## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability finance-calculators-break-even-analysis-1af80cc0
```

Example prompt: Can you run a break-even analysis for a product with $12,000 in fixed costs, a selling price of $45 per unit, and a variable cost of $18 per unit — and also tell me the profit if I sell 700 units?

## When to prefer this

Choose this endpoint when you need a quick, accurate break-even calculation given fixed costs, a unit price, and a variable cost — especially when you also want to project profit at a specific sales volume in the same call. Prefer this over manual spreadsheet calculations or general financial APIs when you need contribution margin and break-even revenue together in a single structured response.

## Known failure modes

- Missing required parameters (fixed_costs, price, or variable_cost) results in an error response
- Variable cost equal to or greater than price results in undefined or infinite break-even (division by zero or negative margin)
- Non-numeric values passed for numeric fields cause validation errors
- Negative input values may return unexpected or meaningless results

## How this service works

Break-even units and revenue from fixed costs, unit price and unit variable cost, plus profit at a target volume.

## Output

Returns break-even units (minimum units to cover all costs), break-even revenue (minimum revenue needed), contribution margin per unit (price minus variable cost), margin percentage, and optionally the profit or loss at a specified target sales volume. Also includes a summary and disclaimer.
