Enter your assumptions to see the projection and the figures behind it.
How this calculator works
Enter the results you want, the rate at which clicks convert, your expected click-through rate and your expected CPM. The calculator works back through clicks and impressions to the budget required.
The formula
Clicks = Results ÷ (Conversion rate ÷ 100). Impressions = Clicks ÷ (CTR ÷ 100). Budget = Impressions ÷ 1,000 × CPM. Cost per result = Budget ÷ Results.
Questions
What CTR should I assume?
Use your own account data. Meta feed click-through rates are typically well under 2%, and vary enormously by creative, audience and placement.
Why does the impression figure look so large?
Because it should. Interruption-based advertising needs far more impressions per result than search, where people are already looking for you.
