About Percentage Point Calculator

We built a focused utility for a common reporting mistake: mixing up points and percent change.

The site is static on purpose. There is no account system, no server round trip for the math, and no tracking layer required to use the calculator.

The interface is designed like a small control center: high contrast hierarchy, modular tiles, and a calculator panel that stays easy to scan on a phone.

If you spot an edge case that should be called out in the copy, use the contact page. We keep requests scoped to clarity and correctness, not bespoke data processing.
