# Cost Price, Sales Price, Mark-Up

**Q: How do you find the cost price if the sales are $216,000 and the mark-up is 50%?**

**"Mark-up" literally means the amount you "mark up" the cost by. This means the amount you increase the cost by to get to the selling price, and is expressed as a percentage of the cost.**

A:

"Mark-up" is basically another way of saying the profit - the difference between the sales price and the cost - but specifically referring to the

**cost**as the starting point or basis of the calculation.

In this example the profit (mark-up) is 50% of the cost price. For the purpose of our calculation, the cost will amount to 100% since it is our starting point or basis.

If we put all this into an equation this simplifies to:

Mark-up / Cost = 50/100

Now let's substitute that first equation above into a general equation for sales, cost and mark-up:

Selling price = Cost + Mark-up (profit)

Selling price = 100% + 50%

Selling price = 150%

In other words, the selling price is 150% of the cost (100%).

Therefore:

Cost = 100/150 X Selling price

= 100/150 x $216,000

= $144,000
