Quick guide

How to use this calculator

  1. Enter values from one real situation and keep currencies, quantities, and periods consistent.
  2. Use the optional fields only when they apply; the calculator will keep every entered adjustment visible in the result.
  3. Compare the component outputs and read the calculator-specific boundary before making a purchase or plan.

Calculation method

Calculation method

Person share = total × person weight ÷ total active weights, with displayed minor-unit remainders allocated deterministically.

Entered fixed decimals use exact rational arithmetic wherever the task involves money, ratios, or allocations. Whole packages, tables, seats, and items round only where the real task requires indivisible units.

Worked example

Worked example

Person share = total × person weight ÷ total active weights, with displayed minor-unit remainders allocated deterministically.

Supported inputs

Precision and limits

Your scenario

No live price, promotion, retailer policy, tax, cultural norm, household consumption rate, attendance rate, or media speed is supplied automatically.

Plan, not a guarantee

Results organize visitor-entered assumptions. They do not guarantee availability, attendance, product life, savings, suitability, or contractual rights.

Precision and privacy

Inputs stay in this browser. Invalid denominators, contradictory counts, impossible percentages, and unsupported ranges return explicit messages rather than misleading results.

Calculator-specific boundary

Weights must be agreed by participants; the calculator does not determine fairness. Avoid entering sensitive names or account details.
