1. What is the Roth IRA Calculator?

The Roth IRA Calculator estimates the future value of a Roth IRA account based on initial deposit, periodic contributions, interest rate, and compounding frequency. It helps in retirement planning by projecting tax-free growth of investments.

2. How Does the Calculator Work?

The calculator uses the Roth IRA formula:

\[ RI = AMD \times (1+R)^{(FIP \times np)} + I \times \frac{((1+R)^{(FIP \times np)}-1) \times (1+R)}{R} \]

Where:

$ AMD $ — Amount Deposited ($)
$ R $ — Rate of Interest per Annum (decimal)
$ FIP $ — Frequency of Interest Paid
$ np $ — Number of Periods
$ I $ — Periodical Fixed Amount Invested ($)

Explanation: The formula calculates compound growth of initial deposit plus the future value of periodic contributions with compound interest.

3. Importance of Roth IRA Calculation

Details: Accurate Roth IRA projections are essential for retirement planning, helping individuals understand how regular contributions and compound interest can grow tax-free over time.

4. Using the Calculator

Tips: Enter initial deposit amount, annual interest rate (as decimal), interest compounding frequency, number of periods, and periodic contribution amount. All values must be positive.
