80 is the example result. Read it using the units and relationship stated below.
Volume Discount uses original price, discount (%).
Protecting contribution before accepting a price
For volume discount, the relationship is Discounted unit price = original unit price × (1 − discount percentage ÷ 100). The amount depends on the supplied original price, discount (%), rather than a live market price or a value imported from another record. A quote can meet a revenue target and still leave too little to cover delivery. Separate the selling-price denominator from the cost denominator: margin and markup answer different questions. A discount changes contribution even when the supplier cost stays fixed.
What the model includes
Discounted unit price = original unit price × (1 − discount percentage ÷ 100). A pricing review should retain the supplier cost, sale price and the reason for any allowance. Returns, payment charges, delivery and tax require explicit treatment; they should not disappear inside a percentage labelled profit. Compare the proposed price with the customer agreement and delivery capacity. A mathematically achievable margin does not establish that buyers will accept the offer.
Example with the supplied inputs
Original price: 100; Discount (%): 20. Result: 80. The values are illustrative.
Compare one changed input
Original price changes from 100 to 110. The result becomes 88. All other inputs remain fixed.
Calculation rule
Discounted unit price = original unit price × (1 − discount percentage ÷ 100).
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Original price | 100 | Use original price on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Discount (%) | 20 | Enter discount (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
Output: 80 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Original price, Discount (%). Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Original price on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 80.
Change Original price from 100 to 110 while keeping every other value fixed. The result becomes 88. This comparison isolates that input; it does not forecast how other variables will respond.
