Profit, margin and break-even once every required input is known.
Know your real margin before you buy the stock
Sellsavo puts a fee-by-fee profit breakdown next to the price on supported product pages: commission, fulfilment, storage, VAT, returns and ads. Every line shows its formula, source and date. If a required input is missing, the panel shows “—” instead of inventing a zero.

Three steps from product page to a decision
Open a product
The panel reads the price, category and size the page shows — on the page you opened, and nowhere else.
Add what the page can’t know
Your unit cost, inbound shipping, ad share. If a required fee can’t be determined, Sellsavo asks for it instead of inventing it.
Read the answer in numbers
Profit, margin, ROI, break-even price and a verdict. Set a target margin to see the price that hits it, then export the calculation to CSV with its assumptions.
What the panel says
Every incomplete or uncertain number has one sentence and a next step. These are the exact lines in the panel.
Missing size or weight
Enter the package dimensions and weight to calculate fulfilment and storage.
Missing cost
Enter the unit cost to see profit and margin.
Price not read
Couldn’t read the price from the page. Enter it manually.
Incomplete
Calculation incomplete — profit and break-even appear after the required fields are filled.
Estimated
Estimated fee — no public rate card. Confirm it in your seller account.
Secondary source
Fee from a secondary source. Confirm it in your seller account before a large order.
Outdated
This fee table is outdated. Check the current rates in your seller account.
Verified
Fee taken from the marketplace’s published rate card.
Fulfilment entered by you
For this marketplace, enter fulfilment and storage yourself.
Unsupported page
This page isn’t supported. Open a product page on a supported marketplace.
Search page
Click “Analyze results” to see the price corridor and sponsored share.
Couldn’t read the page
Couldn’t read this page. Refresh it, or enter the values manually.

Every number shows its work
Each fee table carries its source, its effective date and one of these labels. The panel and this site show them on every calculation.
- Verified
- Taken from the marketplace’s published rate card, with its effective date.
- Secondary source
- From a reliable secondary source. Confirm it in your seller account.
- Estimated
- A reasoned estimate where no public rate card exists. Labelled every time.
- Outdated
- Known to be older than the latest change. Check current rates before ordering.
We’d rather show “—” than a wrong number
Many calculators quietly fill unknowns with zero. Sellsavo doesn’t. If the package size or your shipping cost is missing, profit, margin and break-even stay hidden and the panel says exactly which input is needed. The known part of the breakdown stays visible.

Then decide: take it, negotiate or walk away
Below the profit, Sellsavo stress-tests the deal and tells you what would have to change. Included in the free plan. It is an economics model built on your inputs — it does not forecast demand, ranking or sales.
Stress test
Price −10%, cost +10%, ads +5 pp, returns +10 pp. Each shock is recalculated through the same fee engine, not estimated with a rule of thumb.
Price −10%−AED 14.90Cost +10%−AED 4.20Worst caseAED 18.40Economics resilience
A deliberately coarse 0–100 score from margin, break-even buffer, worst-case profit and ROI. Fee-data quality is shown next to it, never blended in.
Resilience55/100Deal verdict
Take, negotiate, risky or reject, with explicit thresholds. Estimated, outdated or manual fee data can never produce “take”.
Negotiate / improve termsNegotiation brief
When a moderate change fixes the deal, you get exact targets — cost no higher than X, price at least Y — ready to copy into a message to your supplier.
Purchase cost: no higher thanAED 36.40Selling price: at leastAED 155.00
Illustration: the figures in these cards are illustrative and show the shape of the output, not a calculation.
Everything you check before you list or restock
Profit panel
Commission tiers and minimums, FBA/FBN by size tier, storage, VAT on fees, refunds and ads — in the store’s currency.
Break-even and target price
The lowest price that still breaks even, and the price that hits your target margin. Your listed price is never changed.
Decision tools
Stress test, resilience score, deal verdict and negotiation brief, all recalculated through the fee engine.
Search analytics
On a search page: median price, price corridor, sponsored share, average rating and a sortable table you can export.
Listing review
A heuristic check of the listing fields visible on the page, with a coverage score. It doesn’t certify compliance or predict sales.
Landed cost from China
On 1688, Alibaba and Made-in-China: quantity price tiers plus your freight, duty, agent and payment fees, saved as your unit cost.

Where Amazon publishes no FBA table we could verify (Mexico, Brazil, Türkiye), you enter the FBA fee and storage yourself. Amazon.in is not supported yet. UK and EU fuel in this build is 2% from 2 November 2026. The UK and Germany festive peak (15 October 2026 to 14 January 2027) is included on the standard grid; Germany uses the non-CEP domestic rate. Parcel rates for Amazon’s selected categories are not split out. Mercado Libre, Flipkart, Shopee and Lazada rates are estimates from secondary sources — the panel lets you type the exact rate from your seller center. Full fee-data status with sources
Your costs never leave your browser
Local by design
Costs, prices and supplier calculations live in the extension’s local storage. No Sellsavo account, no server holding your data.
Reads only the page you open
No crawling, no background requests to marketplaces, no automated clicks. It never runs on checkout, sign-in, account or seller-console pages.
No tracking
No analytics or cookies in the extension or on this site. During the free beta the extension does not call a payment or licence server.
Free beta. Pro is $0.
Free beta. Additional paid features may appear in the future. We will say so on this site before anything is charged. The Free and Pro plans stay in the product so billing can return without a rewrite.

Questions
How accurate are the fees?
We model each marketplace’s published or best-available rate card, labelled verified, secondary or estimated with its effective date. Your account can still differ (category exceptions, promotions, negotiated rates), so treat results as an estimate and confirm big decisions in your seller account. Where you know the exact fulfilment fee, you can enter it.
Why isn’t it in the Chrome Web Store yet?
Publication is in preparation. Until then you install the early-access build manually: unzip it, turn on Developer mode in chrome://extensions and click “Load unpacked”. It takes about a minute. Manual builds don’t update themselves; download a new build from this site when one is out.
Is a manual install safe?
The extension asks only for the supported marketplace and supplier sites and for local storage. It does not contact a payment service during the free beta. The install page lists exactly what it can access. Chrome may remind you about developer-mode extensions; that is normal for manual installs.
What’s free, and what’s in Pro?
During the free beta both plans are $0. Free is the profit panel, formulas, break-even, decision tools, CSV and the web calculator. Pro adds search analytics, listing review and landed cost from Chinese suppliers, and those are included at no charge. Paid features, if we add them later, will be announced here first.
Can I buy Pro now?
No. Checkout is off. Pro costs $0 in this beta. We will not turn on a charge without a notice on sellsavo.com.
Does it predict sales or tell me what to sell?
No. Sellsavo models unit economics from the page and your inputs. Search analytics summarises what the results page shows you; nothing in Sellsavo forecasts demand, ranking or conversion.
Does it touch my seller account?
No. It reads the product or search page you open, makes no background requests to marketplaces, and never runs on checkout, sign-in or seller-console pages.
Why can the numbers differ from my seller account?
We use the published or best available rate card and always label it. Your account can have category exceptions, promotions or negotiated rates. Confirm a large purchase in the seller account. Where you know the exact fulfilment fee, enter it.
Why does the panel sometimes show “—”?
Because we do not substitute zero for an unknown. If package size, weight or another required input is missing, profit and break-even stay hidden and the panel says exactly what to fill in. The known part of the breakdown stays visible.
How do I send feedback?
The public beta is already free. Send a note about what matched your seller account and what did not. There is no promo code and no payment.
Which browsers?
Chrome, tested on every build, and other Chromium-based browsers via manual install. A test build for desktop Firefox 142+ exists but is unsigned and not on AMO.
