How to maximize savings returns?

The key to wealth accumulation is utilizing the compound interest effect. In the current market, specific short-term deposits (1-2 years) often yield better annual returns than long-term commitments due to rate fluctuations. Prioritize tax-advantaged accounts (ISA, IRP) before standard savings.

1 How to Use

  1. Select Savings Type Choose Monthly Savings if you plan to deposit a fixed amount every month. Choose Lump Sum if you are depositing a large amount at once.
  2. Input Amount & Rate Enter your target deposit amount and the annual interest rate offered by your bank.
  3. Check Result The calculator will show your "After-tax Maturity Amount" subtracting the standard 15.4% interest tax.
