How to add it to your site
- Copy the code Use the copy button in the Embed code box so nothing is lost to line wrapping. It is a single iframe tag and it does not need anything else.
- Open the page you want it on In WordPress add a Custom HTML block, in Wix use the Embed HTML element, in Squarespace use a Code block, and on a hand-built site paste it straight into your HTML.
- 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/dcf-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 Discounted Cash Flow Calculator
Discounted cash flow is the valuation method everyone cites and few readers can run. This widget takes free cash flow, a growth rate, a discount rate and a terminal growth assumption and returns the intrinsic value per share, with the sensitivity to each input visible. Share research blogs covering JSE companies can let readers test their own assumptions against the writer's.
What the widget calculates
A discounted cash flow model values a company as the present value of the cash it will produce. It is the most theoretically sound valuation method and the most sensitive to assumptions, which is the trade-off.
Three inputs decide almost everything: the growth rate, the discount rate, and the terminal growth rate. Change any one by a percentage point and the answer moves substantially, which is why a DCF is best used as a range rather than a number.
The embedded version keeps the inputs and the result. The full Discounted Cash Flow Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
