The 2017.1 or 2017.2 versions of the Social Security Benefit
Calculator can be updated to include the newly announced
amounts. The amounts required for updating the 2017 versions
of the Social Security Benefit Calculator are as
- Cost-of-living adjustment for December 2017: 2.0 percent

To update a 2017 version of the calculator, choose
Properties from the main menu, then Historical
Amounts, then Update. If the dialog box that appears
requests amounts for 2018, enter the above amounts.
If it requests amounts for 2019 or later, then the

case, press Cancel, then choose Properties,
Historical Amounts, and Modify. In the dialog box
that appears, press Next Year or Previous Year

When you are ready to use the newly entered amounts, choose
Properties from the main menu, then Computation
Year. In the dialog box that appears, enter 2018.
The calculator will now produce 2018-style estimates, except that
the stored assumptions (from the 2017 or older Trustees Report) will
not be updated. To have a fully up-to-date calculator, you should
download the new version.
