Present-day prize money and ranking points

Challenger tournaments offer total prize money ranging from $30,000 up to $168,000+, which, along with whether the tournament provides ''hospitality'' (food and lodging) to the players, determines the number of points a player gets for winning each match in the tournament.''Hospitality'' moves the points distribution up one level and the points to the overall winner range from 80 points for a $40,000 tournament to 125 points for a $220,000 tournament with ''hospitality''. In contrast, the ATP-level tournaments offer total prize money from $400,000 to over $6 million and points to the overall winners from 250 to 1500.As a point of reference, player rankings are based on points accumulated in the previous 52 weeks, and as of February 2016, a player who has earned 550 points in the last 52 weeks would be ranked just below the 100th position. 250 points would get him a ranking just below 200th, while with 100 points he would get to around 425th, and 50 points would put him just below 600th. So rankings points earned in Challengers can help a low-ranked player to move up in the rankings quickly.
