Formel

FV = PV × (1+r)ⁿ + PMT × [(1+r)ⁿ − 1] / r
Roth After-Tax = FV (no tax at withdrawal)
Traditional After-Tax = FV × (1 − withdrawal tax rate)
PV = Current balance
PMT = Annual contribution
r = Annual return rate
n = Years to retirement

A Roth IRA grows tax-free and qualified withdrawals in retirement are not taxed. This makes it especially powerful for younger investors who expect to be in a higher tax bracket at retirement. The 2024 annual contribution limit is $7,000 ($8,000 for those 50+). Learn more at IRS.gov Roth IRA.
