Hi everyone , I am working on ZCD project and I wonder how can calculate the output voltage for this circuit?

Thank you.

Not sure that this post is in the best section.
All the voltages seem to be illustrated & measured. Which voltage do you want to work out?

Your op-amp has no negative feedback so has a huge gain, resulting in the output being driven hard against the supply rails, i.e between nearly +5V and nearly -5V.
