Our Methodology

Last reviewed: 23 October 2026 · Prepared by: Wael Shaheen

This page explains how the gold and silver prices on GoldPricesGermany.com are obtained, calculated and updated, so you can judge how much weight to give them.

1. Where the prices come from

Spot prices for gold (XAU), silver (XAG) and currency pairs are provided by ForexInvestors.com, a real-time market data provider. The prices are delivered to this website in real time. The spot price is the international benchmark price for one troy ounce of the metal, quoted directly against the euro (XAU/EUR) and the US dollar (XAU/USD).

2. How we calculate per-gram and per-karat prices

Spot prices are quoted per troy ounce. We convert them with this formula:

price per gram = spot price per troy ounce ÷ 31.1035 × purity

One troy ounce is exactly 31.1035 grams. (This is different from the everyday ounce of 28.35 g.)
Purity is the fraction of pure gold in the alloy. 24K gold is shown as 99.9% (0.999), the typical purity of investment bars.
Larger units are multiples of the gram price: 10 g, 100 g and 1 kg.

Karat	Fineness	Purity used
24K	999	99.9%
23K	965	96.5%
22K	916	91.6%
21K	875	87.5%
18K	750	75.0%
14K	585	58.5%
12K	500	50.0%
10K	417	41.7%
9K	375	37.5%
8K	333	33.3%

3. Update frequency

Live spot prices are streamed in real time over WebSockets and update on the page instantly while the global market is open, with no need to refresh. The market status and countdown at the top of the page show whether the market is open or closed.
Local-market rates are updated a few times a day, based on the international price and exchange rates.
Charts and historical tables use daily data.

The "Last updated" time on each page shows when the displayed data was last refreshed. A short delay between the global market and this website is possible.

4. Spot price versus the price you pay

The prices shown are spot-based market prices. They do not include dealer premiums, minting costs, jewellery making charges or VAT. Retail prices at shops are normally higher than spot, and the buy-back price is normally lower. In Germany, investment gold (bars and coins that meet the legal purity requirements) is exempt from VAT, while jewellery and silver are subject to VAT. Always confirm the final price with your dealer.
