Example of Investment Growth

Let’s assume the following:

Initial Investment: $5,000
Monthly Contribution: $500
Annual Interest Rate: 6%
Number of Years: 10

Step 1: Total Contributions = Initial Investment + (Monthly Contribution × 12 × Years)
= 5,000 + (500 × 12 × 10) = 5,000 + 60,000 = $65,000

Step 2: Future Value = Calculated using compound interest formula with monthly compounding.

Approximate future value = $90,000

Step 3: Total Interest Earned = Future Value − Total Contribution
= 90,000 − 65,000 = $25,000

This example shows that consistent monthly contributions and interest accumulation can significantly boost your wealth over time.
