This is the total value of your account at the end of 2 years. It is particularly interesting to note the massive difference between the taxed and non-taxed numbers after 20 or 30 years. The inflation column shows you the effect of inflation on your initial deposit. If your investments do not at least exceed the rate of inflation, you are losing money. If you look at the account value and it is less than the value in the inflation column over time, then your investment is actually losing money.
Taxes often have that effect on lower-performing investments like savings accounts and CDs.
