Here we will learn about percentage profit, including what percentage profit is and how to solve problems involving percentage profit.
There are also percentage profit worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
What is percentage profit?
Percentage profit is writing a profit as a percentage. This makes it easier to compare with other profits.
To do this you need to find the profit and change this into a percentage of the original amount (the cost of the item at the start). Calculating profit is done by finding the difference between the cost price and the selling price.
You can use this formula to calculate the profit percentage,
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100 .
For example, I bought a painting for £200. I sold it for £230. So the profit I have made is £30 as this is the difference between the cost price and the selling price.
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100=\cfrac{30}{200}\times 100=15\%
The percentage profit is 15\%.
The amount of money the item is bought for at the start can be called the cost price (or cost of goods sold).
The amount of money the item is sold for later in the question can be called the sale price or the selling price.
This can be extended into calculating percentage loss. This is when the value has gone down over time (known as depreciation).
\text{Percentage loss}=\cfrac{\text{loss}}{\text{original}}\times 100
This skill is very useful for business owners.

Percentage profit examples
Example 1: calculating percentage profit
Ron bought an antique train set for £130.
He sold it for £215.
Calculate the percentage profit Ron made.
Give your answer to the nearest percent.
- Calculate the difference between the cost price and the selling price.
The difference is,
215-130=85.
2Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage profit by making a fraction and multiplying by 100.
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100=\cfrac{85}{130}\times 100=65.384…
3Write down the final answer.
The percentage profit Ron made is \bf{65\%} to the nearest percent.
Example 2: calculating percentage profit
Ellen buys a house for £210 \ 000. She sells the house for £226 \ 500.
Calculate the percentage profit Ellen makes. Give your answer to 1 decimal place.
Calculate the difference between the cost price and the selling price.
The difference is,
226 \ 500-210 \ 000=16 \ 500.
Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage profit by making a fraction and multiplying by 100.
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100=\cfrac{16 \ 500}{210 \ 000}\times 100=7.857…
Write down the final answer.
The percentage profit Ellen makes is \bf{7.9\%} to 1 decimal place.
Example 3: calculating percentage loss
Diane bought an antique vase for £95.
She sold it for £78.
Calculate the percentage loss Diane made.
Give your answer to 3 significant figures.
Calculate the difference between the cost price and the selling price.
The difference is,
95-78=17.
Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage loss by making a fraction and multiplying by 100.
\text{Percentage loss}=\cfrac{\text{loss}}{\text{original}}\times 100=\cfrac{17}{95}\times 100=17.894…
Write down the final answer.
The percentage loss Diane made is \bf{17.9\%} to 3 significant figures.
Example 4: calculating percentage loss
Rahul bought a van for £16 \ 500.
He sold it for £9 \ 350.
Calculate the percentage loss Rahul made.
Give your answer to 3 significant figures.
Calculate the difference between the cost price and the selling price.
The difference is,
16 \ 500-9 \ 350=7 \ 150.
Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage loss by making a fraction and multiplying by 100.
\text{Percentage loss}=\cfrac{\text{loss}}{\text{original}}\times 100=\cfrac{7 \ 150}{16 \ 500}\times 100=43.333…
Write down the final answer.
The percentage loss Rahul makes is \bf{43.3\%} to 3 significant figures.
Example 5: problem solving
Katie buys a pack of 12 bottles of water for £3.50.
She sells the water at 80p per bottle.
Work out Katie’s percentage profit.
Give your answer to 3 significant figures.
Calculate the difference between the cost price and the selling price.
First you need to calculate the total selling price (or total sales).
12\times 80=960
The total selling price is £9.60
The difference is,
£9.60-£3.50=£6.10 .
Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage profit by making a fraction and multiplying by 100.
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100=\cfrac{6.10}{3.50}\times 100=174.285…
Write down the final answer.
The percentage profit Katie makes is \bf{174\%}.
Example 6: problem solving
Ranjeev buys 20 jackets at £25 each.
He sells 15\% of them for £50 each and half of them for £35. He sells the rest for £12 each.
Work out Ranjeev’s percentage profit or loss.
State clearly if Ranjeev makes a profit or a loss.
Give your answer to 3 significant figures.
Calculate the difference between the cost price and the selling price.
First you need to calculate the total cost price (or cost of goods sold).
20\times \pounds25=\pounds500
Then you need to work out the total selling price (or total sales).
15\% of 20 is 3 jackets, so he sells 3 jackets at £50. He also sells 10 jackets at £35 and 7 jackets at £12.
The total selling price is,
(3\times \pounds50) + (10\times \pounds35) + (7\times \pounds12)=\pounds584.
Ranjeev sells the jackets for more than he bought them for, so he has made a profit.
The difference is,
584-500=84 .
Express the profit (or loss) as a fraction of the original amount and multiply by \bf{100} .
You can find the percentage profit by making a fraction and multiplying by 100.
\text{Percentage profit}=\cfrac{\text{profit}}{\text{original}}\times 100=\cfrac{84}{500}\times 100=16.8
Write down the final answer.
Ranjeev makes a profit and the percentage profit is \bf{16.8\%}.
Common misconceptions
- Always use the original cost price as the denominator
The original cost price is always used as the denominator in the percentage formula for profit.
- Be consistent with pounds and pence
Sometimes questions may give one amount of money in pence (p), and another amount of money in pounds (£). When you calculate the percentage profit (or loss) make sure you use the same type of monetary units in your fraction. Whichever you use will give the same percentage profit.
- Percentage profits can be more than \bf{100}
When calculating percentages for profits, they can be greater than 100\%. For example, if I buy a bottle of water for £0.50 and I sell it for £2, I made £1.50 profit which is 300\% profit. I sold the bottle for 4 times more than I originally bought it for.
