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.
Gold DCA Calculator
Calculate how many troy ounces an entered gold dollar-cost-averaging schedule acquires, then compare metal-only and all-in average cost per ounce.

How the gold DCA calculation works
Metal spend = contribution, or contribution − entered cost when costs are inside the budget
Ounces acquired = metal spend ÷ entered price per troy ounce
Total cash outlay = contribution + entered cost when costs are added
Metal-only average = total metal spend ÷ total ounces
All-in average cost = total cash outlay ÷ total ounces
Enter the gold contribution rows
Use one row per contribution. Equal cash amounts represent the standard DCA pattern; different amounts remain visible as a variable-cash schedule.

What does this calculator answer?
It answers: “Under these entered contribution amounts, purchase prices and costs, how many gold troy ounces are acquired and what is the resulting weighted average cost?” Equal cash contributions are labelled an equal-cash schedule. If the amounts differ, the arithmetic still runs but labels the plan variable-cash instead of silently calling it standard DCA.

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”Enter three equal USD 500 contributions at USD 2,500, USD 2,750 and USD 2,250 per gold troy ounce, with USD 5 of costs added to each purchase. The rows acquire 0.20 oz, 0.181818 oz and 0.222222 oz. Total gold is 0.604040 oz, contributions are USD 1,500, entered costs are USD 15 and total outlay is USD 1,515. The metal-only weighted average is USD 2,483.28/oz and the all-in average cost is USD 2,508.11/oz. At an entered current price of USD 2,600, scenario value is USD 1,570.51.
How to interpret the result
The all-in average is total entered cash outlay divided by acquired ounces. It can be above the metal-only average because premiums and fees add cash without adding metal. A result below the simple mean of the entered prices is a mechanical consequence of buying more ounces at lower entered prices; it is not evidence that DCA will outperform another purchase plan.
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.
DCA definition used hereInvestor.gov describes dollar-cost averaging as investing equal portions at regular intervals regardless of market movements. This page checks equal cash amounts but does not verify dates or regularity. Different amounts are calculated as a variable-cash accumulation schedule.
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
What is dollar-cost averaging?
Investor.gov defines it as investing equal portions at regular intervals regardless of market movements. This page checks equal cash amounts but does not verify dates or regularity.
How is the DCA average price calculated?
Each contribution is divided by its entered per-ounce price to calculate ounces. Total metal spend divided by total ounces gives the metal-only weighted average.
What is the all-in average cost?
It is total entered cash outlay divided by total acquired ounces. Added premiums or fees can make it higher than the metal-only average price.
What changes when costs come out of the contribution?
The entered row cost reduces cash available to buy metal, so acquired ounces are lower while the contribution remains the row’s total cash outlay.
Why can the weighted average differ from the simple average price?
Equal cash buys more ounces at lower prices and fewer at higher prices. A simple average gives every price row equal weight regardless of acquired quantity.
Does DCA guarantee a profit or lower average cost?
No. Results depend on the entered price path and costs. The calculator makes no claim about future prices, performance or comparison with lump-sum investing.
Does this page retrieve the current gold price?
No. Every price is entered manually. The optional current price produces one scenario value and is not a quote or forecast.
Can I enter different contribution amounts?
Yes. The calculator will label them a variable-cash schedule so the result is not silently presented as the equal-cash DCA pattern.
