青出于蓝而胜于蓝。笨mummy introduced the OCBC bonus plus to a friend during the CNY promotion. Being a SAHM and a ex-accountant, this friend of her had devised her own plan to maximize her interest from this saving account for her household which 笨mummy would never think of. To benefit more people, 笨mummy is going to share how the plan work.

Friend and hubby opened 2 separate  accounts OCBC Bonus Plan which require a minimum monthly balance of 3k. They have 100k in their CIMB account and they would also do a incremental of 500 saving to enjoy the bonus interest of 0.8% in their CIMB account. As part of their plan, they would do doing a lump sum movement of fund from CIMB to OCBC bonus plus account 1 in Mar, and Sep and a lump sum movement to OCBC bonus plus account 2 in Jun and Dec to enjoy the bonus interest of 2.35% and the CIMB account would still be a parking account.

Total interest received = 1,373.33 and the deposit in banks = 111K + 500, and the interest rate is 1.23% which is better than parking at CIMB alone or OCBC alone (effective rate about 1.18%)
