- Regarding your question (“i deposit $75,000 into the account on 1st Aug but registered for the promo only on 6th Aug. 1. i guess i am still considered eligible for the promotion?”), you should contact the bank, clarify & get a formal reply from the bank. (note: point#5 of T&Cs mention fresh funds)
- Bonus interest is calculated based on the incremental ADB (Average Daily Balance) compared to the a/c balance as at 31July2023 (not compared to the ADB for July).
From your given example, let’s assume you are using FastSaver a/c, has a balance of $1 as at 31July, transfer in $75k on 1st Aug from a non-CIMB bank a/c & keep until 31Aug without withdrawal.
ADB (Average Daily Balance) for Aug = $75,000
Prevailing interest for 1st $25k @ 1.5% = $25,000 * (0.015/365 * 31) = $31.85
Prevailing interest for next $25k @ 2.5% = $25,000 * (0.025/365 * 31) = $53.08
Prevailing interest for next $25k @ 3.5% = $25,000 * (0.035/365 * 31) = $74.32
Total Prevailing interest to be credited on 31 Aug = $159.25
Incremental ADB (Average Daily Balance) for Aug = $75,000 less $1 (i.e. a/c bal as at 31July) = $74,999
Bonus interest for 1st $25,000 @ (3.5% less 1.5% = 2%) = $25,000 * (0.02/365 * 31) = $42.46
Bonus interest for next $25,000 @ (3.5% less 2.5% = 1%) = $25,000 * (0.01/365 * 31) = $21.23
Bonus interest for next $24,999 @ (3.5% less 3.5% = 0%) = $0
Total Bonus interest to be credited on 20 Sep = $63.69
Grand total (prevailing interest + bonus interest) = $222.94
