How to tell whether your ads are profitable

ROAS, and what it leaves out

Return on ad spend (ROAS) is revenue ÷ ad spend. A campaign that spent $4,000 and brought in $14,400 has a ROAS of 3.6, often written 3.6× or 360%. Google Ads uses the same idea for target ROAS: $5 in sales for every $1 of ad spend is a 500% target.

ROAS counts revenue, not profit. It ignores what your products cost to make and deliver, so a ROAS that looks healthy can still lose money.

Break-even comes from your margin

Gross margin is the share of each sale left after the cost of making and delivering it. At a 55% margin, each $1 of revenue leaves 55 cents to pay for ads, so ads break even at about $1.82 of revenue per $1 spent. Below that they lose money; above it they add profit.

  • Break-even ROAS = 1 ÷ gross margin.
  • Break-even cost per order (CPA) = average order value × gross margin. It’s the most you can pay to win one order.
  • Profit after ad spend = revenue × gross margin − ad spend.
  • Target ROAS for a profit goal = 1 ÷ (gross margin − the profit margin you want). At a 55% margin and a 15% goal, aim for 2.5×.

ROAS vs ROI

ROI on ad spend divides the profit by what the ads cost, so it shows what you earned beyond getting your money back. In the example, $3,920 of profit on $4,000 of ad spend is a 98% ROI, while the ROAS is 3.6×. ROAS is handy for steering campaigns day to day; ROI tells you whether they were worth it.

Fees, and which numbers to use

Fees charged on your ad spend, such as an agency’s percentage, raise what each ad dollar really costs. Fees charged on each sale, such as payment processing or marketplace fees, shrink what the sale leaves. Add either kind as a percentage and the calculator accounts for it.

Use the same revenue you report on, and a gross margin after the cost of goods and delivery. Without a margin, you’ll still see ROAS and cost per order, but not break-even or profit.
