About the CPM Calculator
Calculates CPM (cost per 1,000 impressions) — the standard pricing metric for display, video, and social advertising — solving for CPM, impressions, or budget depending on which two values you already know.
- Choose what you're solving for: CPM, impressions, or budget.
- Enter the two known values for your chosen mode.
- Read the calculated result alongside the full breakdown.
A $1,000 budget generating 250,000 impressions: a CPM of $4.00. Solving in reverse, that same $4.00 target CPM applied to a $1,000 budget yields the same 250,000 impressions.
CPM (cost per mille) is the standard way display, video, and social advertising is priced. CPM benchmarks vary enormously by platform, targeting, format, industry, and season — there is no single universal 'good' CPM figure.
- • Use 'solve for impressions' when planning a campaign with a fixed budget, to estimate reach before launching.
- • Use 'solve for budget' when you have an impressions goal and need to know what budget achieves it.
- • CPM alone doesn't tell you about engagement or conversions — pair it with CTR and conversion-rate metrics.
