1. What is Future Value Calculation?

The future value calculation determines how much an investment made today will grow to at a future date, given a specified interest rate and compounding frequency. It's fundamental for savings planning and investment analysis.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( FV \) — Future value of the investment
• \( PV \) — Present value or initial investment
• \( r \) — Annual interest rate (in decimal form)
• \( n \) — Number of compounding periods per year
• \( t \) — Time the money is invested for, in years

Explanation: The formula accounts for compound interest, where interest earned is added to the principal, resulting in interest on interest in subsequent periods.

3. Importance of Compound Interest

Details: Compound interest is often called "the eighth wonder of the world" because it allows wealth to grow exponentially over time. Understanding it is crucial for long-term financial planning.

4. Using the Calculator

Tips: Enter present value in dollars, annual rate as a decimal (e.g., 5% = 0.05), compounding frequency (e.g., 12 for monthly), and time in years. All values must be positive numbers.

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 the principal plus accumulated interest.

Q2: How does compounding frequency affect results?
A: More frequent compounding leads to higher returns. Daily compounding yields more than monthly, which yields more than annual compounding.

Q3: What's a typical compounding frequency for savings accounts?
A: Most savings accounts compound interest daily or monthly.

Q4: Can I use this for investments other than savings accounts?
A: Yes, this formula works for any investment with compound growth, including CDs, bonds, and some types of investment funds.

Q5: How accurate is this calculator for real-world scenarios?
A: While mathematically precise, actual returns may vary due to changing interest rates, fees, or taxes not accounted for in this simple model.
