How to use the gold & silver value calculator

  1. Choose the metal and enter its weight in grams, troy ounces, kilograms or tola.
  2. Pick the purity: karat for gold jewelry (24K, 22K, 18K...) or fineness for bars and coins (.999, .925).
  3. The latest spot price per troy ounce loads automatically. Tap Refresh price for the newest quote.
  4. Optionally set a dealer premium to estimate what buying the same metal would cost.

How it's calculated

Everything is converted to troy ounces of pure metal first:

Pure troy oz = Weight in grams × Purity ÷ 31.1035

Metal value = Pure troy oz × Spot price

Purity is the karat ÷ 24 for gold (22K = 91.67%) or the fineness for bullion (.999 = 99.9%). The buying estimate adds the dealer premium: Value × (1 + premium).

Example

50 grams of 22K gold contains 1.474 troy ounces of pure gold. At an example spot price of $4,300 per troy ounce, that's worth about $6,337. A 1 kilogram bar of .999 silver holds 32.12 troy ounces, worth about $2,088 at $65 an ounce. The calculator above uses the live spot price instead.

Tips

  • Precious metals are priced per troy ounce (31.1 grams), which is heavier than a regular ounce (28.35 grams).
  • Jewelry usually sells for less than its metal value because buyers pay for the metal, not the design.
  • Compare the total price per ounce, including premium and shipping, across several dealers.
  • Be wary of sellers who pressure you, promise quick profits or discourage you from taking delivery.

Frequently asked questions

What is a troy ounce?
The standard unit for precious metals. One troy ounce equals 31.1035 grams, about 10% more than the everyday (avoirdupois) ounce of 28.35 grams.
What does karat mean?
Karat measures gold purity out of 24 parts. 24K is essentially pure gold, 22K is 22/24 or 91.67% gold, 18K is 75% and 14K is about 58.3%. The rest is other metals that add strength or color.
Why do dealers charge more than the spot price?
Spot is the price for large wholesale amounts. Coins and small bars carry a premium for minting, handling and the dealer's margin. Enter a premium to estimate your real cost.
Is the metal value what I'll get when I sell?
Usually not quite. Buyers typically pay somewhat below spot, especially for jewelry or scrap, so treat the metal value as the upper end of what you might receive.
Is the spot price live?
Yes. When you open the calculator it loads the latest spot price for the metal you choose and shows when it was last updated. Prices move throughout the day, so tap Refresh price to get the newest quote.
