What is a balance brought down and carried down?

Beginner

Answer

When balancing a ledger account, the balance carried down (c/d) is the figure inserted to make both sides equal at period end; the balance brought down (b/d) is that same figure entered on the opposite side as the opening balance for the next period. It's how running balances continue between periods.
Account: Dr side 800, Cr side 500 -> Balance c/d 300 (Cr side); Balance b/d 300 (Dr side).
Real-world example The cash account's closing balance is carried down and reappears as the opening balance next month.
