Frequently Asked Questions

How much should I contribute to my 401(k)?+
At minimum, contribute enough to get the full employer match — that's free money. The 2026 contribution limit is $23,500 ($31,000 if 50+). Financial advisors generally recommend saving 15% of income for retirement.
What is employer match?+
Many employers match a percentage of your 401(k) contributions. A common match is 50% of contributions up to 6% of salary. On a $75K salary, that's $2,250/year in free money.
What return rate should I use?+
The S&P 500 has averaged ~10% annually, or ~7% after inflation. Use 7% for a realistic inflation-adjusted estimate, or 10% for nominal returns. Be conservative for planning purposes.
