About this project

A small, static tool focused on one job: compute final minus initial with clear sign and units.

Absolute Change Calculator exists to make signed deltas obvious. No accounts, no uploads, and no server-side math.

We pair the on-page tool with short guides so you can confirm homework, budgets, or lab notes without hunting through ads or unrelated finance widgets.

If you spot an issue or want to suggest a topic for the blog, reach out through the contact page.
