What is the ROI of MYR 1,000 invested at 20% for 300 consecutive months? (UCHI Technologies Bhd)

Assuming you mean a one-time investment of MYR1,000, earning 20% annual interest compounded monthly for 300 months (25 years):

• Principal: MYR1,000
• Annual interest rate: 20%
• Monthly rate: 20% ÷ 12 = 1.6667%
• Investment period: 300 months (25 years)

Using the compound interest formula:

$$FV = P\left(1+\frac{r}{12}\right)^{300}$$ $$FV = 1000 \times \left(1+\frac{0.20}{12}\right)^{300} \approx MYR\,141,\!570$$

Results

• Final value: ≈ MYR141,570
• Profit (gain): ≈ MYR140,570
• Total ROI: ≈ 14,057%
• Growth multiple: ≈ 141.6× your original investment

A comparison over the same 25-year period:

Annual Return	Final Value (MYR)	Growth Multiple
10%	≈ 12,068	12.1×
20%	≈ 141,570	141.6×

This illustrates the dramatic effect of compounding: doubling the annual return from 10% to 20% increases the final value by more than 11 times, not just double.
