A marketing campaign typically costs about 10-30 percent of the entire company’s budget in a year. However, newer companies looking for publicity usually spend about 50 percent. The cost of a marketing campaign depends on the seriousness of it, especially if the campaign is expected to improve sales dramatically. A marketing campaign can be undertaken in a number of modes, ranging from road banners to e-newsletters. The expenses are usually lower for online marketing campaigns, although charges of programming can vary.
