Fidelity Investments Inc. Thursday unveiled an on-line tool aimed at helping investors make decisions about setting up individual retirement accounts.

Found on Fidelity's Web site at, the IRA Evaluator allows investors to plug in information about their earnings and withholding to determine whether they are eligible for the Roth IRA or for the traditional IRA.

The tool enables the investor to compare hypothetical investment outcomes for each IRA, a spokesman for Boston-based Fidelity said.

"It doesn't tell the person which way to go, but it gives them information to aid their decision," he said.

The Roth IRA was created by the Taxpayer Relief Act of 1997 and features tax-free earnings growth and higher income thresholds. It is set to roll out in January.
