Increase the number of decimal places displayed in cells O30 and O53,
and you will see why. The displayed value is an approximation of the
real underlying value. Use ROUND( ... ,3) in your formulae to avoid
these errors.

Hope this helps.

Cell O56 is the sum of O30 and O53 and the answer is coming € 1927.814
instead of € 1927.815
All the 3 cells are in currency and to 3 decimal places.
Why the answer is coming with a difference of .001

Thanks for your help.
