I still do the same thing from time to time. If you're standing in front

Do it once & program your calculator if need be <sigh>.

Who makes a good programmable calculator?

This looks much like the first one I used for such:
http://www.rskey.org/forsale/detail.asp?id=37
IIRC 17 logical steps were needed & the calculator does 16 ....
(calculate any fillet between any two lines given the radius
one point on each line & each line's angle to the X axis & theTNR)
with line end points & arc center output.
Oops .. output the data for tool centerline (offset from surface)
data for G-code too.
Always had to do that final calculation later.. get one with at
least 18 steps programmable <G>. Modern times, you know.

Whoops .. this says it has "Program memory: 32 program steps"
so this must be a later calculator ormy memory of he number of needed
steps was off. It the later, go for more steps <g>.
