I'm assuming you mean joules/sec or watts and we are talking on an average.
If you have 1000watts in (real actual power) and no losses, then you will
have 1000 watts out (averaged over a complete system cycle so we don't
concern ourselves with peak power).
If you are really meaning joules (energy which assumes power input over a
specified period of time) then the same can be said. 1000 joules in, no
losses and no energy remaining in storage after the period of time, then the
energy out would be 1000 joules.
