  "summary": "With $8,000 in fixed monthly costs and a 40% contribution margin, you need $20,000 in monthly sales to break even.",
  "description": "Break-even revenue is the point where your contribution margin (sales minus variable costs) exactly covers your fixed costs, leaving zero profit and zero loss. This calculator divides fixed costs by your contribution margin percentage to find break-even revenue, and also shows break-even in units if you sell a single product at a known price and variable cost.",
  "formula": "Contribution Margin % = (Price − Variable Cost per Unit) ÷ Price. Break-Even Revenue = Fixed Costs ÷ Contribution Margin %. Break-Even Units = Fixed Costs ÷ (Price − Variable Cost per Unit).",

  "faq": [
    {
      "q": "How much do I need to sell to break even?",
      "a": "With $8,000 in fixed monthly costs, a $50 price, and a $30 variable cost per unit (40% contribution margin), you need $20,000 in monthly sales, or 400 units, to break even."
    },
    {
      "q": "What's the difference between fixed and variable costs?",
      "a": "Fixed costs (rent, salaries, insurance) don't change with sales volume, while variable costs (materials, per-unit shipping, sales commissions) rise and fall directly with how much you sell."
    },
    {
      "q": "Why does a higher contribution margin lower break-even revenue?",
      "a": "A higher margin means each dollar of sales contributes more toward covering fixed costs, so you need fewer total sales dollars to cover the same fixed cost base — this is why raising prices or cutting variable costs speeds up reaching break-even."
    },
    {
      "q": "What happens to profit above the break-even point?",
      "a": "Every unit sold beyond break-even contributes its full margin straight to profit, since fixed costs are already fully covered — this is why sales beyond break-even are disproportionately valuable to overall profitability."
