The **Gold Calculator** calculates the current bullion value for pure gold (SPOT), scrap gold and commonly traded coins such as the U.S. British SovereignGold Eagle, South African Krugerrand, Canadian Maple Leaf, and the British Sovereign.

**Gold Value:**This computes the value of gold based on the weight, karat purity, a refiner's fee and a fee to the retailer (jeweler).**Alloy Value:**This computes the value of platinum, palladium, silver or gold based on the weight, percent purity, a refiner's fee and a fee to the retailer (jeweler).**Gold SPOT:**This is the value of a gram, penny weight or troy ounce of gold bullion (.9999) in U.S. dollars or other currencies.**Density of Gold:**This is the mean density of gold bullion (.9999).**Gold Eagle:**This computes the value of U.S. Gold Eagle coins based on their size, the number of coins, SPOT and any numismatic adders.**Krugerrand:**This computes the value of South African Krugerrand coins based on their size, the number of coins, SPOT and any numismatic adders.**British Sovereigns:**This computes the value of British Sovereign coins based on the number of coins, SPOT and any numismatic adders.**Maple Leaf:**This computes the value of Canadian Maple Leaf coins based on their size, the number of coins, SPOT and any numismatic adders.

The Gold Calculator has equations providing the current value of gold, gold scrap and gold coin inclusive of the current bullion price for of a few well known gold coins. It also provides the current Spot price for selected precious metals. It uses the characteristics of well known coins such as the Krugerrand, Gold Eagle and Maple Leaf to determine the bullion value based on the current precious metals market price. The equations also allow for a numismatic value to be added to the equation. Currently, all the values are returned in U.S. dollars. Canadian

Maple Leaf

The **Gold Value** equation computes the refined gold value based on the following factors:

- weight
- purity (karat)
- refinement cost (%)
- profit (%). The profit is the jeweler's expected profit that is included in the buy price or value of the gold you will receive.

The **Alloy Value** equation is similar to the Gold Value equation except it allows you to choose gold and other metals (platinum, palladium and silver) and it take the purity as a percentage. For example, Sterling Silver is 92.5% pure and fine silver is 99.9% pure.KrugerrandU.S. Gold Eagle

This calculator currently has equations for the Krugerrand, Gold Eagle, Maple Leaf, and British Sovereign. Each equation uses the current spot price, the coin's weight and the percent of precious metal (karat) to formulate the bullion value for the number of coins. The equations also provide for a unit numismatic value that can be added per coin.

The Gold Spot equations show the current market price for the specific precious metal.

Coins that are minted with precious metals fluctuate in value based on the bullion content of the coin. Different coins have different weights and different percentages of precious metals. This calculator uses the publish weight and purity of the coins with the current spot price of the precious metal to provide an useful estimate of the current market value of the bullion in the coins. The equations also provide an input for the numismatic value of coins that is added to the bullion value.
