Accounting Cycle in Excel: Journal Entries to Trial Balance

An accounting cycle in Excel assignment usually asks students to turn a month of business transactions into journal entries, ledger balances, trial balances, adjusting entries, financial statements, closing entries, and a post-closing trial balance. The hard part is not only knowing the accounting rules. It is also keeping the Excel workbook linked, balanced, and easy to explain in a presentation or viva.

This guide explains how to complete an accounting cycle practice set in Excel without treating any real student case as a copy-paste answer. Use it as a workflow for journal entries, GST, accrual and deferral adjustments, worksheets, income statements, balance sheets, and closing entries.

What This Accounting Cycle Assignment Usually Requires

Accounting cycle practice sets are designed to test whether you understand the full flow of accounting data. OpenStax describes the early accounting cycle as identifying transactions, recording them in a journal, posting them to ledgers, and preparing an unadjusted trial balance. Most student practice sets continue through adjustments, statements, closing entries, and post-closing checks.

In Excel, the assignment may ask for:

• Journal entries for owner investment, purchases, sales, expenses, loans, discounts, GST, and bills.
• Posting to general ledger accounts.
• Unadjusted, adjusted, and post-closing trial balances.
• Accrual and deferral adjustments, such as prepaid insurance, supplies used, depreciation, interest, wages, and unearned revenue.
• A worksheet with trial balance, adjustments, adjusted trial balance, income statement, and balance sheet columns.
• Financial statements: income statement, statement of owner’s equity, and balance sheet.
• Closing entries for revenue, expenses, drawings, and income summary if your course uses that account.
• A short presentation or viva explaining the journal entries and financial statements.

How to Set Up the Excel Workbook

A clean workbook structure prevents most errors. Even if your lecturer gives you a template, the logic usually follows the same order.

Journal Entries With GST, Discounts, and Inventory

The journal is the first place where the accounting logic becomes visible. Each transaction should show the date, account debited, account credited, amount, and a short explanation.

Basic Journal Entry Rule

For example, if the owner contributes cash and equipment, the business receives assets and records owner’s capital. A simplified version might look like this:

Use XX here as a placeholder. Your actual assignment numbers should come from your workbook, not from a public blog post.

GST in Journal Entries

If your course uses Australian GST, read the transaction wording carefully. For GST-registered businesses, tax invoices show GST on taxable sales, and GST credits may be claimed on eligible business purchases when a valid tax invoice is held. If the price is GST-inclusive and GST is 10%, a common classroom calculation is:

For a cash sale, a simplified journal entry may include Cash, Sales Revenue, and GST Payable. For a purchase, it may include Inventory or Expense, GST Receivable, and Cash or Accounts Payable. Always follow the chart of accounts your lecturer provides.

Inventory and Discounts

Inventory transactions often create confusion because the assignment may use perpetual or periodic inventory systems. In a perpetual system, inventory and cost of goods sold are updated as purchases and sales occur. In a periodic system, cost of goods sold is usually determined at period end.

Discounts also depend on wording:

• Cash discount received: reduces the amount paid to the supplier if payment is made within the discount period.
• Cash discount allowed: reduces the amount collected from the customer when the customer pays within the discount period.
• Terms such as 2/20, n/45: mean a 2% discount is available if paid within 20 days; otherwise the net amount is due within 45 days.

Posting to the General Ledger

After journal entries are recorded, the next step is posting to the general ledger. The ledger shows activity by account instead of by date. This is what lets you calculate ending balances for Cash, Accounts Receivable, Inventory, Prepaid Insurance, Equipment, Accumulated Depreciation, Accounts Payable, Loan Payable, Capital, Sales, Expenses, and other accounts.

A practical Excel ledger can use these columns:

• Account number
• Account name
• Date
• Description
• Debit
• Credit
• Running balance
• Journal reference

The ledger is also where early mistakes become visible. If Cash shows a credit balance when it should not, or Sales Revenue appears as a debit balance, go back to the journal entries and check account direction.

Preparing the Unadjusted Trial Balance

The unadjusted trial balance lists all account balances before adjusting entries. OpenStax explains that the trial balance is prepared from the general ledger and helps identify computational errors by checking whether total debits equal total credits.

Common debit-balance accounts include Cash, Accounts Receivable, Inventory, Supplies, Prepaid Insurance, Equipment, Cost of Goods Sold, Rent Expense, Salaries Expense, Insurance Expense, Depreciation Expense, and Utilities Expense. Common credit-balance accounts include Accounts Payable, GST Payable, Loan Payable, Accumulated Depreciation, Unearned Revenue, Owner’s Capital, and Sales Revenue.

If the trial balance does not balance, check these items first:

• A one-sided journal entry where the debit or credit was missed.
• A number entered in the wrong column.
• A transposition error, such as typing 540 instead of 450.
• An account posted to the wrong ledger.
• A formula range that misses one row of the journal.

Adjusting Entries for Accruals and Deferrals

Adjusting entries bring the accounts up to date at the end of the period. AASB’s Conceptual Framework explains that accrual accounting reflects transactions and events in the period in which their effects occur, even when cash receipts or payments happen in a different period. That idea is the reason adjusting entries exist.

Example: Prepaid Insurance Adjustment

If insurance was paid in advance for 18 months, the monthly insurance expense is calculated by dividing the total prepaid amount by 18. At month end, one month is moved from Prepaid Insurance to Insurance Expense.

Example: Supplies Adjustment

Supplies adjustments use the ending physical count or ending balance. If the Supplies account before adjustment is larger than the supplies remaining at month end, the difference is Supplies Expense.

These two examples are common because they test whether you understand deferrals: cash was paid earlier, but the expense should be recorded only when the benefit is used.

Building the Accounting Worksheet

The worksheet is the bridge between the trial balance and the financial statements. Many accounting assignments use a multi-column worksheet with these sections:

• Unadjusted trial balance debit and credit columns.
• Adjustments debit and credit columns.
• Adjusted trial balance debit and credit columns.
• Income statement debit and credit columns.
• Balance sheet debit and credit columns.

The adjusted trial balance should equal the unadjusted trial balance plus or minus the adjustments. The income statement columns should include revenue and expense accounts. The balance sheet columns should include assets, liabilities, and equity accounts.

Use the worksheet as a diagnostic tool. If the adjusted trial balance balances but the balance sheet does not, the issue is probably a classification or net income transfer problem rather than a journal-entry problem.

Income Statement, Equity Statement, and Balance Sheet

Once the adjusted trial balance is complete, financial statements should be straightforward. The key is to separate temporary accounts from permanent accounts.

If the balance sheet does not balance, check whether net income was carried correctly into owner’s equity. Many students correctly prepare the income statement but forget that profit affects equity.

Closing Entries and Post-Closing Trial Balance

Closing entries reset temporary accounts to zero so the next accounting period can begin cleanly. Temporary accounts normally include revenue, expenses, and drawings. Permanent accounts, such as assets, liabilities, and capital, carry forward.

Depending on the course, closing entries may use an Income Summary account. A common classroom sequence is:

1. Close revenue accounts to Income Summary.
2. Close expense accounts to Income Summary.
3. Close Income Summary to Owner’s Capital.
4. Close Drawings to Owner’s Capital.

After closing, the post-closing trial balance should include only permanent accounts. If Sales Revenue, Rent Expense, Salaries Expense, or Drawings still have balances, the closing process is incomplete.

Presentation and Viva Tips

If your assessment includes a short presentation or viva, the lecturer is usually checking whether you understand your own workbook. You do not need to explain every cell. You need to explain the logic.

Suggested 3-5 Slide Structure

Viva Questions to Prepare For

• Why did you debit one account and credit another?
• How does a sale affect the income statement and balance sheet?
• Why is prepaid insurance an asset before it becomes an expense?
• What is the difference between unadjusted and adjusted trial balance?
• Why do closing entries affect revenue and expenses but not cash?
• How does unearned revenue affect liabilities?
• What does the balance sheet prove at the end of the accounting period?

Common Mistakes to Avoid

• Copying the exact assignment online: this creates academic integrity risk and does not help you explain the viva.
• Ignoring GST wording: GST-inclusive and GST-exclusive amounts are not treated the same way.
• Mixing perpetual and periodic inventory methods: use the method specified in your assignment.
• Posting to the wrong ledger account: a balanced journal entry can still be wrong if the account is wrong.
• Changing trial balance numbers manually: fix the journal or ledger source instead of forcing totals to match.
• Forgetting adjustments: prepaid insurance, supplies used, depreciation, accrued interest, unpaid utilities, and unearned revenue commonly appear at month end.
• Leaving revenue and expense accounts open: after closing, temporary accounts should be zero.
• Not linking Excel cells: hard-coded statement numbers can break when a journal entry changes.
