Frequently Asked Questions

How is 401(k) growth calculated?

We use monthly compounding: balance × (1 + monthlyRate)^12 for each year, plus annual contributions with employer match.

What is a typical employer match?

Many employers match 50% of the first 6% of salary contributed, effectively giving you 3% free money.

What return rate should I assume?

Historically, a diversified stock portfolio returns 7-10% annually. Consider lower rates (4-6%) for conservative planning.
