AARP offers a free easy-to-use calculator that provides great information on how earnings from work can reduce your benefits if you claim before you reach full retirement age. It also provides a recommended claiming strategy in a summary format, but you have no way to dig in and see the data tables supporting the answer.
Some don't find this calculator very useful in developing a good action plan, but it's listed it here because it's so visible. You can choose a for-fee calculator below if you're serious about making your benefit choices work for you. But this calculator is free, so you pay for what you get.
Maximize My Social Security, developed by Boston economics professor Larry Kotlikoff, covers all the Social Security claiming scenarios one might encounter: retiree, spousal, survivor, divorcee, parent, and child benefits. It also does calculations for the windfall elimination provision and government pension offset (which will affect you if you receive a pension from an employer who did not withhold Social Security tax from your earnings—such as a state employee.) It costs $40 for an annual license for an individual and $250 for a financial advisor. Be prepared, this Social Security calculator requires you to input your past and projected earnings history, which you can get from your online Social Security statement.
This calculator provides an overview of several different pre-selected claiming strategies, or you can input your own strategy to see how it stacks up against other options.
