eBay Promoted Listings: what an ad rate really does to profit

The ad rate looks small next to the final value fee — but it comes straight out of a margin that fees, VAT and postage have already squeezed. Here's the same listing with and without promotion.

The problem

eBay quotes ad rates against the sale price, but you experience them against your profit. A "3%" ad rate on a listing with a 15% true margin is a 20% profit cut. Suggested ad rates don't know your margin — they can't tell you whether promoting is affordable.

The same listing, promoted and not

A £24.99 clothing item (cost £9.50, £2.70 postage, business seller, 3% ad rate when promoted):

Profit — organic sale
£6.80
Profit — promoted sale
£6.05
Ad fee at 3%
£0.75
Profit given up
11%

A 3% ad rate costs £0.75 on this sale — 11% of the listing's profit. Margins are 32.6% organic vs 29.0% promoted.

The rule of thumb

profit cut % ≈ ad rate ÷ true margin × 100 e.g. 3% ad rate ÷ 15% margin ≈ 20% of profit gone per promoted sale
Ad rate as a share of margin, not of price, is the number that predicts whether promotion is survivable.

Assumptions

  • Standard (cost-per-sale) Promoted Listings; the ad fee applies to the attributed sale shown.
  • Clothes, Shoes & Accessories category, VAT-registered business seller, domestic sale, verified UK rate card.
  • The ad fee is charged on the total sale amount, consistent with the final value fee base.

Frequently asked

How is the Promoted Listings fee calculated?
For standard promoted listings you set an ad rate as a percentage of the sale. When a sale is attributed to the ad, that percentage of the total sale amount is charged on top of your normal fees.
What ad rate should I set?
Work backwards from margin, not from eBay's 'suggested' rate. If your true margin is 12%, a 5% ad rate hands over nearly half your profit. Run your listing through the calculator with the ad rate on and see what's left — that's the only honest answer.
Do I pay the ad fee on every sale?
Only on sales attributed to the promotion (typically a click on the promoted placement within the attribution window). Organic sales of the same listing don't carry the ad fee — which is why blended ad cost per order is worth tracking separately.
Is promoting worth it?
It can be — extra volume at a thinner margin can beat no volume. The failure mode is promoting a listing whose margin was already thin, where the ad rate takes it negative. Check the margin first, then decide.
