I want to know exactly how to calculate the break-even point for my promotions, considering factors like cost of goods, profit margins, and potential increased sales volume.

TL;DR - Quick Answer

Calculate break-even by dividing fixed costs by contribution margin percentage. Determine the sales volume needed to cover costs at different discount levels, ensuring the increased unit sales offset reduced per-unit revenue.

Comprehensive Break-Even Discount Analysis

Understanding your discount break-even point is crucial for maintaining profitability while driving sales growth. This guide will walk you through precise calculation methods and strategic considerations.

Core Break-Even Formula

Break-Even Formula

Break-Even Volume = Fixed Costs / (Price - Variable Cost)
  • Fixed Costs: Overhead expenses
  • Price: Original selling price
  • Variable Cost: Per-unit production expense

Discount Impact Calculation

New Break-Even = Fixed Costs / (Discounted Price - Variable Cost)
  • Discounted Price: Original price minus discount percentage
  • Increased sales volume required to compensate
