About Calquo

Show the work

Most calculator sites give you a number and stop there. Every Calquo tool page shows the formula it uses, walks through a worked example with real numbers, and flags the edge cases where the naive approach goes wrong — stacked discounts that don't simply add, percent changes that aren't symmetric, the difference between a gigabyte and a gibibyte. If you only need the answer, it's at the top; if you want to understand or check it, the method is right below.

Everything runs in your browser

Every tool is client-side. Nothing you type — loan amounts, body measurements, JSON payloads, passwords — is sent to a server. That makes the tools fast, and it means the developer utilities are safe to use with data you wouldn't paste into a random website. The privacy policy spells this out in full.
