Exeter are in their fourth successive season in the third tier of English football – their longest spell at that level since the early 1990s.
In that time the club has built new training facilities and a new stand at St James Park.
Caldwell says the club has regularly punched above its weight when compared to the budgets available to their rivals in League One.
“I think we’ve been seven, 10 and six places above our financial budget in the financial table – I’m sure the EFL released something this year that 80% of that table was where you finish in terms of your finances,” he added.
“So we know the challenge, we know it’s big, but I haven’t seen anyone in my time here take a backward step from that challenge.
“Everyone does their job and a little bit more to try and get the best for Exeter City and I think at this moment in time it’s probably a bit of a time for change and what does the future look like at League One for our football club?
“It’s for people above me to make those calls, but all I know is that the support I get from everyone at the club is first-class and it gives me an opportunity to do my job as best I can.”
