eBay Sales Calculator: From Monthly Volume to Real Profit (2026)

A store with 1,200 listings that takes 150 orders a month at a $34 average order value bills $5,100 in sales. Without an eBay Store subscription, about $852 of that is left after eBay's fees and the cost of goods. With a Basic Store on yearly billing, the same month leaves about $1,158. Most eBay fee calculators price one order at a time, so they never show you that gap. This eBay sales estimator works at the level of a month: orders, catalog size and subscription together.

• Four lines do the work: gross sales, eBay's cut, cost of goods, and what is left.
• Three costs only appear at monthly level: insertion fees on your whole catalog, the Store subscription, and the lower final value fee a Store brings.
• The Store decision is arithmetic. In the worked examples below, a Basic Store adds about $306 a month to the take-home of a 1,200-listing store.
• Catalog size is the real lever once you work backwards from a take-home target.

Why an eBay sales calculator is a volume question, not a per-order one

Per-order math is well covered. For a single sale, our eBay fee formula with fee tables and the per-order profit calculator break it down to the cent. This page starts one level up, because three costs do not exist at the single-order level, and they decide whether a month was worth trading.

The first is insertion fees. eBay charges them on listings you create and on every monthly renewal of a Good 'Til Cancelled listing, not only on items that sold. A seller with 1,200 live listings and 150 sales is charged on the catalog, and a per-order tool never sees the other 1,050. The second is the Store subscription, a flat monthly cost that only makes sense against a month of listings. The third is the final value fee rate itself, which drops for sellers with a Basic Store or higher.

There is also a ceiling. Your order count is capped by your monthly selling limits and by how many listings you run. Modeling 275 orders a month is fiction if your account can only list and sell a fraction of that, so check your limits in Seller Hub before you build a forecast on the arithmetic here. If you want the wider picture of the tools that sit around this calculation, our comparison of eBay seller tools covers the categories.

The four-line eBay sales calculator

Strip the spreadsheets away and the model is four lines:

1. Gross sales = orders × average order value (item price plus shipping charged)
2. eBay's cut = final value fees + (orders × per-order fee) + insertion fees + Store subscription
3. Cost of goods = orders × (supplier price + supplier shipping)
4. Take-home = gross sales − eBay's cut − cost of goods − any other costs, such as ads

Two definitions keep the output honest. eBay charges the final value fee on the total amount of the sale, which includes the item price, shipping charged to the buyer and sales tax. eBay collects that sales tax and passes it on, so it is not your revenue, but you still pay the fee on it. The examples below leave sales tax out to keep the math readable, which means the real fee line runs a little higher in states with sales tax. And orders means orders, not units: a two-item combined order pays one per-order fee, which is a small reason sending a combined invoice is worth the thirty seconds.

The 2026 constants for US sellers

These come from eBay's selling fees page for sellers without a Store and its Store fees page, as of Sep 2026. They cover most categories. Some categories use different rates, so check yours.

Every plan adds a per-order fee of $0.30 on orders of $10 or less and $0.40 on orders over $10. Our guide to how much eBay takes on a sale covers category exceptions and international fees.

When an eBay Store pays for itself

Most "is a Store worth it" debates only count insertion fees. The bigger saving at volume is the final value fee: a Basic Store cuts the most-categories rate from 13.6% to 12.7% on items up to $2,500. That is 0.9 points of every sale, before any insertion saving.

Run the full-time store from the introduction both ways. Without a Store, it pays $693.60 in final value fees and $332.50 in insertion fees on the 950 listings above its free 250. With a Basic Store on yearly billing, it pays $647.70 in final value fees, $50.00 in insertion fees on the 200 listings above its 1,000 allowance, and $21.95 for the subscription. eBay's cut falls from $1,086.10 to $779.65 a month, a difference of $306.45. That assumes none of the listings sit in eBay's select categories, which get a bigger allowance.

Small stores are different. A side store with 300 listings pays $17.50 in insertion fees without a Store. A Starter Store on yearly billing would cost $4.95 plus $15.00 in insertion fees, a little more, and it does not lower the final value fee. For that store, no Store is the cheaper choice. Our guide to choosing an eBay Store tier goes through the other benefits each tier brings.

Worked examples: 40, 150 and 600 orders a month

Three stores with the same assumptions: cost of goods at 62% of gross sales, every order over $10, every item under $2,500, every listing Good 'Til Cancelled (so each counts against the allowance every month), and no sales tax. Each store uses the cheapest plan for its size from the table above.

The keep rate rises with size for two reasons you can see in the table. The Store tiers lower the final value fee rate, and the $0.40 per-order fee weighs less on a bigger order: it is 1.4% of a $28 order and under 1% of a $41 order. Raising average order value does more for the keep rate than most sellers expect, often more than shaving a little off supplier cost.

The plan choice matters as much as volume. The same scaled store on a Basic Store would pay $875.00 in insertion fees on the 3,500 listings above its allowance, and with no Store at all its take-home would drop to $4,274.90. Treat these as worked examples with stated assumptions, not typical results. Your category rate, supplier cost and order value move every line.

Working backwards from a take-home target

Run the calculator in reverse and it becomes a planning tool. Start with what you want to keep, divide by the keep rate, and you have the gross sales the store has to produce.

Take a $2,000 monthly take-home target at the full-time store's 22.7% keep rate. That needs about $8,807 in gross sales. At a $34 average order value, that is about 259 orders a month, or between eight and nine a day, every day.

Then comes the number that stops most plans: how many listings produce 259 orders? It depends on your sell-through rate. As an illustration, if 3% of your listings sell each month, 259 orders needs about 8,600 active listings. At 5%, it needs about 5,200. A catalog that size also moves you into a higher Store tier, so re-run the Store math at the new count. The gap between "I need nine sales a day" and "I need several thousand live listings" is where most forecasts quietly fall apart.

This is why catalog size, not price tinkering, is the real lever on the take-home line. Pricing still matters, and our eBay pricing strategy guide covers how to price for profit, but no price change turns 1,200 listings into 259 orders a month on its own.

What breaks the calculation once volume climbs

Every line in the model is stable at 40 orders a month and drifts at 600. Four things move.

Supplier cost drift. The 62% cost of goods in the table is a snapshot. Suppliers raise prices and run out of stock without telling you, and a catalog of several thousand items cannot be checked by hand. The cost-of-goods line in your calculator goes stale the week you stop checking.

Margin floor erosion. Repricing to stay competitive at volume lets a few dozen listings drift below cost, and the monthly number quietly shrinks. A repricing rule needs a floor tied to supplier cost, and our breakdown of defending margin with automated repricing covers how to set one.

Promoted listings. Ad spend is a real line the four-line model leaves out by default. As an example, if you pay a 5% ad rate on half your orders, that takes another 2.5% off gross sales. On the full-time store above, that is $127.50 a month, more than a tenth of the take-home. Add it as a fifth line rather than finding it in the payout. Our guide to running profitable Promoted Listings campaigns shows how to set an ad rate your margin can carry.

Dead catalog weight. Listings that never get a view still count against your allowance every month they renew, and they add nothing to the store's sales history. Relevance, price and sales performance are among the signals behind how Cassini ranks listings, so a catalog full of listings nobody clicks does you no favors.

Two habits keep the model honest. Include returns and cancellations at your real rate rather than at zero. And re-run the whole calculation whenever average order value moves by more than a couple of dollars, because that one input moves the keep rate more than anything else. For when the money actually reaches your account, our guide to how eBay payouts work covers the timing.

How to do this in Ecomli: read the four lines instead of rebuilding them

Ecomli publishes this guide, and this section describes our own tool. Ecomli is a non-API browser extension for eBay dropshippers. It works through the eBay seller account already signed in to your desktop Chrome browser, so there is no API connection to authorize, and it sources from Amazon and AliExpress. Here is how it maps onto the calculator.

1. Read your real keep rate. The Overview dashboard shows eBay sales, fees, Promoted Listings costs, refunds, supplier costs and recorded profit by day or period across your whole eBay store, with previous-period comparisons. It syncs the last 90 days of orders, and you can import older eBay CSV reports. Profit is only as complete as the supplier costs recorded.
2. Build the catalog from sales evidence. Product Hunting researches another eBay seller's sold history and matches those products to Amazon or AliExpress, and Create Listings turns picks into eBay listings, up to 10 at a time, priced with your markup. Every plan allows unlimited active listings. What scales is monthly product imports: 1,000 on Starter, 5,000 on Pro and 10,000 on Scale, with +5,000 available for $50 a month. eBay's own selling limits still apply.
3. Keep cost of goods current. Stock Monitoring checks Amazon and AliExpress stock and prices for your Ecomli listings and updates the eBay price and quantity, or ends out-of-stock items, by your rules, including your markup and price-change tolerance. A failed supplier read holds the listing unchanged rather than ending it.
4. Clear dead listings. Auto Pruner (Basic on Pro, Advanced with automatic relisting on Scale) ends zero-view or zero-sale listings in one click by your rules, using fresh Seller Hub reports, so the catalog you pay to renew is the one that sells.

These tasks run in your browser while it is open, and the rules and decisions stay yours. You can see how the pieces fit on the automation overview. If you want your own numbers in one place instead of a spreadsheet, you can create an Ecomli account and connect nothing more than the browser you already sell from.

Frequently asked questions

What is the $600 rule on eBay?

It refers to a planned $600 Form 1099-K reporting threshold from a 2021 federal law change. It was delayed and then reversed: the federal threshold went back to gross payments over $20,000 and more than 200 transactions. eBay's tax reporting page lists that threshold for 2025, and it also applies state reporting thresholds, which can be lower. Whether or not you get a form, income from selling is still taxable, so keep records.

How much will eBay take from a $5,000 sale?

In most categories without a Store, 13.6% of the $5,000 total plus the $0.40 per-order fee, which is $680.40. With a Basic Store or higher, the rate is 12.7% on the first $2,500 and 2.35% on the rest, so the same sale costs $376.65 including the per-order fee. The fee is charged on the total the buyer pays, including shipping and sales tax, and some categories use different rates.

How do you make $10,000 a month on eBay?

Decide first whether you mean sales or take-home, because they are very different stores. $10,000 in sales at a $34 average order value is about 294 orders a month. $10,000 in take-home at the scaled store's 24.1% keep rate needs about $41,528 in sales, which at a $41 average order value is roughly 1,013 orders a month. Neither is a promise. Both depend on catalog size, sell-through, margin and your selling limits, and many sellers never reach either.

What is the 5000 rule on eBay?

It usually refers to a planned $5,000 Form 1099-K threshold for tax year 2024, one step in phasing in the lower threshold. That plan was replaced when the $20,000 and 200-transaction threshold was reinstated. Check eBay's tax reporting page for the threshold that applies to you, including any lower state threshold.

How many sales a month do I need to make $1,000 profit on eBay?

At the full-time store's 22.7% keep rate and a $34 average order value, about 130 orders a month, producing about $4,403 in sales. At a $60 average order value, the same $1,000 needs about 73 orders. Keep rate varies most with category fee rate, Store tier and supplier cost, so run your own numbers.

Does an eBay sales calculator include Promoted Listings fees?

Most don't. They model the final value fee, the per-order fee and sometimes insertion fees, and stop there. If you advertise, multiply your ad rate by the share of orders that come through ads and subtract it from gross sales as a separate line.

Which gross sales figure should I use, item price or total buyer payment?

For revenue, use item price plus shipping charged, because eBay passes the sales tax on. For the fee, use the total buyer payment including sales tax, because that is what eBay charges the final value fee on. Mixing the two up is the most common reason a calculator's output is higher than the payout that lands.

What happens to the model if eBay changes its fees?

Only the constants move. Because the calculator is four visible lines, a change to the final value fee rate, the per-order fee or a Store price is a single substitution, and the keep rate recalculates from there. That is the practical reason to keep the arithmetic visible rather than relying on a tool you can't inspect.
