Calculator methodology
Dollar-cost averaging into gold: calculator and limits
Estimate accumulated ounces and average cost from recurring dollar purchases while accounting for price and premium assumptions.
What changed
The calculator now accepts a sequence of period prices and reports total ounces plus weighted average cost per ounce.
Why it matters
A fixed dollar contribution buys more ounces at lower prices and fewer at higher prices. That behavior reduces timing concentration but can lag a lump sum in a steadily rising market.
- Use delivered prices, not spot alone.
- Keep contribution intervals consistent.
- Include cash drag if money waits between purchases.
- Compare against an explicit alternative.
Historical context
Precious-metals markets mix a globally traded raw material, manufactured investment products, and retail distribution. The price of the metal and the price a buyer actually pays can therefore diverge for long periods.
What could change the conclusion
A periodic plan can be operationally expensive for small physical purchases. Larger, less frequent transactions may reduce per-ounce premiums and shipping.
Reproducible by design
Methodology and limitations
- Period ounces = net contribution ÷ all-in price per ounce.
- Average cost = total contributions ÷ total ounces.
- No return is shown unless a separate current liquidation bid is supplied.
