Costs that stay the same regardless of how many units you sell — rent, salaries, insurance, software subscriptions, loan repayments.
Costs that increase with every unit sold — raw materials, packaging, shipping, payment processing fees, sales commissions.
Selling price minus variable cost per unit. This is how much each sale contributes toward covering your fixed costs.
Fixed Costs ÷ Contribution per Unit = Break-Even Units. Sell more than this and you're profitable. Sell fewer and you're making a loss.
