How early and much you save is far more important than your investment returns.

​Consider this example:

Attorney A: begins saving at age 25 and, on average, saves $20,000 a year into an investment account earning 5% annually until age 55.

Attorney B: begins saving at age 30 and, on average, saves $10,000 a year into an investment account earning 10% annually until age 55.

Which attorney has the higher account balance at age 55?

You may have guessed correctly that Attorney A does. 

In fact, their account balance is about $345,000 more even though they earned half the rate of return.
Bottom line – focus on your savings rate more than account performance!
