The benchmarking exercise allowed the charities taking part to compare how others of the same size allocate their budgets to different functions.
Detailed results cannot be divulged because of a confidentiality clause. However, IT was identified as one area where spending varied significantly between charities.
Jackie Taylor, the chair of the SCFDG costs group and assistant director of ELCAP, the charity that works with people with disabilities and their families, said: "I learnt that I'm not spending as much on IT as many of the others. This is evidence I can take to my board for future budgets."
The exercise also gave a useful insight into how much money different charities were spending on human resources, finance and other activities, she said. The SCFDG group is to repeat the exercise later this autumn.
