What is the maximum I can contribute to my 401k if I am 55 years old?

For age 55, your maximum contribution includes the base limit plus the catch-up amount, totaling $31,000 for 2024.

If I contribute $5,000 and my tax rate is 22%, how much do I save in taxes?

Your estimated immediate tax savings from this contribution is $1,100.

Project my 401k growth if I have $10,000 now, add $5,000 yearly, at 7% interest for 20 years.

In 20 years, your estimated account balance will be approximately $231,450, with total contributions of $100,000 and interest earned of $131,450.

Use the `max_contribution_tool` by providing your current age. The tool will return the base limit and indicate if you are eligible for catch-up contributions.

The deck got rejected in 8 minutes. This tool forces problem validation with evidence, sourced market sizing, defined unit economics, retention-based traction, and a specific fundraising ask.
