ChatGPT Ads reach & budget calculator

How it works

1. We read your hint. A language model breaks down the audience description: the buyer's industry, where they are in the buying journey, and 3–5 short search phrases that real people would type when they need what you sell.
2. We estimate audience size. Each phrase gets a monthly search range, weighted by how specific the phrase is. Broad phrases get bigger ranges with lower confidence — that's intentional, not a bug.
3. We estimate CPC. Each phrase returns a low/high CPC band. ChatGPT Ads currently sees less auction competition than Google, so planning bands skew cheaper than search — but we keep them honest instead of promising pennies.
4. We size budgets by clicks. Test = enough budget for a 5–10 day read. Validate = 50–100 clicks. Scale = 300+ clicks, where optimization actually starts working. The dollar amounts shrink when CPCs are high and grow when they're low.
5. We flag thin data honestly. If search volume is low or fewer than two phrases return data, the result says so instead of pretending to be precise.
6. Built for booked calls. Once your ads run, connect Your Calendar and every click-through, booking, and paid invoice is attributed back to the campaign — so you know what your cost per booked call really is.
