Silver Price Methodology & Formulas

Silver pricing follows the same structure as gold: we begin with USD-quoted XAG/oz spot, normalize to grams, convert to common units, and translate to local currencies using mid-market FX. This article provides the derivation, examples, and presentation standards.

1. Inputs & Context

We track internationally quoted silver spot in USD per troy ounce and convert to grams using the same troy standard (31.1034768 g/oz). For background, see Silver as an investment and LBMA Good Delivery (Gold list as standard).

  • Silver spot (USD/oz): Poz,USD
  • FX rate: FXUSD→CCY mid-market (see FX methodology)
  • UTC timestamps on inputs and UI

2. Equations

Pg,USD = Poz,USD ÷ 31.1035

Punit,USD = Pg,USD × funit (see Units)

Punit,CCY = Punit,USD × FXUSD→CCY

3. Worked Example

Assume Poz,USD=28.00 and FXUSD→EUR=0.9200:

  • Per gram (USD): 28 ÷ 31.1035 = 0.900
  • Per gram (EUR): 0.900 × 0.9200 = 0.828

4. Notes & Caveats

Silver Purity/types:

Unlike gold, silver is typically not classified by karats. Instead, silver purity is usually expressed as a percentage or parts per thousand. The most common purities are:

  • Fine Silver (99.9%): Used in investment-grade bullion, coins, and bars.
  • Sterling Silver (92.5%): Common in jewelry, silverware, and decorative items.
  • Coin Silver (90%): Previously used in coins, now less common.
  • Other Alloys: Lower purity silver used in budget or industrial applications.

Silver purity is often marked with stamps like "999," "925," or "900" to indicate the purity level.
