Features & Capabilities

PercentDiff is the original multi-result percent calculator for Chrome. It offers two tabs: one for two numbers and one for a number and a percentage, making it easy to compute a wide range of percent-related values.

Mode A covers percent change with options for percent increase/decrease, percent difference, and how Number 1 compares as a percent of Number 2 (and the opposite). Mode B handles percent-of calculations, including percent of X, X plus or minus percent (markup/markdown), and X as a percent of an original number or its increase/decrease. We value user feedback to keep PercentDiff simple and useful.

This is by far a treasure if you are always calculating percentages. No ads, no cunning marketing tactics it is simple and free; deserves every bit of a 5 stars plus rating.

If you work with numbers in any way shape or form, this app belongs in your phone. The developers have widely resisted the foolish idea to tack on unnecessary noise or annoying ads. I would happily pay for this app, and I hope it remains, and it’s current, pristine, amazingly functional form. To the developers, thank you! I hope you introduce away for us to optionally support you… Something similar to Wikipedia.
