PR Value Calculator
PR campaign value calculation.
Calculate PR campaign value from media impressions, CPM equivalent rates, and the additional value of tier-1 publication mentions.
What this tool does
This calculator estimates the total value of a PR campaign by combining two measurement approaches. First, it takes your media impressions and applies an advertising-equivalent cost per thousand (CPM) rate to derive an impression-based value—reflecting what equivalent paid advertising would cost. Second, it adds a separate valuation for tier-1 publication mentions, multiplying your count of such mentions by a fixed value per mention. The calculator then sums both components to show your campaign's estimated PR value in monetary terms. The final result depends most heavily on impression volume and your CPM assumption, plus the number and assigned value of tier-1 placements. This approach is commonly used to communicate PR impact to stakeholders. Note that the output is illustrative and doesn't account for factors like audience quality, engagement metrics, brand lift, or sustained business outcomes.

PR value quantifies earned media worth by converting impressions to advertising-equivalent cost. Methodology: impressions × CPM of equivalent paid ad. Plus premium for tier-1 mentions (major publications like FT, Times, major financial markets Journal) valued at 5-20k each due to authority and cascading coverage effects.
5,000,000 impressions × 10 CPM = 50,000 impression value. Plus 3 tier-1 mentions × 5,000 = 15,000. Total PR value: 65,000. Compare to campaign cost: if PR agency cost 10k/month × 3 months = 30k spend, ROI is 117%. Reasonable PR campaigns deliver 3-10x return vs equivalent ad spend.
AVE (Advertising Value Equivalent) has critics. Measures reach, not impact. A Times mention worth 20k AVE might not drive as many customers as one TikTok viral moment at 500 AVE. Best PR measurement combines AVE with business metrics: website traffic spike, brand search lift, lead generation, actual sales attribution. Use AVE as directional guide, not single truth.
Quick example
With media impressions of 5,000,000 and ad equivalent cpm of 10 (plus tier-1 mentions of 3 and tier-1 value per mention of 5,000), the result is 65,000.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Media Impressions, Ad Equivalent CPM (£), Tier-1 Mentions, and Tier-1 Value per Mention. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
What's happening under the hood
Impression value = impressions × CPM ÷ 1000. Tier-1 value = mentions × value per mention. Total = impression + tier-1 value. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
What to do with a low result
A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
5,000,000 × ££10 CPM + 3 × ££5,000 = 65,000.00.

Sources & Methodology
Methodology
This calculator models PR campaign value by combining two components. Impression value is computed by dividing total media impressions by 1,000, then multiplying by the advertising-equivalent cost per thousand impressions (CPM). This treats impressions as equivalent to paid advertising reach at a specified rate. Tier-1 mention value is calculated by multiplying the number of tier-1 media mentions by an assigned value per mention. The total campaign value is the sum of these two components. The model assumes a constant CPM rate and fixed value per mention throughout the campaign period, and does not account for audience quality differences, media outlet weighting, campaign duration effects, or seasonal variations in advertising rates.
