About

A small tool for recurring household decisions.

Restock Math exists to answer a narrow question: what does each useful unit cost? The site uses structured records and deterministic calculations, with automation handling routine checks and a human approving publication.

Commercial disclosure

Corrections

Retail prices and package sizes change. Verify the retailer page before purchasing. Records that fail automated checks are removed from rankings until reviewed.
