計算方法

貸款機構報的是按月複息的年利率，所以月利率為 9% ÷ 12 = 0.7500%。每月供款是剛好在 240 個月內還清貸款的固定金額。

EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
= $300,000 × 0.7500% × … = $2,699

每月按尚欠金額計息，供款的其餘部分用於償還本金。所以早期供款大多是利息。

今日幣值是把第 m 個月的供款除以 (1 + 6%) 的 m/12 次方。未計入手續費、保險和提早還款罰息。

常見問題

每月供款如何計算？

月供 = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)，其中 P 是貸款額，r 是月利率（年利率 ÷ 12），n 是供款月數。

為甚麼早期供款大多是利息？

利息按尚欠金額計算，而欠款在開始時最高。隨着結餘減少，每期供款中用於償還本金的部分越來越多。

貸款年期越長越省錢嗎？

不是。年期越長月供越低，但總利息更高，而且往往高出很多。選擇前請比較兩種年期的總利息。

應該提前還款嗎？

提前還款能節省利息，而且縮短年期比減少月供省得更多。可用提前還款和還貸 vs 投資計算機與投資作比較。
