The salary cap – a £6.4m limit on squad spending, albeit with ‘credits’ on offer for home-grown talent and other factors which stretch the restriction to £7.8m – will remain the same.
Fly-half remains the highest paid position in the Prem on £260,000, with back row second at £192,000.
The lowest paid position is wing on £132,000, with prop on slightly more on £144,000.
Like Russell, Sale’s George Ford, Marcus Smith at Harlequins and Saracens’ Maro Itoje are among the excluded players, with their average salary £533,000.
Bottom side Newcastle spent the least of all clubs and failed to reach £4m overall.
“The cap continues to be supported by all and it is central to driving the competitiveness of the Prem,” chief executive Simon Massie-Taylor said.
“With six different winners in as many years, we should all be proud of our system that ensures that any club, on any given day, can compete for the biggest prize in English rugby.”
Together with their first league title since 1996, Bath lifted the Premiership Rugby Cup and European Challenge Cup last year.
