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/estate-duty-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 Estate Duty Calculator
South African estate duty has an abatement, two rates and deductions that readers rarely see worked through. The widget applies the R3.5 million abatement, the 20 and 25 percent bands and the deductions the reader enters, and shows the duty payable. Estate planning, wills and personal finance sites can replace a dense paragraph with a working example.
What the widget calculates
This calculator works out South African estate duty owed, applying the R3.5 million abatement, then 20% on the dutiable amount up to R30 million and 25% on any amount above that.
Enter your gross estate value, allowable deductions, and abatement type, and the calculator returns the estate duty owed, worth planning for alongside your retirement annuity and other long-term structures.
The embedded version keeps the inputs and the result. The full Estate Duty Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.
Who this widget suits
Tax and accounting blogs
Readers can check their own figures against the current SARS rules where they read about them.
Payroll, HR and small business sites
A working South African tax tool inside a help page saves a support question.
Personal finance sites
A tool with the current year built in is more useful than a table that goes stale.
