Free online Social Security benefits calculator

Social Security benefits depend on your earnings history and the age you claim. This calculator estimates your monthly benefit from 62 to 70 and compares claiming strategies by.

About this calculator

How to use

  1. Enter your birth year — this sets your Full Retirement Age.
  2. Enter your average annual earnings (a rough estimate works for planning purposes).
  3. Select the age you plan to start claiming benefits (62–70).
  4. The calculator shows your estimated PIA, monthly benefit at your chosen age, and a comparison table for every claiming age.

The formula

Step 1 — AIME

AIME = average annual earnings / 12

Step 2 — PIA (2024 bend points)

PIA = 90% × min(AIME, $1,174)
    + 32% × max(0, min(AIME, $7,078) − $1,174)
    + 15% × max(0, AIME − $7,078)

Step 3 — Adjusted benefit

  • Before FRA: reduce by 5/9% per month for first 36 months early, then 5/12% per month beyond.
  • After FRA: increase by 2/3% per month (8%/year) up to age 70.

Worked example

Birth year 1960 (FRA = 67), average earnings $70,000/year:

  • AIME = $70,000 / 12 ≈ $5,833
  • PIA = 0.9 × $1,174 + 0.32 × ($5,833 − $1,174) = $1,056.60 + $1,490.88 ≈ $2,548
  • Claiming at 62 (60 months early): 30% reduction → $1,784/month
  • Claiming at 67 (FRA): $2,548/month
  • Claiming at 70 (36 months late): 24% increase → $3,160/month

Frequently asked

What is the Primary Insurance Amount (PIA)?
The PIA is your monthly benefit if you claim exactly at your Full Retirement Age (FRA). It is calculated from your Average Indexed Monthly Earnings (AIME) using a progressive bend-point formula set by the SSA each year.
What are the 2024 bend points?
The 2024 PIA formula applies: 90% to the first $1,174 of AIME, 32% to AIME between $1,174 and $7,078, and 15% to AIME above $7,078.
What is Full Retirement Age (FRA)?
FRA is the age at which you receive 100% of your PIA. It is 66 for those born in 1954 or earlier, 67 for those born in 1960 or later, and slides from 66 to 67 for birth years 1955–1959 (two extra months per year).
How much is the benefit reduced for early claiming?
Benefits are reduced by 5/9 of 1% per month for the first 36 months before FRA, and 5/12 of 1% per month for any months beyond that. Claiming at 62 with a FRA of 67 results in a 30% reduction.
How much is the benefit increased for delayed claiming?
Delaying past FRA earns Delayed Retirement Credits of 8% per year (2/3 of 1% per month) up to age 70. At 70 with FRA 67, the benefit is 24% higher than the PIA.
What is the break-even age?
The break-even age is when the cumulative lifetime benefit from a later start date equals the cumulative benefit from an earlier start. If you live past the break-even age, the later strategy pays more in total.
