Some people save for real, and some just nominally.
People who save for real are mindful of inflation. You think your money is safe in your bank account? It’s earning interest, you tell yourself. Sure it is, but how much interest, exactly? And what’s inflation at? You need these things to calculate your real savings.
Inflation measures how much prices are going up. If inflation rose at 2% (which it has been annually on average for awhile now), then that means prices are up 2%. It also means your salary (which hasn’t changed in the past year) is giving you less buying-power than before. The prices of everything around you are going up, and yet your paycheck is staying the same. So you can buy...less.
The same applies to your savings account. If your savings account is only giving you 1% interest per year (APY) and inflation is rising at 2% per year, then your real savings are going down by 1% each year. Your money is eroding away...and you don’t even know it. Well, now you do. The average APY on savings accounts in 0.09% according to the FDIC, so...yeah. Everyone’s money is eroding away if it’s not keeping up with inflation.
Think about it this way: Grandma Ethel kept $100 in her savings account with 1% interest starting in 1959, and never added or took out any money. Between 1959 and 2019, that $100 dollars grew to $181.67
Back in 1959, $100 could buy you 200 movie tickets. Grandma Ethel could’ve watched 200 movies with that money. Today, her $181.67 could now only buy her 20 movie tickets. Movie ticket prices went up from an average of 50 cents to just over $9. Even though her savings were earning interest, prices were rising much faster.
In macroeconomics, real savings matters, too. Keynes’ famous IS-LM model, where S is savings, can be done in real (rather than nominal) terms to compare results across time.
Now go check your bank account APY, and find one that’s at least 2%. Oh, and one for Grandma Ethel, too.

Finance: What are Gross Domestic Product...8 Views
Finance Allah Shmoop What are gross domestic product GDP and
gross national product GNP So how do you know how
great your country is Well you can measure how many
missiles you have or you can count the number of
Olympic gold medals You've one or you can count the
number of Starbucks locations you have all over your country
for you can measure the strength of your economy Well
how do you do that Economists used to main measures
One is called gross domestic product called gross national product
Gross domestic product might sound like what happens when you
flush a baby alligator down the toilet And three years
later it crawls back out looking for its mommy But
in actuality it represents the total value of all the
stuff you make in your country along with all the
services you provide You know like legal services and dental
cleaning services and stuff like that And you know that's
provided by your citizens There You live on the sovereign
island nation of squish squad Scary Located just offshore of
Norway you are one of twelve inhabitants and all of
you fish for herring all day Each of you catch
an average of ten pounds of herring every day Hearing
sells for about ten bucks a pound and everyone works
two hundred days a year so multiply that all up
and you get twelve People work in two hundred days
a year each each catching ten pounds each day with
each pound selling for ten bucks And well you could
say the GDP of squish squad Scary is two hundred
forty thousand dollars That's the value of all the stuff
you're country made in a year Meanwhile elsewhere in the
world the numbers get a bit higher For instance the
GDP of the U S was about nineteen trillion dollars
in two thousand seventeen so Well yeah that's a little
bit more But of course the U S has three
hundred twenty five million ish people in it instead of
the twelve squid squid aeons And its GDP includes things
like airplane manufacturing and high value financial transactions And you
know shmoop subscription sales instead of just herring fishing So
it makes sense that the U S economy would be
much much bigger toe Look at how an economy is
doing People usually watch how it changes over time say
one of your fellow squish Quaid Ian's starts fishing with
dynamite Well it's a new technique Output goes from ten
point today to twelve next year With the new output
your GDP goes two hundred eighty eight thousand from the
two forty and change before That's twenty percent GDP growth
in a year We'll guess what big complex economies like
the US pretty much never see growth rates like that
Economists usually consider it a healthy growth rate to be
more like two or three percent in a given year
Smaller countries and developing countries can have bigger growth rates
Right Like take China It's a big country biggest population
in the world with no more than a billion and
a half people But it's still racks up relatively high
GDP growth rates because of the rapid expansion of its
manufacturing base Right they optimize their farmers and take them
from growing turn ups and instead have them assemble semiconductors
and stuff like that way higher margin to sell a
semiconductor than a turnip As recently as two thousand ten
China put up annual GDP growth rates still in the
double digits like ten percent and hit double digits and
change for five consecutive years in the early two thousand
Well GDP doesn't always go up in nations around the
world The year after discovering dynamite fishing swish squad Ian's
suffered a Siri's of significant storms The number of work
days went down from two hundred to one ninety Everything
else stayed the same self In that year GDP fell
to two hundred seventy three thousand and change from the
two eighty eight It was the year before decline of
five percent Well he kind of is called that decline
a contraction if a contraction happens for two or more
quarters in a row so like two three months periods
in a row the country is considered to be in
a recession If the contractions air deep enough and last
long enough well then that's called the depression like it
goes on for a year Two years or three years
Both GDP and GNP measure the economic output of a
country but they used different definitions about what all that
entails Gross domestic product consists of all the products and
services made it given your inside the country So you
know made within the borders of the country made domestically
gross national product measures the stuff made by people or
companies from a country regardless of where it was actually
made like you're an American citizen No building pots or
pottery in Mexico We found that in the GNP number
so GDP tracks where it was made GNP tracks Who
made it So if an American it's a toilet cozy
while sitting in his living room in Des Moines that
gets included in both GDP and GNP However if an
American goes on vacation Teo Cameroon and it's a toilet
cozy in his hotel room there well that's included in
GNP but not in GDP was made by an American
but not in America Well meanwhile if the American comes
back home to Des Moines and a Scottish friend of
his comes over and it's a toilet cozy for him
that would count in GDP but not in GNP right
The toilet cozy was made in the US but not
by an American In the old days like before the
nineteen nineties GNP was typically used to track national economic
growth However with the dramatic rise of globalization around that
time GDP became much easier to track Eventually it became
the go to measure of growth to review Both GMP
and GDP track national economic output They both look at
the amount of goods and services produced by the country
though they have different working definitions about what that means
The size of GDP and GNP are impacted by the
size of a country In the level of economic and
technical sophistication Big complex economies like the US usually aspire
to modest growth like two or three percent smaller Countries
in developing economies can post much higher growth rates with
percentages in the double digits Not being all that uncommon
GDP measures the value of stuff produced within a country
regardless of who makes it GNP measures the value of
stuff made by citizens of a country regardless of where
it's made So if a squish squatty and citizen were
toe float a raft into Norwegian waters and catch some
herring there While that would count on GNP on their
books but not G Meanwhile if he invited a Norwegian
friend over for a day of fishing for anything that
Norwegian caught would count on the squish Wadi and GDP
but not on the squish Claudia and G N P
if the scratch Wadi Ins were to launch a surprise
attack on Norway However wealth and all bets would be 00:06:23.518 --> [endTime] off You just have to see who is
