Lesson Content/Board Summary

PRINCIPLES AND PRACTICE OF DOUBLE ENTRY

Meaning of Double Entry

Double entry is an accounting system where every financial transaction has two effects, a debit and a credit, of equal value. This system ensures that for every debit, there is a corresponding credit, maintaining the accounting equation (Assets = Liabilities + Equity).

Principles of Double Entry

The core principles of double entry accounting are:

Every transaction affects at least two accounts.
For every debit entry, there must be an equal and corresponding credit entry.
The total of all debits must always equal the total of all credits.

Rules of Double Entry

The rules of double entry are often categorized based on the type of account involved:

Personal Accounts (persons, firms, companies):
- Debit the receiver.
- Credit the giver.
Real Accounts (assets and properties):
- Debit what comes in.
- Credit what goes out.
Nominal Accounts (expenses, losses, incomes, gains):
- Debit all expenses and losses.
- Credit all incomes and gains.

Meaning of Ordinary Cash Book

An ordinary cash book is a book of original entry and a ledger account used to record all cash receipts and cash payments. It has two sides: a debit side for cash received and a credit side for cash paid out. It helps in tracking the cash balance of a business.

Format of Ordinary Cash Book

The ordinary cash book has two sides, debit and credit, each with specific columns. The format includes:

Debit Side (Receipts):
- Date
- Particulars (details of the transaction)
- Folio (ledger reference)
- Amount (cash received)
Credit Side (Payments):
- Date
- Particulars (details of the transaction)
- Folio (ledger reference)
- Amount (cash paid out)

A simplified representation of the format:

Ordinary Cash Book

Debit Side (Receipts)				Credit Side (Payments)
Date	Particulars	Folio	Amount (₦)	Date	Particulars	Folio	Amount (₦)

Preparation of Ordinary Cash Book

To prepare an ordinary cash book, follow these steps:

Draw the cash book format with debit and credit sides.
Record all cash receipts on the debit side, noting the date, particulars (source of cash), and amount.
Record all cash payments on the credit side, noting the date, particulars (purpose of payment), and amount.
Balance the cash book by finding the difference between the total debits and total credits.
If debits are greater than credits, there is a debit balance (cash in hand).
Carry down the balance to the next period.
