- Batch table: add many products with their own discounts and see total profit and overall margin for the whole sale.
- Reverse mode: enter your list price, cost and the minimum margin you accept, and get the largest discount you can safely offer.
Margin vs markup
Margin = profit divided by sale price. Markup = profit divided by cost. A 25% margin needs a 33.3% markup. Always decide discounts from margin, because margin tells you what you actually keep from each sale.
Frequently Asked Questions (FAQ)
What is the difference between margin and markup?
Markup is profit as a share of cost price, while margin is profit as a share of selling price. This tool shows both so your sale price stays profitable.
How do I find the maximum discount I can give?
Use reverse mode: enter your list price, your cost and the minimum margin you accept. The tool computes the highest discount that still keeps that margin.
Can I compare discounts for several products at once?
Yes. The batch table lets you add many products with their own cost, list price and discount, and totals profit across the whole list.
