About the Traditional IRA Calculator

A Traditional IRA is funded with pre-tax dollars — contributions typically reduce your taxable income today, and the balance grows tax-deferred, but withdrawals in retirement are taxed as ordinary income.

Formula: Pre-tax Balance = Current Balance × (1+r)^years + Annual Contribution × [((1+r)^years − 1) ÷ r] · After-tax Balance = Pre-tax Balance × (1 − Retirement Tax Rate)

Unlike a Roth IRA, where withdrawals are tax-free, a Traditional IRA gives you an upfront tax break now in exchange for paying tax later — it tends to favor savers who expect to be in a lower tax bracket in retirement than they are today.
