Albert Einstein reportedly called compound interest the eighth wonder of the world. For Malaysian savers, understanding compound interest is the difference between building wealth slowly and building it exponentially. Here is a clear explanation with real Malaysian numbers.
What Is Compound Interest?
Simple interest earns returns only on your original principal. Compound interest earns returns on your principal AND on your previously earned returns. The longer the time horizon, the more dramatic the difference.
Where: P = principal, r = annual rate, n = compounding periods per year, t = years

Daily vs Monthly vs Annual Compounding
The more frequently interest compounds, the higher your returns. Daily compounding (used by some digital savings accounts) yields slightly more than monthly, which beats annual. For EPF, dividends compound annually when reinvested.
The Power of Starting Early
Amir invests RM500/month from age 25 to 35 (10 years, RM60,000 total) at 5.5%, then stops. Budi invests RM500/month from age 35 to 55 (20 years, RM120,000 total) at 5.5%. At age 55: Amir has RM241,000. Budi has RM214,000. Amir wins — investing half as much but starting 10 years earlier.
