Next decision
Use the result to decide whether to test, reprice, or skip.
A product with weak margin before ads usually gets worse after the first test. If the number is close, change the price, reduce the landed cost, or compare it against another product idea.
Formula
Profit is what remains after the boring costs are included.
Simple calculators often stop at price minus product cost. That can make a weak product look alive. Use a fuller contribution margin view before buying inventory or raising the ad budget.
Net profit
Price minus product cost, shipping, packaging, fees, discounts, ad spend, and return reserve.
Profit divided by price
Margin tells you whether the order has enough room for mistakes, refunds, and slower-than-expected ads.
Revenue divided by ad spend
Break-even ROAS shows the ad efficiency needed before the order stops losing money.
