Frequently asked questions

What does CPM mean?

CPM is “cost per mille” — the cost per one thousand impressions. It’s the most common pricing model for awareness and reach campaigns where impressions, not clicks, are the goal.

CPM vs CPC — which should I use?

Use CPM when your goal is visibility/reach (brand awareness, video views). Use CPC when you’re paying for and measuring traffic. Many campaigns track both.

How do I lower my CPM?

Tighter audience targeting, better creative, broader placements, and choosing less competitive times or networks can all reduce CPM.

How do I calculate CPM (cost per 1,000 impressions)?

Use the CPM formula: divide your total ad spend by impressions and multiply by 1,000. For example, ₹5,000 across 1,00,000 impressions is ₹5,000 ÷ 1,00,000 × 1,000 = ₹50 CPM. This free CPM calculator does it instantly.

What is a good CPM for ads?

A good CPM depends on the platform, audience and ad format — premium audiences and video placements cost more per thousand impressions. Compare your cost per 1,000 impressions against your own campaigns and the reach value you’re getting.

How do I convert CPM to a total ad budget?

Multiply your target impressions by the CPM, then divide by 1,000. For example, to reach 5,00,000 impressions at a ₹50 CPM, you’d budget 5,00,000 ÷ 1,000 × ₹50 = ₹25,000.

What is the difference between CPM and CPC?

CPM (cost per 1,000 impressions) charges for views regardless of clicks, while CPC (cost per click) charges only when someone clicks. Use CPM for brand awareness and reach; use CPC when you're paying for traffic. Many platforms let you buy either way.

How do I work out my total budget from a target CPM?

Multiply your target impressions by the CPM and divide by 1,000. For example, 5,00,000 impressions at a ₹50 CPM is 5,00,000 ÷ 1,000 × 50 = ₹25,000. Enter spend and impressions above to reverse it and find your actual CPM.
