How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "production": 1000,
  "material_each": 2.5,
  "opening": 800,
  "ending": 500,
  "price": 4
}

Accuracy and scope

Deterministic planning scenario; inputs are assumptions, not forecasts. Excludes taxes, financing, legal requirements and costs not explicitly entered. Source explains the underlying planning framework; this specific scenario arithmetic is original.
