Last
month's article, "Why are Administrative Expenses
Important?", covered the impact of fees on your investment
returns. Lower fees mean you get to keep more of your own
money. If you are investing in the TSP, you probably
already know that you are paying less for your investments than
just about any other investor.
But
administrative fees aren't the only thing that can chip away at
your investment returns. You must also take into account
the effects of inflation as well as the certainty of income taxes.
Inflation
Inflation
is the increase in the cost of living. As prices of goods
and services rise over time, your dollar buys less. A
common measure of inflation is the Consumer Price Index (CPI).
You
should be concerned with inflation because it erodes the value of
the money you are saving for your future goals. Your TSP
account is especially at risk because you will be relying on it
to provide income throughout your retirement years.
At
an average annual inflation rate of 3.2%, a $150 trip to the
grocery store today will cost:
$205.74
in 10 years
$282.18
in 20 years
$387.03
in 30 years
Inflation
is devastating because you could end up with less purchasing
power in the future than you have today. In the above
example, your purchasing power over a 30-year period is reduced
by more than 50%. This presents an enormous risk to your
retirement portfolio. In investment terms, it's called
inflation risk.
A
well-diversified portfolio is one of the best ways to offset
inflation risk. Keep in mind that as you decide how to
distribute the money in your account among the TSP funds, you
should consider your time horizon and your tolerance for
risk.

the Money in My TSP Account?" in the July 2009 issue of this
newsletter.
Income
Taxes
All
of your contributions to your TSP account have been before tax
(or, in some cases, tax-exempt) and tax on the earnings growth
has been deferred. This is the greatest advantage of
tax-deferred plans like the TSP because over time, you accumulate
earnings on:
- Your
contributions;
- Your earnings; and
- The amounts you would have
otherwise paid in taxes.
But
eventually, the IRS is going to want its share. Once you
begin taking withdrawals from your TSP account, you will have to
pay taxes at your ordinary income tax rate. However, you
will pay tax on the earnings portion only of any tax-exempt
contributions (made while serving in a combat zone) that you
withdraw.
Depending
on your income bracket and the prevailing rates at the time, the
taxes you pay on your TSP withdrawals could be anywhere from
negligible to significant. Of course, it is impossible to
know what tax rates will be or how tax laws might change in the
future, particularly if the future is a decade or more from
now. But knowing that tax will come due when you begin
withdrawing your TSP account can help you better determine how
much you should save and how to allocate those savings among your
investment options.
What
matters most about investing for retirement is the money that you
actually get to keep. Inflation and income taxes, in
addition to administrative fees, affect your retirement savings by
either reducing the amount of your income or its purchasing
power.
