This topic is related to Suspense Account. If you realized that some errors will/will not have an effect on the result of your net profit, you will be required to make adjustments in order to correct the errors and recalculate the new net profit. This is a hard topic, not as easy as you think it is. People should identify whether the errors will cause an increase or decrease in net profit through logical reasoning and most people cannot do that quickly and correctly.
In order to ace this, you should categorize errors as:
1) errors that do affect the net profit and
2) errors that do not affect the net profit.
Now that’s done but how does one identify whether or not the errors affect the profit or not?
Pretty simple. If you guys remember income statement, picture the whole diagram and denote everything into an equation approach, you will arrive at:
Sales – (Cost of Goods Sold) = Gross Profit where
Cost of Goods Sold = Opening Inventory + Purchases – Closing Inventory (in the Trading Account) and that
Net Profit = Gross Profit – Expenses + Income (in the Profit and Loss Account).
SO, reorganizing the Net Profit as the subject of the FORMULA, you get
NET PROFIT = Sales – (Opening Inventory + Purchases – Closing Inventory) – Expenses + Income
!!! Please note to expand the bracket by multiplying with -1 (Do not just throw the bracket! Expand them like a mathematician!)
Finally we have NET PROFIT =
Sales – Opening Inventory – Purchases + Closing Inventory – Expenses + Income
So the conclusion, anything that deals with changing the sales, opening inventory, purchases, closing inventory, expenses and income values will cause a change in net profit. And anything outside these six variables will not change the value of net profit.
So now, how do we determine whether the errors will increase or decrease the net profit?
For illustration purposes, assume
Sales = $ 10,000, Opening Inventory = $ 2,000, Purchases = $ 5,000, Closing Inventory = #3,000, Expenses = 2,500 and no Income.
Net Profit = 10,000 – 2,000 -5,000 + 3,000 -2,500 = $3,500
If you have two errors, sales are undercast (under-reported) by $1,000 and rent are overcast (over-reported) by $ 500.
To correct the error for sales, Sales will be increased by $1,000 to $ 11,000.
Then you new Net Profit (ignoring rental error) = $ 11,000 – 2,000 – 5,000 + 3,000 – 2,500 = $ 4,500
You see that there is an increase in net profit of $ 1,000.
Now, for the rental error, this affect the expenses, expenses will be reduced by $ 500 to $ 2,000.
The new Net Profit (ignoring sales error) = $ 10,000 – 2,000 – 5,000 + 3,000 – 2,000 = $4,000
You see that there is an increase in net profit of $ 500.
So what will be the adjusted net profit? Adjusted net profit will be the old net profit $3,500 plus all the adjustments, the $1,000 and $500.
So $3,500 + $1000 +$500 = $ 5,000 or alternatively you could amend all the values using the equation approach,
Adjusted net profit (combined errors) = $ 11,000 – 2,000 – 5,000 +3,000 -2,000 = $5,000
Let’s say you dislike going through all this calculation, can we derive something from the equation approach? Yes, you can and here goes!
Increase in sales = Increase in net profit (so addition to existing net profit)
Increase in opening stock = Decrease in net profit (so subtraction to existing net profit)
Increase in purchases = Decrease in net profit (so subtraction to existing net profit)
Increase in closing stock = Increase in net profit (so addition to existing net profit)
Increase in expenses = Decrease in net profit (so subtraction to existing net profit)
Increase in gains = Increase in net profit (so addition to existing net profit)
For the reverse, everything is reversed too. Headache? Look at the equation below again.
NET PROFIT =
Sales – Opening Inventory – Purchases + Closing Inventory – Expenses + Income
There are three (+) positive sign, the sales, closing inventory and income. Increase in these three values increase the net profit and likewise.
There are three (-) negative sign, the opening inventory, purchases and expenses. Increase in these three values decreases the net profit and likewise.
Easy? Super easy man!
You can try to experiment on your own with
Sales = $ 10,000, Opening Inventory= $ 2,000, Purchases = $ 5,000, Closing Inventory = $ 3,000, Expenses = $ 2,500 and no Income. Increasing and decreasing the values as you wish. Try treating Income = $ 0.
