Break-Even point calculator

Break-even is where contribution margin covers fixed costs exactly: each orders earns price minus variable cost, and the fixed costs divided by that margin is the point. What this does not model: volume discounts or tiered pricing, step-fixed costs that jump when you add staff or capacity, inventory and timing, taxes, and the difference between cash and accrual periods. A linear price and a linear variable cost per unit are the whole story here.
