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/forex-compounding-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 widget calculates
Shows what a fixed percentage gain does to a trading account when it is compounded per trade, per trading day, per week or per month. Enter the start balance, the gain, the number of periods and how much of each period's profit you reinvest, and it returns the ending balance, the total profit, how much compounding added over simple interest, the period at which the account doubles, and a milestone table. The Compound Growth Calculator on this site works in annual rates and years; this one works in the units traders actually think in.
The reality check matters more than the table. One percent a day sounds modest and compounds to about 1,100% a year; no fund, bank or trader produces that over years. The calculator flags any assumption that annualises above 100% so the arithmetic is not mistaken for a forecast.
The embedded version keeps the inputs and the result. The full Forex Compounding Calculator on TradeAnswers adds worked examples, the method behind the numbers and a long FAQ.

Personal finance blogs
Readers can test their own plan on the page, which is what most of them came to do.
Financial education sites
Put the calculator under the explanation so the concept and the number sit together.
