The Definitive Guide to Media Jargon – Part 2: Math Behind the Media

Note:  This is the second installment of a two-part blog post covering basic terminology, acronyms, abbreviations and definitions used in media planning and buying.  In case you missed it, read the first here.

As any of my high school math teachers would tell you, becoming an astrophysicist was not in the cards for me.  Just when I thought algebra was my kryptonite, I discovered calculus.  Ouch! Fortunately my love of all things media took me down the road to a communication degree in college – minimal math credits required.

Well it turns out, you can’t hide from math.  Such is true when it comes to media planning and buying, and what I thought was once my kryptonite has found its way to the very heart of everything I do.  Okay, maybe I’m not launching rockets to Mars, but it’s not just bean counting either.

TermCommon Acronym or AbbreviationFormulaDefinition
Ad to Sales RatioA/S= Advertising Cost / Sales RevenueThe ratio of the cost to advertise to the total sales revenue generated – typically reported as a percent.
Average Revenue Per UserARPU= Total Revenue / Total Number of UsersThe average revenue per user is a calculation that allows advertisers to stay apprised of per-user revenue. The ARPU is calculated by taking the total revenue and dividing it by the number of users in a given timeframe for a given platform (mobile app, website, software, etc.).
Click-Through RateCTR= Clicks / ImpressionsThe ratio of clicks to impressions reported as a percent.
CommissionNone= Net Cost / (100% – Commission Rate)A fee based on the percentage of total sales.  For example, determining gross cost using a 15% commission on $1,000 would be calculated as such:  $1,000 / (1 – 0 .15) = $1,176.47.  The commission is $176.47.
Conversion RateCVR= Key Metric / ConversionsReported as a percent, the CVR is the average rate of conversions to the number of times a given key metric is delivered.  Key metrics used are often site visits, impressions or clicks.
Cost Per Action/AcquisitionCPA= Cost / ActionsThe average cost for a defined action or acquisition.  Examples of actions include sales, leads, calls, etc.
Cost Per AssistCP-Assist= Cost / Number of Assist EventsThe average cost in ad spend to obtain an assist within a conversion funnel.  This is a metric defined within an attribution funnel.  There can only be one assist within a path to conversion, and this takes place just prior to the last touch or converter in the path.
Cost Per CallCP-Call= Cost / CallsThe average cost in advertising to obtain one phone call.  This is a pricing unit for some ads as well as a performance indicator.
Cost Per ClickCPC= Cost / ClicksThe average cost to gain a click on a digital ad.  Some ad placements are bought using CPC as the underlying rate basis.
Cost Per Completed ViewCPCV= Cost / Completed ViewsThe average cost in ad spend per completed video view.
Cost Per InstallCPI= Cost / Number of Application InstallsSpecific to mobile applications, Cost-per-Install (CPI) is the price an advertiser pays whenever the consumer installs the advertised application.
Cost Per LeadCPL= Cost / LeadsThe average cost in ad spend to acquire a lead.
Cost Per MilleCPM= (Cost / Impressions) x 1,000The cost to serve one-thousand impressions.  Most display ads are sold based on CPM rates.
Cost Per OriginationCPO= Cost / Number of Originating Paths to PurchaseThe average cost in ad spend to initiate a conversion funnel or path to purchase.  This metric is defined within an attribution funnel and is the first touch in the path to purchase.
Cost Per RosterCPR= Cost / Number of Roster EventsThe average cost in ad spend to generate roster events within a conversion funnel or path to purchase.  Roster events occur after an origination, but before the assist and converter.  There can be multiple roster events within a funnel, and this is generally a measure of cost to build relevant frequency.
Cost Per SaleCP-Sale= Cost / Number of SalesThe average cost in ad spend to generate a sale.
Cost Per ViewCPV= Cost / ViewsThe average cost per view for video ads served.
FrequencyNone= Impressions / ReachThe average number of times an individual or household is reached by a brand over a given amount of time.  It can be applied to paid media, non-paid media, or a combination of both.  For example, an average frequency of ten may be referred to as 10x.
Gross Rating PointGRP= Percent of Market x FrequencyUsed in broadcast media (TV/radio), GRP is a percent of the total market reached multiplied by the frequency.  Total market is generally determined by ratings providers, and a ratings point is equivalent to one percent of the market.  For example, if 30% of your market is reached and you run an ad 5 times, the resulting GRP would be 150 (30% x 5 ads = 150 points).
Mark-UpNone= Net Cost x (100% + Mark-Up)An amount added to a cost of goods or services.  For example, determining gross cost using a 15% mark-up on $1,000 would be calculated as such:  $1,000 x 1.15 = $1,150.00.  The mark-up is $150.
Return On Ad SpendROAS= Sales Revenue / CostThe sales revenue resulting from corresponding advertising.  A positive return on ad spend is reported as a percentage above 100%.  ROAS = Sales Revenue / Cost
Target Rating PointTRP= Percent of Target Market x FrequencyUsed in broadcast media (TV/radio), TRP is a percent of the target market reached multiplied by the frequency.  For example, assuming your target audience is women, if 30% of your total market is reached, and half of that market are women, running an ad 5 times would result in a TRP of 75 (15% x 5 ads = 75 points).
Targeted FrequencyNone = Targeted Impressions / Targeted ReachThe average number of times and individual or household is reached that fall within a specifically targeted demographic.  Examples include household income, gender or age.
