Gold Price Calculator

The calculator works in two directions. On the left, enter the amount of gold you have and choose its unit. The calculator multiplies the amount by the current live spot price and displays the U.S. dollar value.

On the right, enter a dollar amount. The calculator divides by the current spot price to show how much gold that amount would buy, expressed in troy ounces, grams, and kilos.

The calculator uses the live spot price of gold from COMEX gold futures (GC=F). The price updates each minute the market is open.

How do I calculate the value of my gold?

Enter the amount of gold you have and select the unit (troy ounces, grams, or kilos). The calculator multiplies your amount by the current live spot price to show the value in U.S. dollars.

What price does this calculator use?

The calculator uses the live spot price of gold from COMEX gold futures (GC=F), the largest gold futures market in the world. The price updates each minute the market is open.

How do you convert between troy ounces, grams, and kilos?

One troy ounce equals 31.1035 grams, and one kilogram equals 32.1507 troy ounces. To convert a per-ounce price to per-gram, divide by 31.1035. To convert to per-kilo, multiply by 32.1507.

Does this include the dealer premium?

No. The calculator shows the spot price value of the metal itself. Dealers charge a premium above spot when selling physical bullion, and pay a discount below spot when buying. Typical premiums range from one to five percent for large bars and ten to twenty percent for small coins.
