ROAS by itself does not show profit. This calculator subtracts product cost, marketplace fees, fulfillment, returns, fixed campaign cost and ad spend to show the estimated net result.

How to read it

If the campaign is profitable, compare actual ROAS to break-even ROAS. If profit is negative, improve margin, reduce ad spend, raise conversion rate or change the offer.

Not included

The calculator does not model repeat purchases, organic halo sales or inventory financing unless you add those costs manually.
