What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. It's often called "interest on interest" and can make a sum grow faster than simple interest, which is calculated only on the principal amount.

The Formula:
A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]

Where:
A = Final amount
P = Principal (initial investment)
PMT = Monthly payment
r = Annual interest rate (as decimal)
n = Number of times interest compounds per year
t = Number of years

Why Start Investing Early?

Time is Your Best Friend: The earlier you start investing, the more time your money has to grow through compound interest. Even small amounts invested regularly can grow into substantial wealth over decades.

Example:
• Starting at 25: Investing $200/month at 7% for 40 years = $525,000
• Starting at 35: Investing $200/month at 7% for 30 years = $244,000

Key Benefits:
✓ Automate your savings
✓ Take advantage of dollar-cost averaging
✓ Reduce the impact of market volatility
✓ Build wealth gradually and consistently
