Balance b/d vs Balance c/d in Bookkeeping

Balance b/d (“balance brought down”) is the opening balance carried into a new accounting period; balance c/d (“balance carried down”) is the closing balance used to make a ledger account balance at the period’s end. They are two labels for successive steps in balancing an account, not two different kinds of income, expense, or cash.

What the abbreviations mean

The abbreviations come from traditional bookkeeping language. “Brought down” describes bringing a balance forward to the next period, while “carried down” describes carrying it to the bottom of the account in the period being closed. You may also see “b/f” and “c/f,” meaning “brought forward” and “carried forward.” These expressions are common in manual ledger layouts and may still appear in teaching materials or accounting records.

A ledger account records increases and decreases associated with one account, such as Bank, Rent Expense, or Accounts Payable. In a traditional two-sided account, debits are entered on the left and credits on the right. To balance the account, the bookkeeper totals both sides and enters a balancing figure on the side with the smaller total. The same amount is then shown as the opening balance on the appropriate side in the next period.

How balance c/d and balance b/d work

At the close of a period, the balance c/d is the figure needed to make the debit and credit totals equal. It is written on the side with the lower total. In the next period, that amount is written as balance b/d on the opposite side, where it represents the account’s opening balance.

1. Add the debit entries and credit entries in the ledger account.
2. Work out the difference between the two totals.
3. Enter that difference as balance c/d on the side with the smaller total, so both sides have equal totals.
4. In the next period, bring the balance down as balance b/d on the opposite side.

The c/d entry is a balancing step, not a new transaction. The b/d entry is likewise not a fresh receipt or payment: it carries forward the account’s existing position. The underlying balance persists even though its label and position on the page change.

Example: a bank ledger account

Suppose a Bank account has debit entries totalling $5,000 and credit entries totalling $3,200 at the end of a period. The debit side is larger by $1,800. To make the account totals equal, enter balance c/d of $1,800 on the credit side. Both sides then total $5,000.

At the start of the next period, enter balance b/d of $1,800 on the debit side. This reflects the bank balance being carried into the new period. The example assumes the account has a debit balance; the relevant side depends on the account’s actual balance and the bookkeeping convention being used.

• Debit total before balancing: $5,000.
• Credit total before balancing: $3,200.
• Difference and balance c/d: $1,800 on the credit side.
• Opening balance b/d next period: $1,800 on the debit side.

Which side should the balance appear on?

For a typical ledger account, the balancing figure is entered on the side with the smaller total. The brought-down balance then appears on the opposite side in the next period. In the bank example, the debit side is larger, so c/d is on the credit side and b/d is on the debit side.

Do not assume every account will have a debit balance. Asset and expense accounts commonly have debit balances, while liability, equity, and income accounts commonly have credit balances under double-entry bookkeeping. Those are general patterns, not a substitute for checking the actual entries and account structure. If credits exceed debits, the balancing direction reverses.

Also distinguish the balance from the balancing entry. Balance c/d is the figure written to equalise the totals; it does not mean the account has been cleared or that the amount has been paid. Balance b/d shows the carried-forward amount at the start of the following period.

How the terms relate to modern accounting

In accounting software, the same process may happen automatically and the user may see a report showing opening and closing balances instead of c/d and b/d labels. The underlying idea remains: transactions affect an account during a period, and its closing balance becomes the opening balance for the next period when the balance is carried forward.

Not every account is carried forward in the same way. Balance sheet accounts—such as assets, liabilities, and equity—generally retain balances across accounting periods. Revenue and expense accounts are generally closed out as part of period-end procedures, with their results transferred according to the applicable accounting system. The simple c/d-to-b/d illustration is especially useful for learning how a ledger balance is calculated; it does not describe every year-end closing entry.

Common mistakes to avoid

• Calling c/d a transaction: It is a balancing figure, not evidence of a new payment, sale, or purchase.
• Putting b/d on the same side as c/d: In the traditional account format, the amount is brought down on the opposite side.
• Confusing the labels with debit and credit rules: The abbreviations describe when a balance is shown, not the nature of the account.
• Assuming every account carries forward unchanged: Period-end closing procedures can close income and expense accounts rather than carry them forward as ordinary continuing balances.
• Mixing up opening and closing dates: C/d belongs to the period being balanced; b/d is shown at the beginning of the next period.

Frequently Asked Questions

Is balance b/d a debit or a credit?
The abbreviation itself does not specify debit or credit. The balance is placed on the side appropriate to the account’s actual closing position; in the traditional layout, it is brought down opposite the c/d entry.

Is balance c/d an expense or income?
No. It is a ledger balancing entry, not an expense or income transaction. The original transactions determine the account balance.

Why is balance c/d written on the smaller side?
Adding it to the smaller side makes the debit and credit totals equal. It is a mechanical step for closing the ledger account, not a claim that a transaction occurred on that side.

Are b/d and b/f the same?
They are commonly used for the same idea: a balance brought into the next period. Likewise, c/d and c/f commonly refer to carrying a balance to the end of a period. Exact notation can vary by ledger format or teaching convention.

Does balance b/d mean money was received?
No. It means an existing balance has been brought forward. A receipt or payment would be recorded as a transaction, with the appropriate debit and credit entries.

Do accounting programs use these abbreviations?
Some systems or reports may display them, but many show opening and closing balances without traditional ledger abbreviations. The accounting purpose—showing the closing position and carrying it into the next period—is the same.
