Pillar four

The Toolkit: turn a lesson into a number on your land.

One Excel workbook with every calculator in the school, keyed to your country, hectares and Major. Type in the yellow cells and read the answer.

A desk with a laptop spreadsheet, calculator and input sheets

How the calculators work

103 calculator codes, built as working sheets in one workbook.

Most Majors share the same tools, such as the Enterprise Budget and the Market Price Comparator, set up for their commodity. The Directory sheet inside the workbook maps every code to its sheet. Open it in Excel, Google Sheets or LibreOffice.

1Yellow cells are yours
Type only into yellow cells. White cells calculate. Every input arrives pre-filled so the calculator answers before you change anything.
2Set your country once
The Settings sheet holds your country, hectares, Major, venture name and location, and reads the exchange rate. Every calculator reads from it.
3Read the dated benchmark
The Benchmarks sheet carries dated prices from the data layer with year and source, so you can see how old a default is.
4Follow the chain
The Core Course calculators are linked: start-up capital feeds the loan, the loan feeds the cash flow, and both feed break-even.
5Plan your people
T-C-08 People and Labour Cost sets out your team, its cost, the jobs held locally and the money reaching the community.
6Take the next step
Where a calculator ends in an action, such as moving a load or registering the venture, the sheet names the partner platform that does it.
