One of the reasons I wrote this book was to help married taxpayers get the most out of their Social Security benefits. Though estimates vary, as many as 97 percent of married Social Security recipients fail to optimize their benefits.
A second reason, very directly related to the first, is that the failure to optimize Social Security benefits frequently imposes significant consequences on the wife who must go on after the death of her husband--statistically the greater probability.
The $214,000 difference referred to in the book title is shown in Figure 3, Single Person Starting Social Security Benefits (Age 62 vs. 70), on page 19. The math for doubling your Social Security can be found on page 20.
All proceeds of this book go to charity: water, a non-profit organization bringing clean and safe drinking water to people in developing countries.
