Inventory Usage ABC Review

How to use Inventory Usage ABC Review

Multiply period units by unit cost, sort by exact usage value, and classify from cumulative share before each item. User-entered cutoffs and stable tie order make crossing-item treatment reproducible.

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. 1–500 unique items, nonnegative units/costs, positive total. Cutoffs are fractions satisfying 0 ≤ A < B ≤ 1. This is a declared-value prioritization scenario, not a demand forecast or inventory policy.
• 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.
