England's Lawn Tennis Association says this year's Wimbledon Championships saw profits jump by 7% to record levels.
Wimbledon made a profit this year of $72 million.
The organisation invests the surplus back into British tennis.
Playing numbers in Britain have also increased and the LTA says Andy Murray's best year to date - including his Olympic gold medal and winning his first Grand Slam at the US Open - played a major part in strengthening the sport at its grass roots.
