What IRA Calculator does
The IRA Calculator on Calculator.net estimates the growth of Traditional, Roth, SIMPLE, and SEP IRAs alongside regular taxable savings.

The tool outputs side-by-side comparisons of final balances, highlighting the after-tax advantage of Traditional IRAs over Roth IRAs and the after-tax advantage of Roth IRAs over taxable savings, along with a balance accumulation graph by age.
