Effective Facebook advertising involves countless variables – audience targeting, marketplace competition, bidding strategies, conversion rates, and so much more.

To cut down on some of the uncertainty and provide digital marketers with a better sense of what to expect for campaign reach and spend, we’ve built a simple ad budget calculator based on Nanigans’ years of deep social and mobile advertising experience.

Whether you’re getting started on a new social channel, testing new audience combinations, or looking to scale revenues from your digital advertising, this ad budget calculator will help you estimate ad spend based on target audience size and ad units leveraged.

Note that the estimated CTR and expected CPM are sourced from both Facebook desktop and mobile ad spend, and exclude Facebook Exchange and dynamic product ads. This data is representative of Facebook ad impressions delivered by customers leveraging Nanigans advertising automation software, so it may not necessarily be a proxy for the overall Facebook marketplace—and overall should be taken as a guideline rather than an exact metric.
