What eBay Promoted Listings Really Cost per Sale

What the ad rate is charged on

eBay’s general campaign help page, read October 5, 2026, sets out the rules:

• You choose an ad rate from 2% to 100%.
• The fee is that rate times the item’s total sale amount, which eBay says includes “item price, shipping, taxes and any other applicable fees”.
• You pay only when the promoted item sells within 30 days of a click on your ad. A click includes interactions such as adding the item to a watchlist or cart, or opening a quick view.
• Ad fees show in the Payments tab in Seller Hub.

That total is the same base as the final value fee, which eBay figures on the item, handling, shipping and sales tax, plus a $0.40 order fee on orders over $10.00 (eBay selling fees). The ad fee is separate and adds to it.

eBay also offers a priority strategy, where you pay per click instead of per sale (Seller Center). Its cost depends on clicks, not on the sale, so it isn’t covered here.

Worked example: 5% on a $50 sale

The example item sells for $50.00 with $8.00 shipping charged and an 8% example sales tax on both (the marketplace charges the rate for the buyer’s address). The buyer pays $62.64. You bought an $8.00 label, paid $12.00 for the item plus $0.96 sales tax when you bought it, used $0.85 of supplies, and drove 6 sourcing miles, valued at the IRS business rate of 76¢ for July 1 to December 31, 2026 (IRS). That rate is a tax-deduction rate used here as a stand-in for your car cost, not what your car actually costs.

Without the ad the same sale nets $41.08 and makes $22.71 profit. Net payout is what lands in your eBay balance after fees and the label; profit is net payout minus what the item, supplies and trip cost you.

The ad fee of $3.13 is 6.3% of the $50 item price, not 5%. The general rule: effective share of the item price = ad rate × total sale amount ÷ item price. Here that’s 5% × $62.64 ÷ $50.00 = 6.26%. The more shipping and tax ride on the sale, the bigger the gap.

The same sale at other ad rates

Every fee is rounded to the cent before adding, as in our calculators (eBay may round differently by a cent):

At 10%, eBay’s two charges together ($8.92 + $6.26 = $15.18) take 30.4% of the item price.

On cheap items the shipping share is larger, so the gap widens. A $20 item with $5 shipping and 8% tax has a $27.00 total; an 8% ad rate costs $2.16, which is 10.8% of the item price. With a $4.00 item cost and $0.85 of supplies, profit drops from $11.08 to $8.92.

The buyer’s address matters too, because sales tax is in the base. Sell the same $50 item to a buyer in a state with no sales tax and the total is $58.00: the final value fee drops to $7.89, the 5% ad fee to $2.90, and the profit at 5% is $20.44 instead of $19.58.

Your break-even ad rate

The highest ad rate a sale can carry before it stops making money is:

break-even ad rate = profit before the ad ÷ total sale amount

For the example: $22.71 ÷ $62.64 = 36.25%. At 36.2% the ad fee is $22.68 and the profit is $0.03; one tenth of a point higher and the sale loses money. That’s the true ceiling, but nobody advertises to make $0.03. A more useful version keeps a profit you’re not willing to give up:

ad rate ceiling = (profit before the ad − profit you want to keep) ÷ total sale amount

Use the total sale amount, not the item price, in the bottom of the fraction. Dividing by $50 instead of $62.64 would put the ceiling for keeping $15 at 15.4%, a rate that actually leaves you about $13.

What the 30-day click rule means for your math

You pay when a promoted item sells within 30 days of a click on its ad, and eBay counts watchlist and cart adds as clicks. The fee follows that click; eBay’s page doesn’t ask whether the buyer would have bought anyway. So treat the ad fee as a cost on every promoted sale, not only on the extra sales you hope the ad brings. If an ad lifts your sales, the extra profit has to cover the fee on all promoted sales, including those that would have happened without it.

eBay also offers two ways to set the rate: a fixed rate that stays where you put it, and a dynamic rate that eBay updates daily to its suggested rate. A dynamic rate can move above the ceiling you worked out, so if you use it, check the rates it applies against your numbers.

A practical check before raising a rate:

1. Find your profit before ads on a typical sale with the eBay fee calculator or the reseller profit calculator.
2. Decide the profit per sale you want to keep.
3. Compute the ceiling with the formula above, using the total sale amount.
4. Keep your rate below that ceiling and compare the ad fees in your Payments tab with the sales the campaign reports.

For how ad fees fit with Store fees, see is an eBay Store worth it; a Store lowers the final value fee in many categories, which raises the ceiling slightly.

Next step

Enter your item, shipping and tax in the eBay fee calculator and type your ad rate into the Promoted Listings field: it shows the ad fee on the full total, your net payout and your profit. Set the rate back to 0% to see the same sale without the ad.
