Break-even is 2.22× at 45.00% gross margin. You are earning $336.00 in contribution — a 8.00% return on ad spend. That is thin: a 7.41% fall in ROAS erases it.

Cost per acquisition and ROAS are the same measurement from two directions: ROAS = AOV ÷ CPA. The stage-by-stage funnel that produces both lives in the Cost Per Acquisition Calculator.

No industry benchmark table here

No industry ROAS benchmark table ships with this tool. Published “average ROAS” figures vary by an order of magnitude across industry, price point, attribution setting and platform, and none could be verified against a current, dated source. A fabricated benchmark is worse than none, because people read benchmarks as targets. The break-even table below is derived arithmetic — it cannot be wrong, and it is the number that actually decides whether a campaign pays.

Blended ROAS is Σrevenue ÷ Σspend, never the average of the ROAS column — an unweighted mean lets a $40.00 test row swing the answer as hard as a $40,000.00 row. Rows with no revenue are listed and excluded from the ranking, but their spend still counts toward the blend, which is correct and surprises people. A row can beat the blend and still lose money.

Return on Ad Spend Calculator – A Revenue Ratio Read as a Profit Verdict

ROAS — return on ad spend — is the revenue an ad produced divided by what it cost: revenue ÷ ad spend, quoted either as a multiple (2.4×) or a percentage (240%). It is the most-quoted number in paid social and the most-misread one, because a revenue ratio keeps getting used as a profit verdict. This ROAS calculator does the division, then does the three things the division hides.

The return on ad spend formula

The identity rearranges three ways, and bridges to cost per acquisition:

ROAS = revenue ÷ ad spend
revenue = ROAS × ad spend
ad spend = revenue ÷ ROAS
ROAS = AOV ÷ CPA — and, decomposed all the way down, ROAS = 1000 × CTR × CVR × AOV ÷ CPM

Spend $4,200, attribute $10,080 of revenue, and the answer is 2.40×. Every dollar came back as $2.40. That is where most reports stop, and it is where the interesting part starts.

Break-even ROAS beats any benchmark

The only number that judges a ROAS is break-even ROAS = 1 ÷ gross margin. At 45% gross margin you must clear 2.22× before the campaign earns a cent; at 25% margin you need 4.00×, so a 3× return that reads beautifully in a deck is quietly losing money. The same relationship stated as profit is cleaner still: POAS = ROAS × gross margin, and a POAS of 1.08× means each ad dollar returned $1.08 of gross profit.

Run the example through it. Gross profit is $10,080 × 0.45 = $4,536; contribution is $4,536 − $4,200 = $336; the return is 8%, not 140%. A 2.40× ROAS turns out to be a thin 8% — a 7% fall in ROAS erases it entirely.

Gross margin, not markup

A product bought for $69 and sold for $100 carries a 45% markup but a 31% gross margin. Feed the markup in and break-even ROAS reads 2.22× when the true figure is 3.23× — a target 30–50% too generous. Use revenue minus cost of goods, divided by revenue.

Net ROAS: what the ad platform never shows

Between the revenue a platform reports and the money that reaches the bank sit refunds, discount codes, absorbed shipping and payment processing. None of them appear in the dashboard. net revenue = revenue × (1 − return rate) − discounts − shipping − fees. An 8% return rate alone takes the example to $10,080 × 0.92 = $9,273.60, so net ROAS is 2.21× — below the 2.22× break-even, and the campaign reported as profitable actually lost $26.88. Nothing about the ads changed. Only the accounting became honest.

Average ROAS and incremental ROAS are different numbers

iROAS = (revenue₂ − revenue₁) ÷ (spend₂ − spend₁) prices the extra money rather than all of it. Take spend from $4,200 to $8,400 and revenue from $10,080 to $16,800: the blended figure is a comfortable 2.00×, but the additional $4,200 came back at 1.60× — well under break-even. Platforms deliver the cheapest conversions first, so the incremental figure is almost always the worse one, and it is the number that should govern a decision to scale. The dashboard stays green while the scale-up loses money.

ROAS, loaded ROAS, blended ROAS and MER

Four different denominators get called “ROAS”. Media-only divides by ad spend. Loaded ROAS adds creator fees, agency retainers, tooling and production. Blended ROAS divides all revenue — including organic — by media spend, and MER divides it by total marketing spend. Show them together and label each, because their break-evens are not the same: blended ROAS and MER include revenue the ads did not buy, so 1 ÷ margin does not apply to them and they belong on a trend line rather than against a threshold.

Why the platform disagrees with finance

Returns, discounts, payment fees, view-through attribution and returning customers who would have bought anyway all inflate attributed revenue. Carry the attribution window into every report, watch for conversion lag on recent spend, and treat incremental ROAS as the honest read.

Using the calculator

Enter spend and revenue — or conversions and average order value, which give an identical answer — and add your gross margin to unlock the verdict, the break-even dial and the revenue-to-profit waterfall. The optional deductions produce a net figure beside the gross one, the two-period panel produces incremental ROAS, and the goal-seek mode turns a target ROAS into the CPA ceiling you paste into a bid cap: CPA ceiling = AOV ÷ target ROAS. Everything runs in the browser and no figure is sent anywhere.

How does this return on ad spend calculator work?

ROAS is one division: return on ad spend = attributed revenue ÷ ad spend. Enter $10,080 of revenue from $4,200 of spend and the tool prints 2.40× — the same number as 240%, and the toggle switches between the two units. Revenue can be entered directly or as conversions × average order value, and both routes give the identical answer. Add your gross margin and it stops being a bare ratio: the tool computes break-even ROAS, the profit in currency, and whether the campaign actually pays.

What is a good ROAS?

The only honest answer is 1 ÷ your gross margin, because that is where the ads start earning rather than costing. At 45% margin break-even is 2.22×; at 25% margin it is 4.00×, so a 3× ROAS that looks strong in a report is losing money on a 25%-margin product. Published industry averages are not a substitute — they vary by an order of magnitude across category, price point, platform and attribution window, and people read them as targets. Judge the number against your own break-even and ignore the benchmark.

What is the difference between ROAS and ROI?

ROAS divides revenue by ad spend; ROI divides profit by total cost. They answer different questions and routinely disagree in sign. A 2.40× ROAS at 45% gross margin produces $4,536 of gross profit on $4,200 of spend — a contribution of $336, which is an 8% return, not a 140% one. Add creator fees, agency retainers, tooling and the people running the campaign and the ROI falls further while the ROAS does not move at all. This tool shows the media-only ratio and a fully-loaded one side by side, and never folds fees silently into the headline.

Why is the ad platform's ROAS higher than the one my bank agrees with?

Five reasons, and usually several at once. Returns and refunds take back revenue the platform already counted; discount codes and shipping you absorb never reach the bank; payment processing takes a slice of every order; view-through attribution credits an ad that was shown but never clicked; and returning customers get attributed to ads for orders they would have placed anyway. An 8% return rate alone drops a 2.40× campaign to 2.21×, which is below a 2.22× break-even — the same campaign, reported as profitable, actually losing money. Enter your return rate, discounts, shipping and fees and the tool shows the net figure beside the gross one.

What is incremental ROAS and why is it worse than my average?

Incremental ROAS prices the extra money: (revenue₂ − revenue₁) ÷ (spend₂ − spend₁) across two periods. Average ROAS prices every dollar you have ever spent. Because platforms deliver the cheapest available conversions first, the incremental figure is almost always the worse of the two. Doubling from $4,200 to $8,400 while revenue goes $10,080 to $16,800 reads as a healthy 2.00× blended, but the extra $4,200 came back at 1.60× — below break-even. That is the number that should govern a decision to scale, and the dashboard will stay green while it happens.

Does gross margin mean the same thing as markup?

No, and confusing them makes every ROAS target 30–50% too generous. Gross margin is profit as a share of the selling price; markup is profit as a share of the cost. A product bought for $69 and sold for $100 carries a 45% markup but a 31% gross margin, and break-even ROAS moves from 2.22× to 3.23× accordingly. This tool asks for gross margin — revenue minus cost of goods, divided by revenue — so check which one your figure is before trusting the verdict.
