RFU CEO Francis Baron said the World Cup holder’s inability to win more than two games cost them the cash in sponsorship and TV payments.
Baron said: “We budgeted to win the Grand Slam. The difference between that - receiving 5.5 percent of the TV and sponsorship pool - and coming fourth, where the share is just two percent, was £1m.”
However, the RFU may be able to boost income from its Twickenham stadium, with delays on construction of the new Wembley Stadium potentially pushing more music concerts to the traditional rugby venue.
Failure in the Six Nations rugby has cost the England Rugby Football Union £1m in lost revenue, its chief executive has claimed.
