Frequently Asked Questions

How much should I contribute to my 401k?

At minimum, contribute enough to get the full employer match — that is free money. Financial advisors recommend saving 10-15% of income for retirement. The 2026 contribution limit is $23,500 ($31,000 if over 50).

How does employer matching work?

A common match is 50% of your contribution up to 6% of salary. On a $75,000 salary contributing 6% ($4,500), your employer adds $2,250. That is an immediate 50% return on your investment.

How do I convert annual salary to hourly?

Divide annual salary by 2,080 (52 weeks x 40 hours). For example, $65,000 / 2,080 = $31.25 per hour. Adjust the hours if you work more or less than 40 hours per week.

What is the average salary in the US?

The median household income in the US is approximately $75,000 as of 2025. Individual median income is about $45,000. These vary significantly by state, profession, and experience level.
