Roth 401(k)/IRA Growth Calculator

Project the potential growth of your Roth account and optionally compare two different scenarios side-by-side.

Back to Home

A Roth retirement account (like a Roth IRA or Roth 401(k)) is a post-tax investment vehicle. This means you contribute money that you've already paid taxes on. The key benefit is that your investments grow tax-free, and qualified withdrawals in retirement are also completely tax-free. This calculator helps you project the potential growth of your Roth account over time, assuming all contributions and growth remain in the account until retirement.

Use the 'Compare Investment Strategies' button to see two different growth scenarios side-by-side. This is useful for comparing how different contribution amounts, rates of return, or retirement ages might affect your final balance.
