How we calculate your price
Your price is weight × fineness × spot price, minus a fixed margin per type. Every step is below, with a worked example you can repeat yourself.
The formula
Every buying price on this site comes from the same sum:
buying price = weight (grams) × fineness ÷ 1000 × spot price per gram × (1 − margin)
Fineness is in thousandths: 585 means 585 parts pure gold per 1000, so 58.5%. The margin depends on what you sell and is listed per type below.
Where the spot price comes from
- The spot price is the world market price of the pure metal, right now.
- XGOUD fetches it from Swissquote every minute, as the mid-price between bid and ask.
- Precious metals are quoted in dollars per troy ounce. XGOUD converts to euros per gram using the current EUR/USD rate and 31.1034768 grams per troy ounce.
- At the table, the price of that moment applies.
Weight and fineness
- XGOUD weighs on a calibrated scale, while you watch.
- XGOUD measures fineness with an X-ray device (XRF), which does not affect metal or stone, and calculates with the measured fineness.
- Weight, fineness, price and amount are then shown on your purchase receipt.
The margin per type
This share of the spot price is what XGOUD pays, on the pure metal in your item. The percentages come from the same setting used to calculate every price on the site.
| What you sell | Of the spot price | For a larger lot |
|---|---|---|
| Gold bars | 98% | – |
| Gold bullion coins (Krugerrand, Maple Leaf) | 100% | – |
| Dutch gold ten-guilder coins and ducats | 100% | – |
| Fine gold, 24 carat (999) | 91% | – |
| 22-carat gold (916) | 91% | 91.3% from 501 grams |
| 18-carat jewellery (750) | 91% | 91.3% from 501 grams |
| 14-carat jewellery (585) | 91% | 91.3% from 501 grams |
| Silver bars | 98% | – |
| Silver bullion coins | 98% | – |
| Dutch and Belgian silver coins | 98% | – |
| Historic silver coins | 96% | – |
| Fine silver (999) | 98% | – |
| Sterling silver (925) | 72% | – |
| Platinum bars | 94% | – |
| Platinum coins | 98% | – |
| Platinum 950 | 91% | – |
| Palladium bars | 94% | – |
| Palladium coins | 98% | – |
| Palladium 950 | 91% | – |
Larger lots get a slightly lower margin; the right-hand column shows from which weight.
Worked example
With a round spot price of € 100 per gram – so not today’s price – 10 grams of 14-carat gold (585) works out like this:
- Pure gold: 10 × 585 ÷ 1000 = 5.85 grams
- Material value: 5.85 × € 100 = € 585.00
- Margin (9%): − € 52.65
- You receive: € 532.35, which is 91% of the material value
Today’s amounts are on the price pages and in the calculator.
Coins, settings and collector’s value
- XGOUD buys gold coins at 100% of the spot price, on the gold they contain.
- If a coin sits in a setting or pendant of 585 or higher, XGOUD buys the setting as scrap gold (91% of the spot price); the coin follows its own percentage.
- XGOUD assesses the collector’s value of a coin separately and tells you at the table.
Diamonds, gemstones and watches
- There is no market price for diamonds and gemstones. The value depends on the stone itself – weight, colour, clarity and cut – and is set at the table.
- The watchmaker assesses a brand watch on brand, model and condition; that price does not follow from the metal price alone.

In four steps
Weigh
On a calibrated scale, while you watch.
Measure fineness
With X-ray fluorescence (XRF), without damaging the item.
Apply the spot price
Weight × fineness × the spot price of that moment gives the material value.
Deduct the margin
The fixed margin for that type comes off: that is your amount, on the purchase receipt.
Frequently asked questions
What is the difference between the spot price and the buying price?
The spot price is the world market price of the pure metal. The buying price is what XGOUD pays you: weight × fineness × spot price, minus the margin for that type – 98% of the spot price for gold bars, 91% for gold jewellery.
Why do I get less for jewellery than for a bar?
Jewellery has to be melted and refined before it becomes pure gold again; a bar is already pure. That is why the margin on jewellery and scrap gold is higher than on bars and coins.
How often does the price change?
XGOUD fetches the spot price every minute. At the table the price of that moment applies; with the price guarantee you fix a calculated price for 48 hours, up to € 2,500.
Does a coin’s collector’s value count?
XGOUD assesses the collector’s value separately and tells you at the table. The gold in the coin always counts, at 100% of the spot price.
