An individual is considering contributing $4,000 per year to either a traditional or a Roth IRA. Payments would begin in one year. If she uses the traditional IRA, her contributions would be fully deductible. She is 40-years old and is in a 28 percent tax bracket. On either IRA she can earn 7 percent. When she retires at age 65, she believes she will be in a 15 percent tax bracket. She invests not only the $4,000 per year, but any tax savings due to the deductibility of her contributions in a taxable investment earning a pretax rate of 7 percent. She will withdraw all her money upon retirement and may owe taxes then, depending on the type of IRA chosen. What is the future value of Roth contributions?
