I have never used stack-overflow so I apologize if my question is formatted incorrectly. Currently I am working on an excel workbook that is basically every single financial sheet in a company (operations staffing, IS costs, warehousing, marketing expenses, CAPM calculations, income statement, you name it) and we are trying to use Goal Seek in order to do a sensitivity analysis on a few variables. Basically we are trying to see how much does x need to change % wise in order to have NPV = 0 (breakeven) so we can analyze risk. The issue comes when goal seek can't find a solution and tells us there is a circular reference. We have spent nearly 6 hours confirming there are no circular references. Additionally, if I change the sensitivity manually I can get NPV to breakeven, but goal seek can't. Has anyone encountered this before? There are no macro codes being used in this excel file and we can't for the life of us figure out what is happening.
Please help!
