Cost-per-contact is a public relations metric that shows how much it costs to reach one person in the target audience. In Intro to Public Relations, it is used to judge whether a campaign is reaching people efficiently.
Cost-per-contact is the amount of money a public relations campaign spends to reach one individual in its target audience. In Intro to Public Relations, it is one of the basic ways to think about whether a PR effort is efficient, not just whether it looks successful on the surface.
You calculate it by dividing the total cost of a campaign by the number of people contacted or reached. If a media outreach push costs $2,000 and reaches 10,000 people, the cost-per-contact is $0.20. That does not mean every person was personally persuaded, only that the campaign got the message in front of each contact at that average cost.
The term is especially useful when you compare different tactics. A press release picked up by several local outlets may have a much lower cost-per-contact than a small event with limited attendance. A social post can also look cheap on paper, but in PR you still have to ask whether the audience reached was the right one, not just the biggest one.
That is why cost-per-contact is not the same as overall success. A low number can be good if the people reached are part of the target audience, but it can also be misleading if the contacts are not relevant. A campaign that reaches a lot of people at a low cost may still fail if those people do not care about the message or do not fit the stakeholder group.
In PR work, this metric often shows up during campaign planning, budget review, and post-campaign reporting. It gives communicators a simple way to compare channels like earned media, events, email outreach, or sponsored placements. When you see cost-per-contact in this course, think: how much did it cost to get the message in front of one person, and was that spend worth it for this audience and goal?
Cost-per-contact matters because Intro to Public Relations is not just about writing good messages, it is also about proving that communication choices make sense. PR teams often need to explain to managers, clients, or stakeholders why one outreach strategy was better than another, and this metric gives them a clear financial comparison.
It also connects directly to ROI, which is a major idea in PR measurement. If two campaigns produce similar exposure, but one reaches the audience at a much lower cost, the cheaper one may be the stronger investment. That said, a low cost-per-contact does not automatically mean the campaign achieved its communication goal, so you have to pair it with other measures like media impressions, engagement rate, or earned media value.
The term helps you think like a PR planner. Instead of asking only, “How many people saw this?” you also ask, “What did it cost to get that exposure?” That shift matters in real campaigns where budgets are limited and every tactic competes for resources.
It also shows the difference between reach and impact. A press mention might be inexpensive, but if it lands in the wrong outlet, the cost-per-contact may look good while the campaign still misses the people who matter most. This is why PR measurement usually combines cost-per-contact with audience fit, message penetration, and broader campaign goals.

ROI is the broader financial question behind cost-per-contact. Cost-per-contact shows the cost of reaching one person, while ROI asks whether the campaign’s results justify the total spend. In PR, you often use both together: one metric explains efficiency at the contact level, and the other explains whether the campaign made business sense overall.
Media Impressions
Media impressions count how many times a message could be seen, but they do not tell you what each impression cost. Cost-per-contact adds the budget side of the picture. If two campaigns generate similar impressions, the one with the lower cost-per-contact may be the more efficient outreach choice, depending on who was actually reached.
advertising value equivalency
Advertising value equivalency tries to estimate how much earned media coverage would have cost as advertising space. Cost-per-contact is different because it focuses on the expense of reaching each person, not the dollar value of the coverage itself. Students often compare them because both are measurement tools, but they answer different questions.
earned media value
Earned media value estimates the worth of publicity that was not paid for directly, such as news coverage or mentions. Cost-per-contact helps you judge how efficiently that coverage reached people. Together, they can show whether a PR effort was both inexpensive to deliver and valuable in the amount of attention it created.
A quiz question may give you two campaign options and ask which one has the better cost-per-contact, or it may ask you to interpret a budget table from a PR case. You would divide total campaign cost by the number of contacts reached, then explain what the result says about efficiency. If the question is more conceptual, be ready to say that a lower cost-per-contact is not automatically better unless the audience reached matches the campaign goal.
In short-answer or discussion prompts, you might use the term to defend a channel choice, like explaining why a media pitch, event, or sponsored post was a smarter budget use than a broader but less targeted tactic. The strongest responses connect the math to the communication strategy, not just the number.
Cost-per-contact and cost-per-impression sound similar, but they are not always used the same way in PR. Cost-per-contact focuses on the cost of reaching one person in the target audience, while cost-per-impression is tied more directly to the cost of each exposure or view. In practice, cost-per-contact is often the more audience-centered way to talk about PR efficiency.
Cost-per-contact tells you how much a PR campaign spends to reach one person in the target audience.
You calculate it by dividing total campaign cost by the number of contacts reached.
A lower cost-per-contact can signal better efficiency, but only if the people reached are actually the right audience.
The metric works best when you compare it with ROI, media impressions, and engagement rate.
In PR, cost-per-contact helps you judge whether your budget is buying useful exposure, not just activity.
Cost-per-contact is the average amount of money a PR campaign spends to reach one person in its target audience. It is a measurement of efficiency, so it helps you judge whether a communication tactic is worth the money. In PR, it is most useful when you compare campaigns, channels, or outreach methods.
Take the total cost of the campaign and divide it by the number of people it reached. For example, if a campaign costs $500 and reaches 2,500 contacts, the cost-per-contact is $0.20. That simple formula makes it easy to compare different PR efforts, even if the tactics are very different.
No. Media impressions count how many times a message could be seen, while cost-per-contact measures the cost of reaching each person. A campaign can generate lots of impressions but still have a weak cost-per-contact if it was expensive to run. The two numbers often work together, but they do not mean the same thing.
It gives PR teams a way to show whether they used their budget efficiently. That matters when you have to choose between tactics like events, outreach, social posts, or earned media. It also helps you explain campaign results to managers or clients without relying only on vague claims about awareness.
