Hi Sai,

Using for loop inside a for loop is not a good practice in Salesforce. please find the code to full fill your requirement.

trigger calculateAmount on Contact (after Insert,after delete) {
    
    list<contact> upcommingContacts=trigger.isInsert?trigger.new:trigger.old;
    
    list<contact> updatedContactList=new list<contact>();
    set<string> accountIdSet=new set<string>();
    for(contact c:upcommingContacts){
        if(c.accountid!=null){
            accountIdSet.add(c.accountId);
        }
    }
    
    map<string,integer> getAnnualRevenueMap=new map<string,integer>();
    map<string,integer> getNoOfContactPerAccount=new map<string,integer>();
    list<account> acclist=new list<account>([select id,AnnualRevenue,(select id,accountId,Amount__c from contacts) from account where id=:accountIdSet]);
    
    for(account a:acclist){
        if(a.AnnualRevenue!=null){
            getAnnualRevenueMap.put(string.valueOf(a.id),integer.valueOf(a.AnnualRevenue));
            getNoOfContactPerAccount.put(string.valueof(a.id),integer.valueOf(a.contacts.size()));
        }
    }
    
    for(contact con:[select id,Amount__c,accountid from contact where accountid in:accountIdSet]){
        if(con.accountId!=null){
            integer anRev=getAnnualRevenueMap.get(con.accountId);
            integer recordCount=getNoOfContactPerAccount.get(con.accountId);
            
            integer finalAnount=anRev/recordCount;
            con.Amount__c=finalAnount;
            updatedContactList.add(con);
        }
    }
    
    if(updatedContactList.size()>0){
        try{
            update updatedContactList;
        }
        catch(exception ex){
            system.debug(ex.getMessage());
        }
    }
}

Hello,

Please try below code: 
trigger DistributeRevenue on Contact (after insert, after delete) {
    Set<Id> accountIds = New Set<Id>();
	List<Contact> contactsToUpdate = New List<Contact>();
	for(Contact con:Trigger.New){
		accountIds.add(con.AccountId);
	}
	if(trigger.isDelete){
		for(Contact deleteContact:Trigger.Old){
			accountIds.add(deleteContact.AccountId);
		}
	}
	if(accountIds != null){
		List<Account> accountAndContactsToUpdate = [Select Id, AnnualRevenue__c, (Select id, Amount__c from Contacts) from Account Where ID IN :accountIds];
		for(Account acc: accountAndContactsToUpdate){
			for(Contact con : acc.Contacts){
				con.Amount__c = (acc.AnnualRevenue__c) / acc.Contacts.size();
				contactsToUpdate.add(con);
			}
		}
	}
}

Try Below code: 
trigger DistributeRevenue on Contact (after insert, after delete) {
    Set<Id> accountIds = New Set<Id>();
	List<Contact> contactsToUpdate = New List<Contact>();
	for(Contact con:Trigger.New){
		accountIds.add(con.AccountId);
	}
	if(trigger.isDelete){
		for(Contact deleteContact:Trigger.Old){
			accountIds.add(deleteContact.AccountId);
		}
	}
	if(accountIds != null){
		List<Account> accountAndContactsToUpdate = [Select Id, AnnualRevenue__c, (Select id, Amount__c from Contacts) from Account Where ID IN :accountIds];
		for(Account acc: accountAndContactsToUpdate){
			for(Contact con : acc.Contacts){
				con.Amount__c = (acc.AnnualRevenue__c) / acc.Contacts.size();
				contactsToUpdate.add(con);
			}
		}
	}
	update contactsToUpdate;
}

Hope this will work.
