주택 대출 EMI는 어떻게 계산되나요? ▼

대출 금액, 이자율, 기간을 기반으로 한 표준 잔액 감소 공식을 사용합니다. 이자는 매 상환마다 줄어드는 미상환 잔액에 부과됩니다.

기간이 길수록 EMI가 줄어드나요? ▼

네 — 기간이 길수록 매월 EMI는 낮아지지만 대출 기간 전체에 걸쳐 납부하는 총이자는 증가합니다. 기간이 짧으면 EMI는 높아지지만 총이자는 훨씬 적습니다.

중도 상환을 하면 어떻게 되나요? ▼

중도 상환은 미상환 원금을 줄여 총이자를 낮추고 기간을 단축할 수 있습니다. 추가 상환의 효과를 보려면 주택담보대출 상환 계산기를 사용하세요.
