This is a simple calculator that I made. It doesn’t take the place of the straddle vs condor calculator on the site but has a couple of variations that some may find useful.
I think the most helpful feature may be the ability to vary the take profit levels on a straddle. If you would like to take profit at 75% or 50% of risk instead of going for a 1:1 this will help with the math.
You can also vary your stop loss on an iron condor and see what your overall p/l might be.
Fields in gold will be manual entry.
Hope it helps and let me know of any errors found.
