How do you calculate CPM?

CPM (cost per mille) is calculated by dividing your total ad spend by the number of impressions, then multiplying by 1,000. Formula: CPM = (Total Cost ÷ Impressions) × 1,000.

What is a good CPM for Meta Ads in 2026?

A 'good' CPM depends on geography, audience, vertical and creative quality. For broad audiences in the US/EU, $5 to $15 is typical for Meta. In South Asia (Bangladesh, India), CPMs often run $0.80 to $3. Lower CPM is not always better, it usually correlates with cheaper audiences and lower buying intent.

How do I lower my CPM?

Improve creative thumb-stopping power, refresh ads before fatigue sets in, broaden audiences when CPM spikes, switch to lower-cost placements (Reels, Audience Network), and improve relevance and quality scores.

How to calculate CPM

CPM stands for cost per milleLatin for "per thousand." It's the cost an advertiser pays for 1,000 ad impressions. To calculate CPM manually, divide your total ad spend by the number of impressions delivered, then multiply by 1,000.

CPM = (Total Spend ÷ Impressions) × 1,000

Example:
 Spend = $1,000
 Impressions = 250,000
 CPM = (1000 / 250000) × 1000 = $4.00
