That's not quite right (cf. below).
It seems as if the entire world would like you to believe that this formula is mysterious and difficult to remember but it's actually neither. The bond salesman's method is a truly beautiful formula. Just remember the following: the yield to maturity on a bond is approximately the average amount of interest earned divided by the average amount invested. If you believe and grok that statement then you now understand everything there is to say about the bond salesman's method. How do we get from that interpretation to the above formula? The average amount of interest earned is the total interest earned divided by the number of periods. The (undiscounted) total interest earned is the sum of the coupons plus the difference between the redemption value and the price of the bond; in symbols this is and therefore the average amount of interest earned is . The average amount invested is simply the average of the redemption value and the price of the bond, namely . There ratio of these two is the bond salesman's method, namely .
