A Ledger is the principal book of accounts in accounting. Every financial transaction that is first recorded in the Journal is transferred — or posted — into the Ledger, where it is classified account by account.
💡
Standard Definition of Ledger
"A Ledger is a book containing accounts to which debits and credits are posted from books of original entry (the Journal)."
Every category of transaction gets its own dedicated ledger account. For example:
💵 Cash Account
🛒 Purchase Account
🧾 Sales Account
💡 Electricity Account
👔 Salary Account
🏠 Rent Account
What the Ledger Tells You at a Glance
How much cash the business holds at any point
How much it owes to suppliers (creditors)
How much customers owe the business (debtors)
Total income earned and expenses incurred
The closing balance of every individual account

Frequently Asked Questions — Ledger in Accounting
Quick answers to the most common questions students ask
A ledger is the principal book of accounts in which all financial transactions, originally recorded in the Journal, are classified and posted account by account.
It allows a business to see the balance of every account — cash, sales, purchases, salaries, rent — at any point in time. Without a ledger, preparing financial statements is impossible.
The three main types of ledger are:
General Ledger — the master ledger containing all accounts (assets, liabilities, income, expenses)
Sales Ledger (Debtors Ledger) — tracks amounts owed by credit customers to the business
Purchase Ledger (Creditors Ledger) — tracks amounts the business owes to its suppliers
A T-account is the standard format of a ledger account shaped like the letter "T". It has two sides:
Left side (Debit side / Dr) — records all debit entries: assets increasing, expenses, purchases
Right side (Credit side / Cr) — records all credit entries: liabilities increasing, income, sales
Each side has four columns: Date, Particulars, Journal Folio (JF), and Amount.
Ledger posting is the process of transferring each journal entry to its respective ledger account. Here's how it's done:
Take each journal entry one by one
For the account that was debited in the journal, enter the amount on the debit (left) side of that account's ledger
For the account that was credited in the journal, enter the amount on the credit (right) side of that account's ledger
Write the cross-reference (Journal Folio number) for easy tracing
The key differences between a Journal and a Ledger are:
A Journal is the book of original entry — transactions are recorded chronologically as they happen
A Ledger is the book of secondary entry — transactions are classified by account
Journal recording is called journalizing; ledger recording is called posting
Journal comes first in the accounting process; ledger follows it
The ledger is considered the principal book; the journal is a subsidiary book
Balance c/d (Carried Down) is the closing balance of a ledger account written at the end of an accounting period to make both sides of the T-account equal.
Balance b/d (Brought Down) is the same amount written at the start of the next accounting period on the opposite side, becoming the opening balance. The two are always equal in value.
A General Ledger is the master ledger of a business. It contains every account — assets, liabilities, equity, income, and expenses — in one comprehensive book.
Every financial transaction ultimately finds its place in the General Ledger, making it the most important ledger in any accounting system. The Trial Balance and Final Accounts are prepared from the General Ledger balances.
The ledger is called the principal book of accounts because it is the most important book in accounting. Here's why:
All other books (Journal, Cash Book, etc.) are subsidiary to the ledger
The ledger contains the final classified record of all transactions
All financial statements — Trial Balance, P&L, Balance Sheet — are prepared directly from ledger balances
It is the book that shows the true financial position of every account in the business
