Although he has said there was always a small risk tournaments could be cut from the schedule if they did not secure financial backing, he was optimistic solutions would be found.
"We continue to navigate the choppy waters of the downturn, we've made a lot of progress," Finchem told reporters on Tuesday in the build-up to the Tour Championship at East Lake Golf Club.
"In this last 18 months, we've announced 20 either new sponsors or extensions of sponsorships that are major in nature, an increasing number of tournaments being taken out (extended) to 2015 and 2016, so we're delighted about the progress that we've made."
This year's PGA Tour features 47 events, including a tournament in China in early November.
Among those yet to secure a major sponsor for next season are the World Golf Championships event in Miami and the tournament at Hilton Head Island in South Carolina, held the week after the U.S. Masters.
"We have a long way to go, but the strategies we've employed seem to have been working. The players have done their part, and we continue to be able to maintain somewhat of a growth curve in this down economy."
Finchem expressed delight in a 2010 PGA Tour season which has yielded a number of victories by emerging young talents as well as several by the established names.
"I can't remember a year when we've had more buzz, more interest and more questions from fans about the younger players.
Americans Johnson and Mahan and Britain's Justin Rose have each triumphed twice this season. Northern Irishman McIlroy, aged just 21, shot a course record 10-under-par 62 to win the Quail Hollow Championship by four strokes in early May.
"Overall, when you look back over it, the competition has been terrific this year," Finchem said.
