Salop's CEO has revealed the extent of the club's loss since the start of the pandemic in March 2020 - with parts of the club's revenue streams not back to the level they were at before Covid-19.
And he has also revealed the stark reality facing Shrewsbury and other clubs when it comes to the cost of living crisis and increased utility bills.
Currently Salop power bills are at £80,000 to £100,000 a year but they look set to rise to anywhere between £160,000 and £200,000.
Speaking to the Daily Mail, Caldwell said: "I don't know how some clubs survived Covid and now there's another crisis coming with the increasing utility bills.
"Increasing costs are a worry. Our power bill is probably going to double, that's quiet frightening and the same problems are affecting supporters.
"What if a football ticket becomes a luxury some can't afford? What if they decide to save £22 on a match ticket?
"When the increased energy costs kick in, it will be October and November, the World Cup will be starting and there will be three or four games a day live on television.
"Are they going want to come out and watch Shrewsbury three times a month? That would be catastrophic for the clubs in Leagues One and Two where match-day income can represent 40-50 per cent of turnover.
"Football is awash with money at the top level, but clubs in League One and Two are on their knees, going from one crisis to another."
One suggestion that has been made to combat the issue has been bringing kick offs in the EFL forward to midday to avoid bigger floodlight bills.
However, that would lead to more overnight stays for teams.
One night in a hotel for Salop would cost £2,000 to £3,000 last season but now costs more than £4,000, and up to £6,000 in London
On the idea Caldwell added: "Yes we'd save on power but we'd be robbing Peter to pay Paul."
