How the silver price calculator works
The calculator uses the live fine silver (999) spot price per gram as its base. Your entered weight is first converted to grams (1 troy ounce = 31.1034768 grams, 1 tola = 11.6638038 grams). The value is then adjusted for purity using the standard you select: the purity multiplier is the fineness divided by 1000, so sterling silver uses a multiplier of 925 รท 1000 = 0.925.
The full formula is: value = grams ร price per gram ร (fineness รท 1000). Optional premium and discount percentages are applied on top of this spot value to model making charges or buyback spreads.
