Output  = (Input * Feedback loop resistance ) / Input resistance)

On a clean OP-AMP with a linear response it’s all easy.
If you have some harmonics, or your circuit has some frequencies that
Drop out or resonate then the response will be a little harder to predict.

However that is not a flaw with Feedback, it’s a flaw in the amplifier.
(Or a feature depending on how you look at it.)
