The platinum calculator is a 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.

Calculation 1: Value of platinum metal

This calculation determines the value of platinum metal based on the weight, purity, and bid price for platinum metal.

Step 1: Convert the weight of the platinum alloy into troy ounces
Weight of platinum alloy
= Weight of platinum alloy × Conversion factor
= 0 × 31.1034768
= 0 oz t
Step 2: Convert the weight of the platinum alloy into the weight of platinum metal
Weight of platinum metal
= Weight of platinum alloy × Platinum purity (%) ÷ 100
= 0 × 99.9 ÷ 100
= 0 oz t
Step 3: Calculate the value of platinum metal
Value of platinum metal
= Weight of platinum metal × Price of platinum metal
= 0 × 0
= 0

* Unit weight conversions
1 avoirdupois ounce (oz) = 28.349523125 g 1 baht = 15.244 g 1 carat (ct) = 0.2 g
1 grain = 0.06479891 g 1 kilogram (kg) = 1000 g 1 masha = 0.97 g
1 milligram (mg) = 0.001 g 1 pennyweight (dwt) = 1.55517384 g 1 pound (lb) = 453.59237 g
1 ratti = 0.1215 g 1 tael (China - Treasury standard) = 37.5 g 1 tael (Hong Kong) = 37.7993638 g
1 tola (India) = 11.6638038 g 1 tola (Pakistan) = 12.5 g 1 tonne (t) = 1000 kg
1 ton (short) = 907.18474 kg 1 ton (long) = 1016.047 kg 1 troy ounce (oz t) = 31.1034768 g


Calculation 2: Platinum sellers - what price should I sell for?

This calculation determines a price relative to the value of platinum metal from calculation 1.

This calculation is useful for people selling platinum. For people selling to a platinum buyer for cash it helps you negotiate a fair price. For people onselling platinum it helps determine listing prices.

In addition, this calculation can also be used by platinum buyers to come up with offer prices.


Step 1: Calculate price relative to the value of platinum metal
= Value of platinum metal × Platinum metal value (%) ÷ 100
= 0 × 0 ÷ 100
= 0

Calculation 3: Platinum buyers - is it cheap or expensive?

This calculation determines how the price compares relative to the value of platinum metal from calculation 1.

This calculation is useful for people buying platinum. In general, how far the price deviates from the platinum metal value determines if it is cheap or expensive.


Step 1: Calculate platinum metal value (%)
Platinum metal value (%)
= Price ÷ Value of platinum metal × 100
= 0 ÷ 0 × 100
= 0 %

Potential use cases

  • General public: Make informed decisions when buying or selling platinum.
  • Cash for platinum: Platinum buyers can quickly calculate offers to sellers of platinum.
  • Platinum cost calculator: Jewelers can calculate the cost of platinum for jewelry they are making.
  • Platinum recyclers: Refiners can calculate the value of platinum to be melted down.
  • Businesses selling used platinum jewelry: Pawnbrokers, antique stores, and secondhand jewelry stores can quickly calculate listing prices based on a price relative to the platinum metal value inside the used platinum jewelry.



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.
