The figures were outlined in United’s 2019-20 financial statement, which took in the period during which English football was closed down completely.
United’s overall revenue was down 18.8% from £627.1m to £509m but part of this was due to the club not qualifying for last season’s Champions League.
In last year’s statement, United had estimated revenues could reach £580m.
“Our focus remains on protecting the health of our colleagues, fans and community while adapting to the significant economic ramifications of the pandemic,” said the club’s executive vice-chairman Ed Woodward.
“Within that context, our top priority is to get fans back into the stadium safely and as soon as possible.”
