TikTok CPM: Cost Per 1,000 Impressions

TikTok CPM measures how much you pay for every 1,000 times your ad is shown — lower CPM means cheaper impressions.

Formula

TikTok CPM = TikTok Spend ÷ TikTok Impressions × 1,000

Example

Your TikTok campaign spent $5,000 and delivered 1,250,000 impressions last month.

Metric	Value
TikTok Spend	$5,000
TikTok Impressions	1,250,000
TikTok CPM	$4.00

Calculation: $5,000 ÷ 1,250,000 × 1,000 = $4.00 CPM

How It Works

CPM divides your total ad spend by the number of impressions, then multiplies by 1,000 to express cost per thousand views. TikTok CPM varies by audience competitiveness, ad placement, time of year, and creative quality. Broader targeting typically yields lower CPMs while niche audiences cost more.
