Professional online tool to calculate Cost Per Mille (CPM), Cost Per Click (CPC), Click-Through Rate (CTR), and Return on Investment (ROI) for your marketing campaigns.
Calculate the cost per thousand impressions for your advertising campaign.
If you spend $500 on an ad campaign and get 250,000 impressions:
CPM = ($500 / 250,000) × 1,000 = $2.00
This means you pay $2.00 for every 1,000 impressions.
Calculate the cost per click for your advertising campaign.
If you spend $300 on ads and receive 150 clicks:
CPC = $300 / 150 = $2.00
Each click costs you $2.00.
Calculate the click-through rate to measure ad performance.
If your ad receives 500 clicks from 50,000 impressions:
CTR = (500 / 50,000) × 100 = 1%
1% of people who saw your ad clicked on it.
Calculate return on investment for your advertising campaigns.
If you spend $1,000 on ads and generate $3,500 in revenue:
ROI = (($3,500 - $1,000) / $1,000) × 100 = 250%
For every dollar spent, you earned $2.50 in profit.
CPM stands for "Cost Per Mille" (mille is Latin for thousand). It represents the cost an advertiser pays for one thousand impressions or views of their advertisement. CPM is one of the most common pricing models in digital advertising.
The CPM formula is straightforward:
CPM = (Total Cost / Total Impressions) × 1,000
For example, if you spend $100 and receive 25,000 impressions, your CPM is $4.

Lower your CPM and improve campaign efficiency with these strategies:
eCPM (Effective CPM): Revenue per 1,000 impressions, useful for publishers to compare different monetization methods.
vCPM (Viewable CPM): Cost per 1,000 viewable impressions, where an ad must be at least 50% visible for 1+ seconds.
CPV (Cost Per View): Common for video advertising, the cost when a user watches your video ad.
CPA (Cost Per Action): Cost for each desired action (signup, purchase, download).
ROAS (Return on Ad Spend): Revenue generated divided by amount spent on advertising.
Average CPM by industry (approximate ranges):
CPM stands for "Cost Per Mille," where "mille" is Latin for thousand. It represents the cost an advertiser pays for one thousand impressions or views of their advertisement. It's also sometimes called "Cost Per Thousand" (CPT).
The CPM formula is: CPM = (Total Cost / Total Impressions) × 1,000
For example, if you spend $250 on an ad campaign that generates 100,000 impressions: CPM = ($250 / 100,000) × 1,000 = $2.50
A "good" CPM varies by industry, platform, and campaign goals. Generally:
Focus on your ROI rather than just CPM rates. A higher CPM can still be profitable if it drives quality traffic.
CPM (Cost Per Mille): You pay per 1,000 impressions (views), regardless of clicks. Best for brand awareness.
CPC (Cost Per Click): You pay only when someone clicks your ad. Best for direct response and conversion campaigns.
Choose CPM for visibility goals and CPC for engagement or conversion goals.
To lower your CPM:
eCPM (Effective Cost Per Mille) is a metric used by publishers to compare revenue across different pricing models (CPM, CPC, CPA). It calculates how much revenue is earned per 1,000 impressions, regardless of the payment model.
Formula: eCPM = (Total Earnings / Total Impressions) × 1,000
High CPM can result from:
Average CPM by platform (approximate):
Rates vary based on targeting, seasonality, and ad quality.
Use CPM when: Your goal is brand awareness, reach, and visibility. You want to control costs per impression.
Use CPA when: Your goal is conversions (sales, signups, downloads). You want to pay only for completed actions.
CPA typically has higher costs per action but guarantees conversions. CPM is more predictable for budgeting but doesn't guarantee engagement.
These metrics are interconnected:
CPC = CPM / (CTR × 1,000)
Example: If CPM is $5 and CTR is 2%:
CPC = $5 / (0.02 × 1,000) = $0.25 per click
Understanding this relationship helps you choose the right bidding model and optimize costs.
