# TikTok CPM: Cost Per 1,000 Impressions

> Track how much you pay for every 1,000 TikTok ad impressions. Lower CPM means cheaper reach to your target audience.

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

## 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.

## When to Use

| Scenario                             | Action                                                                              |
| ------------------------------------ | ----------------------------------------------------------------------------------- |
| Comparing reach efficiency           | Lower CPM means you're reaching more people for the same budget                     |
| Evaluating audience targeting        | Narrow audiences often have higher CPMs — assess if the precision is worth the cost |
| Seasonal budget planning             | CPMs rise during peak seasons (holidays, events) — plan accordingly                 |
| Benchmarking against other platforms | Compare TikTok CPM to Meta or Google to allocate budget efficiently                 |
