, not where the money currently sits.
Questions
Can retained earnings be negative?
Yes. If a company's cumulative losses and dividends ever exceed its cumulative profit since founding, the running balance goes negative — an accumulated deficit, usually shown in parentheses on the balance sheet. Enter a negative Net income for the period to see it: a loss year subtracts from the balance exactly as a profit year adds to it, with no floor stopping it from going below zero.
Does retained earnings mean the company has that much cash on hand?
No, and this is the most common misreading of the figure. Retained earnings is an equity balance recording how much profit was kept rather than distributed; it says nothing about where that value currently sits. Most of it is typically tied up in inventory, receivables, equipment, or debt paydown from past years, not sitting as cash in a bank account waiting to be spent.
How is retained earnings different from net income?
Net income is one period's profit, reported on the income statement, and the account resets to zero at the start of every new period. Retained earnings is the cumulative total of every period's net income, minus every period's dividends, carried on the balance sheet without ever resetting. This calculator is the bridge: it takes one period's net income and folds it permanently into the running balance.
Where does the beginning retained earnings figure come from?
It is simply last period's ending retained earnings, copied forward unchanged as this period's opening balance — the same number that appeared on the prior balance sheet's equity section. For a brand-new company preparing its first statement, the beginning balance is zero, since there is no prior period to carry a figure from.
Do stock dividends affect this calculation the same way as cash dividends?
No. A cash dividend, the kind this instrument assumes, reduces retained earnings and reduces cash by the same amount. A stock dividend also reduces retained earnings, but the value moves into paid-in capital instead of leaving the company, so no cash goes out the door. If a company issued only stock dividends, enter their fair-value amount in Dividends paid to see the reduction, understanding no cash actually left.
Is this the same thing as the dividend payout ratio?
No, though the two are related. The payout ratio is a single period's percentage — dividends divided by that period's net income. Retained earnings is a cumulative dollar balance built from every period's net income and dividends since the company began, not a percentage of any one year. A company can have a modest payout ratio this year and still carry decades of accumulated retained earnings on its books.
