What this planner helps you decide
Best for
Businesses checking a customer price against confirmed Australian GST treatment.
Outputs
Required retained and displayed prices, tax component, gross profit, gross margin and current-price gap.
Start here
Confirm the taxable-sale scope and applicable rate, then enter cost and target retained margin.
Use a different tool when: Do not use this to set a price for a target gross margin; use Target Margin & Pricing Planner for that decision. Use this tool to set a retained margin using confirmed taxable-supply and GST-inclusive or exclusive treatment.
Price & margin
Australia GST-aware Pricing: required retained and displayed prices
Required retained and displayed prices, tax component, gross profit, gross margin and current-price gap.
GST-aware price assumptions
Use one GST basis. Inputs do not determine tax.
Your numbers stay in this browser
Enter per-unit cost on the selected GST basis.
Gross profit share retained before GST.
Mixed and input-taxed supplies fail closed.
Optional comparisonAdd a comparison value only when it helps your decision.
Optional comparison price on the selected GST basis.
Tax treatmentKeep the warning when treatment is uncertain.
Confirm whether the entered cost includes tax.
This bounded workflow supports Australia only.
Enter turnover for this exact measured period.
Enter turnover for this separate measured period.
Choose the confirmed status; uncertainty keeps an authority warning visible.
Choose No when tax paid remains in effective cost.
Required for recoverable GST in a tax-inclusive cost; separate from output rate.
Controls whether displayed price adds tax to retained revenue.
Price decision
Protect the entered retained margin on revenue excluding GST; treat the customer-facing tax amount separately.

When this estimate can be misleading
- This planner does not determine GST registration, taxability, exemptions, recoverability, place of supply, nexus or filing liabilities.
- The reviewed GST rate is selected only from supported jurisdiction, supply-class and effective-period branches; unsupported cases stop instead of guessing.
- The turnover comparisons are review signals from official period rules, not registration conclusions or effective-date advice.
- Gross profit is a per-unit pricing measure before fixed costs, overhead allocation, income tax, financing and demand effects.
- Current displayed price must use the same inclusive or exclusive tax basis selected in the planner.
- Use the displayed-price result only after confirming the sale classification, registration position and applicable rate.

Frequently asked questions
How do I set a retained margin using confirmed taxable-supply and GST-inclusive or exclusive treatment?
Compare the required displayed price with the current customer price and document the confirmed tax basis.
Does Margin101 choose the applicable GST rate?
No. The reviewed default applies only to the documented taxable-supply scenario. Confirm the rate and treatment for the actual sale.
Does Margin101 store my numbers?

Is this tax or accounting advice?
No. It is an educational pricing scenario. Check the actual transaction with the relevant authority or a qualified adviser.
Which planning assumptions should I stress-test?
