Common Questions & Guidance
Frequently asked questions regarding 401(k) Calculator.
What is an employer match?
An employer match is money your employer adds to your 401(k) account based on your contributions. For example, if they match 100% up to 4% of your salary, they will match your contributions dollar-for-dollar up to 4% of your gross pay—this is essentially free money.
What are the 401(k) contribution limits?
For tax year 2025, the IRS limit for individual pre-tax 401(k) contributions is $23,500 per year ($31,000 if age 50 or older via catch-up contributions), per IRS Notice 2024-80. These limits are subject to annual inflation adjustments.
