Use our CPC and CPM calculator to estimate campaign costs, compare pricing models, and plan newsletter advertising budgets with more confidence.
Use this calculator to compare CPC, CPM, clicks, impressions, and click-through rate so you can better understand the cost of a digital media campaign.
CPC and CPM are two of the most common pricing models in online advertising.
CPC, or cost per click, means you pay based on the number of clicks your campaign receives.
CPM, or cost per thousand impressions, means you pay based on how many times your ad is shown.
For example, if a campaign delivers 10,000 impressions at a $2 CPM, the total cost would be $20. If a campaign runs at a $1.50 CPC, you would pay $1.50 for each click generated.
The connection between CPC and CPM depends on CTR, or click-through rate.
CTR shows how often people click after seeing an ad. Once you know your impressions, clicks, CPC, or CPM, you can estimate the rest of the campaign performance more easily.
CPC stands for cost per click.
The formula is:
CPC = Total Cost / Number of Clicks
You can also estimate CPC using CPM and CTR: CPC = CPM / (10 × CTR)
For example, if your CPM is $20 and your CTR is 2%, your estimated CPC would be: $20 / 20 = $1.00 CPC
CPM stands for cost per thousand impressions.
The formula is: CPM = (Total Cost / Impressions) × 1,000
For example, if you spend $500 and receive 100,000 impressions, your CPM would be: ($500 / 100,000) × 1,000 = $5 CPM
CTR stands for click-through rate.
It shows the percentage of impressions that turned into clicks.
The formula is: CTR = (Clicks / Impressions) × 100
For example, if your campaign receives 1,000 clicks from 100,000 impressions, your CTR would be: 1%
CPC vs. CPM
CPC pricing is often used when the goal is to drive traffic, visits, or measurable actions.
CPM pricing is often used when the goal is reach, visibility, or brand awareness.
For advertisers, CPC can be helpful because costs are tied directly to clicks.
For publishers, CPM can be more predictable because revenue is based on impressions delivered rather than user actions.
Both models can be useful depending on your campaign goals.
The best option depends on whether you care most about traffic, reach, performance, or budget predictability.
