CPM Calculator

1. Choose what to solve for — CPM (most common), total campaign cost, or required impressions to hit a goal.
2. Enter your two known values. Cost is what you paid (or plan to pay). Impressions is the total number of ad views. CPM is dollars per 1,000 impressions.
3. The result appears instantly with cost-per-impression and a benchmark table showing where your CPM sits versus typical rates by channel.
4. Compare your CPM to the benchmark table. If your CPM is significantly above the channel average, your targeting may be too narrow or your creative isn't engaging. Below average usually means good audience-creative fit.

CPM stands for Cost Per Mille — Latin for "cost per thousand." It's the standard pricing model for display, video, and out-of-home advertising where the goal is reach or brand awareness rather than direct response.

CPM = (Total Cost / Total Impressions) × 1,000

Cost = (CPM × Impressions) / 1,000
Impressions = (Cost / CPM) × 1,000

Example: Spending $500 on a Facebook campaign that delivered 100,000 impressions yields CPM = (500 / 100,000) × 1,000 = $5.00 CPM. That's right in the typical Facebook range. The same $500 on LinkedIn might only deliver 10,000 impressions, giving a $50 CPM — much higher, because LinkedIn audiences are professional and reach is harder to buy.

A "good" CPM is entirely channel-relative. A $30 CPM on LinkedIn is great. A $30 CPM on Google Display is terrible. The benchmark table above gives the typical range for each channel — your goal is to land at or below the midpoint of your target channel.

Three factors push CPM up or down:

If CPM is your primary KPI, you're probably running a brand awareness campaign. If you care about clicks or conversions, CPM is a secondary metric — a high CPM is fine if it converts at a low CPA. Run the math both ways before optimizing for either alone.
