Create a trigger on Contact that triggers on "after insert", "after update" and "after delete".
Find all related account ids.
Do a soql query of all those accounts with related contacts.
Calculate the new sum for each account by summing all contacts for each account.
Update only those accounts where the sum actually changed.
