eBay Promoted Listings Calculator

A worked example

You sell an item for $45 with a 4% ad rate. If the sale is attributed to the promoted listing, the ad fee is $1.80. Your final value fee at 13.25% is $5.96, and the fixed order fee is $0.30, so total fees are $8.06 before the cost of the item.

If the item cost you $25, profit is $45 - $25 - $8.06 - $1.80 = $10.14. Without the promoted listing the same sale would have returned $11.94. The ad bought you a sale you would otherwise not have had, at a cost of $1.80.

That is the only question that matters: did the ad produce an incremental sale worth more than $1.80? If the item would have sold anyway, the ad fee is pure loss.

How the fee is triggered

Promoted listings are charged on sales attributed to the promoted listing, not on impressions or clicks. An item that gets promoted, gets seen and does not sell costs nothing. That makes the model closer to commission than to advertising, which is why it suits sellers with thin cash flow.

The ad rate is a percentage of the sale price. It is set per listing and can be changed at any time, but the rate that applies is the one in force when the sale happens.

When promoted listings lose money

The break-even ad rate is your margin percentage. If you make 20% on an item, an ad rate above 20% means a promoted sale loses money on every unit, no matter how many units you sell.

Thin-margin categories are the danger zone. Electronics and media often run single-digit margins, and a 6% ad rate there can erase the entire profit on the order. The same 6% on a handmade item with a 45% margin is cheap.

Before raising the rate, calculate the margin on the specific item, not the average across your catalogue. Averages hide the listings where the ad fee is doing real damage.
