Quick Revision Takeaways
Common Exam Pitfalls to Avoid
⚠️ Common Error: Dividing TFC by P instead of (P - V) when calculating break-even units.
✓ Correct Approach: Always divide TFC by the contribution margin (P - V).
Why: Revenue from each unit sold must first cover its own variable manufacturing cost before contributing to fixed overheads.
