Formula
Value = fine troy ounces × your spot price.
Fine troy ounces = weight in troy ounces × (karat ÷ 24). Grams divide by 31.1034768. Pennyweights divide by 20. The scrap gold calculator does not fetch a market feed.

Scrap gold calculator for karat, weight, and spot price
This scrap gold calculator is for a jeweler or a refiner checking a lot before it goes to assay. It converts grams, pennyweights, or troy ounces to fine troy ounces at the karat you choose, then multiplies by the spot price you type. The price is an input, not today's fix and not a buyer’s check.

How it works
Fine gold is weight times karat over 24.
A troy ounce is 31.1034768 grams, and a pennyweight is one twentieth of a troy ounce. Purity is the karat divided by 24, so 14 karat is 14/24. Ten grams of 14 karat gold is about 0.3215 troy ounces and about 0.1875 fine troy ounces. At a $2,000 spot price the gross value is about $375.09. Those fields are already filled in. A refiner’s discount, an assay fee, and stones left in the mounting are not deducted. Plated pieces are not the karat stamped on a different item. Copper and other metals sold by the pound belong on the scrap metal calculator.

Example
10 grams of 14 karat gold at a $2,000 spot price.
Fine content is about 0.1875 troy ounces. Gross value is about $375.09. Replace $2,000 with the spot price you are using for the lot. It is an example input, not a published fix.

Tips
Gross value is not a settlement.
Weigh on a scale you trust and keep stones out of the gold weight. A bar and a mixed jeweler’s lot do not share a refining fee. Type the price you were quoted, or the price you want to test, and label the result as gross.

Equipment
Testing and refining equipment is the purchase.
An XRF gun, a furnace, or a rolling mill is equipment. Dengaro arranges equipment financing for that shop. The gold value is not sent as a loan amount.
Important questions
Know what to expect.
Is the spot price today’s gold price?+
No. The field starts at 2,000 so the example is round. Type the price per troy ounce you want to test. This scrap gold calculator does not download a quote.
What purity is 10 karat, 18 karat, and 24 karat?+
Divide the karat by 24. 10 karat is 41.67 percent, 18 karat is 75 percent, and 24 karat is 100 percent. The selector does that division.
Does the result deduct a refining fee?+
No. The headline is gross metal value from the weight, the karat, and the price you entered. Any fee a refiner takes off is outside this arithmetic.
Where do I price copper or steel?+
On the scrap metal calculator, in pounds times your price per pound. This page stays on karat gold.
