This document discusses cost volume profit (CVP) analysis, which is a planning study used under marginal costing. It describes two types of CVP analysis: breakeven analysis, which determines the sales volume where there is no profit or loss, and profit volume analysis. The document provides formulas to calculate the breakeven point in terms of volume and value, sales volume needed to earn a target profit, sales value needed to earn a target profit, and margin of safety. It also describes the relationships between variable costs and contribution, and between breakeven point and margin of safety. The lecture was given by Prof. Hafiz Zafar Ahmad at Hailey College of Commerce.
