[Jose]

I have sheet with many formula. However, it take 10 min to calculate after a

What is your formula? How many do you have? Are there any macros?

In short, without a LOT more information it is unlikely you' ll get any specific help.
You may have a look at Charles Willima's site:
www.decisionmodels.com
which has lots of info about performance of Excel
