[問題] 利息算法

[kicksmile (暈)]

我在BMW官網上看到他們的車貸利息

1.9% APR for 36 months available through 2/28/2011. $28.60 per $1,000.
Also available, 2.9% APR for 37-60 months. $17.92 per $1,000.
3.9% APR for 61-72 months. $15.60 per $1,000.

我看不懂的是為什麼利息per1,000會越來越低,利息不是應該越來越高嗎(1.9%-3.9%)?

→ viking0518:月份也不同啊,3.9%的給你拉長到61-72個月
→ supa:那個應該是每個月繳多少吧
→ supa:36 * 28.6 = 1029.6, $29.6才是利息吧
