The difference on the 1958 tour in terms of the percentage of the gate between Hoad and Gonzales was not huge. Both players received 20% of the gate every night, but Hoad would get an extra 5% on those nights which he won, or 25% of the gate. The final score was 51-36 for Gonzales, so that did not amount to a huge difference. On those 51 Gonzales wins, there was no difference in the percentage of gate for the two players.
According to Kramer, Hoad earned over GBP £50,000 (US$140,000) in the first 11 months of his pro career (through May, 1958). That included the 4-man tour of Europe, Asia, and Australia in late 1957.
Hoad won the richest tournament of the 1958 season at Kooyong Tournament of Champions in which he received AUS£2,500 (US$5,600) for his win, US$6,160 including doubles returns.
Kramer stated that he paid Hoad US$140,000 through May, 1958 and US$225,000 through June 1959.
A newspaper report indicates that officially Hoad earned $47,575 in winnings through June, 1959 for the season beginning in Jan 1959. Another newspaper report indicates that Hoad made about $70,000 in winnings for the entire 1959 season, in which he played about 170 matches.
Hoad's biographers estimated that Hoad earned about $200,000 through December 1958 from July 1957.
So these numbers are all roughly on target to Hoad getting about $100,000 US per year from July 1957 to January 2, 1960, about $250,000 for 2 1/2 years.
After Jan 1960, Hoad played much less and signed a new 7-year contract with Kramer for presumably less money. Hoad played well over 300 matches in that first 2 1/2 year period, but only about 35 matches in 1960, about the same in 1961, perhaps about 50 matches in 1962 when the pros did not play in the U.S., few matches in 1963.
