Enter the number of clicks and the number of opens into the Click to Open Rate Calculator. The calculator will evaluate the Click to Open Rate.

## Click to Open Rate Formula

The following two example problems outline the steps and information needed to calculate the Click to Open Rate.

COR = C / O * 100
• Where COR is the Click to Open Rate (%)
• C is the number of clicks
• O is the number of opens

To calculate the click to open rate, divide the number of clicks by the number of opens, then multiply by 100.

## How to Calculate Click to Open Rate?

The following example problems outline how to calculate Click to Open Rate.

Example Problem #1:

1. First, determine the number of clicks.
• The number of clicks is given as: 500.
2. Next, determine the number of opens.
