The Women’s Open purse has more than tripled since the last time it was played at the Old Course. 
The jump in the prize money payout from the last time the Women’s British Open was at St. Andrews will shock you
Part of the increase can be ascribed to the overall rise in paydays for women’s professional golf events on the LPGA Tour, and in particularly the five women’s majors, which have each had their purses jump past $7.9 million in the last year.
U.S. Women’s Open: $12 million/$2.4 million
KPMG Women’s PGA: $10.4 million/$1.56 million
Amundi Evian: $8 million/$1.2 million
Chevron: $7.9 million/$1.2 million
