Due to the persistence of spam and phishing, we have generally come to accept them as negative byproducts of eCommerce and online communication with which we must cope. Below I detail the major costs of spam - the costs of phishing are detailed in a subsequent post.

Combined, U.S. corporate and consumer spam are at least a $108.8 billion annual problem, $92.2 billion of which is due to lost consumer and employee productivity and another $16.6 billion in preventative and administrative costs - IT and Helpdesk costs, respectively. The staggering (and rising) costs of both the price of current spam countermeasures and the inefficiencies of these countermeasures implicate a broken model and market. The economic burden of spam is placed entirely on the victims of such perpetration. Furthermore, the only solutions offered to date are not discrete (constantly needing to be updated and paid for regardless of usage) and thus have widely varied results. Hopefully the figures below elicit the same sense of urgency our team has felt for almost a decade. 

Cost of Spam to Businesses

Productivity - $25.5 billion/year

At a price of between roughly $.01 and $.04 per email, spam costs the U.S. economy $25.4 billion annually in lost employee productivity. In total, roughly 80% of all U.S. corporate emails are spam. In 2005, the average U.S. worker received at least 30 spam emails per day with 15% of corporate spam filtered by desktop solutions and 49% filtered at the server level. Beyond automated filtering, 36% of all incoming spam gets manually filtered despite widespread adoption of spam filtering software. Without effective countermeasures, this figure will continue to grow.

IT Costs (Spam Prevention*) - $5.8 billion/year

At an average cost of $2.99 per user per month, the aggregate U.S. corporate IT cost for anti-spam systems is projected to be $5.8 billion in 2009. Assuming all businesses in the U.S. offer this service and will continue to do so especially as spam and phishing become more prevalent, the annual cost for protecting roughly 140 million non-farm employees is not likely to drop below $5 billion.

Helpdesk Costs - $10.8 billion/year

Help desk costs of spam in 2009 are projected to amount to $10.8 billion in the U.S., $33.5 billion worldwide. This estimation entails both the operating cost of a help-desk and the email users’ paid time using the service, particularly to retrieve filtered emails. For corporate email users manually filtering spam, this amounts to roughly 9% of the total cost of spam. For desktop and server filtering, the help desk cost is roughly 39% and 34%, respectively.

Cost of Spam to Consumers

Productivity - $66.8 billion/year

Consumer spam cost the U.S. economy an additional $66.8 billion in productivity loss in 2007. This figure was estimated assuming an opportunity cost of $.04 to delete each of roughly 1.7 trillion annual unfiltered U.S. consumer spam messages received during non-business hours. The collective time spent deleting these messages could otherwise be allocated to non-primary work, volunteer work, education, or other activities that contribute to our overall economic and social development. Although the opportunity cost varies widely by person and is thus difficult to quantify, it is important to identify this problem and is reasonable to assume that the potential value of this lost time is as high as our primary working time.
