The planner computes the Full Retirement Age (FRA) for both you and your spouse (if applicable) from your data, and you will input the Primary Insurance Amount (PIA) and the age at which you claim. Using this data, the planner will apply early retirement reductions or delayed retirement credits to your PIA to determine your benefits at claiming age.

The planner will also automatically calculate spousal benefits. For you and your spouse, the tool will use your own benefit or your spousal benefit, whichever is greater.

Additionally, at longevity age of the first spouse, the model will assume the surviving spouse will receive 100% of the deceased’s benefit, if greater.

First, you need to know your benefit and your spouse's benefit at full retirement age. You can obtain this information by looking up your benefit information on the Social Security Administration website, www.ssa.gov.

Step 1: Head on over to My Plan > Income > Social Security

Step 2: Use the pencil icon ✎ to edit. If you plan on receiving benefits, press "Yes" when asked if you expect to receive Social Security benefits

Step 3: Enter your benefit at full retirement age

Step 4: Select the age when you wish to claim your Social Security benefit. Your Benefit at Start Age (Pretax) will adjust, increasing if you delay past your Full Retirement Age and decreasing if you claim early.

Step 5: Repeat the process for your spouse's benefit (if applicable)

Use the pencil icon to edit back to the Social Security setup and press "No" when asked whether you expect to receive Social Security. See a video demonstration here.
