I've been asked to show our accounting people how to write an Excel formula that can calculate the original value after a number has increased by a certain percentage.


For example, we know that the value of 15,002.56 increased by 23% on last month's value and need to work out what last month's figure was.  It seems like it should be simple, but I've been trying for a while now and just can't get it.  Can you help?
