Calculator workbench

Instant estimates
01

Metal value, melt value, and unit conversion

Convert gross weight to fine troy ounces before applying spot.

Fine metal0.9999 oz t31.1035 g grossEstimated melt value$4,399.561 gross troy oz
02

Dealer premium

Compare an all-in retail price with the melt estimate above.

Dollar premium$250.44Premium over melt5.69%Negative means below estimated melt
03

Dollar-cost averaging

Enter one all-in price per period, separated by commas.

Total contributed$1,500.006 periodsOunces accumulated0.3518 oz tAverage cost$4,264.30/oz
04

Inflation-adjusted gold price

Restate a historical price using two CPI index values.

Equivalent current dollars$2,267.39Price × current CPI ÷ historical CPI
05

Simple real-yield estimate

A planning estimate, not the observed TIPS real yield.

Approximate ex-ante real yield1.85%Positive real-yield estimate
06

Gold-to-silver ratio

Use prices from the same source, currency, and timestamp.

Gold-to-silver ratio67.69One ounce of gold equals 67.69 ounces of silver at these inputs

Estimates exclude taxes, assay adjustments, bid/ask spreads, shipping, storage, insurance, and product-specific marketability unless you include them in your inputs.

01

What changed

Seven related calculations now share one workbench so a user can move from metal content to delivered premium, recurring purchase cost, inflation adjustment, and macro context without re-entering basic assumptions.

02

Why it matters

Unit mistakes, gross-versus-fine weight, hidden fees, and inconsistent spot timestamps can create larger errors than a small price move.

  • Value by weight and purity.
  • Melt value and dealer premium.
  • Grams, kilograms, pennyweight, tola, and troy ounces.
  • Dollar-cost-average ounces and cost basis.
  • Inflation adjustment and simple ex-ante real yield.
03

Historical context

A troy ounce is about 31.1034768 grams and differs from the avoirdupois ounce used for many everyday goods. Bullion fineness describes precious-metal content in parts per thousand.

04

What could change the conclusion

Actual settlement value can differ because of assay results, product premium, taxes, shipping, payment method, spreads, and the exact price timestamp.

Reproducible by design

Methodology and limitations

  1. Fine troy ounces = gross weight in troy ounces × fineness ÷ 1,000.
  2. Melt value = fine troy ounces × spot price.
  3. Simple real yield estimate = nominal yield − expected inflation; it is not an observed TIPS yield.
