1. What is the PIA Formula?

The Primary Insurance Amount (PIA) is the basis for determining your Social Security retirement benefits. It's calculated using a formula that applies different percentages to portions of your average indexed monthly earnings (AIME).

2. How Does the Calculator Work?

The calculator uses the PIA formula:

Where:

• \( AIME1 \) — First bend point amount (90% replacement rate)
• \( AIME2 \) — Second bend point amount (32% replacement rate)
• \( AIME3 \) — Third bend point amount (15% replacement rate)

Explanation: The formula uses progressive replacement rates that decrease as your earnings increase, providing higher replacement rates for lower earners.

3. Understanding the Bend Points

Details: The bend points are adjusted annually for inflation. For 2023, the first bend point is $1,115, and the second is $6,721. Earnings up to the first bend point are replaced at 90%, between the first and second at 32%, and above the second at 15%.

4. Using the Calculator

Tips: Enter your average indexed monthly earnings for each bend point segment in dollars. The calculator will compute your estimated monthly Social Security benefit at full retirement age.
