What are the five elements in accounting?

The five elements are assets (what the business owns or is owed), liabilities (what it owes outsiders), owner's equity (what it owes the owner: capital plus profit minus drawings), income (money earned), and expenses (costs used up). Every account belongs to exactly one element, and the element fixes whether an increase is a debit or a credit. Deciding the element correctly is the first step in every entry.

What are the rules of debit and credit?

Debit means the left side of an account and credit the right side; they are positions, not values. Increases in assets, expenses and drawings are recorded as debits, while increases in liabilities, income and capital are recorded as credits. The memory aid DEAD CLIC captures this: Debit for Expenses, Assets and Drawings; Credit for Liabilities, Income and Capital. Every transaction debits and credits equal amounts, so total debits always equal total credits.

A T-account is a ledger account drawn as a T, with the account name across the top, debit entries on the left and credit entries on the right. Each entry shows the date, the name of the other account involved, and the amount. Recording a transaction means entering the same amount as a debit in one account and a credit in another, which is the double entry.

How do you balance off a ledger account?

Total both sides, find the difference, and enter it as the balance carried down (balance c/d) on the smaller side so the two totals agree. Then bring the same figure down on the opposite side below the totals as the balance brought down (balance b/d), the opening balance for the next period. A debit balance b/d means an asset, expense or drawings; a credit balance b/d means a liability, income or capital.

Why do total debits always equal total credits?

Because every transaction is recorded twice, once as a debit and once as an equal credit, the books are kept in balance by design. The same money has two effects: a source and a use. This is the principle that lets the trial balance check the arithmetic of the ledger, since the two columns should add up to the same total when every entry has been posted correctly.

The double entry recording system: N(A)-Level Principles of Accounts (SEAB 7086), covering the five elements and classification, the rules of debit and credit, recording transactions in T-accounts, and balancing off accounts

An N(A)-Level Principles of Accounts (SEAB 7086) overview of the double entry recording system: classifying every account into the five elements, the rules of debit and credit under DEAD CLIC, recording transactions in T-accounts, and balancing off an account to bring down its balance.

What this module trains

Double entry is the engine of N(A)-Level Principles of Accounts (SEAB 7086). Once you can classify an account, apply the rules of debit and credit, record in T-accounts, and balance an account off, almost every later task (the trial balance, the year-end adjustments, the financial statements) becomes a matter of careful, repeated technique. The 7086 papers test this directly, asking you to post named transactions and to balance accounts cleanly, so the goal of this module is to make the mechanics automatic.

This guide links the four dot points of the module, each with its own page and practice. The subject hub is at /sg-n-level/accounting and the syllabus index at /sg-n-level/accounting/syllabus.

Classifying accounts and applying the rules

The five elements and classification dot point sets out the five groups every account belongs to and shows how to decide which one an item is by asking whether it is earned, used up, owned or owed. The element then fixes the rule. The debits and credits dot point states those rules: debit increases Expenses, Assets and Drawings, while credit increases Liabilities, Income and Capital, summarised by DEAD CLIC.

Recording in T-accounts

The recording transactions in T-accounts dot point shows how to enter a transaction in the ledger, with an equal debit in one account and credit in another, each line naming its partner in the details column so the double entry can be traced. A handy summary of the common entries:

Capital introduced: debit bank or cash, credit capital.
Drawings: debit drawings, credit bank, cash or purchases.
Expense paid: debit the expense, credit bank or cash.
Credit purchase: debit purchases, credit the supplier (trade payable).
Credit sale: debit the customer (trade receivable), credit sales.
Returns inwards: debit returns inwards, credit the customer.
Returns outwards: debit the supplier, credit returns outwards.

Balancing off an account

The balancing off accounts dot point shows how to close an account at the period end and carry the balance forward.

Posting transactions and balancing the bank account

step 1: post the opening capital

The owner pays $\text{S\textdollar}20{,}000$ into the business bank account as capital. Debit bank $\text{S\textdollar}20{,}000$ ; credit capital $\text{S\textdollar}20{,}000$ .

step 2: post the payments and receipts

The business pays rent $\text{S\textdollar}1{,}500$ by cheque (debit rent, credit bank $\text{S\textdollar}1{,}500$ ), receives $\text{S\textdollar}4{,}000$ from a cash sale paid into the bank (debit bank, credit sales $\text{S\textdollar}4{,}000$ ), and the owner withdraws $\text{S\textdollar}800$ by cheque (debit drawings, credit bank $\text{S\textdollar}800$ ).

step 3: total each side of the bank account

Debit side of bank: $\text{S\textdollar}20{,}000 + \text{S\textdollar}4{,}000 = \text{S\textdollar}24{,}000$ . Credit side of bank: $\text{S\textdollar}1{,}500 + \text{S\textdollar}800 = \text{S\textdollar}2{,}300$ .

step 4: balance off

Difference $= \text{S\textdollar}24{,}000 - \text{S\textdollar}2{,}300 = \text{S\textdollar}21{,}700$ . Enter balance c/d $\text{S\textdollar}21{,}700$ on the credit (smaller) side so both totals are $\text{S\textdollar}24{,}000$ , then bring down balance b/d $\text{S\textdollar}21{,}700$ on the debit side. A debit balance b/d confirms the bank is an asset of $\text{S\textdollar}21{,}700$ .

The double entry recording system underpins N(A)-Level Principles of Accounts (SEAB 7086). Every account belongs to one of five elements (assets, liabilities, owner's equity, income, expenses), and the element fixes the rule. Under DEAD CLIC, debit increases Expenses, Assets and Drawings, and credit increases Liabilities, Income and Capital. Each transaction is posted to T-accounts as an equal debit and credit, so the books stay in balance: capital introduced is debit bank, credit capital; an expense is debit expense, credit bank; a credit purchase is debit purchases, credit the supplier; a credit sale is debit the customer, credit sales. An account is balanced off by totalling both sides, inserting the balance c/d on the smaller side, and bringing down the balance b/d on the opposite side as the opening figure for the next period.

Check your knowledge

A mix of recall and posting questions across the module. Work each fully, then check against the solutions.

Name the five elements and give one example of each. (5 marks)
State, using DEAD CLIC, which side increases an asset and which side increases a liability. (2 marks)
Give the double entry for paying wages of $\text{S\textdollar}2{,}000$ by cheque. (2 marks)
Give the double entry for a credit sale of goods for $\text{S\textdollar}3{,}500$ to a customer. (2 marks)
A cash account has debit entries totalling $\text{S\textdollar}9{,}000$ and credit entries totalling $\text{S\textdollar}5{,}600$ . Calculate and describe the balance carried down. (3 marks)
Explain why total debits always equal total credits. (2 marks)

Solutions

Q1: Assets (e.g. equipment); liabilities (e.g. a bank loan); owner's equity (e.g. capital); income (e.g. sales); expenses (e.g. rent). Any one valid example per element earns the mark.
Q2: An asset increases on the debit side (the A in DEAD). A liability increases on the credit side (the L in CLIC).
Q3: Debit wages $\text{S\textdollar}2{,}000$ (an expense increases); credit bank $\text{S\textdollar}2{,}000$ (an asset decreases).
Q4: Debit the customer / trade receivable $\text{S\textdollar}3{,}500$ (an asset increases); credit sales $\text{S\textdollar}3{,}500$ (income increases).
Q5: Difference $= \text{S\textdollar}9{,}000 - \text{S\textdollar}5{,}600 = \text{S\textdollar}3{,}400$ . Enter balance c/d $\text{S\textdollar}3{,}400$ on the credit side; bring down balance b/d $\text{S\textdollar}3{,}400$ on the debit side. A debit balance b/d shows cash of $\text{S\textdollar}3{,}400$ held, an asset.
Q6: Every transaction is recorded twice, once as a debit and once as an equal credit. Because each entry has a matching opposite entry of the same amount, the total of all debits must equal the total of all credits.
