# Government bonds - the most simple example

I would like to have an example of a common case of buying government bonds. (Wikipedia: it is issued generally with a promise to pay periodic interest payments and to repay the face value on the maturity date).

What is the maturity date (years I guess), how much is that period of "periodic interest payments", how much is that interest, and what is the "face value"?

A simple example of the most common case. Or at least a known case of such a transaction. Say for example one of the latest government bonds issuing of Germany or Spain.

Say for example I buy German government bonds at a maturity date of N years, with a periodic interest of M months, and with the interest at P percent each month. Replace N, M, and P with a known case. In case I spend 100,000 Euros for such bonds, how much do I get back? (periodically, in the end and in total)

I think such example would make it easier for the common people like me to understand how government bonds work.

Using an example from the US treasury's website you can buy a \$100 dollar face value bond that pays 3% annual interest semiannually for thirty years. That means you would get$100 \cdot 3\% / 2 = 1.5$dollars every six months, and at the end of the thirty years you also get \$100. In total you would get $1.5 \cdot 2 \cdot 30 + 100 = 190$ dollars but as it is explained in the link in Jamzy's comment adding up dollars in this case is not very sensible, because dollars in different years have different value.
