Luke is a young professional in his early 30s. He is considering whether to put money in the traditional IRA or Roth IRA. This year’s IRA contribution limit for Luke is $6,000 for the combined amount of traditional and Roth contributions. Luke wants to contribute as much money to his IRA as possible. Although he knows his taxable income and his marginal income tax rate in this year, he is uncertain about his taxable income after retirement and his marginal income tax rate at that time.
