- This version is a planning model and does not enforce annual IRS contribution limits or catch-up rules.
Why this page matters
401(k) searches are high-value because retirement planning usually needs more than a generic compound-interest page. Users want salary-based contributions and employer match in the same model.
Keeping the match cap and match percentage editable makes the page practical across different benefit plans without pretending every employer uses the same policy.
Frequently asked questions
Does this calculator use current IRS contribution limits?
No. It is a flexible planning model, so contribution levels are driven by your inputs rather than hardcoded annual limits.
Why is employer match split into rate and cap?
Because many plans match only a portion of contributions and only up to a certain salary percentage.
Is the investment return guaranteed?
No. The annual return is only an assumption for projection, not a promised outcome.
