Example Calculation

Suppose you want to see how a $10,000 investment grows with monthly contributions and interest.

Initial Investment: $10,000
Monthly Contribution: $500
Annual Interest Rate: 6%
Investment Duration: 10 years

Step 1: Calculate Total Contributions
Total Contributions = Initial Investment + (Monthly Contribution × 12 × Years)
= 10,000 + (500 × 12 × 10)
= 10,000 + 60,000 = $70,000

Step 2: Calculate Future Value
Using the investment calculator formula, the future value comes out to approximately $91,645.50

Step 3: Calculate Total Interest
Total Interest = Future Value − Total Contributions
= 91,645.50 − 70,000 ≈ $21,645.50

This example shows that consistent contributions and compound growth can significantly increase your wealth over time.
