Guide

What is the break-even point?

Your break-even point is the sales level where total revenue equals total cost — no profit, no loss. Every sale beyond it adds profit.

Formula

  • Contribution per unit = Selling price − Variable cost per unit
  • Break-even units = Fixed costs ÷ Contribution per unit
  • Break-even sales = Fixed costs ÷ Contribution margin %
  • Units for target profit = (Fixed costs + Target profit) ÷ Contribution per unit

Fixed vs variable costs

Fixed costs stay the same whatever you sell: shop rent, salaries, electricity minimum, internet, software, loan EMI. Variable costs rise with each sale: product cost, packaging, delivery, payment fees, sales commission.

For shops with many products

Use your average selling price per bill and average gross margin. If your average bill is ৳800 with a 25% margin, contribution per bill is ৳200.

FAQ

Frequently asked questions

What if my contribution margin is negative?
Then you lose money on every sale and can never break even. Raise the price or cut the variable cost first.
What is margin of safety?
How far your expected sales are above break-even. A 30% margin of safety means sales can fall 30% before you start losing money.
Should I include my own salary?
Yes. Include a fair salary for yourself as a fixed cost, otherwise you will "break even" while working for free.
