Bullion Break-Even Calculator
Calculate the future spot-price reference at which modeled bullion sale proceeds would recover entered purchase, acquisition, holding and selling costs under a declared dealer buy-back discount.
Enter the bullion position and round-trip assumptions
Use fine troy ounces and total costs for the full position. The buy-back discount models an entered percentage below a future spot reference; it is neither retrieved nor verified.

How bullion break-even spot is calculated
Modeled buy-back rate = 1 − entered discount %
Break-even spot = (outlay before sale + selling costs) ÷ (fine troy ounces × buy-back rate)
Net proceeds = fine ounces × break-even spot × buy-back rate − selling costs
Physical-bullion break-even is a round-trip cost problem. Purchase price, separate acquisition costs and cumulative holding costs form the amount to recover before sale. Selling costs are added to the numerator because gross sale value must also cover them.
Dealers commonly sell above spot and buy below spot, but the spread varies by product, quantity, dealer and market conditions. This model expresses the sale side as an entered discount below a hypothetical future spot reference. A 3% discount means modeled gross dealer payment is 97% of that future fine-metal value.
The equation divides all amounts to recover by fine troy ounces and the modeled buy-back rate. An optional current reference only shows the arithmetic change between that input and break-even. It adds no probability, timing or price-path information and must not be presented as expected appreciation.
Build a complete bullion break-even scenario
Separate sunk purchase costs from future sale assumptions, then review the result as a sensitivity threshold rather than a price target.
- Enter total fine troy ounces, not only product count or gross package weight.
- Include the full product price and add acquisition costs only when they are not already included.
- Accumulate entered storage, insurance or other holding costs over the chosen scenario horizon.
- Enter selling costs separately from the dealer discount so both assumptions remain inspectable.
- Use a buy-back discount supported by a current product-specific quote or policy; the calculator supplies no default evidence.
- Test more than one cost and discount scenario because dealer terms, market liquidity and product condition can change.
Worked example from the audited fixture
How to interpret the result
USD 2,847.94 per ounce is the exact reference that balances the fixture equation. It does not say that gold will reach that price, when it might happen, or that a dealer will buy the items at 97% of spot. Replace every cost and sale assumption with product-specific evidence.
Melt value, premium and break-even answer different questions
These calculators share one deterministic bullion-cost engine, but their denominators and decisions are different. Melt value starts from gross weight and fineness. Premium starts from known fine ounces and compares acquisition price with entered metal value. Break-even carries fine ounces and every entered round-trip cost into a future spot-reference equation.
| Bullion tool | Question answered | Required evidence | Primary output | Does not answer |
|---|---|---|---|---|
| Melt Value | What is the entered fine-metal reference? | Gross weight, unit, fineness, spot input | Entered metal-content value | Dealer cash bid or appraisal |
| Premium | How far is this acquisition price above or below metal value? | Fine ounces, spot input, product price and costs | Quoted and all-in premium | Whether the offer is fair |
| Break-Even | What future spot reference balances entered round-trip costs? | Fine ounces, outlay, holding, sale costs and discount | Modeled break-even spot | Whether or when price will reach it |
Use one currency throughout. If fine troy ounces are not known, calculate them from gross weight and fineness first. A label or certificate is input evidence, not verification by this website.
Assumptions and limits
- No live spot price, dealer bid, buy-back policy, fee schedule or product availability is retrieved.
- The model assumes all fine ounces receive one percentage of future spot and one total selling-cost amount.
- Authenticity, assay, condition, refining deductions, minimum charges, shipment loss and dealer rejection are excluded.
- Tax treatment, inflation, currency conversion, financing and opportunity cost are excluded unless embedded in entered totals.
- The optional reference spot is descriptive and does not provide a probability or time to break-even.
- The result is not an executable bid, price target, return forecast, recommendation or financial advice.
Where to verify the inputs
Check the product’s specification or certificate for metal, gross weight, fine weight and fineness. Distinguish troy ounces from ordinary ounces and verify whether a quoted “one-ounce” product means one gross or one fine troy ounce. When in doubt, obtain an independent assay or professional appraisal rather than inferring authenticity from a listing.
For price comparisons, record source, observation time, currency, product, quantity and payment method. Dealer product prices and buy-back terms can move independently of a spot reference. Ask whether shipping, insurance, card surcharge, tax, storage, assay, refining or selling charges are included, and enter each cost only once.
The U.S. Commodity Futures Trading Commission advises physical-metals buyers to compare weight and price with spot and to account for dealer spreads and additional charges. It also notes that dealers normally sell above spot and buy below spot. Those are reasons to keep the product price, entered spot reference, separate costs and buy-back discount visible instead of compressing them into a single unexplained percentage.
Frequently asked questions
- Add product, purchase, holding and selling amounts to recover, then divide by total fine troy ounces and the modeled dealer buy-back rate.
- A 3% entered discount models gross dealer payment at 97% of a hypothetical future fine-metal spot value before separate selling costs.
- Keeping them separate makes a fixed entered selling charge visible instead of hiding it inside a percentage spread.
- It includes only the non-negative total you enter. The page does not infer storage, insurance, financing, tax or opportunity cost.
- It calculates the amount and percentage change from that manual reference to break-even. It provides no probability, timing or price forecast.
- Not necessarily. Product, quantity, condition, assay, dealer policy, fees and market liquidity can change the actual bid or cause rejection.
- No. It is the solution to one entered cost equation, not an expected future price, trade signal or recommendation.
- No. Jurisdiction-specific tax lots, disposals, reporting and currency rules are outside the model.

Compare precious-metals trading specifications separately
Physical bullion and leveraged XAU/USD or XAG/USD trading are not interchangeable. If you compare broker products, verify contract size, tick size, margin, spread, commission, financing and execution terms for the exact account and jurisdiction. Do not transfer a physical-bullion premium or buy-back assumption into a CFD calculation.
