The exact profit of your radio station will obviously depend on factors ranging from audience size to programming cost to the amount of advertisers. However, the most popular local radio stations in the country are able to make over $60 million in ad revenue each year. While your station is not likely to hit those numbers any time soon, this helps represent the potential of revenue via selling advertisement space—the amount you charge will only go up as your number of listeners grows while your operating expenses are relatively fixed, so a station that grows in popularity is a very good investment.
