1. What is Compound Growth?

Compound growth refers to the process where an investment grows exponentially over time as earnings are reinvested to generate additional earnings. The formula calculates how money grows when returns are compounded.

2. How Does the Calculator Work?

The calculator uses the compound growth formula:

Where:

• \( FV \) — Future value of the investment
• \( P \) — Principal investment amount
• \( r \) — Annual growth rate (in decimal)
• \( n \) — Number of years the money is invested

Explanation: The formula accounts for exponential growth where each period's growth builds on the previous period's total.

3. Importance of Compound Growth

Details: Understanding compound growth is crucial for financial planning, investment analysis, and retirement planning. It demonstrates how small, regular investments can grow significantly over time.

4. Using the Calculator

Tips: Enter principal amount in USD, growth rate as a decimal (e.g., 0.05 for 5%), and number of years. All values must be valid (principal > 0, rate ≥ 0, years > 0).

5. Frequently Asked Questions (FAQ)

Q1: How is compound growth different from simple growth?
A: Compound growth earns returns on both the principal and accumulated returns, while simple growth only earns returns on the original principal.

Q2: What's a realistic growth rate to use?
A: Historically, stock markets average 7-10% annually, but this varies by asset class and time period. Conservative estimates are often 4-6% after inflation.

Q3: How often is the compounding assumed to occur?
A: This calculator assumes annual compounding. For more frequent compounding, the formula would need adjustment.

Q4: Can this be used for debt calculations?
A: Yes, the same formula applies to compound interest on loans or credit cards, where r would be the interest rate.

Q5: How does inflation affect these calculations?
A: For real (inflation-adjusted) growth, use a real rate of return (nominal rate minus inflation rate).
