How Is Your Social Security Payout Determined?
An interactive guide to understanding the calculation.
The System in a Nutshell
The U.S. Social Security system provides a safety net for millions. Your future benefit is not a random number; it’s calculated based on your life’s earnings and the age you decide to claim it. This tool will walk you through the core components of that calculation.
First, to be eligible for retirement benefits, you generally need to have worked and paid Social Security taxes for at least 10 years, earning **40 credits**.
Your Earnings Profile
Your benefit is based on your highest 35 years of earnings. To simplify, let’s estimate your average annual earnings over your career. This, along with your birth year, helps determine your baseline benefit.
This determines your Full Retirement Age (FRA).
Earnings are capped at the annual maximum ($176,100 for 2025).
Your Benefit Calculation
Here’s how your inputs are translated into a monthly benefit. Social Security uses a progressive formula, meaning it replaces a higher percentage of income for lower earners. This is done using “bend points” in the formula.
Your Base Benefit (PIA)
This is your monthly payout if you retire at your Full Retirement Age.
$0.00
at your Full Retirement Age of 67.
Based on Average Indexed Monthly Earnings (AIME) of $0.
How Your PIA is Built
The chart shows how different portions of your average monthly earnings contribute to your total benefit.
The Impact of Claiming Age
This is one of the most important retirement decisions you’ll make. You can claim as early as 62, but your benefit is permanently reduced. If you wait past your Full Retirement Age (up to age 70), your benefit permanently increases. Use the slider to see how your choice affects your monthly payout.

Other Key Factors
Your benefit isn’t static once you claim it. Here are two other important concepts to understand.
Cost-of-Living Adjustments (COLAs) ▸
To protect your purchasing power, your benefits are typically increased each year to keep up with inflation. This COLA is based on the Consumer Price Index. For example, benefits increased by 3.2% in 2024.
Working While Receiving Benefits ▸
If you work after you start receiving benefits but before your Full Retirement Age, your benefits may be temporarily reduced if your earnings exceed an annual limit. Once you reach FRA, the limit disappears, and your benefit is recalculated to give you credit for any withheld amounts.
