Bullion Premium is a calculator and educational website designed to make the numbers behind precious-metal purchases easier to understand. It helps buyers separate a product’s metal value from the amount paid above or below that value.

The site was created and is maintained by Dmytro Svirepchuk. Dmytro also writes and reviews the guides published on Bullion Premium.

What Bullion Premium Helps You Calculate

The free Bullion Premium Calculator uses the values you enter to calculate:

• fine metal weight;
• melt value;
• premium amount;
• premium as a percentage of melt value.

The same calculation framework can be used for gold, silver, platinum, and palladium. The calculator is intended for comparing products on a consistent mathematical basis. It does not determine whether a product is authentic, fairly graded, collectible, liquid, or suitable for a particular buyer.

For a detailed explanation of every input, formula, rounding rule, and limitation, see How Bullion Premium Calculations Work.

Why the Site Exists

Bullion listings often combine several different numbers: total product weight, precious-metal content, purity, spot price, dealer price, and premium. Two products can have similar prices but contain different amounts of fine metal. A lower product price can also hide a higher premium when weight or purity differs.

Bullion Premium was built to make those comparisons explicit. The calculator performs the arithmetic, while the bullion guides explain the concepts needed to interpret the result.

Useful starting points include:

• What Is Premium Over Spot?
• How to Calculate Bullion Premium Over Spot
• Spot Price vs. Melt Value: What’s the Difference?
• Troy Ounce vs. Ounce: What’s the Difference?
• Gold Purity Explained: Karats, Fineness, and Fine Gold Weight
• Silver Purity Explained: .999, .925, and Other Standards

Editorial Approach

Bullion Premium aims to publish practical explanations that a reader can verify and use. Articles are written around a specific question rather than a target word count.

When preparing or reviewing content, the site follows these principles:

1. Show the calculation. Important numerical claims should be supported by a formula, a worked example, or both.
2. Separate defined values from assumptions. Product weight and purity may come from official specifications, while prices used in examples are identified as hypothetical.
3. Prefer primary sources. Unit conversions, product specifications, hallmarking rules, and benchmark information are checked against sources such as NIST, official mints, government guidance, and recognized precious-metals institutions.
4. Link to the source. When an external fact is material to the explanation, the relevant guide should provide a direct link to the source where practical.
5. Avoid personalized recommendations. Guides explain calculations and terminology; they do not tell an individual what to buy or predict future metal prices.
6. Review related pages together. When a formula, definition, or calculator behavior changes, the corresponding methodology and educational content should be checked for consistency.

Authorship and Review Dates

Each guide identifies its author and publication or review date. An Updated or Last reviewed date should change only after a meaningful review of the page. Cosmetic edits alone are not a reason to present content as newly reviewed.

Some market practices, product specifications, regulations, and external resources can change. A review date shows when the published explanation was last checked; it is not a guarantee that every external source will remain unchanged afterward.

Sources

The type of source depends on the claim being checked. Examples include:

• NIST for unit definitions and troy-weight conversions;
• official mint pages for bullion coin specifications;
• government hallmarking guidance for legally defined fineness marks;
• LBMA pages for information about precious-metal benchmark prices and market standards;
• consumer-protection agencies for general guidance about precious-metal labeling and jewelry claims.

Dealer listings may be used to illustrate how a product is offered, but a dealer’s marketing page should not replace an authoritative source for a unit definition, legal standard, or official coin specification.

The calculator does not automatically certify the accuracy of any value entered by a user. The calculation methodology explains how inputs are interpreted.

Corrections

Accuracy matters, especially when a small difference in weight, purity, or units can materially change a result. If you find a possible factual, mathematical, source, or accessibility issue, use the email support link.

When reporting a problem, please include:

• the URL of the page;
• the text or result that may be incorrect;
• the calculator inputs, if the issue involves a calculation;
• a supporting source, if available.

Corrections are reviewed against the calculator logic and the most relevant available sources. If a published page is materially changed, its review date should be updated as part of that review.

Important Limitations

Bullion Premium provides calculation tools and general educational information. It does not authenticate products, provide appraisals, quote an executable dealer price, estimate taxes, or guarantee a resale value.

All examples are hypothetical unless clearly identified otherwise. Nothing on this site is financial, investment, tax, or legal advice. Verify product specifications and current prices independently before making a transaction.
