Does the gold and silver calculator show real-time prices?

Yes. GG Metal Price Calculator automatically retrieves international gold and silver market prices and updates them using smart caching for high performance.

No. When a request is submitted, the plugin recalculates all values server-side, verifying karat/fineness, weight, and total price.

How does the “Lock the Price” button work?

After calculating the price, customers can lock the quote and contact you via WhatsApp, email through an on-site modal, or by printing/saving a PDF summary. The feature can also be disabled.

Sources of gold and silver market prices

The prices displayed by GG Metal Price Calculator are based on international market data used as reference for the spot price of gold and silver.

The plugin retrieves the spot price per ounce in US dollars (USD) from international financial data providers and automatically converts it to euro per gram (€/g).

Gold (XAU) and Silver (XAG) spot prices: international market feeds with automatic fallback
USD/EUR exchange rate: official reference from the European Central Bank (ECB)

All values are:

converted from troy ounce to gram
converted from USD to EUR
automatically updated using smart caching

The final price displayed in the calculator takes into account:

real purity coefficients (karat or fineness)
custom spreads configured by the site administrator

Prices are provided for informational and indicative purposes only and do not constitute an official or binding quotation. The final price may vary based on market conditions, physical inspection of the material, and the operator’s commercial policies.

Availability of price data sources

The gold and silver prices displayed by GG Metal Price Calculator depend on the availability of external market data providers used as reference sources.

In the event of temporary unavailability, technical limitations, API changes, or service discontinuation by one or more providers, the plugin is designed to:

automatically attempt alternative data sources when available
use cached values for short periods
temporarily disable calculations to avoid displaying unreliable data

When market prices are not available, the calculator may display an informational message or be temporarily inactive, without affecting the overall functionality of the website.

Price data sources may be updated, replaced, or modified over time to ensure the highest possible reliability, without any obligation to maintain a specific provider.

All displayed values are provided for informational purposes only and do not constitute any contractual commitment or official quotation.

Settings & Configuration (WordPress Admin Panel)

GG Metal Price Calculator includes a complete
WordPress settings panel, designed for jewelers, gold buyers,
and silver buyers who want to manage spreads, visible karats,
and the “Lock the Price” CTA in a simple and professional way.

1) Gold spreads (€/g) by karat

You can set a custom spread (€/g) for each gold karat.
The spread is subtracted from the pure value calculated from live market prices,
resulting in a final price aligned with your business strategy
(buying/selling, margins, operating costs).

Gold spread 24k (€/g)
Gold spread 22k (€/g)
Gold spread 20k (€/g)
Gold spread 18k (€/g)
Gold spread 14k (€/g)
Gold spread 9k (€/g)

✅ Ideal if you want to differentiate prices by karat and manage promotions
or different conditions between 18kt, 14kt, etc.

2) Silver spreads (€/g) by fineness

You can also configure a dedicated spread (€/g) for silver,
based on fineness, following the same principle:
pure value (from live prices) minus spread.

Silver spread 999 (€/g)
Silver spread 925 (€/g)
Silver spread 800 (€/g)

3) UI badge labels for Gold and Silver

You can customize the badge labels displayed in the calculator UI,
useful to highlight at a glance the main reference
(e.g. 24kt for gold, 999 for silver).

Gold badge label (e.g. “24Kt”)
Silver badge label (e.g. “999”)

✅ Perfect for matching the calculator to your brand style or communication
(e.g. “24K”, “24 kt”, “Au 999”).

4) Gold karat visibility (show / hide)

From the admin panel you can choose which gold karats are visible
in the calculator, so you only display what you actually trade in your store.

Show / Hide Gold 24k
Show / Hide Gold 22k
Show / Hide Gold 20k
Show / Hide Gold 18k
Show / Hide Gold 14k
Show / Hide Gold 9k

5) Silver fineness visibility (show / hide)

You can do the same for silver, selecting
which fineness levels are available to customers.

Show / Hide Silver 999
Show / Hide Silver 925
Show / Hide Silver 800

6) “Lock the Price” button (enable / disable)

You can choose whether to display the
“LOCK THE PRICE” CTA.
If disabled, the plugin works as a purely
informational calculator (no lead conversion).

Show “Lock the price” button (On / Off)

7) “Lock the Price” action mode

You can define what happens when users click “Lock the Price”,
based on your sales workflow and customer profile.

Disabled – completely disables the feature
WhatsApp – opens WhatsApp with a pre-filled message
Email – opens an on-site modal and sends a request via email (with server-side recalculation)
Print / Save as PDF – allows printing or saving a price summary

8) WhatsApp number (for quick requests)

If you use WhatsApp mode, you can set the phone number
that will receive customer messages.
The plugin uses this number to open the chat directly.

WhatsApp number (digits only, e.g. 3912345678)

9) Email recipient for price lock requests

If you choose Email mode, you can define the address
that will receive price lock requests.
Requests include metal type, karat/fineness, grams,
unit price, total price, and customer details.

Email recipient (lock requests) – recipient (default: WordPress admin email)

10) Security & reliability (anti-tampering logic)

In Email mode, prices are never trusted from the browser:
the plugin performs a full server-side recalculation
using live prices, purity coefficients, and configured spreads.
This guarantees full consistency between what users see
and what you receive.

Data validation (metal, karat/fineness, grams)
Server-side recalculation of unit price and total
AJAX nonce protection
Full input sanitization
