Example:
Assume mortgage loan amount of HK$4,000,000 with loan tenor of 20 years and mortgage interest rate at 3.25%* p.a.:
CONVENTIONAL PRIME-BASED MORTGAGE PLAN WITH MORTGAGE DEPOSIT LINKED FEATURE
| STANDARD CONVENTIONAL PRIME-BASED MORTGAGE PLAN WITH DEPOSIT UNDER SAVING ACCOUNT
| |
|---|---|---|
| Initial deposit | HK$500,000 | |
| Deposit rate (p.a.) | 3.25% | 0.001% |
| Total mortgage interest expense (A) | HK$1,444,715 | HK$1,444,715 |
| Total deposit interest earned (B) | HK$362,949 | HK$100 |
| Net interest expense (A) – (B) | HK$1,081,766 | HK$1,444,615 |
| Difference on net interest expenses | HK$362,849 (25% less) | |
The above example is based on the assumptions below and does not take into account any fees and any interest rate change which is for reference only.
* Based on the Hong Kong Dollar Prime Rate of Standard Chartered Bank (Hong Kong) Limited (the "Bank") (5.375%p.a. as of 22 September 2025) minus 2.00%pa.
