CVP (Cost–Volume–Profit) analysis studies how costs and volume affect profit. It helps managers answer:
Break-even analysis is a core part of CVP.
CVP analysis is the analysis of the relationship among:
It is used for short-run planning, budgeting and decision-making.
Common assumptions:
Exam tip: write 3–5 assumptions.
Fixed cost (FC): remains constant in total (rent, salary).
Variable cost (VC): changes with output (materials).
Sales (S): selling price × quantity.
Contribution (C): Sales − Variable cost. Contribution first covers fixed cost; remaining is profit.
P/V ratio (Profit/Volume ratio): contribution margin ratio.
High P/V ratio means more contribution per rupee of sales.
Break-even point is the level of sales where:
At BEP, the firm neither makes profit nor loss.
Let:
Then:
Margin of Safety shows how much sales can fall before reaching BEP.
Higher MOS indicates lower risk.
Target profit planning:
These formulas help decide sales targets and budgets.
Operating leverage measures how sensitive operating profit is to changes in sales.
High operating leverage means small change in sales causes large change in profit (because fixed costs are high).
These charts are used in presentations and planning.
So BEP is a guide, not an exact prediction.
FC=₹50,000; SP=₹100; VC=₹60 → C=₹40
Actual sales = 2,000 units; BEP = 1,250 units
Target profit=₹20,000
Quick formula table:
Simple flow:
Given FC, SP, VC

Find contribution (SP−VC)
↓
Compute BEP = FC / contribution
↓
Compare actual sales with BEP → Profit/Loss and MOS

CVP (Cost–Volume–Profit) analysis studies how costs and sales volume affect profit. It is used for short-run planning.
Uses (any three):
A manager uses CVP to reduce uncertainty and set realistic sales targets.
Contribution (C) is the amount left after covering variable cost and is used to cover fixed cost and profit.
Formulas:
Higher P/V ratio means higher contribution per rupee of sales.
Break-even analysis is a technique to find the sales/output level where a firm has no profit no loss (i.e., TR = TC). It is part of CVP analysis.
Let SP = selling price per unit, VC = variable cost per unit.
Thus, BEP is a useful planning tool but should be used with realistic assumptions.
