https://maximizemysocialsecurity.com/households http://www.socialsecuritysolutions.com/getyoursolution.php (also has an option to get help from an advisor)Some of the online software is free to use but please be cautious.

If you have 2 or 3 sources giving you the same advice, there's comfort in that.
