Total cost is variable plus fixed costs. Cost ratio is total cost divided by revenue.
Bars are scaled to the larger of total cost and profit. When costs exceed revenue, the profit bar is shown in amber and the verdict flags the loss.

Costs are held at the values above; only revenue changes across rows.
Net profit = revenue − variable costs − fixed costs. Net margin = net profit ÷ revenue × 100%. Total cost = variable costs + fixed costs. Cost ratio = total cost ÷ revenue × 100%.
Revenue $100,000, variable costs $68,000, fixed costs $8,000: total cost = $76,000, net profit = $100,000 − $76,000 = $24,000, net margin = $24,000 ÷ $100,000 × 100% = 24.00%, and cost ratio = 76.00%.
This is an operating view: interest, taxes, depreciation, and one-off items are not separated out. If your cost figures already include them, the margin reflects that; if not, it does not. Costs are treated as fixed totals for the period, not per-unit rates.
Net profit = revenue − variable costs − fixed costs; net margin = net profit ÷ revenue. It splits a period's revenue into what costs consumed and what remained.
Variable costs move with output — materials, per-order fees. Fixed costs do not — rent, base salaries. The split matters for break-even analysis; for net profit only the total matters.
Costs exceeded revenue for the period: a loss of that amount. The margin is negative by the same proportion.
No. Gross margin stops at cost of goods sold; net margin counts all variable and fixed costs entered here, so it is usually lower.
No, unless tax is already inside the cost figures you enter. Apply tax treatment separately to the net profit.
Margin divides by revenue, so at zero revenue it is undefined. Profit itself is still shown as negative total costs.
