The straight answer
A discount changes revenue, margin and required sales volume; it should be modelled against variable costs and expected conversion lift.
A reliable use of Discount Pricing Guide starts by naming the decision, then checking the assumption most capable of changing it.
What matters most
| Priority | How to apply it |
|---|---|
| Main driver | A 20% discount requires more than 20% extra units to preserve gross profit. |
| Downside risk | Apply discount to the correct GST basis. |
| Verification point | Permanent promotions can train customers to wait. |
How to use this guide
Compare the normal selling price, discount, variable cost, payment cost, return allowance and GST treatment on the same sale. For this page, the comparison is only valid when the monetary basis and timing are consistent.
- For discount pricing guide, name the decision first so the model does not drift into a different question.
- Validate the base case against this page-specific point: A 20% discount requires more than 20% extra units to preserve gross profit.
- Build a realistic downside scenario around this constraint: Apply discount to the correct GST basis.
- Before acting, verify this final check against current statements, contracts or official guidance: Permanent promotions can train customers to wait.
Worked example
If an item sells for $100 with $60 variable cost, contribution is $40; at $80 sale price contribution is $20, so unit volume must double to preserve contribution.
The discount pricing guide example is a model, not a forecast. Keep the original figures visible and change one commercial input at a time—such as price, rate, term, fee or volume—so the reason for the difference is obvious.
What can change the answer
For Discount Pricing Guide, the main sources of variation are selling price, GST basis, variable cost, payment fees, fulfilment, returns, discounts, overhead and sales volume; record which of those changed between comparisons because the result cannot adjust for an unmeasured change or an input that was never entered.
- For discount pricing guide, confirm whether every amount is gross or net and whether GST is included, excluded or not applicable.
- Separate fixed costs, variable costs, one-off costs, interest and fees instead of hiding them inside one total.
- Use actual payment dates and matching weekly, monthly or annual periods so timing does not distort the comparison.
- Stress-test the result against the risk highlighted on this page: Apply discount to the correct GST basis.
Common mistakes
- Changing a plan from a single discount pricing guide result before a repeatable baseline exists.
- Ignoring the page’s main limitation: Apply discount to the correct GST basis.
- Changing course before checking this review signal: Permanent promotions can train customers to wait.
- Choosing the most attractive headline figure while ignoring cash flow, fees, timing or the cost of being wrong.
