Question 1

What is a journal entry?

Accepted Answer

A journal entry is a record of a business transaction in your accounting system. Each entry must have at least one debit and one credit, and total debits must equal total credits. Journal entries are the foundation of double-entry bookkeeping and ensure your books stay balanced.

Question 2

What is the accounting equation?

Accepted Answer

The fundamental accounting equation is: Assets = Liabilities + Equity

Every transaction must maintain this balance. When you record revenue or expenses, they ultimately flow through to equity via Retained Earnings. This calculator helps you visualize how each entry affects this equation.

Question 3

What are debits and credits?

Accepted Answer

Debits and credits are the two sides of every accounting transaction:

• Assets: Increase with Debits, Decrease with Credits
• Liabilities: Increase with Credits, Decrease with Debits
• Equity: Increases with Credits, Decreases with Debits
• Revenue: Increases with Credits, Decreases with Debits
• Expenses: Increase with Debits, Decrease with Credits

Remember: Debits and credits don't mean 'good' or 'bad' - they're just the two sides of the ledger.

Question 4

How do journal entries affect financial statements?

Accepted Answer

Journal entries impact financial statements as follows:

• Balance Sheet Accounts (Assets, Liabilities, Equity): Direct impact on financial position
• Income Statement Accounts (Revenue, Expenses): Impact profitability and ultimately Retained Earnings (Equity)

This calculator shows you both impacts simultaneously, helping you understand the full effect of each transaction.

Question 5

What is a compound journal entry?

Accepted Answer

A compound journal entry has more than two lines (i.e., multiple debits and/or credits). For example, recording a sale with sales tax:

• Debit: Cash $1,070
• Credit: Sales Revenue $1,000
• Credit: Sales Tax Payable $70

Total Debits ($1,070) still equal Total Credits ($1,070).

Question 6

Why must debits equal credits?

Accepted Answer

This is the fundamental rule of double-entry bookkeeping. If debits don't equal credits:

• Your books won't balance
• The accounting equation will be violated
• Financial statements will be incorrect
• You won't be able to close your books

This calculator validates that your entries balance and shows the impact on your financial statements.

Question 7

What are normal balances?

Accepted Answer

Each account type has a 'normal balance' - the side (debit or credit) that increases it:

• Assets: Normal Debit Balance
• Liabilities: Normal Credit Balance
• Equity: Normal Credit Balance
• Revenue: Normal Credit Balance
• Expenses: Normal Debit Balance

Accounts with balances on their 'normal' side are positive. Opposite side entries decrease the account.

Question 8

1. Learning basic accounting - See how entries affect statements
2. Training new bookkeepers - Validate their understanding
