Formula

CPM & Impression Solver Formulas

CPM = (Cost / Impressions) × 1,000. Projected Cost = (Target Impressions / 1,000) × CPM.

Calculate CPM from any campaign spend and impression count, then project costs at scale.

Step by step

How the calculation works

1Enter your campaign total impressions and total spend.
2CPM shows your cost per 1,000 impressions — the standard awareness media metric.
3Cost per impression (CPI) is useful for programmatic buying benchmarks.
4The scale projection shows what 1 million impressions would cost at your current CPM.

How to understand and use this calculator

Understanding CPM in digital advertising

CPM — Cost Per Mille (thousand) — is the standard pricing model for brand awareness, display, video, and programmatic advertising. It measures how much you pay per 1,000 ad impressions delivered.

CPM ($) = (Total Campaign Cost ÷ Total Impressions) × 1,000. If you spent $2,500 on a campaign that delivered 500,000 impressions, your CPM = ($2,500 / 500,000) × 1,000 = $5.

CPM campaigns are bought either directly (publisher direct deals at a fixed CPM rate) or via programmatic auctions where CPM fluctuates in real time. Use this calculator alongside your ad CTR and CPC data for complete campaign analysis.

CPM benchmarks by platform and channel

CPM varies enormously by platform and targeting. LinkedIn CPMs range from $30–$90 (premium B2B audience), while Facebook/Meta averages $5–$20 depending on audience and placement. Google Display Network runs $1–$5 CPM. Programmatic open exchange can be $0.50–$3 CPM. Connected TV (CTV) commands $15–$40 CPM.

Premium publisher direct deals (NYT, Bloomberg, etc.) range from $20–$100+ CPM for contextually relevant placements. Podcast advertising is typically priced at $15–$30 CPM. OOH (digital billboard) CPMs can be as low as $3–$10.

For video advertising, non-skippable pre-roll typically costs $10–$30 CPM. Skippable TrueView on YouTube is priced on a CPV (cost per view) basis but converts to an effective CPM once view rates are known.

Scaling impressions from your CPM

Once you know your CPM, you can project cost at scale: Cost = (Target Impressions ÷ 1,000) × CPM. A $5 CPM campaign targeting 1,000,000 impressions costs $5,000. At 10,000,000 impressions: $50,000.

Budget planning for awareness campaigns requires knowing your target reach and frequency. If you want 500,000 unique people to see your ad 3 times on average, that's 1,500,000 impressions. At a $7 CPM, budget = (1,500,000 / 1,000) × $7 = $10,500.

Combine CPM modeling with engagement rate by reach calculations to estimate total engagements from a given impression buy. This converts awareness metrics into engagement projections.

Frequently Asked Questions

What is a good CPM?+

Depends entirely on the channel and objective. For programmatic display, $1–$5 is typical. For Facebook/Meta, $5–$20. For LinkedIn, $30–$90. Lower CPM isn't always better — quality of impressions (audience relevance, viewability, brand safety) matters more.

What is the difference between CPM and eCPM?+

CPM is the advertiser's rate for buying impressions. eCPM (effective CPM) is calculated for publishers: (Total Revenue ÷ Total Impressions) × 1,000. It reflects actual monetization across all ad types and fill rates.

Does CPM guarantee my ad will be seen?+

No. You pay for delivered impressions, not viewable impressions. Viewability rates (where the ad was actually in-view on screen) typically range from 50–75% for display, and 60–80% for video. Look for vCPM (viewable CPM) deals for quality guarantees.

How do I calculate total impressions from a fixed budget?+

Impressions = (Budget ÷ CPM) × 1,000. A $10,000 budget at a $8 CPM delivers 1,250,000 impressions.

What causes CPM to increase over a campaign?+

Audience saturation raises frequency and depletes the available auction supply, pushing CPM higher. Creative fatigue also signals to algorithms that your ad is less engaging, reducing quality scores and raising costs.

Is CPM or CPC better for awareness campaigns?+

CPM is better for awareness because you're paying for eyeballs, not actions. CPC makes more sense for direct response. Hybrid strategies often start with CPM for reach, then retarget with CPC for conversion.

What is a floor CPM in programmatic advertising?+

A floor CPM (or price floor) is the minimum CPM a publisher sets for their inventory in programmatic auctions. Bids below the floor are rejected. Premium publishers set floors at $10–$20+ CPM.

How does ad size affect CPM?+

Larger, more prominent ad units (300×250, 728×90 leaderboard, full-page interstitials) typically command higher CPMs. Smaller formats and less-visible placements are priced lower.

Can I negotiate CPM in direct publisher deals?+

Yes. Direct publisher deals (guaranteed campaigns) are negotiated, and volume commitments typically earn 10–30% discounts vs. list-rate CPMs. Programmatic Private Marketplace (PMP) deals offer a middle ground between open auction and direct.

What is Share of Voice (SOV) related to CPM?+

SOV in programmatic = (Your Impressions ÷ Total Available Impressions) × 100. Buying a dominant SOV in a specific contextual category or on a specific publisher requires calculating the total impression pool and your CPM budget accordingly. See the share of voice calculator.

How does CPM relate to reach and frequency?+

CPM drives both reach (unique users exposed) and frequency (times each user sees the ad). Higher CPM with narrow targeting = more frequency per user. Lower CPM with broad targeting = greater reach. Balance both for effective brand campaigns.

What is the relationship between CPM and CTR?+

CTR directly affects your CPC when buying on a CPM basis: CPC = CPM / (CTR × 10). At a $10 CPM with 2% CTR: CPC = $10 / (2 × 10) = $0.50. Improving CTR on a CPM buy reduces your effective CPC.
