Where this widget fits

The embedded calculator includes the same four weight units and tested gold purity choices on every site. Its result is a gross metal benchmark, not an appraisal or an offer to buy.

Install in plain HTML

Choose the options above.
Copy the iframe and paste it into an HTML or code block.
Preview the page at narrow and wide widths, then publish it.

If your site sends a Content Security Policy, allow https://meltoffer.com in frame-src. Increase the iframe height if your layout or text zoom clips its contents.

Install on WordPress

Download the MeltOffer plugin ZIP, install and activate it, then paste the shortcode above into a Shortcode block. WordPress.com users can instead paste the iframe into a supported Custom HTML block.

Install on Shopify

Add a Custom liquid section to the intended page template, paste the iframe, preview the page, and save. Theme section availability varies.

Troubleshooting

If nothing appears, use an HTML or code block; visual editors can remove iframes.
If the widget is cut off, increase only the iframe height.
If it says Delayed, the fallback remains visible and the feed retries automatically every 60 seconds.
If a strict Content Security Policy blocks it, allow https://meltoffer.com in frame-src.

Privacy and data

MeltOffer sets no widget cookies or analytics and does not store calculator inputs. The visitor's browser loads the iframe from MeltOffer and requests current precious-metal prices from Gold API, which receives standard request data including the visitor's IP address. See the privacy policy.

Frequently asked questions

How does the gold calculator widget work?

It converts the entered weight to troy ounces, multiplies by the selected gold purity, then multiplies by the live or editable gold price.

Which gold karats and units are supported?

It supports 24K, 22K, 18K, 14K, 10K, and 9K gold with grams, grains, pennyweight, troy ounces, and avoirdupois ounces.

Can visitors edit the gold price?

Yes. MeltOffer loads a current price when available but keeps the price field visible and editable so visitors can verify another quote or snapshot.

Is the gold calculator widget free?

Yes. It needs no account or API key, and MeltOffer does not store the weights, karats, prices, or results entered in the widget.
