Assets, liabilities and owner’s equity

0:00A business can have valuable equipment and money in the bank, yet still owe a supplier for goods. Looking at its possessions alone does not reveal how much belongs to the owner. The accounting equation connects these resources with the claims against them. By the end, you will understand why it balances and how transactions change it. We will use one small business, Maya’s Repairs, throughout this video. Maya owns the business, but its accounting records keep her personal affairs separate.

0:24Under the business entity concept, Maya and her repair shop are treated as two separate parties. So the money Maya puts into the business is recorded as capital. The business owes that amount to Maya. Assets are resources owned by or controlled by the business that bring future benefit. For Maya’s Repairs, these include equipment, inventory, bank and cash. Premises and motor vehicles are other common examples. An item belongs in the business records when it is a business resource, rather than Maya’s personal possession.

0:55Trade receivables are amounts owed by credit customers who have not yet paid for goods or services. They are assets because the business expects to receive payment later. Inventory means goods held for resale. These examples show that business resources include more than physical objects or money already received. Liabilities are amounts the business owes to others. Examples include a bank loan, a bank overdraft and trade payables. Trade payables are amounts owed to suppliers for goods or services purchased on credit.

1:21Buying on credit means receiving something now and agreeing to pay for it later. Owner’s equity, also called capital, is the owner’s investment in the business, or the amount the business owes the owner. It represents the owner’s claim after liabilities are deducted from assets. Unlike a supplier’s claim, its value can change as the business earns profit or makes a loss. It is not necessarily money available for immediate withdrawal.

1:45The accounting equation states that assets equal liabilities plus owner’s equity. The left side describes the resources of the business. On the right, we identify the claims against those resources. We are looking at the same financial position from two different directions, so both sides must agree. Imagine removing everything owed to outsiders from the value of the business resources. What remains is the owner’s equity. That explains the rearrangement: owner’s equity equals assets minus liabilities.

2:13Similarly, liabilities equal assets minus owner’s equity, because removing the owner’s claim leaves the amount owed to others. These relationships help us find missing figures without guessing where a number belongs. Start by identifying the resources, the amounts owed to outsiders and the owner’s claim. Then choose the version that leaves the missing category on its own. We will calculate each category using separate snapshots of Maya’s Repairs.

Calculating missing equation figures

2:37Suppose Maya’s Repairs has liabilities of two thousand three hundred dollars and owner’s equity of seven thousand four hundred dollars. Both claims must be supported by the business resources. Add two thousand three hundred dollars to seven thousand four hundred dollars. Assets are nine thousand seven hundred dollars, which equals the combined claims on the other side. In another snapshot, assets are fifteen thousand six hundred dollars and liabilities are four thousand two hundred dollars.

3:01The owner’s claim is the amount remaining after the outside obligations are deducted. Subtract four thousand two hundred dollars from fifteen thousand six hundred dollars. Owner’s equity is eleven thousand four hundred dollars, and adding liabilities restores assets of fifteen thousand six hundred dollars. For our final missing figure, assets are eighteen thousand eight hundred dollars and owner’s equity is thirteen thousand five hundred dollars. Subtract the owner’s claim from the resources to find the outside claims.

3:26Eighteen thousand eight hundred dollars minus thirteen thousand five hundred dollars gives liabilities of five thousand three hundred dollars. Adding those liabilities to equity restores eighteen thousand eight hundred dollars.

Tracking transactions in the equation

3:38The equation also lets us follow transactions as they happen. For this running example, Maya’s Repairs starts with no resources or claims. We will record each transaction in a table and carry its effects into the next row. Each row shows the position after that transaction, rather than just the amount of the change. Maya pays six thousand dollars into the business bank account as capital. Bank becomes six thousand dollars, while equipment and inventory are both zero dollars.

4:03Total assets are therefore six thousand dollars, and liabilities remain zero dollars. Owner’s equity becomes six thousand dollars, so six thousand dollars equals zero dollars plus six thousand dollars. The business buys equipment for two thousand dollars by bank transfer. Bank falls to four thousand dollars, and equipment rises to two thousand dollars. Inventory remains zero dollars, so total assets stay at six thousand dollars. Liabilities are still zero dollars and equity remains six thousand dollars, which keeps both sides equal.

4:33This purchase changes the composition of assets rather than their total value. Money has been exchanged for equipment that the business now owns. Maya has neither invested more capital nor withdrawn any resources. Buying equipment therefore leaves her claim unchanged in this example. Next, Maya’s Repairs buys inventory for resale on credit for one thousand five hundred dollars. Bank remains four thousand dollars, equipment remains two thousand dollars, and inventory becomes one thousand five hundred dollars.

5:00Total assets rise to seven thousand five hundred dollars. Liabilities become one thousand five hundred dollars, while equity stays at six thousand dollars, so both sides equal seven thousand five hundred dollars. The supplier then receives a payment of five hundred dollars from the business bank account. Bank falls to three thousand five hundred dollars, while equipment remains two thousand dollars and inventory remains one thousand five hundred dollars. Total assets become seven thousand dollars, and liabilities fall to one thousand dollars.

5:28Equity stays at six thousand dollars, so seven thousand dollars equals one thousand dollars plus six thousand dollars. Paying the supplier reduces a resource and an obligation by the same amount. The inventory is still owned by the business after payment. Its purchase was already reflected when the goods arrived on credit. This payment settles part of that existing obligation rather than creating another inventory purchase. Drawings are money or other assets taken from the business by the owner for personal use.

5:54Maya now withdraws eight hundred dollars from the business bank account for private spending. Bank falls to two thousand seven hundred dollars, while equipment stays at two thousand dollars and inventory at one thousand five hundred dollars. Total assets become six thousand two hundred dollars. Liabilities remain one thousand dollars because Maya’s withdrawal does not settle the supplier’s claim. Owner’s equity falls by eight hundred dollars to five thousand two hundred dollars.

6:17Adding one thousand dollars and five thousand two hundred dollars gives six thousand two hundred dollars. This matches total assets, so the equation still balances. Profit increases owner’s equity because the business has earned more for its owner. A loss reduces that claim, and drawings also reduce it. However, drawings are personal withdrawals rather than business expenses. So they reduce owner’s equity, but they are never deducted when calculating profit for the year.

Exam application and recap

6:43A common examination mistake is to treat capital as the bank balance. Capital represents the owner’s claim across all business resources after liabilities are deducted. In our table, some of Maya’s investment became equipment and inventory. Another important distinction is that an owner’s investment increases equity, whereas a bank loan increases liabilities. When applying the equation, identify everything affected before deciding whether total assets change. An exchange between assets can leave the total unchanged.

7:10Purchasing on credit increases resources and obligations together, while paying a trade payable reduces both. Drawings reduce assets and owner’s equity because resources leave for the owner’s private use. Paper one can test these relationships through multiple choice, while Paper two can ask for calculations or explanations in structured questions. Calculate means work out from given figures, so show the substitution and arithmetic. Explain requires reasons that show why or how something happens.

7:38A definition should give the precise meaning, rather than just an example. Consider this question: explain the effect on the accounting equation when Maya’s Repairs buys equipment by bank transfer. Bank decreases by the purchase price. Equipment increases by the same amount, so total assets remain unchanged. Liabilities and owner’s equity are unaffected because the business exchanges one asset for another. The accounting equation connects assets, liabilities and owner’s equity through one balanced relationship.

8:06Resources equal the claims of outsiders plus the owner’s claim. Rearranging that relationship finds missing figures, while tracing transactions explains changes in the financial position. Always identify what increases or decreases, then check that both sides still agree.
