Does 401k grow faster with more money?

The growth of your 401(k) largely depends on the amount of money you contribute to your account each year as an employee and the matching contributions that your employer adds to your account over time. The more money you and your employer contribute to your 401(k), the more potential it has to grow.

How fast does 401k grow?
