Project your tax-free retirement growth

Description

The Roth IRA Calculator is designed to showcase the power of tax-free compounding. By entering your current age, contributions, and expected returns, you can project how your account balance will grow over time, emphasizing the significant “tax-free growth” portion of your retirement nest egg.

Inputs

  • Current Age: Your current age.
  • Retirement Age: The age you plan to stop contributions and start withdrawals.
  • Current Balance: The amount already saved in your Roth IRA ($).
  • Annual Contribution: The total amount you plan to contribute each year ($).
  • Expected Annual Return: The average annual rate of return you expect from your investments (%).

Outputs

  • Total Balance at Retirement: The estimated final value of the account.
  • Total Contributed: The sum of all your out-of-pocket contributions (Initial + Annual sum).
  • Tax-Free Growth: The total amount of wealth generated by investment returns that can be withdrawn tax-free.

Chart

  • Growth Projection Chart: A multi-line chart comparing your “Total Balance” against your “Total Contributed” over the years.

“Good to Know”

  • Unlike a Traditional IRA, Roth IRA contributions are made with after-tax dollars, meaning your withdrawals in retirement are completely tax-free.
  • Contribution and income limits change. Verify the limit and eligibility rules for the tax year before contributing.
  • You can always withdraw your contributions from a Roth IRA at any time without taxes or penalties, though withdrawing earnings before age 59½ may trigger penalties.
