Frequently Asked Questions
Answers to popular questions about pre-tax contributions, matches, and vesting rules.
Q.What is a 401(k) employer match limit?
An employer match limit is the maximum share of your salary your employer will match. For example, if they offer a 50% match up to 6% of your salary, and you earn $100,000, they will match half of your contributions up to an employee deposit of $6,000, making the maximum employer contribution $3,000.
Q.How does a vesting schedule affect my 401(k) balance?
A vesting schedule determines how much of your employer's matched contributions you legally own. If you leave the company before becoming fully vested, you will forfeit the unvested portion. Your own contributions are always 100% vested and cannot be taken back.
Q.How does inflation impact my retirement savings?
Inflation reduces the future purchasing power of your money. A nominal balance of $1,000,000 in 30 years might only buy what $450,000 buys today at a 2.5% inflation rate. Adjusting for inflation helps you understand the real purchasing power of your nest egg.
Q.What are the catch-up contributions for age 50 and older?
The IRS allows employees aged 50 and above to make extra pre-tax contributions beyond the baseline annual limits. This "catch-up contribution" allows older employees to accelerate their savings as they near retirement.
