About Us
Kalkoro focuses on a single question: how do you reach the correct answer to a calculation as quickly as possible? We bring hundreds of calculators together under one roof with a clean, fast interface.
How we work
- Calculations run on your device — the values you enter are not sent to our servers.
- Tax brackets, ceilings and tariffs are kept as versioned period data; you always see which period your result was computed with.
- Every regulation-based tool is verified against official sources and known examples, backed by hundreds of automated tests.
- No account required: every tool works fully as a guest. Signing up only syncs your favorites and history across devices.
Who builds it?
Kalkoro is developed in Istanbul by Teknolojig Bilişim Teknolojileri A.Ş.. You can always reach us at info@kalkoro.com.
Our calculation method, parameter sources and correction process are described openly on the "How we calculate" page; the "About this page" block at the bottom of every tool links to it.
