The French Open's total prize money for 2013 has been increased by more than three million euros to €22 million ($28.77 million), organisers said on Monday.
The winners of the men's and women's singles titles will each earn €1.5 million, up €250,000 from last year.
Organisers added that the move was part of plans to boost the total prize money by a further €10 million to €32 million by 2016.
In comparison, US Open prize money will reach $33.6 million this year and rise to $50 million by 2017, while Wimbledon prize money was more than £16 million ($24.61 million) in 2012.
This year's Australian Open prize money was A$30 million ($31.31 million).
