Hong Life CalculatorsHow it works
Cost in won = US$ price × exchange rate × (1 + VAT) × (1 + card fee). Most AI subscriptions show prices before tax; in Korea 10% VAT is added at checkout. Annual billing saves (monthly price − annual price per month) × 12, but you pay the whole year up front. The won amount moves with the exchange rate on each billing day.

FAQ
Why is my card statement different?
Card companies convert at their own rate on the posting day and may add an overseas-use fee; enter those to match your statement.
Is annual billing worth it?
Only if you are sure to use it all year — you pay twelve months up front and refunds depend on the provider’s terms.
