About Percentage Change Calculator

This extension can be used to calculate the difference in percentage between two values, for example Year 1 revenue compared to Year 2 Revenue. DM Calc has multiple calculators for digital marketers and the YoY/MoM growth calculator is the most used one. Therefore, having an easy to use Chrome extension would make things a lot quicker by not having to go to the website and waiting for the page to load or having to go to Excel to calculate the change by using a formula.
