What is a Platinum Scrap Calculator?
A platinum scrap calculator is a specialized tool designed to estimate the intrinsic melt value of items containing platinum. This value is based on the item’s weight, its purity (the percentage of pure platinum in the alloy), and the current market price of platinum. It’s used by jewelers, investors, and individuals to determine the base value of scrap jewelry, coins, or industrial platinum before any additional costs like refining or fees are considered. Our precious metal refining process ensures you get the best value.
Platinum Scrap Calculator Formula and Explanation
The calculation for determining the value of your scrap platinum is straightforward. It involves converting all units to a standard, calculating the pure metal content, and then multiplying by the market price.
The core formula is:
Estimated Value = (Total Weight × Purity Percentage) × Price Per Unit of Weight
To ensure accuracy, all units must be consistent. Since platinum is traded internationally in Troy Ounces, our calculator converts all weights to Troy Ounces before the final calculation.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total Weight | The gross weight of the platinum item. | Grams, Pennyweight, Troy Ounces | 0.1 – 5,000 |
| Purity Percentage | The amount of pure platinum in the item, expressed as a decimal. | Decimal (e.g., 0.950) | 0.850 – 0.999 |
| Market Price | The spot price of pure platinum. | Currency per Troy Ounce | $800 – $1,500+ |
Practical Examples
Example 1: A 950 Platinum Ring
Let’s say you have a platinum ring stamped “PT950”.
- Inputs:
- Weight: 12.5 grams
- Purity: 950 Platinum (95%)
- Market Price: $950 per Troy Ounce
- Calculation:
- Convert weight to Troy Ounces: 12.5 g / 31.1035 g/oz t ≈ 0.4019 oz t
- Calculate pure platinum weight: 0.4019 oz t × 0.95 = 0.3818 oz t
- Result: 0.3818 oz t × $950/oz t ≈ $362.71
This is the estimated intrinsic value of the platinum in the ring. For more details on purity, see our karat purity guide (note: applies to gold, but the concept is similar).
Example 2: An old 900 Platinum Piece
Suppose you find an older piece of platinum jewelry marked “900 PLAT”.
- Inputs:
- Weight: 3.5 pennyweight (dwt)
- Purity: 900 Platinum (90%)
- Market Price: $950 per Troy Ounce
- Calculation:
- Convert weight to Troy Ounces: 3.5 dwt / 20 dwt/oz t = 0.175 oz t
- Calculate pure platinum weight: 0.175 oz t × 0.90 = 0.1575 oz t
- Result: 0.1575 oz t × $950/oz t ≈ $149.63

How to Use This Platinum Scrap Calculator
- Enter Platinum Weight: Weigh your item on a precise scale and enter the number in the “Platinum Weight” field.
- Select Weight Unit: Choose the unit your scale uses (Grams, Troy Ounces, or Pennyweight) from the dropdown menu.
- Select Purity: Look for a hallmark on your item (e.g., PT950, 900PLAT, 850). Select the corresponding purity from the list. If you’re unsure, 950 is the most common for modern jewelry.
- Enter Market Price: Look up the current spot price of platinum (usually quoted per troy ounce) and enter it. A default value is provided as a starting point.
- Interpret Results: The calculator will instantly display the “Estimated Platinum Value,” which is the primary result. You can also review intermediate values like the pure platinum weight and total weight in troy ounces.
Key Factors That Affect Platinum Scrap Value
- Purity (Fineness): This is the most critical factor. An item that is 95% platinum (950) is inherently more valuable than one that is 85% platinum (850), even at the same weight.
- Total Weight: The heavier the item, the more platinum it contains, and the higher its value. A precise digital scale is essential for an accurate estimation.
- Current Market Price: The value of platinum fluctuates daily based on global supply and demand. The price you get today could be different from yesterday or tomorrow. Check the current platinum price regularly.
- Unit Conversions: Inconsistencies in units (e.g., weighing in grams but using a price per ounce without conversion) are a common source of error. Precious metals use Troy Ounces (31.1035g), not standard Avoirdupois ounces (28.35g).
- Refining and Assaying Fees: A buyer will deduct costs for melting, assaying (testing for exact purity), and processing the scrap. Our calculator provides the gross value, not the final payout.
- Attached Gemstones or Other Metals: Any non-platinum materials must be removed or their weight subtracted from the total weight to get an accurate scrap value.
Frequently Asked Questions (FAQ)
- What do the numbers like 950, 900, and 850 mean on platinum?
- These numbers represent the platinum’s purity in parts per thousand. For example, “950” means the item is 950 parts pure platinum out of 1000, or 95% pure. The remaining 5% is typically other metals like iridium, ruthenium, or cobalt.
- Is this platinum scrap calculator 100% accurate?
- This calculator provides a highly accurate estimate of the *intrinsic melt value* based on your inputs. However, the final price a dealer offers may be lower due to refining fees, assay costs, and their own profit margin.
- Why is the price quoted per Troy Ounce?
- The Troy Ounce is the standard international unit of measurement for precious metals trading. One Troy Ounce is approximately 31.1035 grams, slightly heavier than a standard ounce.
- What if my item has no purity stamp or hallmark?
- If there is no hallmark, the item may be a different metal (like white gold or steel) or its purity is unknown. The only way to be certain is to have it professionally tested by a jeweler or a precious metals dealer.
- Does this calculator work for industrial platinum scrap?
- Yes. If you know the weight and purity of industrial platinum, such as from catalytic converters or laboratory equipment, you can use this calculator to find its melt value. However, extracting and refining industrial platinum can be more complex.
- Will I get the price shown by the calculator from a buyer?
- No, you will typically receive a percentage of the calculated value. Buyers have overhead and processing costs. Expect offers to be anywhere from 70% to 95% of the spot value, depending on the buyer and the quantity of scrap.
- How do I convert grams to pennyweight (dwt)?
- There are 1.555 grams in one pennyweight. To convert grams to dwt, divide the gram weight by 1.555. There are 20 pennyweights in one troy ounce.
- Should I remove gemstones before weighing?
- Yes, absolutely. Gemstones do not contribute to the platinum’s value and their weight will inflate the estimate. For the most accurate result, weigh only the metal.
