Problem

With gold prices hitting record highs, more investors in their 50s are turning to gold, but most are unaware that taxes differ completely depending on the trading channel. KRX gold market (capital gains tax exempt), physical gold from jewelry stores (10% VAT + capital gains tax), gold banking (15.4% dividend tax), gold ETFs (dividend or capital gains tax) — selling the same 100 million KRW (approx. $75,000) worth of gold can result in after-tax proceeds differing by several million KRW. There is also little awareness of how to transfer physical gold purchased from jewelry stores to the KRX market.

Solution

On the web, enter (1) purchase channel, (2) purchase amount/timing, and (3) current valuation of your gold holdings to compare taxes, fees, and net proceeds across channels at a glance. It also suggests conversion scenarios like 'Converting your jewelry store physical gold to KRX now saves X KRW in taxes' and calculates the impact on comprehensive financial income taxation.

Target: Retirement planners aged 50-60 holding physical gold or gold banking of 5 million KRW (approx. $3,750) or more, considering when to sell.
Revenue Model: Basic comparison free, optimal selling strategy report per transaction 5,900 KRW (approx. $4.43), KRX conversion guide paid content 9,900 KRW (approx. $7.43)
