Headline discount vs net saving
A headline number answers one question: what percentage or amount is being subtracted from a stated base price. It does not answer whether that base price was fair to begin with, or whether other charges absorb the saving.
Net saving answers the question you actually care about: what is the final amount I pay for this exact unit, with this exact parking and floor, compared to the same unit without the offer? That comparison requires you to hold everything else constant.
1. Confirm the baseAsk whether the discount is calculated on the standard price list or a special festive list price that may already be raised.
2. List every chargeRegistration, GST, parking, floor rise, club and legal charges — write down which are waived and which are not.
3. Compute net priceBase price minus the real discount and waived amounts, plus everything still payable. That is your comparison number.
4. Compare like-for-likeUse the identical unit type, floor band and parking configuration across every offer you compare, including a no-offer baseline.
If a sales team cannot answer where the discount is calculated from, that alone is a reason to ask for the written offer before proceeding.
