45 entries

Core double-entry rules

Debit side
Left column of a T-account

Debit identifies a posting side; it does not necessarily mean a loss or withdrawal. [1][3]

Credit side
Right column of a T-account

Credit identifies the opposite posting side, not automatically income. [1][3]

Double-entry requirement
Total debits = total credits

Every properly recorded journal entry has offsetting postings of equal total value. [1][3]

Basic accounting equation
Assets = Liabilities + Equity

The equation stays balanced after each journal entry. [1][3]

Expanded equation
Assets = Liabilities + Capital + Revenue − Expenses − Dividends

A teaching model showing how operating activity changes equity. [1][3]

Assets increase
Debit an asset account

A cash receipt increases Cash through a debit posting. [1][3]

Liabilities increase
Credit a liability account

New amounts owed typically increase Accounts Payable by credit. [1][3]

Equity increases
Credit an equity account

A new owner investment usually increases equity by credit. [1][3]

Revenue increases
Credit a revenue account

Revenue recognition increases the revenue account on its normal side. [1][3]

Expense increases
Debit an expense account

Recognized expenses increase on the debit side, normally reducing equity. [1][3]

Check posting and trial balances

Equal debits and credits
Sum of all debit amounts = sum of all credit amounts

An unequal entry is not a valid double-entry journal record. [1][2]

T-account totals
Ending balance = opening balance + increases − decreases

Whether debit or credit increases depends on the account type. [1][2]

Debit-normal account balance
Net debit = debit postings − credit postings

Used for ordinary asset and expense accounts with debit-normal balances. [1][2]

Credit-normal account balance
Net credit = credit postings − debit postings

Used for ordinary liabilities, equity and revenue accounts. [1][2]

Trial balance
List accounts with debit or credit ending balances

The trial balance checks total equality but does not detect every error. [1][2]

Both sides balance, still wrong
A correctly balanced amount can be in the wrong account

Equal totals are necessary but do not prove classification or timing is right. [1][2]

Do not count loan proceeds as sales
Borrowed cash credits a liability, not revenue

Financial statement income differs from every cash receipt. [1][2]

Do not double-count an invoice
Customer payment clears receivable, not revenue

Recognize revenue at earning under accrual accounting. [1][2]

Accrual versus cash
Service billed ≠ cash received

The recorded period depends on accounting basis and transaction facts. [1][2]

Review source documents
Match date, account, amount and explanation

Reconcile entries against invoices, receipts and bank activity before posting. [1][2]
