How to Use
This Platinum Calculator

Enter the weight of your platinum item and select its purity grade.
The calculator uses today's live platinum spot price to give you an instant melt value estimate.

01

Weigh Your Platinum

Use a digital jewelry scale accurate to 0.01 grams. Platinum is dense, so even a small ring carries real value — weigh each piece on its own. If you don't have a scale, many jewelers and coin shops will weigh items for free.

02

Identify the Purity

Look for a hallmark stamp. Common marks: PLAT, PT, or 950 for platinum 950, PT900 or 900 for older pieces, and 999 or 9995 for bullion. In the US, a piece marked simply "Platinum" or "Plat" is at least 95% pure. If there's no mark, a jeweler can test the metal.

03

Understand the Result

Melt value is the raw metal content at today's spot price — your baseline floor. Actual resale value can be much higher depending on the maker, era, setting, and any gemstones.

Units Supported

Grams (g), troy ounces (ozt), pennyweights (dwt), and avoirdupois ounces (oz). One troy ounce = 31.1035 grams. One pennyweight = 1.55517 grams.
