How this service works
Break-even sales units - Sequential input-change attribution: Change each input from baseline to final in declared field order, reporting each incremental effect; order dependent. Metric: Break-even sales units. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded sequential input-change attribution report.
Output
A JSON response containing the break-even waterfall attribution: for each input field (in declared schema order), the incremental effect on break-even sales units as it moves from baseline to final value, plus the overall formula used, units, and stated limitations of the analysis.
Example use cases
Pricing change impact on break-even
“My product's unit price is going up from $50 to $60, fixed costs stay at $10,000, and variable cost per unit stays at $25. Can you run a sequential waterfall to show me how much of the break-even unit reduction comes from the price increase alone?”
Cost increase attribution for CFO report
“Our fixed costs rose from $80,000 to $95,000 and variable cost per unit went from $30 to $33, while unit price held at $70. Do a step-by-step break-even waterfall so I can show the CFO exactly how much each cost driver widened our break-even threshold.”
Full scenario comparison for business plan
“I'm modeling two scenarios for my business plan: before — unit price $15, fixed costs $3,000, variable cost $9; after — unit price $18, fixed costs $3,500, variable cost $10. Give me the sequential input-change attribution for break-even sales units so I can see each variable's incremental effect in order.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-break-even-units-waterfall?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to understand not just how break-even sales units changed between two scenarios, but how much each individual input (price, fixed costs, variable cost) contributed to that change in sequence. It is order-dependent, making it ideal for waterfall/bridge chart analysis and CFO-style variance reports. Use alternatives if you need simultaneous (Shapley-style) attribution, a sensitivity table across a range of values, or a simple before/after comparison without step decomposition.
Side effects
- Missing required fields in before or after objects returns a validation error
- unit_price must be greater than 0 (exclusiveMinimum); zero or negative value rejected
- variable_cost_per_unit >= unit_price causes infinite or undefined break-even (contribution margin ≤ 0)
- Values exceeding 1,000,000,000,000 are rejected by schema maximum
- Non-numeric input types return schema validation errors
- Insufficient USDC balance or x402 payment failure blocks request
