Director & company secretary Ashley Carson says that the cash windfall from the transfer of Sam Clucas from Hull City to Swansea City will benefit manager Gary Caldwell and help the running of the club.
Clucas is set to join Swansea in a big-money deal and Chesterfield will receive a payment as a result of a clause agreed when he was sold to Hull two years ago.
Carson said: "We have not received official confirmation yet of the fee agreed between Hull and Swansea and we may not be able to disclose the information when we are informed due to confidentiality.
"We do expect to receive a substantial six-figure payment, however, which will result in the budget for players being increased.
"We will also be able to bank a proportion of the funds to help the running of the club, meaning that we don't have to request a further injection of cash from the club owner, Dave Allen.
"A small amount may also be paid out on loans, reducing the current debt."
Carson reveals that the Spireites are to receive a further financial boost soon. He said: "The final payment is coming in from Nottingham Forest for Gboly Ariyibi this month."
