Example: 20% of 250 = 250 × 20 ÷ 100 = 50.
Example: if you buy an item for 200 and sell it for 250, your profit is 50, which is 25%.
Example: an item priced at 1,000 with a 15% discount has a discount of 150 and a final price of 850.
Multiply the number by the percentage and divide by 100. For example, 20% of 250 is 250 × 20 ÷ 100 = 50.
In this tool the percentage is based on the cost price. The profit is divided by the cost price and multiplied by 100.
First work out the discount amount as the discount percentage of the original price, then subtract it from the original price.
