Foundations Of Accounting And Business

Liabilities - amounts the business owes to other people or organizations. A bank loan and an unpaid supplier invoice are liabilities.

Capital - the owner’s investment in the business, plus profits kept in the business, less amounts taken out by the owner. Capital is also called owner’s equity.

The equation shows the relationship between these parts. If a business has assets of $12,000 and liabilities of $4,000, its capital is $8,000:

$12,000 = $4,000 + $8,000

A transaction may change several figures, but the equation must still balance. For example, when the owner puts $5,000 cash into a new business, cash increases by $5,000 and capital increases by $5,000. When the business buys equipment for cash, equipment increases while cash decreases. Total assets may stay the same, and the equation remains balanced.

Revenue - money earned from selling goods or providing services. A plumbing business earns service revenue when it completes a repair.

Expenses - costs used to run the business and earn revenue. Rent, electricity, wages, fuel, and advertising are common expenses. Expenses reduce profit and therefore reduce capital.

Drawings - cash or other assets taken from the business by the owner for personal use. Drawings reduce capital but are not a business expense.

Debit and credit are the two sides used to record every accounting entry. A debit is the left side of an account, and a credit is the right side. Debit does not automatically mean “increase,” and credit does not automatically mean “decrease.” The effect depends on the type of account.

| Account type | Increase is recorded on | Decrease is recorded on | |---|---|---| | Asset | Debit | Credit | | Expense | Debit | Credit | | Liability | Credit | Debit | | Capital | Credit | Debit | | Revenue | Credit | Debit |

A simple memory aid is that assets and expenses normally have debit balances. Liabilities, capital, and revenue normally have credit balances. Every journal entry must have total debits equal to total credits.

Journal entry - the first formal record of a transaction, showing the accounts affected and the debit and credit amounts.

Ledger account - a separate record for each account, such as Cash, Equipment, Rent Expense, or Sales Revenue. The ledger collects all entries relating to one account.

Trial balance - a list of ledger account balances used to check whether total debits equal total credits. A balanced trial balance does not prove that every transaction is correct, but it helps find recording and addition errors.

The accounting flow is:

Transaction → Journal entry → Ledger accounts → Trial balance → Financial statements

Financial statements - reports that summarize the financial results and position of a business. A basic set includes the income statement, statement of owner’s equity, and balance sheet. The income statement reports revenue, expenses, and profit. The statement of owner’s equity explains changes in capital. The balance sheet reports assets, liabilities, and capital at a particular date.

Consider a business that pays $300 rent in cash. Rent Expense increases, so it is debited. Cash decreases, so it is credited:

| Account | Debit | Credit | |---|---:|---:| | Rent Expense | $300 | | | Cash | | $300 |

The entry records both the cost and the payment. Ask yourself: did an expense increase, and did an asset decrease? If so, the debit-credit choice follows the table.

The key practical takeaway is that debit and credit are not labels for good and bad, or money in and money out. They are a precise left-and-right system that keeps the accounting equation in balance.

Build the Records One Transaction at a Time

A transaction is an event that can be measured in money and affects the business records. Buying a personal lunch is not a business transaction unless the business is responsible for it. Buying ingredients for a catering job is a business transaction because it affects business resources.

Before recording an event, identify the accounts involved. Then decide whether each account increases or decreases. Finally, apply the debit-credit rules. This prevents guessing.

Suppose a business buys a computer for $1,200 on credit. The Computer Equipment asset increases, so it is debited. The amount owed to the supplier increases, so Accounts Payable, a liability, is credited.

| Account | Debit | Credit | |---|---:|---:| | Computer Equipment | $1,200 | | | Accounts Payable | | $1,200 |

The business has not paid cash yet. It owns more equipment and owes more money. Both sides of the accounting equation increase by $1,200.

A cash sale of $700 produces a different entry. Cash, an asset, increases and is debited. Sales Revenue increases and is credited.

| Account | Debit | Credit | |---|---:|---:| | Cash | $700 | | | Sales Revenue | | $700 |

Revenue eventually increases capital through profit. The journal entry does not place the amount directly into the Capital account each time; instead, revenue and expense accounts are later summarized.

A ledger shows the running balance of one account. If Cash begins at zero, the business receives $5,000 from the owner, pays $1,200 for equipment, and receives $700 from a customer, the Cash ledger might look like this:

| Cash ledger | Debit | Credit | Balance | |---|---:|---:|---:| | Owner investment | $5,000 | | $5,000 debit | | Equipment purchase | | $1,200 | $3,800 debit | | Cash sale | $700 | | $4,500 debit |

The ledger makes it easier to see the current balance of Cash. Each account has its own running record.

At the end of a period, the balances are listed in a trial balance. Using the transactions above, the trial balance could include Cash with a $4,500 debit balance, Equipment with a $1,200 debit balance, and Capital with a $5,000 credit balance. If the $700 sale is included, Sales Revenue has a $700 credit balance. The debit total is $5,700, and the credit total is $5,700.

The income statement uses revenue and expenses to calculate profit:

Profit = Revenue - Expenses

If sales revenue is $700 and rent expense is $300, profit is $400. That profit increases the owner’s equity. The balance sheet then shows the final relationship between assets, liabilities, and capital.

A common beginner mistake is recording a loan as revenue. A $2,000 bank loan increases Cash and increases a Loan Payable liability. It does not represent income because the business must repay it. Another common mistake is treating the owner’s investment as revenue. It increases capital, not sales.

Keep the sequence in mind: identify the event, name the accounts, decide whether each account rises or falls, record equal debits and credits, and then update the ledger. This sequence turns a confusing business event into a repeatable process.

Worked Example: From Investment to Financial Statements

A small repair business begins operations with these events:

• The owner invests $6,000 cash. - The business buys tools for $2,000 cash. - It completes repair work for $1,500 cash. - It pays $400 for rent. - It buys supplies costing $300 on credit.

Follow the records carefully.

1. The owner’s investment increases Cash and Capital. Cash is an asset, so it is debited. Capital increases, so it is credited.

| Account | Debit | Credit | |---|---:|---:| | Cash | $6,000 | | | Capital | | $6,000 |

2. The purchase of tools increases Equipment and decreases Cash. Equipment is debited, and Cash is credited.

| Account | Debit | Credit | |---|---:|---:| | Equipment | $2,000 | | | Cash | | $2,000 |

3. The cash repair work increases Cash and Revenue. Cash is debited, and Service Revenue is credited.

| Account | Debit | Credit | |---|---:|---:| | Cash | $1,500 | | | Service Revenue | | $1,500 |

4. Rent is an expense, so Rent Expense is debited. Cash decreases, so Cash is credited.

| Account | Debit | Credit | |---|---:|---:| | Rent Expense | $400 | | | Cash | | $400 |

5. Supplies bought on credit increase Supplies, an asset, and Accounts Payable, a liability. Supplies is debited, and Accounts Payable is credited.

| Account | Debit | Credit | |---|---:|---:| | Supplies | $300 | | | Accounts Payable | | $300 |

Now calculate the ledger balances. Cash is $6,000 minus $2,000 plus $1,500 minus $400, giving $5,100. Equipment is $2,000. Supplies is $300. Accounts Payable is $300. Service Revenue is $1,500, and Rent Expense is $400. Capital is $6,000 before profit is added.

The trial balance is:

| Account | Debit | Credit | |---|---:|---:| | Cash | $5,100 | | | Equipment | $2,000 | | | Supplies | $300 | | | Rent Expense | $400 | | | Accounts Payable | | $300 | | Capital | | $6,000 | | Service Revenue | | $1,500 | | Totals | $7,800 | $7,800 |

The income statement reports revenue of $1,500 and rent expense of $400. Therefore, profit is $1,100.

The statement of owner’s equity starts with capital of $6,000 and adds profit of $1,100. If there are no drawings, ending capital is $7,100.

The balance sheet is:

| Assets | Amount | |---|---:| | Cash | $5,100 | | Equipment | $2,000 | | Supplies | $300 | | Total assets | $7,400 |

| Liabilities and capital | Amount | |---|---:| | Accounts Payable | $300 | | Ending capital | $7,100 | | Total liabilities and capital | $7,400 |

Final result: Total assets of $7,400 equal liabilities of $300 plus ending capital of $7,100. The accounting equation balances.

Notice the path from activity to report. Each event first became a journal entry. The entries were grouped into ledger balances, checked in the trial balance, and then used to prepare financial statements. That path is the foundation of reliable accounting records.

Practice and Check Your Understanding

1. A business receives a $4,000 bank loan. Which accounts are affected, and which side records each increase? Hint: Cash is an asset, and the loan creates a liability. Do not call the loan revenue.

2. A business pays $250 for electricity in cash. Prepare the journal entry. Hint: Electricity Expense increases, while Cash decreases.

3. A business buys a $900 printer for cash. Does total assets increase, decrease, or stay the same immediately after the purchase? Hint: One asset rises while another asset falls.

4. A business has assets of $18,000 and liabilities of $7,500. Calculate capital. Hint: Rearrange the accounting equation: Capital = Assets - Liabilities.

5. Revenue is $2,400 and expenses are $1,650. Calculate profit and explain its effect on capital. Hint: Use Profit = Revenue - Expenses.

Answer Key: The loan entry is Debit Cash $4,000 and Credit Loan Payable $4,000. The electricity entry is Debit Electricity Expense $250 and Credit Cash $250. The printer purchase leaves total assets unchanged because Cash falls by $900 while Equipment rises by $900. Capital is $10,500. Profit is $750, and it increases capital by $750 if there are no drawings.

A final check is useful whenever you prepare an entry: do the debit and credit totals match, and can you explain how the transaction affects the accounting equation? If both answers are clear, the record is likely on the right track. With practice, journal entries stop looking like separate rules and start showing the movement of the business itself.
