ATP World Tour Finals 2015 prize money: £1.5m earnings boost on offer for Novak Djokovic, Andy Murray, Roger Federer and others at O2 Arena
Up to £1.5m in prize money is on offer for the eight best mens' tennis players at the ATP World Tour Finals at this year.
The ATP Tour's curtain call event in London is the most lucrative of the year outside the four Grand Slams with a $2.28m (£1.5m) cash prize awarded to an undefeated champion.
Each player will pick up a participation fee worth around £110,000 just for turning up. They will then be awarded the same amount for a win in the round robin stage, around £330,000 for a semi-final victory, roughly £690,000 for winning the final and £1.5m for winning a maximum five games.

The ATP World Tour Finals, which pits the eight highest-ranked mens' tennis players in the world against each other, will take place at the O2 Arena for the seventh year in succession on Sunday.
Home favourite Andy Murray, who has never won the event, has been drawn in a group with Stan Wawrinka, Rafael Nadal and David Ferrer.
Novak Djokovic, Roger Federer, Tomas Berdych and Kei Nishikori make up the other group.
The competition's big prizes are supported by its commercial success since arriving in London.
Last year over 260,000 flocked to the Greenwich arena prompting the ATP to extend the stay of the tournament in the capital to 2018.
Djokovic will be the man to beat this year: The world No1 has enjoyed his trips to South London having triumphed every year for the last three years – a streak worth over £3m to his bank account. Another title next week will make him the first man to win four on the bounce since Ivan Lendl in 1987.
Another domineering year has seen him already pocket $16.8m (£11m) in prize money – over $10m more than anyone else – and has already broken his own record for the most amount of money won in a single season.
Should Djokovic make it four from four in London, he will take his career earnings over the $90m mark.
Only Federer, who has won twice in London, has earned more with $95.2 picked up across a glittering career.
