You can reach me at

Please be aware that I cannot reply to every email. I'm eager to hear constructive input about the calculator, but I cannot serve as tech support, nor can I provide a personal Social Security consultation.

If you believe you have found a bug and would like to report it, it would be most helpful if you could include the inputs that you provided to the calculator, as well as the browser that you are using.

If you're looking for more information about how this calculator works, please see the About page. Alternatively, you can view the source code on GitHub:
