Oh boy now there's a question!!!

My answer is that there is no simple calculaltion

Note:

In calculating power at 60 Hz it is easy since we are dealing with a sine
wave. At RF frequencies the wave is complex and not readily amenable to
calculation

Line losses get in the way especially if antenna is not perfectly resonating

Antenna resonance affects the radiated power

Antenna gain gets in the way

With a perfect transmission line and 1:1 antenna gain I vaguely recall
someone telling me the effective radiated power for a 100 watt SSB
tranxmission was in the range of 20 wattas but my memory may be defective

I am sure others are more knowledgable than I
