What is the gold price calculator?

This calculator estimates the KRW value of gold by purity, weight unit, and transaction type. The Korean source references international gold prices from GoldAPI.io and exchange rates from the Export-Import Bank of Korea to translate USD per troy ounce into Korean won.

It is useful for gold-bar investing, wedding-ring planning, selling old jewelry, comparing bank and jewelry-shop quotes, and checking how much of the quoted price is fee rather than metal value.

Gold forms and purity

Physical gold and jewelry

Gold bars and bullion are usually 99.99% pure and are mainly investment assets, but storage cost, transaction fees, and lower liquidity should be considered.
24K is nearly pure gold and soft; 18K contains 75% gold and is common for wedding rings; 14K contains 58.5% gold and is harder for daily wear; 10K contains 41.7% gold.
Korean jewelry weight often uses don, where 1 don equals 3.75 g. Wedding rings are often around 1 don.

Funds, ETFs, and KRX gold

Gold ETFs and funds track the gold price without requiring physical storage and can be easier to sell in small amounts.
The Korean source mentions KODEX Gold Futures(H), TIGER Gold Futures(H), KRX gold market products, and bank gold savings accounts as comparison points.
For a diversified portfolio, the guide suggests keeping gold around 5% to 10% of total assets rather than making it the entire strategy.

Worked examples

Wedding ring, bullion, and jewelry sale

Wedding ring example: 18K, 1 don, bank purchase fee 2%, gold at USD 2,350 per ounce, base value about KRW 350,000, fee KRW 7,000, final purchase about KRW 357,000.
Bullion example: 99.99% gold bar, 10 g, online exchange fee 1.5%, base value about KRW 1,000,000, fee KRW 15,000, final purchase about KRW 1,015,000.
Jewelry sale example: 14K necklace, 5 don or 18.75 g, jewelry-shop fee 3%, base value about KRW 1,370,000, fee minus KRW 41,100, final sale about KRW 1,328,900.

Trading fee and tax notes

The calculator lets users compare online gold exchanges around 1.5%, banks around 2%, and jewelry shops around 3%.
Physical gold can require safe storage and proof of purchase. Keep receipts, purity certificates, and serial numbers for later sale or inheritance reporting.
The Korean guide notes that some physical gold transactions can be VAT-exempt under conditions, while gift and inheritance tax can apply to transferred gold assets.
