01
Define the revenue model
Write down what creates revenue and how often it repeats. Use realistic units, not a best-case month.
🚀 Business Planning Journey
Test the economics before you scale the work
Use a simple sequence: revenue assumptions, variable costs, fixed costs, break-even, pricing and scenario testing. The calculator outputs help structure the model but do not predict demand.
The decision pattern
Start with a measurable goal, model the relevant inputs, compare scenarios and verify any current rule or source before acting.

What this page does not do
It does not tell you one universal “best” answer. Different inputs, time periods, locations and constraints can change the result. The linked tools are calculators, not guarantees.
Five-step decision workflow
Use the steps in order, then repeat the steps after changing one important assumption.
02
Calculate break-even
Estimate the sales volume or revenue required to cover fixed and variable costs.
03
Set a sustainable price
For freelancers and service businesses, price needs to reflect billable time, non-billable work, overhead and desired take-home income.
04
Model taxes and transaction costs
Add the relevant tax/GST and other cost assumptions separately instead of hiding them inside one percentage.
05
Stress-test the plan
Change revenue, price, utilisation and costs. The purpose is to find fragile assumptions before committing cash.
Scenario testing
A single output can hide how sensitive the result is to your assumptions.
Practical rule: Build low/base/high cases for revenue and utilisation. If the result changes dramatically from a small assumption change, treat that as a signal to gather better real-world data. Record the assumptions next to the result so you can reproduce the comparison later.

Important: Current rates, tax rules, health guidance, market returns, crop outcomes and other external conditions can change.

This is a management model. It excludes GST, income tax, financing, working-capital timing and one-off costs unless you include them in your assumptions. The stress case is intentionally mechanical, not a forecast.
