If you cannot avoid using linked workbooks, try to have them all open instead of closed, and open the workbooks that are linked to before you open the workbooks that are linked from. Also, you can see the values Excel has read from the closed workbook, which is frequently important for debugging and auditing the workbook. By doing this, you can avoid recalculating all your linked workbooks when you recalculate any workbook.

Try to use simple direct cell references that work on closed workbooks. Some exceptions to this might be when you have many front-end calculations that are so rarely recalculated that it makes sense to put them in a separate workbook, or when you have insufficient RAM. Using fewer larger workbooks is usually, but not always, better than using many smaller workbooks. Avoid links between workbooksĪvoid inter-workbook links when it is possible they can be slow, easily broken, and not always easy to find and fix. It's important to reduce the number of cells in the circular calculation and the calculation time that is taken by these cells. If you have a complex calculation that depends on cells in the circular reference, it can be faster to isolate this into a separate closed workbook and open it for recalculation after the circular calculation has converged. This process is equal to two or three iterations of the calculation.Īfter the circular references and their dependents are identified, each iteration requires Excel to calculate not only all the cells in the circular reference, but also any cells that depend on the cells in the circular reference chain, together with volatile cells and their dependents. Try to move the circular calculations onto a single worksheet or optimize the worksheet calculation sequence to avoid unnecessary calculations.īefore the iterative calculations start, Excel must recalculate the workbook to identify all the circular references and their dependents. Therefore, you usually get slow calculation if your circular references span more than one worksheet. For example, in cash flow and interest calculations, try to calculate the cash flow before interest, calculate the interest, and then calculate the cash flow including the interest.Įxcel calculates circular references sheet-by-sheet without considering dependencies. Frequently you can 'unroll' the circular references by using algebra so that iterative calculation is no longer needed. Minimize use of circular references with iterationĬalculating circular references with iterations is slow because multiple calculations are needed, and these calculations are single-threaded. Forward referencing usually does not affect calculation performance, except in extreme cases for the first calculation of a workbook, where it might take longer to establish a sensible calculation sequence if there are many formulas that need to have their calculation deferred. To increase clarity and avoid errors, design your formulas so that they don't refer forward (to the right or below) to other formulas or cells. Do not use forward referencing and backward referencing
