How United States gold prices are calculated on this page
Source. The international XAU/USD spot price comes from gold-api.com's historical archive (London PM-fix benchmark). The USD/USD exchange rate comes from exchangerate-api.com's 2018 year-end snapshot.
Conversion. Every USD figure on this page is computed as XAU/USD price × USD/USD rate. We use the year-end exchange rate consistently across all March 2018 prices on this page.
Per-unit math. Per-gram = per-ounce ÷ 31.1035. Per-tola = per-gram × 11.664. Per-10g = per-gram × 10. Per-kilo = per-gram × 1000. Karat values multiply per-gram by the purity ratio (24K = 0.999, 22K = 0.916, 21K = 0.875, 18K = 0.750, 14K = 0.585, 10K = 0.417).
What this page does NOT include. Local sales tax / VAT, customs duty on imports, dealer making charges, jewellery design premiums, or coin numismatic premiums. To go from this pure-metal value to a final retail rate in United States, add the country-specific levies described in the “United Statesgold market” section above.

How was the local currency price calculated?
USD prices on this page are computed from the verified international XAU/USD spot price for March 2018 (sourced from gold-api.com), multiplied by the 2018-end USD/USD exchange rate from exchangerate-api.com. We use year-end rates as a single reference point for the entire month — for most stable currencies the within-year FX drift is small, but during currency crises (PKR 2022–23, TRY 2022, ARS 2024 etc.) the actual mid-month rate may differ.
Why does the retail price in shops differ from this number?
The $ figures here represent the international gold spot price converted to USD at the 2018-end exchange rate. United States's retail jewellers add (1) import duties and sales tax (varies by SKU and karat), (2) dealer making charges (typically 3–12% of metal value), and (3) a small premium for purity certification on bars. Always verify the exact day's retail rate with a reputable local dealer before transacting.
