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

{
  "area": 300,
  "whole_rate": 10,
  "lost_area": 15,
  "small_rate": 14,
  "extra_monthly": 500,
  "conversion": 20000
}

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.
