1. The Components of Cost: Total Cost (TC) is the sum of Fixed Costs (FC) and Variable Costs (VC).
$$TC = FC + VC$$
2. Defining the Break-Even Point (BEP): The Break-Even Point is the level of sales or production at which the
Total Revenue (TR) generated from sales exactly equals the
Total Cost (TC) incurred in production.
$$TR = TC$$
3. Graphical Representation:
• Below the BEP, the Total Cost line is above the Total Revenue line, representing the
Loss zone.
• Above the BEP, the Total Revenue line is above the Total Cost line, representing the
Profit zone.
• At the intersection, the net profit is zero ($TR - TC = 0$).
Therefore, the fundamental identity of the break-even point is that total expenditure matches total income.
