Find the ROAS you need before ads turn a product unprofitable
Formula: Break-even ROAS = Sale price ÷ pre-ad profit. Pre-ad profit is revenue after product cost, fulfillment, and platform fees, before ad spend.

This ROAS tool is for ecommerce sellers, Shopify stores, Amazon sellers, and paid ads operators who need to know how much ad spend a product can absorb before profit turns to zero. Enter sale price, product cost, fulfillment or shipping cost, platform fee percentage, and a target ROAS to calculate pre-ad profit, break-even ROAS, max ad spend, and profit at your target return. Use it before launching Meta ads, Google Shopping, TikTok ads, or marketplace campaigns when searches like Meta ads break-even ROAS or ecommerce ROAS calculator point to the same decision: can this product afford paid traffic? It is especially useful before scaling a winning ad set, testing a new creative, raising budget, or deciding whether a product needs a higher price, lower cost, or larger average order value before paid traffic makes sense.
If a product sells for $50 and has $20 of pre-ad profit, break-even ROAS is 2.50x. Below 2.50x, paid ads lose money before fixed costs.
If your target ROAS is 3.00x on a $50 order, ad spend is about $16.67. With $20 of pre-ad profit, the order keeps about $3.33 after ads.

Break-even ROAS connects product unit economics with advertising. The goal is not just to chase a high ROAS number, but to know the lowest ROAS that keeps the order from losing money.
Start with the price the customer pays for one order. If your average order value is higher than one item, use average order value instead of single-product price.
Enter product cost and the fulfillment, shipping, pick-pack, or delivery cost tied to the order. These costs must be paid before advertising profit is considered. If you offer free shipping, include the seller-paid shipping cost here so the ad budget is judged against real contribution profit.
Use a fee percentage for marketplace fees, payment processing, app fees, or checkout costs. For Amazon, Etsy, eBay, or Shopify, use the closest blended percentage if you do not have exact fees yet. A rough fee estimate is better than ignoring fees entirely.
Pre-ad profit is sale price minus product cost, fulfillment, and fees. This is the maximum amount you can spend on ads before the order breaks even. If this number is already thin, paid traffic will need an unusually strong conversion rate or higher order value.
Break-even ROAS is sale price divided by pre-ad profit. If the result is 2.50x, then ad campaigns below 2.50x lose money before fixed costs, while campaigns above 2.50x leave contribution profit.
Enter the ROAS you expect from Meta, Google, TikTok, or marketplace ads. The calculator shows estimated ad spend and profit at that ROAS so you can decide whether the campaign target is realistic. Run several targets, such as 2x, 3x, and 4x, to see how sensitive profit is to media buying performance.
Break-even ROAS is the return on ad spend where ad profit becomes zero. If a product sells for $50 and has $20 of pre-ad profit, break-even ROAS is $50 ÷ $20 = 2.50x. Below that ROAS, the order loses money after ads.
First calculate pre-ad profit: sale price minus product cost, fulfillment, shipping, and fees. Then divide sale price by pre-ad profit. The calculator also shows the maximum ad spend you can afford before breaking even.
No. Break-even ROAS is the minimum ROAS needed to avoid losing money on the order. Target ROAS should usually be higher because sellers also need profit for fixed costs, returns, overhead, and growth.
Include variable costs tied to the sale: product cost, packaging, fulfillment, shipping, payment fees, marketplace fees, and any other per-order cost. Do not include monthly fixed costs unless you are building a broader break-even model.
Yes. The formula is channel-agnostic. Use it to check the lowest ROAS your Meta, Google Shopping, TikTok, Amazon Ads, or Etsy Ads campaign needs before the order becomes unprofitable.
Revenue does not show how much profit is available for ads. A product with high COGS, shipping, or marketplace fees may need a very high ROAS to break even, while a high-margin product can tolerate more ad spend.
