Why a dollar estimate can change when the won price stays the same
Read the price check date and exchange rate date separately. A verified ₩2,400 example shows how K-Tracker calculates an approximate USD price.
Start with the recorded won price
K-Tracker shows a recorded price in Korean won and an approximate amount in another currency. They answer different questions: what price was recorded at the source, and what that amount is roughly worth in your currency. On 2026-11-15, the Sprite 500ml CU product page showed ₩2,400 and approximately US$1.80. This is a dated example, not a promise of the price or stock at the branch you visit.
The calculation behind US$1.80
The exchange rate response checked on 2026-11-15 used KRW as its base and listed USD at 0.000748 per won. The response reported its last update as 2026-11-15 00:02:32 UTC. For this example, ₩2,400 × 0.000748 USD/KRW = US$1.7952, rounded to US$1.80. K-Tracker’s stored rate date was also 2026-11-15. A source update time and the date a site checks or stores a rate describe different events.
Compare prices and dates together
If a later rate changes while the recorded won price stays at ₩2,400, the dollar estimate can change without the product becoming cheaper in Korea. Compare the won amounts and their price check dates first. Then check the exchange rate date before comparing converted amounts. This product had one recorded day, 2026-11-15, when checked; one observation cannot establish a price trend or a 90-day low.
Use the estimate to plan, then check the purchase
The converted amount is a planning reference, not a card charge quote. Your payment provider’s rate and any fees can produce a different total. Check the seller’s current price, exact size and promotion conditions before paying. The CU page also carried a 1+1 label: the ₩2,400 used here is the recorded single-item price, not an automatically halved price. Multi-buy conditions and quantities remain separate from currency conversion. Reopen the linked product page for its latest recorded price and both dates.
