Break even ROAS for dropshipping explained, with a worked example

You launched your first ads, Ads Manager shows a ROAS of 1.8 on one ad and 2.4 on another, and you have no idea which one is making money. Somebody on Reddit says "aim for 3x", somebody else says 2x is fine, and a third person says ROAS is meaningless.

They are all half right. ROAS on its own tells you nothing. ROAS compared with your break even ROAS tells you everything you need to make a keep or kill decision. This guide gives you the formula, a full worked example with every cost a beginner forgets, and a simple way to read your ad results.

What is break even ROAS?

Break even ROAS (often shortened to BEROAS) is the return on ad spend where your ads pay for themselves and nothing more: profit is zero. Above it you make money on each sale, below it you lose money on each sale.

Two terms first, in plain words:

• ROAS (return on ad spend) is revenue from ads divided by ad spend. Spend $100, get $250 in sales, ROAS is 2.5.
• Profit before ads is what is left from one order after the product, shipping, payment fees, apps and refunds, but before you pay for the ad. This is the money available to buy the customer.

ROAS uses revenue, not profit. That is why the same 2.5 ROAS can be great for one store and a slow bleed for another.

What is the break even ROAS formula?

Break even ROAS = selling price ÷ profit per order before ads. The shortcut version is 1 ÷ your margin before ads, written as a decimal.

So a product with a 40 percent margin before ads breaks even at 1 ÷ 0.40 = 2.5. A product with a 25 percent margin breaks even at 4. The guide from Ship To The Moon uses the same formula on a $39.99 product with $19.45 of non-ad costs and lands at 1.95.

Here is the shortcut as a table you can keep next to Ads Manager:

The lower your break even ROAS, the more room your ads have to be imperfect. A high break even ROAS is a pricing problem before it is an ads problem.

A worked example with every cost

The mistake in most calculators is that they only subtract the product and shipping. Here is a $40 product with the costs real stores pay. Fees are estimates: Shopify card rates vary by plan and country, so check yours on the Shopify pricing page.

Now the math:

1. Profit before ads: $40.00 minus $21.50 = $18.50.
2. Margin before ads: $18.50 ÷ $40.00 = 46 percent.
3. Break even ROAS: $40.00 ÷ $18.50 = 2.16.
4. Break even CPA (the most you can pay in ads for one order): $18.50.

If you had only subtracted product and shipping, you would get $40 ÷ $22 = 1.82 and think a 2.0 ROAS was profitable. It is not. That gap of 0.34 is where a lot of beginner stores quietly lose money.

Tip: Do this sum once per product and write it in your product notes. You will look at it every day during testing.

A real example from r/dropshipping

One seller on r/dropshipping asked exactly this: they sell at $149 with about $60 profit per sale and wanted to know which ROAS breaks even. The top reply did the sum: 149 ÷ 60 is about 2.48, so roughly 2.5 to break even, and at least 3.0 to have a real margin.

Another reply added the part people skip: you also have to factor in return rates, payment processing fees, chargebacks and other business expenses. If the $60 did not already include those, the true break even is higher than 2.48.

And a third commenter took the skeptic line that ROAS is meaningless because it ignores cost of goods and overhead. That is true of raw ROAS. It is exactly why you calculate the break even number instead of chasing a benchmark.

What ROAS should you target to actually make a profit?

Break even is the floor, not the goal. Target ROAS = price ÷ (profit before ads minus the profit you want to keep).

Using the $40 example with $18.50 before ads:

This is why "what is a good ROAS" has no single answer. An agency owner on r/ecommerce said they had one client hitting 25x who needed 13x to break even, and others who were happy at 2x. Their rough average after testing was 3 to 4x. Your target comes from your own table, not theirs.

Watch out: Fixed costs like the Shopify subscription, your domain and the money spent testing products that failed are not in the per-order number. Your monthly profit has to cover them too, so scaled ads should sit above break even, not on it.

How do you read ad results with break even ROAS?

Compare each ad's ROAS (or cost per purchase) with your break even line, after the ad has spent enough to judge. Here are three ads on the $40 product, each judged on its own numbers:

Ad B is the only one making money, even though 2.67 does not sound impressive. Ad A looks "almost there" but loses $11.50 on every sale.

A simple decision routine:

1. Let the ad spend enough to judge. One $200k spender in the pack's research waits until an ad has spent about 2 times the order value before deciding. On a $40 product that is $80.
2. Kill clear losers. A rule shared on r/dropshipping: after about $100 of spend with no sale and an add-to-cart rate under 6 percent, kill the product.
3. Hold ads near break even for a few more days if add-to-carts are healthy. Testing ads often start below target and improve.
4. Scale ads above target ROAS slowly, by duplicating rather than doubling budgets.
5. Check the whole store weekly: total Shopify revenue divided by total ad spend across every platform (blended ROAS). If that number is under break even, the store is losing money no matter what single ads say.

The AI Dropshipping pack turns this into a written kill rule sheet you fill in per product before you launch, so you are not deciding with your emotions at midnight.

Why your real break even is higher than you think

Even with the formula right, the reported ROAS can lie. Three things push your true break even up:

• Attribution. Meta and TikTok count a sale if someone clicked or viewed within their window. Shopify may show fewer sales than Ads Manager. Trust the store revenue.
• Placements and countries. A long-time media buyer on r/FacebookAds points out that one placement or one country can drag a blended ROAS down while the ad itself is fine. Break results down before you kill or reshoot.
• Refunds and chargebacks land weeks later. A week that looked like 2.5 ROAS can become 2.1 once returns come in. That is why the refund allowance belongs in the formula.

If you are deciding between platforms, TikTok ads vs Facebook ads for dropshipping covers how costs differ.

Mistakes beginners make with break even ROAS

These come up again and again in r/dropshipping and r/FacebookAds threads:

• Leaving out fees and refunds. The most common one. It makes a losing ad look profitable.
• Using one break even number for the whole store. Each product has its own margin. A $25 gadget and a $60 bundle can have break evens of 3.5 and 1.9.
• Judging after $10 of spend. One or two sales either way swing ROAS wildly. Wait for the spend threshold.
• Chasing a benchmark. "3x is good" means nothing if your break even is 3.2.
• Pricing too low to ever win. If your margin before ads is under 30 percent, your break even is above 3.3 and almost every test will lose. Raise the price, bundle, or find a cheaper supplier before you buy more ads.
• Forgetting fixed costs and failed tests. Per-order break even does not pay for the subscription or the three products that did not work.

How to raise your margin so break even drops

Lowering break even ROAS is usually easier than raising actual ROAS. Every move below lowers the number you have to beat:

• Raise the price by a few dollars and test. On the $40 product, a $45 price with the same costs gives $23.20 before ads (fees and the refund allowance rise slightly), so break even drops to about 1.94.
• Bundle two units with free shipping. Shipping per unit falls and average order value rises.
• Negotiate with your supplier once you have steady orders, or compare agents.
• Cut apps you do not need. $30 a month in apps across 40 orders is $0.75 per order.

Budget planning for all of this is in how much money to start dropshipping.

Where to go from here

1. List every cost per order for your product, including fees, a 3 percent refund allowance and apps.
2. Work out profit before ads, then break even ROAS (price ÷ profit) and break even CPA.
3. Pick the profit you want per order and calculate your target ROAS.
4. Write your kill rule before launching: spend threshold, add-to-cart floor, and the ROAS line.
5. Check blended ROAS against break even every week.
