Running Meta Ads or Google Ads without knowing your break-even ROAS is like driving without a fuel gauge. The dashboard might show a “3x ROAS,” and you could still be losing money on every order. This free break-even ROAS calculator works out the minimum return on ad spend your campaigns need before they cost you money using your real selling price, product cost, shipping, fees, and profit goals.
Break-even ROAS is your selling price divided by your gross profit per order before ad costs. If a product sells for 40 and you keep 20 after product cost, shipping, and fees, your break-even ROAS is 40 ÷ 20 = 2.0x. Any campaign returning less than 2.0x revenue per unit of ad spend loses money on that product; anything above it contributes profit. Enter your own numbers in the calculator above to get your exact figure.
Enter your product numbers below to find the minimum ROAS your ads need to break even, plus the target ROAS you need to hit your desired profit margin. Pick your currency, then use that same currency for every field — the calculator does not convert exchange rates.
Fields marked optional can be left empty.
Results are estimates based only on the numbers you enter. They do not include taxes or fixed overheads unless you add them to your costs, and they are not financial advice.
ROAS stands for return on ad spend. It measures how much revenue your ads generate for every unit of currency you spend. The standard ROAS formula is simple:
ROAS = revenue from ads ÷ ad spend
The problem is that ROAS only compares revenue to ad spend. It says nothing about whether you actually made a profit, because revenue is not profit. Your product cost, shipping, payment processing fees, and packaging all come out of that revenue before anything reaches you.
Break-even return on ad spend fixes this blind spot. It tells you the exact ROAS at which your ad revenue covers the ad cost and every other cost you entered — the point where you make zero profit and zero loss. It is the floor under your campaigns, not a target to aim for.
One important thing to understand: break-even ROAS depends entirely on your margins. A store with high margins can break even at a low ROAS. A store with thin margins might need a very high ROAS to avoid losses. That is why there is no universal “good ROAS” — the same 2.5x that makes one store profitable can quietly drain another.
Press Calculate ROAS, and the tool returns six numbers plus a plain-English explanation of what they mean for your ads.
Here is exactly what the calculator does, step by step:
Payment fee = selling price × payment fee %
Gross profit before ads = selling price − product cost − shipping − other cost − payment fee
Break even CPA = gross profit before ads (the most you can pay to acquire one customer)
Break even ROAS = selling price ÷ gross profit before ads
Target profit per order = selling price × desired profit margin %
Allowed ad cost per order = gross profit before ads − target profit per order
Target ROAS = selling price ÷ allowed ad cost per order
Actual ROAS = revenue ÷ ad spend
Notice that break-even ROAS and break-even CPA are two views of the same limit. CPA expresses it in currency (“I can pay up to 20 per customer”), while ROAS expresses it as a ratio (“I need 2x back on every unit of spend”). Meta Ads and Google Ads let you optimise toward either, so it helps to know both.
Say you run a Shopify or WooCommerce store selling a kitchen gadget:
Gross profit before ads = 40 − 12 − 4 − 1.50 − 1.16 = 21.34
Break even ROAS = 40 ÷ 21.34 = 1.87x
So any campaign for this product returning less than 1.87x is losing money, even if the ads dashboard makes 1.5x look respectable. Now add a goal: you want to keep 15% of each sale (6.00) as profit. Allowed ad cost per order drops to 21.34 − 6.00 = 15.34, and your target ROAS becomes 40 ÷ 15.34 = 2.61x.
Same product, same ads — but the number you should actually manage toward is 2.61x, not 1.87x, because breaking even is not the goal of a business.
These two get confused constantly, so here is the difference in one line each:
Target ROAS is always higher than break even ROAS, because it reserves part of your margin as profit instead of handing all of it to the ad platform. When you set a target ROAS bid strategy in Google Ads or a ROAS goal in Meta Ads, the number you enter should be your target ROAS — never your break-even ROAS. If you tell the platform to optimise toward break-even, the best outcome it can deliver is a business that earns nothing.
Many advertisers also keep a buffer above break-even to absorb things the calculator cannot see: returns, refunds, attribution errors, and seasonal swings. How large that buffer should be depends on your return rate and how accurate your tracking is — there is no fixed rule.
Both platforms report ROAS prominently, and both let you automate bidding around it. That makes break-even ROAS the single most useful number to know before touching either platform:
One caution: platform-reported ROAS depends on attribution settings. A 7-day click window and a 1-day click window can report very different revenue for the same campaign. Compare like with like, and double-check platform numbers against your store’s actual orders.
ROAS is a ratio of revenue to ad spend — nothing more. Four things it does not tell you:
Equally, a lower ROAS does not always mean bad performance — a deliberately aggressive launch campaign, or a campaign feeding a strong repeat-purchase product, can run near break-even by design. The point of this calculator is to make that a decision, not an accident.
It is a tool that works out the minimum return on ad spend your campaigns need so ad revenue covers your ad costs and all your per-order costs — product, shipping, fees, and anything else you include. Below that number you lose money on each ad-driven order; above it you make some profit.
Divide your selling price by your gross profit before ads. Gross profit before ads is your selling price minus product cost, shipping, payment fees, and other per-order costs. Example: price 50, total costs 30, profit 20 → break even ROAS = 50 ÷ 20 = 2.5x.
There is no universal number, and be wary of anyone quoting one. A lower break even ROAS is generally easier to live with because it means your margins are doing more of the work — but whether any given figure is workable depends on what ROAS your ads can realistically achieve in your niche and at your budget.
ROAS measures what your ads actually returned (revenue ÷ spend). Break even ROAS measures what they needed to return to avoid a loss. The first is a performance reading; the second is a threshold. Comparing the two tells you whether a campaign made or lost money on the orders it drove.
A high break even ROAS almost always means a thin margin. If your product cost, shipping, and fees eat most of the selling price, only a small slice is left to pay for ads, so the required ROAS climbs. Fixes include raising the price, negotiating product or shipping costs down, reducing fees, or increasing average order value with bundles — anything that widens the gap between price and cost.
Yes. The maths is platform-independent. Use your break even and target ROAS to judge campaigns in Meta Ads Manager and to set ROAS goals for Advantage+ or manual campaigns. Just remember Meta’s reported revenue depends on its attribution window.
Yes. It works the same way as a Google Ads ROAS calculator: use the target ROAS output when setting up target ROAS Smart Bidding, and use the break even figure as your floor when reviewing campaign performance in Google Ads reports.
Target ROAS is the return on ad spend you need to hit a chosen profit margin, not just to break even. This calculator works it out by reserving your desired profit per order first, then dividing selling price by whatever margin remains for ads. It is also the name of a Google Ads bidding strategy that optimises toward a ROAS number you provide — which should be this figure.
Both, for different jobs. ROAS is fast feedback for managing campaigns day to day. Profit is the truth about whether the business works. The healthiest habit is using ROAS against your break even and target thresholds for campaign decisions, and reviewing actual profit — including returns, refunds, and overheads — at the business level.
No. Standard ROAS is only revenue divided by ad spend. Product cost is invisible to it, which is exactly why a “good” ROAS can hide a loss. Break even ROAS exists to bring product cost and other order costs into the picture.
No, not by default. Shipping you pay for reduces your real profit but does not appear anywhere in the standard ROAS formula. This calculator includes a dedicated shipping field so your break even reflects it.
Widen your per-order margin. In practice: raise your selling price if the market allows, reduce product cost with suppliers, charge for or reduce shipping, cut packaging and fulfilment costs, review payment fees, and lift average order value with bundles or add-ons. Every unit of margin you recover lowers the ROAS your ads must achieve.
ROAS tells you what your ads returned. Break-even ROAS tells you what that return had to be before it meant anything. Once you know your break-even and target numbers, every figure in Meta Ads Manager or Google Ads finally has context — you can spot the campaigns that look good but leak money, and the ones that look ordinary but quietly earn.
