Good to know

• Sales, average assets and average equity must be positive. Negative income represents a loss; no industry benchmark, valuation or investment recommendation is supplied.
• Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
• Educational user-assumption arithmetic only. No live prices, laws, tax rules, quotes or financial advice.
