Revenue = price × sales. Cash contribution = revenue − (per-sale cash cost × sales) − fixed cash costs. Contribution per hour = cash contribution ÷ total work hours. Break-even sales = fixed cash costs ÷ (price − per-sale cost), rounded up to a whole sale.
Break-even assumes constant price and costs. With a positive fixed cost and no positive contribution per sale, extra sales cannot cover that fixed cost. When fixed cost is zero, zero sales produce zero cash contribution; selling at a loss still makes the scenario worse.
