Why Roth growth is powerful

You contribute to a Roth IRA with after-tax money, and qualified withdrawals in retirement — including all the growth — come out tax-free. Over decades, the growth column usually dwarfs contributions, and none of it is taxed on the way out.

Balance = current × (1+r)ʸ + contribution × ((1+r)ʸ − 1) ÷ r

Quick FAQ

Roth vs traditional IRA?

Roth is taxed now, tax-free later; traditional is deducted now, taxed later. Roth tends to win if you expect to be in the same or higher tax bracket in retirement.

Is there a contribution limit?

Yes — the IRS sets an annual limit (with a catch-up amount at 50+) and phases out eligibility at higher incomes. Check the current year's figures before maxing out.
