Practical questions on this topic

How much discount can I offer?

Calculate costs and minimum margin first. They determine the lowest viable net selling price under your inputs.

Why do discounts erode margin?

Revenue falls while sourcing cost and fixed fees generally stay unchanged.

How do I plan Black Friday promotions?

Calculate contribution at the sale price, and assess demand and applicable price display rules separately.

How do I find the minimum price?

Solve for price using fixed costs, percentage fees and target contribution margin, then verify cent rounding.

Can a lower-margin sale still be useful?

Possibly, if evidenced extra demand or stock clearance offsets lower unit contribution. This tool does not forecast that.

How do discount and margin differ?

Discount is the reduction from regular price; margin is the remaining contribution relative to the sale price.
