Calculators

Each of these implements a formula documented elsewhere on this site, so a published method can be checked rather than taken on trust.

Nothing leaves your browser

Every calculation runs locally in JavaScript. No values are transmitted, stored or logged, and there is no analytics on these pages. They work offline once loaded.

Intended use

These are educational and analytical instruments. They compute the published formulas on values you supply — they do not fetch live market data, and a number produced here is not a recommendation to do anything.

The Moonboard Score calculator is the one that most repays use: entering different inputs makes the caps and step thresholds visible in a way that reading the formula does not. Watching the volume component sit at 15 across almost every realistic input is more convincing than the sentence saying it will.
