Understand the topic

What you need to know.

The farm planning tools on this site turn your inputs into production, cost, break-even, cash and risk figures, all from one calculation engine. This page explains what each tool answers, what it cannot know, and how to feed it honest numbers from your own records. A tool is only as good as its weakest input, and it is allowed to tell you not to build yet.

Teaching revised 2026-09-24. Source-linked editorial synthesis; this date does not imply independent technical review.

Part 01

What a calculator knows, and what only your farm can tell it

Every tool here runs on the same versioned engine, so a cost per kilogram in one tool matches the same figure in another. The engine does the arithmetic. It does not know your compost, your rooms, your electricity tariff or your buyers.

That split decides how to use the results. The tools keep production, saleable quantity, sales, realised price, operating result and cash movement apart, because each one answers a different question. Defaults are visible and editable, prices are either dated by you or left blank, and subsidy is never counted as operating revenue.

A result means something only when its inputs carry a label: measured on this farm, taken from a named document, or assumed. Keep that label beside every input. A blank field is more honest than a national average typed in to make the page look complete.

The results come from an educational pre-tax model. They are not a quotation, a bank-approved DPR, a subsidy decision or a promise of profit, and they can return no-go.

From your records to a decision

RecordsBills, crop diary, harvest weights and buyer slips.
Labelled inputsEach marked measured, sourced or assumed, with a date.
Base resultProduction, cost per sold kilogram, break-even and cash need.
Downside runsLower yield, lower price, higher cost, slower payment.
DecisionGo, conditional, pilot or no-go.

Part 02

Which tool answers which question

Pick the tool by the decision in front of you, not by the headline number you hope to see.

Feasibility check: tests the whole project across biology, climate, technical set-up, infrastructure, raw material, market, finance, operator and risk, and returns go, conditional, pilot or no-go.
CAPEX planner: builds an asset register with source type, date, place and GST treatment, and keeps contingency and working capital separate. It does not supply prices.
OPEX planner: sorts running costs into variable, semi-variable, fixed and step-fixed, so you can see which ones move with output.
Cost per kg calculator: gives variable, operating and fully loaded cost per sold saleable kilogram.
Production planner and crop scheduler: work back from the saleable output you want through yield, crop units and room use, and stagger rooms without assuming the same harvest every day.
Break-even calculator: the quantity, realised price and room use at which contribution covers fixed cost. Profitability calculator: revenue, contribution, operating profit or loss and finance, shown separately.
Cash-flow planner and working-capital calculator: monthly receipts and payments, and the cash tied up in stock, crops in progress and unpaid invoices, less supplier credit.
Sensitivity analysis: a yield and price grid, plus a chart ranking which assumption moves the result most.
Market-price evidence tool: stores your dated rate by market and grade with where it came from, or shows plainly that no checked local price is available.
Electricity, labour and compost make-or-buy tools: cost one input in detail, whether power from metered use or duty cycle, labour of every kind, or bought against home-made compost.

Part 03

Feed the tools inputs you could defend to a lender

Enter each input in the form the tool asks for, and note where it came from. Replace published figures with your own records as soon as you have a finished crop.

YieldStart low within a published range. For button mushrooms, Table 7.1 of the ICAR-DMR manual gives 10 to 15 kg per 100 kg compost for the long method and 18 to 25 kg for the short method.
Saleable shareWeigh the harvest, then weigh what was sold, rejected and left unsold. Never enter harvested kilograms as sold.
PriceEnter a dated rate from a named buyer for a named grade, less commission and transport. Leave the field blank rather than borrow an online retail price.
Crops per roomEnter the number your rooms will really carry. The manual's economics model assumes 6 crops of 60 days per room each year in controlled rooms, while some seasonal growers take one crop a season.
ElectricityUse metered kWh, or each machine's power times its duty cycle and running hours, with your tariff, demand and fixed charges.
LabourInclude permanent, daily-wage, piece-rate, family and owner labour. Unpaid family work still has a value at the local wage.
SubsidyLeave it out of operating revenue, and run every case without it.

Part 04

Keep four records, because the tools read nothing else

The tools are only as current as the records you keep. Four records cover almost every input, and each answers a different question.

An investment register lists assets, installation, delivery, taxes and exclusions: what must be funded before the farm operates. A crop cost sheet lists the inputs, labour, utilities, packing and shared overheads each crop consumed. A sales ledger lists accepted grades, quantities, prices, returns and deductions: the revenue actually earned. A cash calendar lists actual and expected receipts, payments and loan instalments: whether the farm can pay each bill on the day it falls due.

Weigh the harvest before grading and again after, and write both weights in the crop diary with the date. NHB's 2018 model report asks every applicant to describe the farm records they will keep, and its self-declaration commits the applicant to maintain proper farm accounts. The records that feed the tools are the same ones a bank and an inspection will ask to see.

After the first complete crops, put what actually happened back into the tools. Do not raise a forecast to match an income you hoped for.

Part 05

Read the result before you act on it

IfBreak-even kilograms are more than your rooms can produce at a low yield.: ThenThe size or the cost structure does not work yet. Change the plan, not the yield.
IfThe break-even calculator finds no break-even point.: ThenNet price per kilogram is at or below variable cost, so extra volume only adds loss. Fix price or cost before anything else.
IfThe year shows a surplus but the cash-flow planner shows a negative month.: ThenThat lowest balance is working capital you must arrange before starting, from your own funds or an agreed limit.
IfThe sensitivity chart shows one input moving the result far more than the others.: ThenSpend your next effort on evidence for that input: a trial crop, a firm quotation or a buyer's written rate.
IfThe feasibility check returns pilot.: ThenRun a small number of crops at small scale, record them, and run the tools again with measured figures.
IfYour own compost looks far cheaper than bought compost.: ThenCheck that straw, manure, labour, power and the yard are each counted once, and that the yield on your own compost is measured, not assumed.

Part 06

Input mistakes that make a weak plan look strong

Common mistakeSetting room use at 100 per cent.

Do this insteadRooms stand empty while they are filled, emptied and cleaned. Enter turnaround time and the share of the year each room is really in crop.

Common mistakeTyping in a price seen online, or a national average.

Do this insteadUse your own dated buyer record, or leave the price blank until you have one.

Common mistakeMultiplying the nameplate power of every machine by every hour of the year.

Do this insteadUse a meter reading, or power times duty cycle times the hours each machine actually runs.

Common mistakeLeaving family and owner labour at zero.

Do this insteadValue it in the labour tool, which shows both a cash view and an economic view.

Common mistakeComparing two projects built on different cost boundaries.

Do this insteadUse the project comparison tool, which applies the same method to both while keeping species, system, cycle and market differences visible.

Common mistakeTreating one run of the model as the answer.

Do this insteadSave the base case, run the low cases, and keep all of them with the date and the inputs used.

Yield → saleable production → revenue

Cost side

Power + labour + compost + packaging + transport + finance

Cost → contribution → operating result

The model can say: do not build this yet.

No guaranteed return, monthly-income promise, timeless market price, assumed subsidy or 100% utilization is published.
