TikTok CPM & cost-per-engagement calculator

Work out the CPM, CPC, and cost-per-engagement of any TikTok campaign — or reverse it to see how much reach a budget buys. Free and instant, no signup.

Reverse: budget → reach

How it works

  • CPM = spend ÷ impressions × 1,000 — the cost per thousand views.
  • CPE = spend ÷ engagements and CPC = spend ÷ clicks. Lower is more efficient.
  • Use the reverse section to turn a budget into estimated reach at a target CPM.
