Fixed Sales Bundle Break-even Planner

How to use Fixed Sales Bundle Break-even Planner

Keep each product’s positive integer bundle quantity fixed. Sum its price-minus-variable-cost contribution, divide fixed cost plus target profit by bundle contribution, and round up to a whole bundle with an exact profit witness.

1. Enter model json (schema and units below).
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• Plain decimal JSON numbers or strings, at most six fractional places, magnitude at most 1,000,000,000; raw numeric spellings and duplicate object members are checked. Exact rational arithmetic is capped at 8,192 bits. Text is at most 30,000 characters; a local JSON download preserves exact fractions or full stored approximate numbers. 1–50 products; bundle quantities 1–1,000,000; nonnegative prices, costs and targets. Individual losses are allowed only if the total bundle contributes positively. Mix, prices and costs are fixed assumptions; no demand or capacity guarantee.
• Local calculation only; no input persistence or external lookup. Text/JSON is limited to 30000 characters and output to 1000000 characters. Numeric model inputs and precision/work limits are stated on this page. Approximate JSON numbers retain full stored values; exact arithmetic outputs retain decimal or fraction strings. Unsupported states fail explicitly.
• Educational user-assumption arithmetic only. No live prices, laws, tax rules, quotes or financial advice.
