1. What is a Roth Calculator?

Definition: This calculator estimates the future value of investments in a Roth IRA account based on principal amount, annual return rate, and investment time.

Purpose: It helps investors plan their retirement savings by projecting how their Roth IRA contributions might grow over time.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( FV \) — Future value (USD)
• \( P \) — Principal investment amount (USD)
• \( r \) — Annual return rate (decimal)
• \( t \) — Investment time (years)

Explanation: The formula calculates how your initial investment grows with compound interest over time.

3. Importance of Roth IRA Planning

Details: Roth IRAs offer tax-free growth and withdrawals in retirement. Understanding potential growth helps with retirement planning and contribution decisions.

4. Using the Calculator

Tips: Enter your initial investment (principal), expected annual return rate (default 7%), and number of years you plan to invest (default 10). All values must be > 0.
