Once you have successfully registered, your eligible DBS/POSB accounts will be automatically included in the promotion. You do not need to select or register a specific account. 

All DBS/POSB accounts are eligible, except: 

• Joint Accounts 
• Corporate Accounts 
• Fixed Deposit Accounts 
• Foreign Currency Accounts 
• Wealth Management Accounts 
• Settlement and Trust Accounts 

Balances in these excluded accounts will not count towards the qualifying increase or bonus interest calculation. 

Your bonus interest is calculated on the increase in your combined Monthly Average Daily Balance (MADB) across all eligible DBS/POSB accounts, compared with your Sep 2026 month-end balance. You must maintain an increase of at least S$10,000 to qualify for that month. Bonus interest is calculated on the qualifying increase, capped at S$1,000,000.

For example: If your total Sep 2026 month-end balance across all eligible accounts was S$20,000 and your combined MADB for the month was S$70,000, your bonus interest would be calculated on the S$50,000 increase.

Your total Sep 2026 month-end balance is the baseline used to calculate your qualifying increase. Simply add the September 2026 month-end balances of all your eligible DBS/POSB accounts.  

You can find these balances in your Sep 2026 consolidated statement on the digibank app. 

1. Log in to the digibank app. 
2. On the Home screen, tap Deposits. 
3. Select any eligible DBS/POSB account. 
4. Tap View eDocuments. 
5. Open your Sep 2026 consolidated statement and add the month-end balances of all your eligible DBS/POSB accounts. 

Your combined Monthly Average Daily Balance (MADB) is calculated across all your eligible DBS/POSB accounts. For each day of the month, the end-of-day balances across these accounts are added together. These daily combined balances are then totalled and divided by the number of days in that month.

For example: If the combined end-of-day balance across all your eligible accounts is S$20,000 for 15 days and S$40,000 for the remaining 15 days of a 30-day month, your combined MADB is S$30,000: [(S$20,000 × 15) + (S$40,000 × 15)] ÷ 30.

Your total bonus interest earned during the promotion will be credited as a lump sum by 28 Feb 2027 to the eligible DBS/POSB account with the highest ending balance on 31 Dec 2026. If two or more eligible accounts have the same highest ending balance, DBS/POSB will determine which account to credit the bonus interest to.
