eBay pricing and repricing: price from a target profit, competitor prices and automatic rules (2026)

In dropshipping, price is set twice: at the first listing and every time the Amazon price changes. Get the first wrong and the item doesn't sell or sells at a loss; try to do the second by hand and you can't watch a hundred listings. This guide covers what must be inside the price, three pricing strategies, positioning against competitors, repricing rules (mode, guard, floor and ceiling) and common mistakes. Fee figures follow eBay's 2026 table.

1. What is inside the price?

The sale price must cover: supply cost, supply tax (without an exemption), the eBay final value fee (on the tax-inclusive total), the fixed per-order fee, an ad share, a returns allowance and the target profit. Because the fee percentage depends on the price itself, the price is found by division:

Price = (Cost × (1 + supply tax) + fixed fee + target profit) ÷ (1 − fee rate × (1 + sales tax) − ad share − returns allowance)

Example (no store 13.6%, fixed $0.40, buyer tax 8%, supply tax 8%, ad and returns 0):

Item	Value
Supply $16 + 8% tax	$17.28
Fixed fee	$0.40
Target net profit (30% of cost)	$4.80
Divisor: 1 − 0.136 × 1.08	0.853
Sale price	≈ $26.35
Check: fee 0.136 × 28.46 + 0.40	≈ $4.27 → net ≈ $4.80

The Break-even and Target Price Finder does the same with your numbers; the Profit Calculator shows the waterfall. If you charge the buyer for shipping separately, remember that eBay's fee base includes the shipping amount.

2. Three strategies: net profit, margin, tiered

Strategy	Definition	When
Target net profit (percent of cost)	After all costs, keep X% of the item cost	Multi-item stores; automation-friendly; Sellerviva's default
Target margin (percent of sale price)	Net profit equals X% of the sale price	Pricing items one by one; comparing with competitors
Tiered	A different percentage per cost range: high on cheap items, low on expensive ones	So cheap items keep a real amount and expensive ones stay competitive

The same "30%" gives two results: 30% of cost on a $16 item is $4.80; 30% of the sale price on the same item is about $9.60 and a much higher price (about $32). Know which one you use. Tiered table example (common; adjust to your goal):

Cost range	Target net profit (percent of cost)
$0–10	35%
$10–30	25%
$30–100	18%
$100 and above	12%

Set a minimum amount independent of the percentage (common: at least $3–5 per sale); otherwise 35% on a $6 item means $2.

3. Positioning against competitors

• Know the range: use eBay's "sold items" filter for the last 30 days' sale price range (Product research 101 §3). Aim for the middle of the range, not the bottom.
• The race to the bottom finishes both sides: the competitor drops $1, you drop $1; in the end you both sell at a loss. Never go below your floor.
• Non-price differences affect ranking and conversion: 1-business-day handling, 30-day returns, the Top Rated badge, free shipping, a good title and photos. At the same price these put you ahead.
• Free shipping psychology: bury shipping in the price; the eBay fee base already includes shipping, so cost doesn't change and conversion rises.
• Best Offer: if enabled, set auto-accept and auto-decline thresholds from your floor; never accept a below-floor offer even manually.
• Promoted Listings: the ad rate is the "ad share" in the price formula; price promoted listings accordingly.

4. Repricing: mode, guard, floor and ceiling

The Amazon price changes during the day; if your listing stays at the old price you either sell at a loss or miss the opportunity. The rule trio:

Decision	Options	Recommendation
Mode	Off · Propose (apply on approval) · Automatic	Start with "propose" on a new store, switch to "automatic" after a few weeks
Guard (max change percent)	Changes above this go to approval even in automatic mode	10–15%; keep Amazon's temporary price spikes off your listing
Floor and ceiling	Floor = break-even + minimum profit; ceiling = top of the competitor range	Never below the floor; above the ceiling visibility drops

When the Amazon price rises, update immediately; delay is a loss. When it falls, you don't have to lower the price; your profit grows, but if competitors lower theirs you slip in ranking — look at the range. Example: an item costing $16 sold at $26.35; when Amazon goes to $18 the new price is ≈ $29.59 (+12%): with a 10% guard it goes to approval and you apply it; at $14 it is ≈ $23.12 (−12%): if the competitor range is $24–28, $25.99 works too.

5. Stock and handling rules are part of pricing

• Quantity 0 when out of stock: an accidental sale and an "out of stock" cancellation are defects (returns and defects guide); this rule comes before the price rule.
• Critical stock threshold: set the eBay quantity to 0 when Amazon stock falls below a set number; don't take order risk on the last few units.
• Maximum handling time: don't publish items with long Amazon delivery; your handling time can't be kept.
• eBay quantity should always be the smaller of the desired quantity and Amazon stock.

6. Common mistakes

• Leaving tax and ads out of the formula: 8% tax + 2% ads move the price up by about 3–4%; leave them out and that's lost profit.
• Mixing percent of cost with percent of sale: the same number, two different prices.
• Automatic mode without a guard: Amazon's few-hour price error lands on your listing; buyers see it.
• Setting the floor at break-even: the floor is the minimum-profit point, not the zero-profit point.
• Being the cheapest: the middle of the range plus a good listing sells more than the lowest price.
• Forgetting the returns allowance: at a 4% return rate that's about $0.40–0.70 per sale (returns guide §7).
• Not pushing price changes to the listing: product selection is once, price updates are daily; it can't be done by hand, it needs a rule.

7. How it works in Sellerviva

• Automation → Price and stock rules: the "update price when the supplier cost changes" rule is off / propose / automatic; the price change guard (max percent) sends larger changes to approval even in automatic mode. Supplier data is evaluated on every sync and decisions are written to the audit log.
• Profit target (net): the sale price is computed automatically; after the eBay fee, ads, tax and the fixed fee, you keep the percentage of item cost you set as net profit. The tiered profit table gives a different target per cost range.
• Net profit cost model: eBay fee (estimate), fixed fee per transaction, source purchase tax, ad share; the "Net profit" column on the Products page uses these inputs.
• Reprice now: the automatic scan visits each item every 12 hours; if you changed the profit rate, this button recalculates without waiting.
• Stock rules: set quantity to 0 when out of stock (default automatic), end the listing, critical stock threshold, maximum handling time, eBay stock quantity.
• Eligibility profiles: minimum and maximum price, minimum margin; an item that fails a rule is not listed.
