What is break even ROAS?

Break even ROAS is the return on ad spend where you make exactly zero profit. Spend above it and you are earning, spend below it and you are paying for sales. This break even ROAS calculator works the number out from your product economics: price, cost of goods, shipping, fees, and anything else that comes out of an order.

Most people running ads never do this math, and it is why so many accounts feel confusing. Without a break even number, a 2.5x return is just a number. With one, it is either a green light or a leak. It also gives you a target ROAS to set in the ad platform, and a hard ceiling on what you can pay for a customer.

The number matters most when margins are tight. Break even ROAS for dropshipping is usually high, often 3x or more, because product cost plus slow shipping plus fees can eat two thirds of the order. Brands that manufacture their own product, or sell digital goods, sit far lower and can outbid a dropshipper for the same click all day.

The formula, with a worked example

It runs in two steps.

Gross profit per order = price - cost of goods - shipping - other costs - (price x fee %) Break even ROAS = price / gross profit per order

Use the defaults above. You sell for $100. Product costs $30, shipping and fulfillment cost $10, payment and platform fees take 5% or $5, and another $5 goes to packaging, returns, and the occasional support ticket. Add those up and $50 is gone, leaving $50 of gross profit.

Break even ROAS is $100 divided by $50, which is 2.0x. Your gross margin is 50%, and your maximum cost per acquisition is $50, because that is the entire profit sitting inside one order.

Read the max CPA line as the more useful of the two. ROAS is a ratio and gets abstract fast. A $50 ceiling on what you pay for a customer is something you can check against the cost per purchase in your ads manager this afternoon.

Setting a target ROAS above break even

Break even is the floor, not the goal. Overhead, the ads you tested and killed, software, and your own time all sit outside this math, so set a target ROAS above break even rather than at it. A common approach is to add 30% to 50% on top. If you break even at 2x, target 2.6x to 3x, and treat anything under 2x as a campaign to fix or turn off.

Where brands land varies a lot by model. Private label products with 60% to 80% margins often break even somewhere near 1.3x to 1.7x. Standard ecommerce with 40% to 50% margins sits closer to 2x to 2.5x. Dropshipping with 25% to 35% margins can need 3x or more, which is why so many dropshipping stores struggle on paid traffic without an upsell or a subscription attached.

To lower your break even ROAS, attack the costs inside the formula. Raising price is the fastest lever and the one people avoid. Renegotiating unit cost at higher volume is next. Free shipping thresholds, lighter packaging, and better chargeback handling all move the number. Adding a post purchase upsell or a second product to the cart raises effective order value, which lowers break even ROAS across the whole account even when the front end product never changes.
