Why a Roth IRA
You pay tax on the money before it goes in, then it grows tax-free, and qualified withdrawals after age 59½ are tax-free once the account has been open five years. You can take out your contributions (not earnings) at any time. Eligibility to contribute phases out at higher incomes, so check the IRS income limits for your filing status.
The Formulas
Roth: balance = (balance + contribution) × (1 + r)
Taxable: same, with r × (1 − tax rate)
Advantage = Roth balance − taxable balance
The taxable account is simplified: real tax depends on dividends, capital gains rates and when you sell.
Making the Most of a Roth
- •Roth accounts suit people who expect a higher tax rate in retirement
- •Contribute early in the year to give the money more time to grow
- •Roth IRAs have no required minimum distributions for the original owner
- •Earnings withdrawn early may face tax and a 10% penalty
- •You can contribute for the previous year until the tax deadline
