Personal Investments • Re: Understanding the math behind a 20 year treasury

Ok I wasn't taking into account that I can actually buy more than 250 bonds with 250k. I'm still confused how 250k at 5.03 yield can return 263k that seems like a 5.2 % yield based on 250k at 20 years. Is it just that I will be returned 1k per bond at 263 bonds? The annual coupon is based on the number of bonds or the amount invested?
Besides the nice explanation that was just given, remember that the coupon is a fixed amount. You get 5.03% of every $1000 of face value, or $50.03, every year. This has no relationship to what you paid.

Now, if you paid $950 for the bond, then that $50.03 is obviously more than 5.03% of $950, so you're effectively getting 5.2% on your investment.
Hmmm, I don't think that is right. The coupon here is fixed at 4.265%, so you get 4.265% of every $1,000 of face value.

Now if you paid $950 for the bond, you will effectively get 5.03% which is 4.265%/year + the $50 at maturity ($1,000 returned for your $950 spent).

Nobody is getting 5.2% on this 20 year bond. Don't be mad at me for delivering the bad news :wink: :sharebeer
