I already uploaded the file under name Pefficiency_analysis.asc.
Methode how to calculate efficiency is missing.
Please notice that R1 is not connected to gnd. I suppose you calculated like this: voltage should be: V(n003)-V(n004). Current is I(R1) so power is (V(n003)-V(n004))*I(R1)
Divide Output power by input power?...
Your uploaded simulation works for me.
