Frequently Asked Questions

What is a 401k calculator?

A 401k calculator is a tool that estimates how much your 401k retirement savings will grow over time based on your contributions, employer match, and expected rate of return.

How is employer match calculated?

Employer match is typically calculated as a percentage of your salary, up to a certain cap. For example, a 50% match up to 6% means if you earn $60,000 and contribute 6% ($3,600), your employer will add $1,800 (50% of $3,600).

What is a good 401k contribution rate?

Financial experts recommend contributing 10-15% of your income to retirement savings. However, you should at least contribute enough to get your employer's full match.

What is a realistic expected return?

Historically, the stock market has returned about 7% annually after inflation. You can adjust the expected return based on your investment allocation - more aggressive portfolios may return more, while conservative portfolios may return less.

Should I contribute to Roth or Traditional 401k?

The choice depends on your current tax situation. If you expect to be in a higher tax bracket in retirement, a Roth 401k may be better. If you're in a high tax bracket now, Traditional 401k contributions may save you more.
