Average 401(k) balances at 50
By the time you hit 50, you should have six times your salary invested for your later years. The BLS reports the average salary for workers ages 45 to 54 is $69,628. This would mean a typical worker should have savings of nearly $418,000.

Finally, by age 60, you should have eight times your final salary, and, by age 67 (full retirement age for many in the U.S.), you should have 10 times your final salary. By this point, workers are getting very close to retirement and should ideally have a substantial nest egg.
How much could your 401(k) grow?
The earlier you start investing in your 401(k), the easier it is to build a hefty balance thanks to compound earnings.
When you invest money, your investments earn money for you. This can be reinvested so you then have a larger pool of assets earning returns. Your money can grow exponentially. That's why Albert Einstein was famously quoted as describing compound interest as the "eighth wonder of the world."
The chart below shows how much $1,000 invested in your 401(k) could turn into by age 67, depending on when you make your $1,000 investment and assuming an 8% average annual rate of return.
