FAQs (Frequently Asked Questions)
1. How do you calculate percentage change?
Percentage change is calculated with the formula: `((New Value - Original Value) / Original Value) * 100`. Our tool automates this. You just input the 'From' (original) and 'to' (new) values, and it does the rest, even showing if it's an increase (+) or decrease (-).
2. What if I enter a non-numeric value?
The input fields are set to accept numbers only. If you manage to input invalid text, the calculator's JavaScript will treat it as '0' or show an error, ensuring the calculations don't break. For best results, please only enter numbers.
3. Is this tool free to use?
Yes, this tool is completely free. It runs entirely in your web browser, and we do not store any of the data you enter. It's designed to be a helpful resource for you and your blog's visitors.
4. Will this slow down my Blogger site?
Not at all. The code is highly optimized and self-contained. It loads quickly and all calculations happen on the user's device, not your server. It has a minimal footprint and will not impact your site's performance.
5. How is a percentage decrease shown?
In the "Percentage Change" calculator, if the 'to' value is smaller than the 'From' value, the result will automatically be displayed with a minus sign (-) to clearly indicate a decrease (e.g., -15%).
