Frequently asked questions
What is a good ROAS for paid advertising?
A ROAS of 4:1 (earning $4 for every $1 spent) is a common benchmark, but it depends heavily on your gross margin. High-margin products can be profitable at 2–3x ROAS; low-margin products may need 6–10x to break even.
How is CAC different from CPL?
CPL (Cost Per Lead) measures the cost to generate a lead. CAC (Customer Acquisition Cost) measures the cost to convert a lead into a paying customer. Both matter — a low CPL with low conversion still produces high CAC.
Can I use these calculators to report to clients?
Yes, as planning and illustration tools. For formal client reporting, supplement with actual analytics platform data from Google Ads, Meta, or your CRM.
Are these marketing calculators free?
Yes. All CalcBix marketing calculators are free, require no account, and work in any browser.
