I have two cells, Cell "A" and cell "B", that have a formula in each. Cell "A" has a value that is correct and Cell "B" has a value that is correct. I now have a third cell (cell "C") with a formula that takes the values of cell "A" and cell "B" and multiplies them. The value of the product is wrong in cell "C" as compared to a value performed by a calculator. Cell "C" reports 51,550.64 whereas the calculator reports 51,540. What is the problem.

Thanks

I'm willing to bet that the number you are entering into the calculator are rounded off while the number that Excel is using is not truly rounded off. Even though Excel may display a certain number in a cell due to its format, it is probably using the true value of the number which probably includes several decimal places. What numbers are showing in cells A and B? How are cells A and B formatted? What happens if you increase the number of decimal points in these cells...do the cell number become larger? If so, then Excel is likely using the true values of the cells instead of the display values in its calculations. Provide details of how you are obtaining your cell values so we can confirm that this is happening.

Try the following

TOOLS --> OPTIONS and choose the Calculation Tab. Put a check in the box marked "Precision as Displayed."

NOTE: This will affect all other calculations on the workbook causing changes to other values on the sheet!

Iwould agree with Rollin Again. My guess is that you are using truncated numbers in the calculator.

Hi,

Just as a side note, as I agree with the above, an option instead of going to Precision as Displayed - I'm not a big fan of that - is when massaging your data to use (in all intermediary calculations also) some sort of ROUND function. As you can see, when used (especially over multiple cells) your values can become quite a bit off. There are many options.
