- Paste and publish The widget appears immediately. If you see an empty space instead, your editor has stripped the iframe tag, which the HTML embed guide explains how to work around.
- Adjust the look if you want to Add the parameters in the table below to the iframe URL to change the theme, the accent colour or the height. Nothing needs to be configured on our side.
Customisation options
| Parameter | Values | What it does |
|---|---|---|
theme | auto, light, dark | Default follows the reader's own system setting, so the widget looks right on a dark site and a light one without you choosing. |
accent | Six hex digits, e.g. accent=1A56DB | Recolours the header bar and the primary button to match your brand. |
header | 1 or 0 | Set to 0 to hide the title bar when your page already has a heading above the widget. |
breakdown | 1 or 0 | Set to 0 to hide the calculation breakdown for a more compact block. |
corners | 1 or 0 | Set to 0 for square corners if your design has no rounding anywhere else. |
width | full | Removes the 520px maximum so the widget stretches to its container. |
Parameters are added to the iframe URL as a normal query string, for example
/embed/return-on-equity-calculator.html?theme=dark&accent=1A56DB&header=0. The
widget builder lets you set all of them visually and hands you the finished code.
Why embed the Return on Equity Calculator
Return on equity is one number with three causes, and the DuPont breakdown is how to see them. The widget takes net profit, revenue, assets and equity and returns ROE split into margin, asset turnover and leverage. Share research and finance course pages can show whether a high ROE comes from operations or from debt.
What the widget calculates
Return on equity measures how much profit a company produces from the capital shareholders have left in it. It is the single most useful summary of business quality, and the reason a company can justify trading above book value.
The DuPont decomposition splits it into three parts: profit margin, asset turnover and financial leverage. That matters because a high ROE achieved through debt is a different thing from the same ROE achieved through margin.
The embedded version keeps the inputs and the result. The full Return on Equity Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
