Hey Venkateshwarrao,

Use the rollup summary that is the easiest way to achieve it.

Hi Venkatesh,

There is no need for writing code if there is Master Detail relationship between Account and Contact. You can create a new roll up summary field on Account that counts the number of child Contact records.

Hi  Venkateshwarrao - The standard Account and Contact are not master detail relationship so you can't have rollup summary field. There are two ways to implement the rollup-summary for the Lookup relationship Thanks,

Yeah, But when we select the object while creating Rollup summary on account it not shows the contact.its show only oopurtunity object. so we have to write the trigger i thought... Please once try it if any result send back
