Roland Garros officials also announced even greater prize-money increases for losers in the middle rounds, becoming the latest grand Slam tournament to cede to player demands for a greater slice of revenue.
In total, 22 million Euros (£18.8million) will be in the prize fund - up 3million (or 16 per cent) on 2012 levels.
Officials announced the rises on Monday, when they also revealed a further 10million Euros would be added the prize fund by 2016.
The players who will benefit the most will be the second, third and fourth-round losers. They will get 25 per cent more money this year than last.
That is what the player bodies, the ATP and WTA, have been seeking as they have argued it is hard for some of the lower-ranked players to meet their expenses accrued on what is a global tour.
The announcement comes just weeks after the US Open devised a similar plan, increasing their prize money to US$33.6 million (£21.9million) for 2013. They have vowed to hit the $50million mark by 2017.
The Australian Open's total for its January tournament was Aus$30million (£20.4million).
The ball is now in Wimbledon's court to come up with a similar increase.
The All England Club, which paid out £16.1million in prize money in 2012, is expected to announce its decision on 2013 levels on April 23.
