Equal monthly installment (원리금균등) formula. The rate is the one you entered — this tool does not assume what a Korean lender would offer you. Actual bank quotes may differ slightly and may add fees or early-repayment charges. Dollar figures convert at ₩1,332.1/USD, the Korea Eximbank reference rate quoted 2026-10-20. Your own bank will not give you that rate.
