Singapore Gold Price Calculator
Use this calculator to estimate gold value by gram weight and purity. The calculation updates as you change inputs.
Weight and purity
Calculations depend on precise inputs
Gold value changes with grams, purity, premium, and spread. That is why the calculator shows a clear estimate, not a shop quote.
Formula used
How the calculation works
The base calculation converts the USD per troy ounce gold price into SGD per gram:SGD per gram = (USD per oz x USD/SGD) / 31.1034768. After that, purity values such as 916 or 999 are multiplied by their purity factor.
What is not included
This estimate does not include buy/sell spread, premiums, jewellery making charges, refining costs, possible taxes, platform charges, or shop-specific decisions.
Estimate limits
Prices are shown as indicative estimates. They help with an initial calculation, but actual transaction prices still need to be confirmed with the relevant shop, platform, or adviser.
Price records and freshness
Price records show recent changes and keep old numbers from looking like current prices. If a price is not fresh enough, the indicative label remains so readers do not mistake it for a live quote.
