How this service works
Break-even point for a product: the units and revenue at which total revenue covers fixed plus variable costs. Also returns contribution margin and margin ratio.
Output
Returns the break-even point expressed as number of units and total revenue required, along with the contribution margin per unit and the contribution margin ratio as a decimal or percentage.
Example use cases
Example prompt
“What's the break-even point for my product if my fixed costs are $50,000, I sell each unit for $25, and my variable cost per unit is $10? Give me the break-even units, revenue, and contribution margin.”
Technical details
Endpoint
POSThttps://agent402.tools/api/break-evenWhen to prefer
Use this endpoint when you need a quick, accurate break-even computation without building the formula yourself — especially when you already have fixed cost, selling price, and variable cost per unit ready. Prefer it over spreadsheet logic or manual calculation when the result needs to be embedded programmatically in a financial workflow or agent response.
Side effects
- pricePerUnit equals variableCostPerUnit causing division by zero (zero contribution margin)
- pricePerUnit less than variableCostPerUnit resulting in negative contribution margin and nonsensical break-even
- missing required fields (fixedCost, pricePerUnit, variableCostPerUnit) returning a 400 or validation error
- non-numeric values passed for cost fields returning a schema validation error
- payment failure via x402 protocol returning 402 Payment Required
