银行利息是否算错啦!

spongebob_2

五月底开通了CIBC的BONUS SAVINGS ACCOUNT
并存入5000元，
前二天（7月4号）查只发现多了0.5元利息，存了一个多月就这点利息吗？
搞不懂咋算的？

请各位大侠指点！谢谢！！

看看小字，一个月中每天的结余存款额要至少5000，并且还要高于每月第一天的结余存款额，而且利率也低才3%

Bonus interest will be earned in a month if, throughout the month: (I) each day's final balance is always at least $5,000, and (ii) each day's final balance is always the same as or greater than the opening balance on the first calendar day of the month. When the account meets both requirements for a month, interest is calculated on each day's final balance using the interest rate that applies to the tier into which the final daily balance falls. If both requirements are not met, no bonus is earned that month; instead, for any day when the final balance is $5,000.00 or more you will earn the rate that applies to the tier into which the final daily balance falls, minus the bonus interest rate shown on the last line above. The time-limited 3/4% bonus is in lieu of the standard bonus interest paid on the account when you meet the bonus criteria; the standard bonus applies after June 2006.
