The cost price of a product is the actual amount that it costs to purchase or produce it. This figure is important to businesses as it can be used to calculate the selling price, which is the amount that the customer pays for the product. Knowing how to calculate the cost price from the selling price and the mark-up is an important skill for any business person to have.

## Calculating Cost Price

The cost price of a product can be calculated using the selling price and the mark-up. The mark-up is the amount that is added to the cost price to get the selling price. This is usually expressed as a percentage, and can be calculated using the following formula:

Mark-up = (Selling Price – Cost Price) / Cost Price

Once the mark-up has been calculated, the cost price can be calculated using the following formula:

Cost Price = Selling Price / (1 + Mark-up)

## Understanding Mark-up

Mark-up is a crucial concept for businesses to understand. It is the amount that is added to the cost price to get the selling price. The mark-up can be expressed as a percentage or as a fraction of the cost price. For example, if the cost price of a product is $10 and the mark-up is 50%, then the selling price would be $15.

The mark-up is important for businesses as it helps them to determine the selling price of their products. It also helps them to make sure that they are making a profit on the products they are selling.

Calculating the cost price from the selling price and the mark-up is an important skill for any business person to have. Understanding the concept of mark-up is equally important, as it is the amount that is added to the cost price to get the selling price. By using the formulas provided, business owners can easily calculate the cost price and mark-up of their products.
