1. What is Compound Growth?

Compound growth refers to the process where an investment earns interest not only on the initial principal but also on the accumulated interest from previous periods. This creates exponential growth over time, making it a powerful concept in finance and investment.

2. How Does the Calculator Work?

The calculator uses the compound growth formula:

Where:

• \( FV \) — Future Value (currency)
• \( PV \) — Present Value (currency)
• \( r \) — Interest rate (as decimal)
• \( t \) — Number of time periods

Explanation: The formula calculates how much an investment will grow over time when interest is compounded. The (1 + r)^t term represents the compounding effect over multiple periods.

3. Importance of Growth Calculation

Details: Understanding compound growth is essential for financial planning, investment decisions, retirement planning, and comparing different investment opportunities. It demonstrates the time value of money and the power of long-term investing.

4. Using the Calculator

Tips: Enter present value in your preferred currency, interest rate as a percentage (e.g., 5 for 5%), and the number of compounding periods. All values must be valid (present value > 0, rate ≥ 0, periods ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both principal and accumulated interest, leading to exponential growth.

Q2: How often should interest be compounded?
A: More frequent compounding (daily, monthly) results in higher returns. This calculator assumes compounding occurs once per period.

Q3: Can this calculator handle different compounding frequencies?
A: This version assumes annual compounding. For different frequencies, adjust the rate and time accordingly (e.g., for monthly compounding, divide annual rate by 12 and multiply years by 12).

Q4: What is the Rule of 72?
A: The Rule of 72 estimates how long it takes for an investment to double: 72 ÷ interest rate = years to double. It's a quick mental calculation based on compound growth.

Q5: Are there limitations to this calculation?
A: This assumes constant interest rates and no additional contributions or withdrawals. Real-world investments may have variable rates and cash flows.
