Two net molecules of ATP per fermentation cycle.
The first step of fermentation is glycolysis, which produces a net gain of 2 molecules of ATP. Fermentation produces no additional ATP.

Fermentation does not directly cost ATP; in fact, it produces a small amount of ATP through substrate-level phosphorylation. However, fermentation does not generate as much ATP compared to aerobic respiration.
During lactic acid fermentation, 2 ATP molecules are produced per glucose molecule metabolized. This process does not require oxygen and is commonly used by muscle cells during strenuous exercise to generate energy quickly.

2 ATP's are produced
Cellular respiration is more efficient than fermentation. Cellular respiration produces approximately 36-38 ATP molecules, while fermentation produces only 2 ATP, which is a significant loss in usable energy.
Glycolysis
ATP is released in glycolysis, cellular respiration, and fermentation.
