The Accounting equation provides the basis for an understanding of the financial situation of the business. However over a time period (week, month, year) a business will make a profit or a loss. This is expressed as the Profit Equation:
This equation forms the basis of the second important accounting document known as the PROFIT and LOSS STATEMENT
Consider this situation. Business owners have invested £30,000 as cash. They have bought equipment for £15,000 (paying in cash). During the month the business has bought (on supplier credit) £7,500 worth of raw materials and paid salaries of £5,500. Goods have been sold for £20,000 (but on credit terms to customers).
The profit equation would look like this:
If this is put together with the accounting equation, we would get the capital increasing by the amount of the profit (£7,000). Liabilities would show what is owed to the supplier (£7,500) and the assets will be made up of the value of the machinery fixed asset (£15,000), the cash balance (£9,500) and the amount owed by the customer (£20,000).
* The cash of £9,500 comes from the £30,000 owners investment less £15,000 spent on machinery and £5,500 on salaries. As yet the customers have not paid and the business has not yet paid suppliers.
The profit equation and accounting equation are clearly linked in that the results of the profit equation over a particular period impact the accounting equation.
Capital changes as a result of profit or loss. The assets (cash) are effected by any sales not yet paid for by customers, likewise liabilities are increased by any suppliers not yet paid.
