About the Silver Price Calculator
The Silver Price Calculator works out the melt value of silver from its weight, its fineness and a spot price you type. It opens with Silver selected and the fineness set to 925, the mark for sterling silver. Presets cover the common hallmarks: 999 fine silver, 958 Britannia silver, 925 sterling, 900 coin silver and 800. Weights can be grams, troy ounces or pennyweights, and the spot price can be per gram or per troy ounce, the unit most quotes use.
Silver is never measured in karats, so only fineness is offered: the parts of pure silver in every thousand. The page fetches no prices; you type a current spot price from a quote you trust. The troy ounce is converted with its exact definition, 31.1034768 grams, and the value is worked out as one exact fraction and rounded once to the cent.

Frequently asked questions
How do I calculate the value of sterling silver?
Multiply the weight by 0.925, the purity of sterling silver, and by the spot price for the same unit. 100 g is 3.2150747 troy ounces, so at 30.00 an ounce it is worth 3.2150747 × 0.925 × 30 = 89.22.
What does 925 mean on silver?
It is the fineness, the parts of pure silver per thousand. Sterling silver is 925, or 92.5 percent silver. Other common marks are 999 for fine silver, 958 for Britannia silver, 900 for coin silver and 800.
Is silver priced per gram or per ounce?
Spot prices are usually quoted per troy ounce, which is exactly 31.1034768 grams. Pick Per troy ounce or Per gram to match your quote; the calculator converts with the exact factor and also shows the price per gram.
Why is there no karat option for silver?
Karats are only used for gold. Silver and platinum purity is always given as fineness in parts per thousand, so 925 silver is 92.5 percent pure.
Is this what a buyer will pay for my silver?
No. The result is melt value at the spot price you typed. Buyers usually pay less, and silverware or jewellery may be worth more for its design. Check a current quote; the result is an estimate.
