Questions about the tools
- Are these ad tools free?
- Yes. Every tool on this page is free to use without an account. The Assistant tools have a small daily allowance.
- Do the calculators send my numbers to a server?
- No. The calculators run in your browser. Only the Assistant tools send the text you type, so that a draft can be written.
- Are the results guaranteed?
- No. They are arithmetic on the numbers you enter, or drafts to review. Your own account data and judgement should make the final call.
- Which tool should I start with?
- If you are unsure whether ads can pay off, start with a break-even ROAS or max CPA calculation, then plan a test budget.
- Where do the benchmarks come from?
- We avoid generic benchmarks. Good numbers vary by margin, product and account, and each tool explains how to find your own.
