The RFU is facing revenue losses of up to £50m over the next 18 months due to the coronavirus pandemic.
RFU chief-executive Bill Sweeney said in a statement revealed the figure as he outlined plans to provide a £7m relief package for community clubs affected by the coronavirus pandemic.
RFU executives have agreed to take a 25 per cent pay cut in the face of the global health crisis but the organisation insists it "a firm plan" in place to deal with the losses.
"The RFU had budgeted for a loss-making year within a four-year cycle due to the costs of the 2019 RWC campaign and hosting only two home Six Nations games," Sweeney said.
"The loss will now be considerably more as we face challenges similar to businesses across the country.
"The RFU's biggest asset is also a major cost and the closure of Twickenham Stadium has a significant impact on the revenues we can generate to re-invest back into the game. In that sense we are like every other club in the Union, when we do not stage matches and events we do not generate revenue.
"Based on our planning assumption we estimate RFU revenue losses over the next 18 months to be approximately £45-£50m and have a firm plan in place to mitigate this.
"The RFU Executive Team will be taking a cut in remuneration in excess of 25 per cent. In addition, combined Board fees will be reduced by 75 per cent."
England head coach Eddie Jones is not part of the RFU's Executive Team and therefore is not taking a pay-cut, however, the RFU is in discussions over potential measures that would include coaching staff.
The relief package announced by the RFU includes "monies ring fenced and diverted for the community game as well as additional funding".
According to the RFU, these measures include:
- An early release of £800,000 cash due to clubs through the ticketing fund.
- Early release of final funding payments (£600,000) to Constituent Bodies and suspension of the activity plans against which this was allocated, enabling them to utilise this to provide "immediate support grants" to clubs most in need. In addition £400,000 will be made available to Constituent Bodies who elect to match fund from their own reserves.
- A suspension of the Quarterly loan repayments for clubs with outstanding loans due in April (£335,000).
- The creation of a £5m support loans programme, offering loans of between circa £2k and circa £10k to clubs, with deferred re-payments for six months and repayable over three years.
Earlier on Wednesday, the Welsh Rugby Union has confirmed that a hardship payment of £1,000 has been made to its 320 member clubs.
The 2019-20 domestic season was cancelled last Friday due to the coronavirus pandemic, but a WRU update has detailed a plan for Welsh rugby "to emerge from the current crisis with all teams and clubs, whether they be amateur, semi-professional or professional, intact and able to have a sustainable future".
RFU 'working on assumption' rugby will resume in autumn
The RFU also revealed they are "working on an assumption" that rugby will not return until the autumn but will offer a further update in the middle of April.
Earlier this week, the RFU confirmed the end of the 2019/20 season for all league, cup and county rugby in England except for the Gallagher Premiership.
"Significant progress has been made on the process for considering the implications of ending the season early," Sweeney added.
"We will ensure a fair and balanced outcome for the game and are now committed to update on this by the middle of April.
"No one can predict every possible outcome of the COVID-19 outbreak particularly with regard to the duration of this crisis and we are managing in the unknown.
"We have modelled three potential scenarios and are working on an assumption based on a medium-term impact with a view to a return to rugby in the autumn.
"We will continue to monitor against this assumption and review and revise planning where necessary."
