About CalcMyCoin

CalcMyCoin exists because crypto math kept getting answered badly: calculators buried inside exchanges that want your signup, blog posts with formulas but no tool, and tools with results but no formula. We build the third thing properly: one page per question, the calculator at the top, the math underneath.

How it is built

Every calculator is plain client-side JavaScript. Your inputs never reach a server, which is not a slogan but an architecture: there is no backend that could store them. The one optional network call any tool makes is fetching a public coin price from CoinGecko when you press the price button.

Who is behind it

A small independent team that has been in crypto since the 2017 cycle, building trading tooling and content sites. We use these calculators ourselves, which is why the fee fields default to on and the disclaimers are honest.

Accuracy

Formulas are documented on each page and centrally on the methodology page. Spot an error, tell us via the contact page and we will fix it and note the change in updates.
