Hey MMMers
I'm a math teacher, and on Friday, I'm starting a 6 day project with my STEM Algebra 2 class on FIRE, using what we've learned about exponentials and statistical analysis to create retirement projections.
For day 1, I to do their own analysis and determine the growth rate of Stocks, Bonds, Housing, and Gold, using historical data.
I have data for everything...except BONDS. Can anyone help by giving me a link to a website that shows year vs bond price of some total bond index? I feel like it shouldn't be hard to find, but I can't find it. For example, Vanguard Total Bond...what price was it selling for on January 1 for the past 20 years? Or something like that.
I'll keep looking, but any help would be appreciated.
Here's the Project Daily Plan, for those interested:
Day 1: Compare a few asset Classes....Stocks, Bonds, Housing, Gold.
Day 2: Explore the Trinity Charts and learn how to read them + the Shockingly Simple Math of Early Retirement Chart from MMM
Day 3-5: Pick two careers. Find research their pay. Run the numbers for a 10%, 20%, 30%, 40%, 50% savings rate to see how much you'd have to live on to retire in various numbers of years.
Day 6: Present your data to the class for your two careers/savings rates, and explain what career/savings rate combo you'd pick if you had to choose today.

I wish you were my math teacher in 1982.

Yes, what a chance to teach a group of young people about this concept. Maybe 1 or 2 will remember it when they grow older.
Is is an option to add education cost to the project? Like a career in the trades vs a career as a PhD?

Hi Linda,
Yea, I'm lucky to have the platform to share the information.
Education cost would be a great thing to add in there in the future. It'd be fun to compare a 30-40k job that you can do right out of high school vs a 60k job that you can start after 4 years college vs something like a doctor that pays far more, but you can't really get earning till your almost 30. It'd be fun to figure out where the break even dates are.

that sounds like a great idea.
You can get historical bond data from robert shiller's website:

I have heard podcasts about very well educated people who at the age of 28 start working with an enormous study debt. It takes them 7 years or so before they can start saving money.
