Examples
Interest stays in the chipper fund
You run a tree-care company and keep a chipper-replacement fund at a savings bank. On March 1 the principal is $14,600. The March 31 statement credits $38 of interest to the same account; you leave it there, debit the fund $38, and credit interest income $38, so principal is now $14,638. April 30 credits another $38 and the fund is $14,676. Open the Other Current Assets register in QuickBooks Online or Xero and confirm it matches the bank; if you book the $38 as a Checking deposit, the fund no longer ties to the statement.
Year-end profit lands in equity
You run a bakery. After the December 31 close, the P&L shows $27,850 of net income. The close adds that $27,850 to retained earnings (earned surplus) that already sat on the balance sheet; Checking does not go up by the same amount. In QuickBooks Online or Xero, run the year-end close so income and expense zero and the net hits Retained Earnings. Do not also park $27,850 in Checking as if the close created cash, and do not take that equity add as a draw without a separate owner's draw.
Why it matters
Accumulation is the periodic add-on that makes a balance larger: interest left in a reserve, profit closed into equity, or discount added onto an investment so its book value climbs toward what you will collect or pay. You will not see this on ordinary vendor bills. It shows up when a statement credits interest you leave in place, at year-end when net income moves to earned surplus, or each period you hold a discounted note. Skip those adds and the reserve or equity line is short of what already built. Treat the add as extra cash you can spend, or mix it up with an accrual of unpaid growth, and you will spend or accrue an amount that has already been added to principal.
