To remember any "average" cost formula:
"Average" always means dividing the corresponding "Total" cost by the "Output" (Q):
- \(\text{Average Variable Cost (AVC)} = \frac{\text{Total Variable Cost (TVC)}}{\text{Output}}\).
- \(\text{Average Fixed Cost (AFC)} = \frac{\text{Total Fixed Cost (TFC)}}{\text{Output}}\).
- \(\text{Average Total Cost (ATC)} = \frac{\text{Total Cost (TC)}}{\text{Output}}\).
