This library covers the calculations a South African personal finance audience actually runs into: capital gains and dividend withholding tax, two-pot retirement withdrawals, estate duty, tax-free savings and retirement annuity contributions, inflation, net worth and compound growth, alongside currency conversion and live market data. The tax tools apply current SARS rules rather than a generic international model, which is the part a global widget provider cannot do for you.

Because you embed rather than copy, threshold changes flow through automatically. A static table of tax brackets pasted into a post in 2024 is wrong by 2026 and nobody notices; an embedded calculator is updated at the source.

Every widget is one line of HTML with no sign-up, no API key and no tracking. They set no cookies and load no analytics, so adding one does not create a consent obligation or put a new processor into your privacy policy.

How to embed a financial widget

  1. Copy the code above Use the copy button so nothing is lost to line wrapping. It is a single iframe tag and it does not need anything else.
  2. 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.
  3. 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.
  4. 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

ParameterValuesWhat it does
themeauto, light, darkDefault follows the reader's own system setting, so the widget looks right on a dark site and a light one without you choosing.
accentSix hex digits, e.g. accent=1A56DBRecolours the header bar and the primary button to match your brand.
header1 or 0Set to 0 to hide the title bar when your page already has a heading above the widget.
breakdown1 or 0Set to 0 to hide the calculation breakdown for a more compact block.
corners1 or 0Set to 0 for square corners if your design has no rounding anywhere else.
widthfullRemoves 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/position-size-calculator.html?theme=dark&accent=1A56DB&header=0. The widget builder lets you set all of them visually and hands you the finished code.

What the widgets do not do

This matters more than the feature list, so it is stated plainly. The widgets set no cookies, write nothing to local storage, load no analytics, run no advertising and make no network request once the page has loaded, with the single exception of the live market widgets, which fetch public reference rates and nothing else.

For you as a publisher that means embedding one does not add a third-party data processor to your privacy policy, does not create a consent obligation under POPIA or the GDPR, and does not hand a commercial data broker a view of your readers. For your readers it means whatever they type into a calculator stays in their own browser and disappears when the tab closes.

  • What you may do. Embed any widget on any number of pages and sites, change the theme and accent colour, hide the title bar, and set the width to suit your layout.
  • What is asked in return. Leave the small credit line at the bottom of the widget in place. It is one line of small text and it is how readers find the full version.
  • What is not allowed. Removing the attribution, editing the calculation logic and republishing the result as your own, or presenting the outputs as financial advice.

If the credit line genuinely does not work with your layout, use the contact page rather than stripping it out. There is usually an arrangement that suits both sides.

Frequently asked questions

What counts as a financial widget?

Anything that does a financial calculation or shows financial data inside your page rather than sending the reader elsewhere. In this library that covers currency conversion, tax, retirement, inflation, net worth, investment growth and live market data.

The distinction from a trading widget is audience rather than technology. A tax calculator suits a personal finance site; a pip value calculator does not.

Are the tax calculators specific to South Africa?

Yes, and that is deliberate. The capital gains, dividend withholding, two-pot withdrawal, estate duty, TFSA and retirement annuity calculators all apply current SARS rules and thresholds, which is precisely what a generic international tax calculator cannot do.

If your audience is not South African, the currency, inflation, compound growth and market data widgets are the ones that travel.

How often are the tax rules in the calculators updated?

They are reviewed against each national Budget and updated when thresholds change. Because you are embedding rather than copying, your page gets the update automatically without you editing anything, which is the main advantage of an embed over a static table of rates.

Anything time-sensitive should still carry your own note pointing readers at SARS for confirmation.

Can I use the financial widgets on a client's website?

Yes. Agencies and freelancers can embed them on client sites at no cost, on as many sites as they like. The credit line stays in place on each. There is no separate commercial or agency licence to buy.

Do the widgets give financial advice?

No, and this matters if you publish to a South African audience. Under the FAIS Act, providing personal financial advice requires a licence. These widgets calculate figures from inputs the reader supplies and carry a notice saying they are educational rather than advice. They do not make recommendations.

You should still review how the surrounding text on your own page is framed, since the widget's disclaimer does not cover your editorial.

Will a financial widget hurt my page speed scores?

It should not. Each widget is a small static document with no external fonts, no framework and no tracking, and the iframe is lazily loaded so it is only fetched when a reader scrolls near it. A typical widget is a fraction of the weight of one hero image.
