How much is your gold worth?Bookmark this page
The gold calculator is a generic gold melt value calculator which can be used to determine the value of gold metal inside an item with a known weight and gold purity. These items may include gold jewelry (such as, bangles, bracelets, chains, earrings, necklaces, pendants, and rings), gold bullion and gold coins.
The gold calculator is designed to calculate the gold metal value for one item at a time. If you would like to calculate the gold metal value for multiple items simultaneously consider using the scrap gold calculator for scrap gold, the gold bullion calculator for gold bullion bars and coins, and the gold coin calculator for gold coins.

This calculation determines the value of gold metal based on the weight, purity, and bid price for gold metal.
99.9% pure gold
|* Unit weight conversions|
|1 avoirdupois ounce (oz) = 28.349523125 g||1 baht = 15.244 g||1 carat (ct) = 0.2 g|
|1 grain = 0.06479891 g||1 kilogram (kg) = 1000 g||1 masha = 0.97 g|
|1 milligram (mg) = 0.001 g||1 pennyweight (dwt) = 1.55517384 g||1 pound (lb) = 453.59237 g|
|1 ratti = 0.1215 g||1 tael (China - Treasury standard) = 37.5 g||1 tael (Hong Kong) = 37.7993638 g|
|1 tola (India) = 11.6638038 g||1 tola (Pakistan) = 12.5 g||1 troy ounce (oz t) = 31.1034768 g|
This calculation determines a price relative to the value of gold metal from calculation 1.

The calculators on this page are for information purposes only.
We do not buy or sell precious metals.
Gold is often used inside alloys (mixture of metals).
The calculator on this page is only calculating the value of the gold metal component.
The calculators assume homogenous (uniform) composition.
Gold trades on international commodity markets.
This website uses the gold bid price which is different from the gold ask price and gold spot price:
Look under the gold price being used in the calculator to confirm when the price was last updated.
The live gold price is retrieved when the page first loads or when the currency is changed.
If you are on this webpage for some time then the price shown become less up-to-date, therefore we recommending refreshing the page every so often in this situation. The frequency you refresh is dependent on your tolerance for currency and price flucations and their effect on the calculator currency-denominated inputs and outputs.
Occasionally we are unable to connect to our live gold price feed.
If this occurs, the website will fall back to using the non-live gold price equivalent of the currency requested.
We aim to update the non-live gold price currencies once per hour.
Occasionally there will be a longer interval between updates.
All prices in this list should only be considered estimates due to small delays in data synchronization and the nature of price and currency fluctuations.
The gold metal value may only be one factor which influences the price.
Other factors may include, but not limited to:
The karat scale purity is rounded to 0.1%. For example, 8K is rounded to 33.3% (or 333 in fineness scale); rather than 33.33% recurring.
We are also using the rounded down fineness, as opposed to the rounded to nearest whole number fineness. See table below for the difference.
|Parts gold to alloy||
(Round to nearest whole number)
|24K||24 / 24||100||1000||1000|
|23K||23 / 24||95.83||958||958|
|22K||22 / 24||91.67||916||917|
|21.6K||21.6 / 24||90||900||900|
|21K||21 / 24||87.5||875||875|
|20K||20 / 24||83.33||833||833|
|19K||19 / 24||79.17||791||792|

For 24K gold, we offer 2 nines (990), 3 nines (999), 3 nines 5 (999.5), 3 nines 7 (999.7), 4 nines (999.9), 4 nines 5 (999.95), and 5 nines (999.99). See nine purity for more information.
Some manufacturers may stamp a particular karat but the fineness may vary slightly (for example, 14K gold which is 583 may be stamped 585).
We use a simple rounding algorithm in calculating currency-denominated values. This is due to accepting a large range of currencies and the need to present user-friendly numbers.
