The two teams will contest the Championship play-off final, looking to join Leicester City and Burnley in the top flight, with victory also providing a massive financial boost
For QPR it is a chance to return to the top flight of English football at the first attempt, having been relegated in 2012-13, and, according to Deloitte, promotion will net them a cool £80 million.
Derby, meanwhile, are set to land an even greater financial reward should they prevail, the Rams will win £120m if they win, a higher figure as should QPR fail they will continue to receive parachute payments.
Adam Bull, senior consultant in the Sports Business Group at Deloitte, has also outlined how playing in the Premier League will boost either club’s accounts next season.

"This will be at least £60m for Derby County and at least £40m for QPR, who are already in receipt of Premier League parachute payments.
"The vast majority of this uplift will be from broadcast income as the Premier League enters the second year of its greatly enhanced three year TV deals."
Steve McClaren’s side finished the season third, five points ahead of QPR, who will be all too aware that the team finishing fourth has failed to win promotion since 1998.
Indeed, Harry Redknapp claims Derby are favourites for the game and has praised his opposite number for the impact he has had at the club since taking over from Nigel Clough in September.
"It's a massive game: obviously we want to get back in the Premier League and there's an awful lot at stake," Redknapp told reporters.
"Both teams have got pros and cons but I think they're the favourites and the bookmakers make them the favourites.
"They've been in good form and Steve McClaren has done a fantastic job with them, they're a young side and full of energy."

Derby’s last stint in the Premier League came in 2007-08 and McClaren has urged his players not to get carried away.
"It will be a great occasion and it is important that we treat it like a normal game," said McClaren.
"I understand that the stadium we will be playing in is bigger and the occasion is a big one, but the pitch is the same, the dimensions are the same and we have to treat it as another game."
Championship winners Leicester City and runners-up Burnley have already secured their places in the Premier League and Bull says the figures should promoted teams do well.
"The newly promoted clubs are often the bookies’ favourites to be relegated, but in every one of the past six seasons, at least two of the three promoted clubs have successfully retained their Premier League status in that crucial first season," he added.
"Recent history also shows play-off winning clubs have nothing to fear; in the last three seasons not only have they all avoided relegation, they have also finished in the highest position of the three promoted clubs. The success stories of Swansea City and Crystal Palace should only serve as motivation for this year’s play-off winners."
