1.1.1The fundamental question and the fundamental equation
As mentioned earlier, the original purpose of accounting was to inform business owners about their financial performance. But what does financial performance mean? Financial performance means the value of the business that is available to the owner, which is usually money that can be spent by the owner, but it can also be in other forms of goods or rights.
But our businessman has more than just a bank account with a positive balance. Let us assume he provides consulting services for companies. For that he needs some equipment, so he buys some assets for example a computer, a mobile phone, and some software. He rents office space and buys some office furniture. Thus, he spends money and acquires other assets that have value. Perhaps one of his suppliers does not ask for cash payment but offers credit, which the businessman takes advantage of. Then he acquires some asset; he does not lose money (at least for now) but he does have a liability: He will eventually have to pay a certain amount of money to settle his purchase.
This leads to the following fundamental accounting equation:2
Net Assets = Assets ā Liabilities.
The value that is available for the businessman are the net assets, that is all valuable items the business owns minus all obligations for future payments the business incurs. In accounting, net assets are also called (ownerās) equity:
Equity = Assets ā Liabilities or Assets = Equity + Liabilities.
This fundamental equation gives the first important information to the owner of the business, and it must be satisfied all the time at a specific point in time; we return to this point later on.
Another important piece of information is change in equity. To analyse a change in equity, we need to look at a specific time period: At the beginning of this period there is a starting value, and at the end there is an ending value. If the ending value is higher than the starting value, equity increased; this is called profit because the value of the business increased. If the ending value is lower than the starting value, then equity decreased; this is called a loss.3
Example
The aforementioned businessman starts his business with ā¬10,000 in cash. He purchases office equipment for a total of ā¬6,000. Part of it, ā¬4,000, he pays in cash; part of it, ā¬2,000 he buys on credit. He provides services for ā¬24,000, which is paid in cash, and has current expenses for rent and other items of ā¬8,000, which he pays for in cash as well.
What is his financial position at the end of this period?
At the beginning, his equity stake in the business comes to ā¬10,000.
Thus, we sum up his assets as follows (all figures in Euros):
Cash at the beginning | 10,000 |
ā purchases in cash | ā 4,000 |
ā current expenses | ā 8,000 |
+ cash from services | 24,000 |
= cash at end | 22,000 |
+ purchased assets | 6,000 |
= total assets | 28,000 |
Applying the fundamental accounting equation
Equity = Assets ā Liabilities = 28,000 ā 2,000 = 26,000
we see that his equity (the value of his business) increased from ā¬10,000 to ā¬26,000, i.e. he made a profit of ā¬16,000.
1.1.2Financial and managerial accounting
The original idea of accounting was to inform the owner of a business about the businessās financial situation. In 1494, Luca Pacioli, a Franciscan monk, made the first comprehensive presentation of double-entry bookkeeping. This is the method still used today in the vast majority of companies. In the following sixteenth and seventeenth centuries, it became common practice for businessmen to account for their transactions and to prepare financial statements, usually at the end of the year.4
The wider use and better understanding of accounting and, as a consequence, oneās own financial position allowed people to develop more complex business models: Selling and purchasing on credit, the use of different forms of credit and insurance and, in...
