This calculator provides estimates for educational purposes only. Results are based on the inputs you provide and standard financial formulas. They do not constitute financial, investment, tax, or legal advice. Consult a qualified professional before making financial decisions.
The IRS elective deferral limit is $23.500 for 2025. If you're 50 or older, you can contribute an extra $7500 as a catch-up contribution, for a total of $31.000. This calculator automatically caps your contribution at the correct limit for your age each year.
A common formula is "50% match up to 6% of salary" — meaning your employer contributes 50 cents for every dollar you contribute, up to a maximum employer contribution of 3% of your salary (50% of the 6% ceiling). Formulas vary by employer; check your plan documents for the exact terms.
Essentially yes — it's compensation your employer only pays if you contribute enough to claim it. Contributing at least up to the full match is one of the highest-return moves in personal finance, since it's an instant, guaranteed return that no market investment can match.
This depends on your plan's vesting schedule. Some employers vest matching contributions immediately; others require several years of service before you fully own them. This calculator assumes full vesting — check your plan for your actual schedule.
No. This is an estimate based on the return, salary, and contribution assumptions you enter — not a guarantee. Market returns vary year to year, and past performance doesn't predict future results.
