Frequently asked questions

How does an employer match work?

The employer adds a percentage of your salary up to a limit, usually when you also contribute. The match is part of your total contributions.

Are there contribution limits?

Yes, the IRS sets annual limits that change over time. Check the IRS site for the current figure.

Does this model salary growth?

No. It assumes steady contributions, so results are an estimate.
