Yes, in a manner such that a partial formula is only effected once by a
calculation, and if the result doesn't change, all its dependent cells
aren't recalculated.

I don't know if I understand everyting right,
So to decrease the calculation time it is better to split the formula's up
in more cells, in stead of using a complex formula (and get a direct
result),
I already use dynamic ranges, but it seems to make no difference.
It is not possible for me to use sorted ranges,
Are there any other tips to decrease the calculation time
Thanks for the info so far

Macro functions can be used to reduce the effective number of
dependencies.
(they can also increase the dependencies when done wrong)

To reduce the calculation times, you need to be smart, reduce the
number of
cells dependent upon a change.

Hello,
I have a large data file (10.000 rows / 10 columns) from wich I have
to
process data. I use a lot of index match formula's, lookup tables
and
data
validations, in multiple sheets
Now the calculation of the sheet takes about 25 seconds after each
input.
How can I speed up the calculation time, or calculate only the cells
that
are actualy changed after input.
Any help or information about this matter would be appreciated very
much,
Thanks in advance
