Roth 401(k) vs. Traditional 401(k) Calculator

If available in your employer's plan, the 401(k) Roth allows you to contribute to your 401(k) account on an after-tax basis - and pay no taxes on qualifying distributions when the money is withdrawn. For some investors, this could prove to be a better option than contributing on a pre-tax basis, where deposits are subject to taxes when the money is withdrawn. Use this calculator to help determine the best option for your retirement.
