Weighted, not simply averaged
Adding prices and dividing by the row count ignores how much metal each row acquired. This model divides total entered asset spend or cash outlay by total acquired units.
Precious Metals Average Cost Calculator
Combine entered gold and silver purchase rows into separate metal quantities, cash outlays and all-in average costs per troy ounce—with an optional current-price scenario.

How the precious metals average cost is calculated
Row metal spend = purchased ounces × entered price per ounce
Row cash outlay = metal spend + entered premium, fee or cost
Metal all-in average cost = total metal cash outlay ÷ total metal ounces
Entered current value = metal ounces × separately entered current price
Enter the metals purchases
Add up to 24 purchases. Record ounces, price per troy ounce and any premium, fee or other cost in one display currency.

What does this calculator answer?
It answers: “Across these entered purchases, how many troy ounces of gold and silver do I have, how much cash did I enter as spent, and what is each metal’s all-in average cost per ounce?” It preserves separate XAU and XAG summaries and can compare them with two separately entered current prices. It does not combine gold and silver into a meaningless blended ounce price.

The arithmetic uses troy ounces because gold and silver reference prices are normally expressed per troy ounce. One troy ounce is exactly 31.1034768 grams. Gold market conventions refer to fine troy ounces, while silver is quoted per troy ounce. Enter the fine-metal quantity that actually belongs in your record rather than assuming that package weight, gross weight and fine-metal content are interchangeable.
Costs stay visible
Premiums, commissions, shipping or other entered costs add cash outlay without adding ounces. The metal-only and all-in averages therefore answer different questions.
No hidden market data
Every purchase and current price is typed by the user. The tool does not silently mix delayed prices with historical rows or present a stale quote as current.
Worked example from the audited fixture
Reproduce it with “Load audited example”The audited example enters 0.20 gold ounces at USD 2,500 plus USD 10, 0.10 gold ounces at USD 2,700 plus USD 5, 20 silver ounces at USD 30 plus USD 15, and 10 silver ounces at USD 32 plus USD 10. Gold outlay is USD 785 for 0.30 oz, so its all-in average is USD 2,616.67/oz. Silver outlay is USD 945 for 30 oz, so its all-in average is USD 31.50/oz. Total outlay is USD 1,730. At entered current prices of USD 2,650 gold and USD 31 silver, current scenario value is USD 1,725, or USD 5 below entered outlay.
How to interpret the result
The result is an arithmetic record of only the rows and costs entered. It is not a tax lot ledger, realized-gain calculation, dealer valuation, live quote or investment recommendation. Gold and silver remain separate because their ounce quantities and prices cannot be averaged into one meaningful per-ounce figure.
Enter purchases consistently
- Choose one display currency. Convert records before entering them if purchases were made in different currencies; this calculator performs no exchange-rate conversion.
- Use troy-ounce quantities and per-troy-ounce prices. Do not mix grams, avoirdupois ounces, lots, coins or bar counts unless you first translate them into the fine-metal troy ounces represented.
- Record the cash-cost boundary. Include only premiums, fees, shipping or other acquisition costs you intend the all-in average to contain. Do not enter the same amount in both the unit price and the extra-cost field.
- Keep current prices separate. Optional current-price inputs affect only the scenario-value section; they never rewrite purchase history or average cost.
- Reconcile the result with source documents. Receipts, statements, dealer confirmations and custody records remain the source of truth.
Recordkeeping boundary“Average cost” here is descriptive purchase arithmetic. Jurisdictional tax-basis rules, identification methods, disposals, wash-sale rules, foreign exchange, collectibles treatment and reporting requirements are outside the model.
Assumptions and limitations
- Prices, contributions, acquired units and costs are user-entered and are not verified against a broker, exchange, receipt or custody statement.
- Gold and silver can be held as physical metal, exchange-traded products, futures, CFDs or other contracts. This page models entered metal quantities and cash only; it does not infer product rights, leverage, financing or counterparty exposure.
- Physical products may include premiums, dealer spreads, shipping, storage, insurance, assay, fabrication and tax. Only the additional costs entered in each row are included.
- A dealer’s sell-back price can be below a displayed spot reference. The optional current-price scenario does not estimate a bid price, spread or executable proceeds.
- DCA changes the timing and quantities of purchases but does not remove market risk, guarantee a lower average, or establish that a schedule will outperform a lump-sum purchase.
- The tool supports at most 24 rows in one browser calculation. It does not store records after the page is closed.

Frequently asked questions
How is precious metals average cost calculated?
For each metal, add entered purchase price times ounces plus entered row costs, then divide that metal’s total cash outlay by its total troy ounces.
Why are gold and silver averages separate?
A gold ounce and a silver ounce have different prices and economic meaning. The calculator summarizes each metal separately and combines only total cash outlay and entered current value.
Is this a tax cost-basis calculator?
No. It is descriptive entered-purchase arithmetic. Tax lots, disposals, currency rules and jurisdiction-specific basis methods are not calculated.
Should premiums and fees be included?
Enter the premiums, fees or other acquisition costs you want represented in all-in average cost. Leave a row at zero if its unit price already includes every intended cost.
Does the calculator use live gold or silver prices?
No. Current prices are optional manual scenario inputs. The page retrieves no quote and does not label an entered price as live.
Can I mix currencies in the purchase rows?
No. Convert every row into one display currency before entry. The three-letter code changes labels only and performs no exchange-rate conversion.
Can I enter grams instead of troy ounces?
Convert fine-metal grams to troy ounces first. The LBMA conversion is one troy ounce equals exactly 31.1034768 grams.
Does a positive scenario difference mean I can sell for that amount?
No. It compares entered ounces with entered current prices before unentered dealer spread, selling fees, tax, storage, execution and product-specific terms.
