What it measures

Google Ads profit is the true bottom-line return of a campaign after subtracting cost of goods, ad spend, and overhead from revenue.

Formula

Net profit = Revenue − COGS − Ad spend − Overhead · Net margin = Profit ÷ Revenue × 100

Worked example

On $10,000 revenue with $4,000 COGS, $2,500 ad spend, and $800 overhead, net profit is $2,700 — a 27% net margin.

How this calculator works

Net profit = revenue − COGS − ad spend − overhead. Net margin = profit ÷ revenue × 100. Accounting for every cost reveals whether a campaign is truly profitable, not just generating revenue.

Frequently asked questions

Why isn't ROAS enough? +

ROAS ignores product and operating costs. A 4× ROAS can still lose money if your margins are thin. Profit accounts for all costs.

What's a healthy net margin? +

It varies by industry, but a positive and stable net margin after all costs — including ads — is the goal. Many e-commerce brands target 10–20%.

Why can a high ROAS still lose money? +

ROAS ignores product and operating costs. A 4× ROAS on a product with a 70% COGS and high overhead can still produce a negative net profit.

Should I include labor and software in overhead? +

Yes, for a true profit picture. Allocate fulfillment, payment fees, tools, and staff time to overhead so the margin reflects real business economics.

What is contribution margin in advertising? +

It's revenue minus variable costs (COGS, ad spend, fees) per sale — the amount each order contributes toward fixed overhead and profit.
