1. Ledger — Meaning and Importance
The Ledger is the principal/main book of accounts. It is also called the Book of Final Entry or Book of Secondary Entry. It contains individual accounts for every item (assets, liabilities, capital, incomes, expenses).
- All Journal entries are transferred (posted) to the respective Ledger accounts.
- Each ledger account is maintained in T-Form — Debit (Dr.) side on the LEFT, Credit (Cr.) side on the RIGHT.
- The collection of all ledger accounts is called the Ledger or General Ledger.
2. Posting Rules
- When an account is Debited in Journal → enter on the LEFT (Dr.) side of that account in Ledger, and write "To [other account]" in Particulars.
- When an account is Credited in Journal → enter on the RIGHT (Cr.) side of that account in Ledger, and write "By [other account]" in Particulars.
- For Cash Book transactions, separate posting is NOT needed since the Cash Book itself serves as the ledger for cash/bank accounts.
In Journal: "Dr." written first, "Cr." indented.
3. Balancing the Ledger
At the end of an accounting period, each ledger account is balanced (closed for the period):
- Total both the Dr. and Cr. sides.
- Write the higher total on BOTH sides.
- The difference is the Balance — placed on the SHORTER side.
- If Dr. total > Cr. total → Debit Balance ("To Balance c/d" on Cr. side; "By Balance b/d" on Dr. side next period).
- If Cr. total > Dr. total → Credit Balance ("By Balance c/d" on Dr. side).
| Account Type | Normal Balance | Example |
|---|---|---|
| Asset Accounts | Debit Balance | Cash A/c, Machinery A/c |
| Liability Accounts | Credit Balance | Creditors A/c, Loan A/c |
| Capital Account | Credit Balance | Capital A/c |
| Expense/Loss Accounts | Debit Balance | Salary A/c, Rent A/c |
| Revenue/Income Accounts | Credit Balance | Sales A/c, Commission Received |
4. Trial Balance
A Trial Balance is a statement prepared at the end of the accounting period, listing all ledger account balances (or totals) in two columns — Debit and Credit — to check arithmetic accuracy.
Methods of Preparing Trial Balance
| Method | What is Listed | Feature |
|---|---|---|
| Total Method | Total of Dr. and Cr. sides of each account | Both totals (gross) are shown; more cumbersome |
| Balance Method | Net balance (Dr. or Cr.) of each account | Most common; directly useful for Balance Sheet |
| Combined Method | Both totals AND balance | Used in some advanced accounting systems |
5. Errors and Trial Balance
A Trial Balance that agrees does NOT guarantee that all entries are correct. There are two classes of errors:
Errors that DO NOT affect Trial Balance agreement (Errors of Double Effect):
- Error of Omission: A transaction completely left out — both Dr. and Cr. omitted equally.
- Error of Commission: Posted to wrong account but same side (e.g., Mohan's A/c debited instead of Sohan's A/c).
- Error of Principle: Incorrect classification (e.g., treating capital expenditure as revenue).
- Compensating Errors: Two errors that cancel each other out.
Errors that DO affect Trial Balance (Single-Effect Errors):
- Posting on wrong side (Dr. instead of Cr.).
- Wrong amount posted to one side only.
- Omitting to post one side of an entry.
- Wrong totalling of a subsidiary book.
