Platinum calculator

How much is your platinum worth?

Bookmark this page

The platinum calculator is a generic platinum melt value calculator which can be used to determine the value of platinum metal inside an item with a known weight and platinum purity. These items may include platinum jewelry (such as, bangles, bracelets, chains, earrings, necklaces, pendants, and rings), platinum bullion and platinum coins.

The platinum calculator is designed to calculate the platinum metal value for one item at a time. If you would like to calculate the platinum metal value for multiple items simultaneously consider using the scrap platinum calculator for scrap platinum, the platinum bullion calculator for platinum bullion bars and coins, and the platinum coin calculator for platinum coins.

Additional information

  • Hallmarks - "PT", "PLAT" or even "PLATINUM" next to a number in millesimal fineness scale.
  • Troy weight - preferred unit of mass for precious metals.
  • Millesimal fineness scale - purity expressed as a proportion of 1000.



The calculators on this page are for information purposes only.

We do not buy or sell precious metals.

Platinum melt value only

Platinum is often used inside alloys (mixture of metals).

The calculator on this page is only calculating the value of the platinum metal component.

Solid platinum jewelry

The calculators assume homogenous (uniform) composition.

Platinum price

Platinum trades on international commodity markets.

This website uses the platinum bid price which is different from the platinum ask price and platinum spot price:

  • Bid price: The price for immediate purchase.
  • Ask price: The price for immediate sale.
  • Spot price: The price trading (buying and selling) is occurring for immediate delivery.
  • Bid-ask spread: The difference between the bid price and the ask price.

Look under the platinum price being used in the calculator to confirm when the price was last updated.

Live platinum price

The live platinum price is retrieved when the page first loads or when the currency is changed.

If you are on this webpage for some time then the price shown become less up-to-date, therefore we recommending refreshing the page every so often in this situation. The frequency you refresh is dependent on your tolerance for currency and price flucations and their effect on the calculator currency-denominated inputs and outputs.

Occasionally we are unable to connect to our live platinum price feed.

If this occurs, the website will fall back to using the non-live platinum price equivalent of the currency requested.

Non-live platinum price

We aim to update the non-live platinum price currencies once per hour.

Occasionally there will be a longer interval between updates.

All prices in this list should only be considered estimates due to small delays in data synchronization and the nature of price and currency fluctuations.

Other price influences

The platinum metal value may only be one factor which influences the price.

Other factors may include, but not limited to:


We use a simple rounding algorithm in calculating currency-denominated values. This is due to accepting a large range of currencies and the need to present user-friendly numbers.
