What is the PPC ROI Calculator?

See whether your paid search campaigns make money before you spend it. Enter your monthly ad budget, average cost per click, website conversion rate, lead-to-customer close rate, average sale value and gross margin. The calculator shows clicks, leads, customers, revenue, gross profit, ROAS, ROI, cost per lead and cost per customer.

It also calculates your break-even cost per click and break-even ROAS — the most you can pay before advertising stops being profitable — and a scenario table showing how improving conversion rate or CPC changes profit.

ROAS versus ROI

ROAS (return on ad spend) is revenue divided by ad spend. A ROAS of 4 means $4 of revenue for every $1 of advertising. ROI subtracts all costs, including the cost of delivering the product or service, so it shows real profit. A campaign with a 3× ROAS can still lose money if your margin is 25%. That is why this calculator asks for your gross margin.

Break-even CPC: the number every advertiser should know

Break-even CPC = average sale value × gross margin × close rate × conversion rate. If your average click costs more than this, every click loses money. Knowing it lets you set sensible bid limits and target CPA or ROAS goals for Smart Bidding.
