How to Use the ROAS Break-Even Calculator

The ROAS break-even calculator shows two things at once: what ad return is enough for a campaign to break even, and what return you need to hit a set profit target. All you need to do is fill in two fields.

Gross margin % — the percentage of the selling price left after direct costs. The default is 45.
Profit target % — the share of the selling price you want to keep as profit. The default is 15.
Read the results: break-even ROAS and the ROAS needed for your profit target.

You can change the default values freely and immediately see how the required ad return changes. The calculations run in your browser, based on the numbers you enter.

For a 45% gross margin and a 15% profit target, you'll see 2.22x and 3.33x. The first number means every dollar spent on ads must come back as $2.22 in revenue for the campaign not to lose money. The second means that at $3.33 in revenue per $1 of ad spend, you keep the 15% profit target.

How to Set Gross Margin and Profit Target

Gross margin is the part of the selling price that remains after subtracting the costs directly tied to selling one unit. You calculate it like this: gross margin % = (selling price − direct costs) ÷ selling price × 100%.

the cost of buying or making the product,
packaging and shipping that you pay for,
the marketplace or payment processor fee,
the cost of handling returns and complaints, if it is recurring,
discounts and promotions that actually lower the price.

If you leave out any of these costs, your margin will come out higher than it really is, and the required ROAS will be lower than you actually need. It is better to calculate conservatively than optimistically.

Profit target is the share of the selling price you want to keep after paying direct costs and advertising. Keep this relationship in mind: the profit target must be lower than the gross margin. At a 45% margin and a 15% target, 30 percentage points of the selling price are left for advertising — if the target equals the margin, nothing is left.

Interpreting Break-Even ROAS and Target ROAS

ROAS is ad revenue divided by ad cost. A ROAS of 2.22x means that every dollar you spend on ads brings in $2.22 in revenue.

Break-even ROAS is the level at which ad revenue covers ad cost and the direct costs of sale, but does not yet produce profit. You calculate it simply: 1 ÷ (gross margin % ÷ 100). At a 45% margin: 1 ÷ 0.45 = 2.22x. Below that level, the campaign adds to your costs; above it, you start to earn.

ROAS needed for a profit target is higher because it must also cover the profit target: 1 ÷ ((gross margin % − profit target %) ÷ 100). At a 45% margin and a 15% target: 1 ÷ 0.30 = 3.33x.

Gross margin	Profit target	Break-even ROAS	ROAS for profit target
45%	15%	2.22x	3.33x

In practice: if a campaign comes back with a ROAS below break-even, it is running at a loss. Between break-even and the profit target, you break even or earn slightly, and only at the target level do you achieve the intended profitability. The higher the gross margin, the lower the ROAS needed to reach the same goal.

How Variable Costs, Fees, and Returns Affect Required ROAS

Required ROAS depends directly on gross margin, so every cost that lowers it raises the bar for your campaigns.

Platform fees. Amazon, Etsy, eBay, Shopify, Vinted, and TikTok charge fees for sales, listings, or payment processing. Rates vary and change, so check the current pricing and enter the real cost in your margin.
Shipping and packaging. Even when the customer pays for delivery, you often pay more on returns or on free shipping over a threshold.
Returns and complaints. Ad revenue does not turn into lasting sales in those cases, and you bear the logistics cost.
Discounts and sales. The price goes down while the purchase cost stays the same.

The simplest approach: calculate your margin after accounting for fees, shipping, and your average return rate, and only then enter it into the calculator. You will then see how much higher the required ROAS is than in a simplified calculation.

Limitations and What the Tool Does Not Calculate

The calculator answers one specific question: what ROAS follows from the gross margin and profit target you enter. The rest depends on your situation.

Taxes — VAT, income tax, and other taxes are not included here.
Fixed costs — rent, subscriptions, salaries, accounting. They do not disappear even when a single campaign breaks even.
Platform fees and payment costs — if you do not include them in your margin, they will not appear in the calculation; check current rates in your platform's pricing.
Returns, discounts, and seasonal swings — the tool works with one average margin that you provide.
Currency exchange rates — the result is a ratio of revenue to ad cost, so it does not include current conversions.
Customer lifetime value and organic sales — ROAS shows only sales attributed to ads.

For that reason, treat the result as a benchmark, not as a final profitability cutoff. With unusual costs, individual commercial terms, or a business where customers return after many months, the real break-even point may look different.

Frequently Asked Questions

How do you calculate break-even ROAS?

Divide 1 by your gross margin expressed as a decimal. At a 45% margin, break-even is 1 ÷ 0.45, or 2.22x. The calculator does this for you after you enter the margin.

What is ROAS and how does it differ from ROI?

ROAS is ad revenue divided by ad cost — it tells you how much sales comes back from every dollar spent on campaigns. ROI relates profit to the costs incurred, so it answers a different question. Break-even ROAS shows when you are not losing money, not when you are earning it.

What is a good ROAS?

It depends on your gross margin. At a 45% margin, break-even is 2.22x, and to reach a 15% profit you need 3.33x. With a lower margin, the required ROAS is higher; with a higher margin, it is lower.

Does the calculator include marketplace fees and shipping costs?

It does not add them automatically — it calculates based on the gross margin and profit target you enter. It is best to add fees, shipping, and your average return rate to your costs, and only then set the margin. Check current rates in your platform's pricing.

What should you do if the profit target equals the gross margin?

That target is unattainable from margin alone, because nothing is left for advertising — the calculator then tells you the target is impossible. Lower the profit target or raise the margin, for example by negotiating the purchase cost or reducing shipping costs.

How can you lower the required ROAS?

Raise your gross margin: negotiate purchase prices, reduce packaging and shipping costs, and work on lowering returns. You can also lower the profit target itself if you want to scale campaigns faster.

Results are indicative and depend on the accuracy of the gross margin and profit target you enter; before deciding, check current costs and platform pricing.
