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 and displayed price under a confirmed Singapore GST scenario?
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?
