Introduction to U.S. Economy: Personal Saving


Personal saving, which includes the saving of households
but not of businesses or government, can have a significant
impact at both the individual and economy-wide levels in
the long and short terms.

Economic Considerations
The saving rate, which is the ratio of total personal savings
to disposable income, presents a tradeoff between current
and future consumption. A relatively low saving rate
implies higher current consumption but lower future
consumption. Greater present consumption supplies
individuals now; however, it leaves little to be invested in
capital projects that will boost future living standards.
Conversely, a relatively high saving rate implies lower
current consumption but higher future consumption. This
tradeoff has implications for both short-term and long-term
economic growth.

Short-Term Economic Impacts
In the short term, a rising personal saving rate can be a
temporary impediment to economic activity, assuming no
other changes to income. If on average individuals begin
saving a larger portion of their paychecks, it means less
money  is being spent on consumer goods and services in
the economy. Because consumer spending makes up about
70%  of the U.S. economy, even a small decrease in
consumer spending can reduce aggregate demand and
economic activity. Alternatively, a falling saving rate may
result in temporarily faster economic growth as individuals
spend a larger portion of their pay on goods and services.

A rise in the saving rate during an economic downturn can
be problematic. In response to a recession, individuals may
rationally respond to increased uncertainty about their
future income by increasing their saving rate to protect
them from potential job loss or reduced income in the near
future. As a result, however, the economic downturn is
further exacerbated due to the additional decrease in
consumer spending resulting from the rising saving rate. By
contrast, in the midst of a healthy and expanding economy,
a rising saving rate may result in a more sustainable level of
consumer spending, thus preventing the economy from
overheating. An overheating economy occurs when demand
for goods and services exceeds the economy's ability to
produce those goods and services, which is often
characterized by accelerating inflation followed by a
recession.

Long-Term Economic Impacts
In the long term, however, a higher saving rate will
generally lead to higher levels of economic output, up to a
point. When individuals save a portion of their income,
those saved funds are generally loaned out to businesses to
finance new investments. For example, an individual's


401(k) is a saving vehicle for their future consumption after
retirement, but before retirement, those funds are generally
invested in various companies through the purchase of
stocks and bonds.

The overall level of investment is one of the main
determinants of long-term economic growth. Business
investments in physical capital (i.e., machinery, buildings,
and factories) allow the economy to produce more goods
and services with the same amount of labor or raw
materials, increasing the productive capacity of the
economy. As  such, all else equal, a higher saving rate will
result in a higher level of physical capital over time,
allowing the economy to produce more goods and services.

How is Personal Saving Measured?
Economists generally track economy-wide saving via the
personal saving rate (see Figure 1).

the United States. Grey bars represent recessions.

Since the early 1970s, the U.S. personal saving rate has
fallen from above 12% to a low of 1.9% in 2005. Following
the beginning of the 2007-2009 recession, the saving rate
briefly increased before beginning to fall again. Over the
past year, the saving rate has averaged about 6.7%,
suggesting that for every $100 of disposable income
individuals are spending about $93.30 and only saving
about $6.70.

The personal saving rate produced by the Bureau of
Economic  Analysis (BEA) is measured as the difference
between aggregate income and consumption spending,
