About this project

We built the Percentage Increase Calculator for people who need trustworthy math in a hurry. Students, analysts, founders, and curious shoppers all land here with the same ask: what changed in percent terms?

The interface follows a magazine cover rhythm on the home page, then moves you quickly to the tool. We keep copy in JSON so writers can evolve tone without touching templates.

Accessibility, contrast, and schema parity matter here. If something feels off on your device, use the contact page and we will triage it like a host would.
