eBay repricing strategies: cost-plus, competitor, sales-based and event pricing compared

What are the main eBay repricing strategies?

eBay repricing strategies are the rules that decide how a listing's price changes over time. There are four main families. Cost-plus repricing sets the price from your cost using your own formula. Competitor-based repricing sets the price against what similar listings charge. Sales-based repricing adjusts each listing according to how well it sells. Event pricing makes temporary changes around sale periods. Each has strengths and blind spots, and most sellers end up combining them. The order in which you combine them matters more than the choice of any single one, because it decides which rule wins when two of them disagree.

Repricing, in this guide, means changing the price of a live fixed-price listing, by hand or with software, in response to something that has changed.

How do the four strategies compare?

How does cost-plus repricing work?

Cost-plus is the natural base for sellers who buy each item after a sale or hold little stock. The price is calculated from the current cost: add your markup and fixed costs, then divide by one minus all percentage fees, so eBay's fees come out of the sale price rather than your margin. When the cost changes, the price changes with it.

• Use it when: your cost moves often and you need every sale to stay profitable.
• Watch out for: a formula that ignores the market can price you well above similar listings and stop sales without telling you why.
• Make it safer with: a minimum profit floor and a price circuit breaker that holds unusual changes for review.

The eBay pricing formula guide sets out the full calculation.

Checking cost-plus against the market

Cost-plus tells you the lowest price you should accept, not the price the market will pay. Once a week, compare a sample of your cost-plus prices with similar listings on eBay. If your price sits well above the going rate, you have three choices: accept fewer sales, lower your markup on that product, or stop selling it. If your price sits well below the going rate, you may be leaving money on the table and could raise the markup. Either way, the check turns a blind formula into an informed one without giving up the protection of the floor.

How does competitor-based repricing work?

Competitor-based repricing looks at what similar listings charge and positions your price against them: matching the lowest, sitting a little below a chosen competitor, or staying within a band. It is common on products where many sellers list the same item and buyers compare on price.

• Use it when: the product is identical across sellers and price is the main difference buyers see.
• Watch out for: two repricers chasing each other down. Without a floor, each undercut triggers the next, and both sellers end up selling at a loss.
• Make it safer with: a hard floor from your own cost, and rules that compare total price, item plus postage, from sellers with similar delivery and returns.

Why total price and terms matter

A competitor at £1 less with slow delivery, no returns and weak feedback is not the same offer as yours. eBay names the price among its Best Match factors, but also the listing's quality, its terms such as the returns policy and handling time, and the seller's record, without saying how much weight each carries. Competing on price alone ignores the other things buyers and search weigh.

How does sales-based repricing work?

Sales-based repricing adjusts each listing by its own results. Listings that sell well can carry a slightly higher price; listings that attract views but no sales may be priced a little too high; listings with no views at all usually have a visibility problem that price alone will not fix.

1. Collect enough data. A few days is rarely enough. Look at weeks.
2. Move in small steps. Change by a small amount, then wait for the result before moving again.
3. Change one thing at a time. If you change the price and the title together, you will not know which made the difference.
4. Keep the floor. A non-selling listing never goes below its minimum profit price.

A hypothetical example

Example: suppose a listing priced at £18.99 from a £13.00 cost sells about four units a week, with plenty of views. You raise it in small steps to £19.49 and then £19.99, watching each for two weeks. If sales hold at about four a week, each step adds about 50p of revenue per sale, less the percentage fees on it. A second listing at £24.99 gets views but no sales for a month. You lower it in small steps towards its floor of £22.40 and watch whether sales start. If they do not, the issue may be the listing itself, its photos, title or delivery time, rather than its price.

How does event pricing work?

Event pricing makes planned, temporary changes around periods such as Prime Day, Black Friday and the run-up to Christmas. Supplier costs can fall during these events, demand shifts, and competitors change their prices. Event pricing decides in advance which listings follow those changes and which hold.

• Before the event: choose which listings to follow down, which to hold, and which to pause.
• During: read costs more often; deals end and stock runs out without warning.
• After: reverse every temporary change. A listing left at an event price after its cost returns to normal sells at a loss.

How do you combine repricing strategies safely?

The safest structure is a stack of layers, each working within the limits set by the layer below.

1. Base: cost-plus with a floor. Every price is calculated from the current cost, and nothing goes below break-even plus your minimum profit.
2. Layer: competitor positioning. Where it suits the product, adjust within a band around the cost-plus price, never below the floor.
3. Layer: sales-based adjustment. Small, slow steps up or down by each listing's performance.
4. Layer: event rules. Temporary changes with a clear end date.
5. Guards on everything: currency checks, a ceiling and a swing limit that holds unusual changes for review.

Dropizon is built on the base layer: it reprices from live Amazon readings with your own formula, eBay fees grossed up into the price, a minimum profit floor, optional .99 endings and per-listing overrides, with a reason recorded for every push and every hold. The eBay repricer page explains the settings.

For sellers who source from retailers, one rule sits outside every strategy. eBay allows dropshipping from a wholesale supplier, but listing an item and then buying it from another retailer or marketplace that ships directly to your buyer is not allowed under eBay's drop shipping policy. You stay responsible for delivery and your buyer's satisfaction.

Which combination suits which products?

• Niche products with few sellers: cost-plus with a floor, plus slow sales-based steps. Competitor data is thin and rarely worth chasing.
• Popular branded products with many sellers: cost-plus as the floor, competitor positioning within a band, and careful event rules, because these products move most during sales.
• Cheap, high-volume items: cost-plus with a firm money floor. Pennies matter, and competitor chasing quickly erases them.
• Expensive items: cost-plus with a percentage element in the markup, tighter swing limits, and manual review of large changes.

A repricing strategy checklist

• Start from cost-plus with a minimum profit floor on every listing, recalculated from each new cost.
• Add competitor positioning only where products are identical and price-led, within your floor.
• Use sales data in small, slow steps, changing one thing at a time.
• Plan event pricing in advance, with an end date for every change, and reverse it on time.
• Put guards on every change: currency, ceiling and swing limit.
• Judge each strategy by profit per listing over several weeks, not by sales alone.
