1. What is the PIA Formula?

The Primary Insurance Amount (PIA) is the basis for determining Social Security benefits. It's calculated using a formula with three bend points that represent different 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 earnings increase, providing higher replacement rates for lower earners.

3. Importance of PIA Calculation

Details: The PIA determines your Social Security retirement benefit at full retirement age. It's also used to calculate disability and survivor benefits.

4. Using the Calculator

Tips: Enter your AIME amounts for each bend point in dollars. The bend points are adjusted annually for inflation. For 2023, the bend points are $1,115 and $6,721.
