This chapter discusses calculating profit and loss, and the double entry system for recording expenses and revenues. It explains that profit is calculated as revenue minus expenses, and how profit or loss affects the accounting equation and capital. Separate accounts are used for each type of expense and revenue, with expenses recorded as debits and revenues as credits. The chapter also covers how drawings by the business owner are recorded, decreasing capital rather than being an expense.

4. The nature of profit or loss
Profit means the amount by which revenue is
greater than expenses for a set of transactions,
where:
Revenue means the sales value of goods and
services that have been supplied to customers.
Expenses means the cost value of all the
assets that have been used up to obtain these
revenues.

5. Calculating profit
If we supplied goods and services valued for
sale at £100,000 to customers, and the
expenses incurred by us in order to supply
those goods and services amounted to
£70,000, the result would be a profit of
£30,000:
Revenue £100,000
Less expenses (£70,000)
Profit £30,000

6. The effect of profit and loss
on capital
The accounting equation we have used is:
Capital = Assets − Liabilities
When profit has been earned, this increases
capital:
Old capital + Profit = New capital
Or when a loss has been earned, the capital
figure decreases:
Old capital − Loss = New capital

7. Recording expenses
In order to calculate profit, expenses must be
entered into appropriate accounts. A separate
account is opened for each type of expense:
Bank interest account Subscriptions
account
Rent account
Overdraft interest
account
Motor expenses
account
Postages
account
Audit fees account Telephone account Stationery
account
Insurance account General expenses
account
Wages account

8. Debit or credit
Assets and expenses involve expenditure
by the business and are shown as debit
entries because they must ultimately be
paid for.
Revenue is the opposite of expenses and
therefore revenue entries appear on the
credit side of the revenue accounts.

10. Double entries for expenses
and revenues
Rent of £200 is paid in cash:
Debit the rent account with £200
Credit the cash account with £200

and revenues (Continued)
Motor expenses of £355 are paid by
cheque:
Debit the motor expenses account with

Credit the bank account with £355

Credit the commissions received account
with £60

15. Drawings
Money or inventory that the owner takes from
the business for private use is called drawings.
Drawings reduces capital – they are never an
expense of the business.
An increase in drawings is a debit entry in the
drawings account.
The credit entry is against cash or bank if
money was taken from the business, or
purchases if stock was taken.
