Compound Interest Formula — How It Works
Example: You invest KES 100,000 in a Kenyan money market fund at 9.4% compounded daily for 5 years. Your final amount is 100,000 × (1 + 0.094/365)365×5 = KES 159,564. Interest earned is KES 59,564 — compared to KES 47,000 from simple interest. That extra KES 12,564 came from your interest earning interest.
The more frequently interest compounds, the faster your money grows. Daily compounding (n=365) beats annual compounding (n=1) because interest is reinvested every single day. This is why Kenyan money market funds, which compound daily, produce higher returns than fixed deposits which typically use simple interest.
