Free Bullion Premium Calculator
Calculate a gold, silver, platinum or palladium product's premium over spot. Add quantity, fine-metal content, tax and fixed order costs to estimate the effective all-in premium, buyback gap and break-even spot price.
Bullion Price Over Spot Calculator
Compare a bullion product's dealer price with the spot value of its fine-metal content. Enter one currency and a spot price from the same valuation time as the dealer quote.
The estimate compares entered acquisition costs with fine-metal spot value.
No live spot price, exchange rate, tax rule or guaranteed buyback is supplied. Numismatic or collectible value is outside this calculator.

A bullion premium is the amount a buyer pays above the spot or reference value of the product's fine precious-metal content. This calculator separates the product-level premium from taxes and order costs so that a low advertised premium is not confused with the total acquisition cost.
Bullion Premium Formulas
Total acquisition cost in this tool equals the dealer product subtotal plus the entered tax and fixed order costs. A negative result is displayed as a discount to the entered spot value.
How to Use the Calculator
- Select the metal and one currency code.
- Enter a same-time spot or reference price with its exact unit.
- Choose whether the weight is stated fine-metal content or gross product weight.
- If using gross weight, enter the verified metal purity.
- Enter quantity and the dealer price per item before tax and order fees.
- Add any applicable tax rate and fixed order costs.
- Optionally enter a same-time dealer buyback price to estimate the immediate spread.
Fine Content Versus Gross Product Weight
| Product statement | Calculator basis | Reason |
|---|---|---|
| Contains 1 troy ounce fine gold | Fine-metal content stated directly | Use 1 oz t even if the alloyed coin's gross weight is higher. |
| 31.103 g bar, 99.99% gold | Gross weight plus purity | Fine content equals gross weight × 99.99%. |
| 1 troy ounce .999 silver | Either, if entered consistently | Fine content is 0.999 oz t when 1 oz t is gross weight. |
| Collectible or numismatic coin | Metal value only | Rarity, grade, provenance and collector demand are outside the formula. |
Product Premium Versus Effective All-In Premium
The Royal Mint explains that bullion premiums may be percentage-based or fixed monetary amounts and that there is no single industry-standard premium. Manufacturing, distribution, design and dealer costs can contribute to the premium.
Worked Bullion Premium Example
Assume a hypothetical one-ounce fine-gold product with a spot price of USD 2,400 per troy ounce:
- Dealer price: USD 2,520 per item, a USD 120 or 5% product premium.
- Quantity: 2 items, so the product subtotal is USD 5,040.
- Entered tax: 2%, adding USD 100.80.
- Fixed order costs: USD 40.
- All-in acquisition cost: USD 5,180.80.
- Total spot value: USD 4,800.
- Effective all-in premium: USD 380.80 or approximately 7.93%.
- Metal-value break-even spot: USD 2,590.40 per fine troy ounce.
If a current dealer buyback is USD 2,352 per item, it is 2% below the entered spot value. The immediate resale total would be USD 4,704, leaving a USD 476.80 shortfall before any extra selling costs.
How the Break-Even Prices Work
The metal-value break-even spot assumes the fine metal alone must equal all acquisition costs. It does not assume that a future buyer will pay a product premium. The optional buyback-model break-even keeps the entered buyback premium or discount percentage constant as spot changes. Dealer spreads and premiums can change, so this is a scenario rather than a forecast.
What Can Create a Bullion Premium?
- Minting, refining, fabrication and quality-control costs.
- Product size, with smaller fractional items often carrying higher percentage costs.
- Wholesale and dealer distribution margins.
- Demand, inventory availability and delivery location.
- Packaging, assay cards, security features and brand recognition.
- Payment method, shipping, insurance, storage and handling.
- Taxes or duties under the buyer's applicable rules.
Spot Price, Melt Value and Dealer Price
Spot or benchmark prices generally describe wholesale or unallocated market references, not the final delivered retail price of a specific bar or coin. Melt value is the spot-based value of contained fine metal. Dealer ask is the purchase price offered to a customer, while dealer bid or buyback is what the dealer offers to pay. Comparing an ask with spot measures acquisition premium; comparing ask with buyback measures a round-trip spread.
Troy-Ounce and Purity Checks
A troy ounce equals 31.1034768 grams. It is not the 28.349523125-gram regular ounce. Select the actual unit printed in the quote or specification. When a product states guaranteed fine-metal content, use that contained amount; do not multiply it by purity a second time.
Comparing Bullion Dealer Quotes
- Record spot price, dealer quote and buyback quote at the same time.
- Compare identical metal, weight, purity, mint, product and quantity tiers.
- Ask whether prices change with payment method or order size.
- Include tax, shipping, insurance, storage and future selling costs.
- Verify delivery, cancellation, return and buyback terms in writing.
- Do not assume a collectible premium will be recovered at resale.
Risk and Consumer Protection
Precious-metal prices can be volatile, and premiums can increase or disappear independently of spot. The CFTC warns that premiums, fees and commissions can drain returns and that precious metals are not risk-free. Avoid guaranteed-profit claims, high-pressure sales and unexplained markups.
