Financial Calculators

Below are links to online financial calculators.

These tools are presented by various companies seeking to make a profit, however the companies seem to be reputable.

Here is one of the many "Compound Interest Calculators" use this tool to identify how an investment (or debt/loan) will grow over time. This one does the same thing with fewer variables.

If you want to understand how much an amount of money you have today will be worth in the future use this "Present Value Calculator"

Principal    Interest    Credit    Debt

Principal; Interest; Credit; and Debt are related words. In order to study these words you should recognize and understand some conventions used by many people when dealing with finances. Negative numbers, we’ll refer to these as “debt” (unless you are an accounting person) are often written like this: ($1,000); you are most likely used to thinking of this as -10,000. (Also, negative numbers are often displayed in the color red. Positive numbers in these cases are usually black.)

Principal is an amount of money that one starts with. Sometimes it is a debt as when it is an amount borrowed.
Three common reasons to borrow money:

Sometimes it is a positive number as when it is invested.
The most common ways people invest money are: savings accounts, U.S. savings bonds, certificates of deposit, money market instruments and funds, index funds, mutual funds and exchange traded funds, bonds, and stocks. Typical interest rates earned on these range (over the long term) from near 0% to 7%. Sometimes these investments lose money.

Interest is a percent increase in an investment or (debt). Interest usually “compounds” which means that it increase and also increases based on it’s previous increase. (Interest that only increases on the original principal is called “simple interest”).

The power of “compounding interest” is significant. Complete the tables below in order to understand the power of compounding.

HOMEWORK listed at bottom of this post!

Remember that Government books must be returned by the time we check out Econ texts next class.

Vocabulary Flash Cards are due NEXT class.

Today class viewed three short lectures from the Khan Academy

1) Review of the Prisoners' Dilemma

2) In depth explanation of Nash Equilibrium

3) Why parties to cartels cheat

Then students worked in pairs to complete two more applications of the prisoners' dilemma and pay off matrices to business situations.



Next the class was given some tools for analyzing one's attitudes and values towards money and wealth.





Students were asked to answer the following questions for next class:
1) Did the sum of your answers surprise you?
2) What do you notice about yourself? What if anything do you the results make you think about or wonder?

Monday, February 1st

Class began with a discussion and explanation of tonight's Iowa Caucuses. We reviewed these to stories from The Guardian "live coverage" and "How the Iowa Caucuses Work"

Next the class returned to regularly scheduled Economics work.

Students were reminded that we will check Economics texts from the library on Friday; it is graded assignment to return Government texts (as well as a graduation requirement). Students were reminded that vocabulary flash cards are due on Friday, as well.

Class reviewed the "Prisoners' Dilemma" from last class, and Mr. Zartler gave an example of how it relates to business decisions.

Small groups then were given a chance to apply their knowledge of game theory to another example from business, and to an awkward high school drama-social situation.
