User-entered inputs first
The first release of the site uses user-entered values instead of automated market data feeds.
This keeps the tools easier to verify because each result can be traced directly to the numbers entered by the user.
Formula transparency
Each calculator page includes a short formula guide and a scenario explanation so users can understand the intended interpretation of the outputs.
Where possible, the pages expose derived metrics such as break-even price, projected gain, or percentage change in plain language.
Rounding rules
Amounts and percentages are generally presented with up to three decimal places without forcing trailing zeros.
Share quantities are treated as integers, and the grid calculator applies board-lot style rounding when it estimates executable share counts.
Model limitations
The tools are intentionally simplified. Depending on the page, they may exclude taxes, slippage, dividend timing, FX costs, corporate actions, or path-dependent return behavior.
Users should read the on-page disclaimer and treat results as planning references rather than exact forecasts.
