20000 currency
Roof years
10 years
Roof fund
5000 currency
System cost
12000 currency
System years
6 years
System fund
3000 currency

Expected results

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

{
  "roof_cost": 20000,
  "roof_years": 10,
  "roof_fund": 5000,
  "system_cost": 12000,
  "system_years": 6,
  "system_fund": 3000
}

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.
