Why Use a Roth IRA?

A Roth Individual Retirement Account (Roth IRA) is one of the most powerful retirement savings vehicles available in the United States. Unlike traditional IRAs, contributions to a Roth IRA are made with after-tax dollars. This means that the funds in your Roth IRA grow completely tax-free, and qualified withdrawals during retirement are also 100% tax-free.

Compounding Growth Mechanics

The future balance of a Roth IRA is built on the power of annual compounding. If contributions are made at the beginning of each year, the balance grows according to the following recurrence relation:

Where:

• B_t is the balance at the end of year t.
• B_t-1 is the balance at the end of the previous year.
• C is the annual contribution amount.
• r is the expected annual rate of return (expressed as a decimal).

Roth IRA Benefits & Rules

To maximize your Roth IRA wealth accumulation, keep these key rules and guidelines in mind:

• Contribution Limits: The IRS sets annual contribution limits. For example, the contribution limit is $6,500 for tax year 2023 and $7,000 for tax year 2024, with an additional $1,000 catch-up contribution permitted for savers aged 50 and older.
• Income Limits: Eligibility to contribute directly to a Roth IRA phases out at higher income thresholds. High earners may need to utilize the Backdoor Roth IRA strategy to contribute.
• Tax-Free Payouts: Withdrawals of earnings are tax-free and penalty-free once you reach age 59 and a half, provided the account has been open for at least five years. You can withdraw your original contributions at any time without taxes or penalties.
