Want to teach your students (or yourself) how much a summer job income can add up to over the years? Using a Math Common Core State Standards example for linear equations or functions, this excel document already has all the dates and formulas set in a data sheet. All the charts and results are in another sheet. This shows the students the short and long version of the savings effect.
Compound interest and financial literacy are hard topics to marry. This example of savings growth is much more appealing that learning about student loans or credit cards.
To make this document flexible, just change the one field on the 3rd sheet to make it all update.
P.S. It might be fun for you to see how much you need to save for your retirement.
