# What is the formula to find the markup percent of an item if for example the item is based 700 and you sell it for 3500?

The formula for a rate change or markup percent is:

$p = \frac{N - O}{O} \cdot 100$

#### Explanation:

The formula for a rate change or markup percent is:

$p = \frac{N - O}{O} \cdot 100$

Where:

$p$ is the percentage change - mark up if positive, mark down if negative.

$N$ is the New price

$O$ is the Old price

Solve for this problem gives:

$p = \frac{3500 - 700}{700} \cdot 100$

$p = \frac{2800}{700} \cdot 100$

$p = 4 \cdot 100$

$p = 400$

There is a 400% mark up.
