1. What is the IRA Growth Calculator?

The IRA Growth Calculator estimates the future value of your retirement account using the compound interest formula. It helps you project how your investments might grow over time based on your contributions and expected returns.

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 growth, where interest is earned on both the initial principal and accumulated interest.

3. Importance of Compound Interest

Details: Compound interest is the most powerful force in wealth building. Even small differences in interest rates or compounding frequency can lead to significant differences in final account value over long periods.

4. Using the Calculator

Tips: Enter your current IRA balance, expected annual return (as decimal), how often interest compounds (typically 12 for monthly), and years until retirement. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between annual and monthly compounding?
A: Monthly compounding (n=12) grows money faster than annual compounding (n=1) because interest is calculated and added more frequently.

Q2: What's a realistic rate of return for an IRA?
A: Historically, stock market returns average 7-10% annually (0.07-0.10 decimal), but your actual returns may vary.

Q3: Should I include contributions in this calculation?
A: This calculator shows growth of existing funds only. For contribution projections, use a more comprehensive retirement calculator.

Q4: How does inflation affect these results?
A: These are nominal returns. For real (inflation-adjusted) returns, subtract expected inflation from your rate.

Q5: What compounding frequency should I use?
A: Match your actual investments - most mutual funds compound daily (n=365), while some accounts compound monthly (n=12) or quarterly (n=4).
