Use only ad-attributed revenue, not total store revenue, or you inflate the number. Break-even ROAS equals 1 divided by your profit margin, so a 50% margin breaks even at 2.0x and a 25% margin needs 4.0x just to cover costs.

The honest numerator is only the revenue the ad platform (or your own attribution) can tie back to an ad.

If $1,000 of ad spend produces $4,000 in tracked sales, your ROAS is 4,000 divided by 1,000, which is 4.0x, also written as 4:1 or 400%. The only judgement call is the inputs: use the revenue the ads can actually be credited with, not your whole store's revenue, and decide whether your spend figure is media-only or includes production and fees.",{"question":536,"answer":537},"What is the ROAS formula as a percentage versus a ratio?","They are the same number in different notations. The multiple form is the raw division (4.0x). The ratio form reads that as a relationship (4:1). The percentage form multiplies the division by 100, so 4.0x becomes 400%. A 400% ROAS is not 400 times your money, it is 4.0x written as a percentage, so divide any percentage by 100 to read it as a multiple. Pick one notation for your own reporting and convert everything you read into it.",{"question":539,"answer":540},"How do I calculate break-even ROAS?","Break-even ROAS equals 1 divided by your profit margin. The logic: at break-even, your margin times revenue equals your ad spend, so revenue divided by spend equals 1 divided by margin. A 50% margin breaks even at 2.0x, a 40% margin at 2.5x, a 25% margin at 4.0x, and a 20% margin at 5.0x. Calculate the margin after the cost of goods, shipping, fees, returns, and discounts, or the bar comes out too low.",{"question":542,"answer":543},"What is the difference between ROAS and POAS?","ROAS divides revenue by ad spend, so it measures top-line return. POAS, profit on ad spend, divides profit by ad spend, where profit is revenue minus the cost of goods, shipping, returns, payment fees, and discounts. A POAS above 1.0x means the campaign made money after fulfilling the order, which a high ROAS alone cannot tell you. On a thin-margin product a 4.0x ROAS can sit at a POAS below 1.0x, meaning it lost money.",{"question":545,"answer":546},"What is the difference between ROAS and MER?","ROAS is per-campaign and attribution-dependent: it credits a specific ad with a specific slice of revenue. MER, the marketing efficiency ratio, is total business revenue divided by total marketing spend across every channel, with no attribution at all. It is the blended, account-level view of whether marketing as a whole is paying for itself. MER is the sanity check that survives the attribution chaos ROAS suffers, because it only compares money in to money out at the account level.",{"question":548,"answer":549},"What is the difference between ROAS and ROI?","ROAS uses top-line revenue, while ROI subtracts every cost, including the cost of goods and the ad spend itself, and reports what is left. ROAS is practically identical to ROI, just narrowed to advertising spend rather than a business expenditure in general, so it is the faster, narrower cousin. The practical upshot is that a strong ROAS can still be a negative ROI on a thin-margin product, so use ROAS to compare campaigns and ROI or POAS to confirm one actually made money.",{"question":551,"answer":552},"What revenue do I use when calculating ROAS, total sales or ad-attributed sales?","Only the revenue attributed to the ads. Using total store revenue inflates ROAS because it credits your ads with sales from email, organic search, and repeat customers that the ads never touched. There is a further wrinkle: the same orders produce different ROAS in different platforms because each one attributes with its own window and matching logic, and summing every platform's claimed revenue overshoots what your store actually banked. Pick one source of truth and stay on it.",{"question":554,"answer":555},"How do I work out the ad spend or revenue I need to hit a target ROAS?","Rearrange the formula. Required revenue equals your target ROAS times your planned spend, so a 3.0x target on $5,000 of spend needs $15,000 in attributed sales. Maximum spend equals your projected revenue divided by your target ROAS, so $30,000 in expected sales at a 2.5x minimum target means spending no more than $12,000. This turns ROAS from a grade you receive into a budget you plan.","\u002Fimages\u002Fblog\u002Fhow-to-calculate-roas-hero.webp","You spent $1,000, the dashboard shows a ROAS, and a source you trust writes it as a percentage while a teammate says it as a multiple, so now you are not even sure the numbers agree.
