How much do you add to the desired length of your wood shafts to make up for what goes in the point and nock?

I believe you add 1 inch....

That's what I do. I taper the nock and then cut the arrow about an inch longer than BOP. Close enough for me...

Yup what they said!!  

I just cut the nock taper and glue on the nock.  I have a set of lines on my work bench that I use to mark the desired legnth from there.  To make the marks I found an arrow at the length I wanted and took off the point and used a sharpie to mark the end of the nock and the cut line on the end.  When I put the taper on the point end all the arrows are the same length.

1" for front point.

I add 3/4 of an inch for all my points -- field, broadhead or judo.

I always check the grain on each end of the shaft and cut my arrows to length before I taper them, using the best part of the 31 1/2 or 32-inch shaft.  Most times, this involves cutting the extra length from one end only, but sometimes, I take a little off of each end.  I allow 1 inch extra for clearance from the riser and 3/4 to 1-inch for the point taper -- 3/4 inches for field points, 1 inch for broadheads.  For example, I draw 28 inches and cut my shafts to 29 3/4 or 30 inches.

I had a good tip from Ron LaClair. Take a clothes pin and put it on the shaft. Pull back till it hits your hand, and add an inch

I like them 2 to 3 inches longer then my draw of 27". If I break off a point, I still have an arrow I can shoot. As long as they shoot straight, keep them long.
