How are benefits determined?
First, the Social Security Administration (SSA) determines eligibility for receiving benefits based on credits earned over the years of work. Workers earn up to 4 credits per
year based on income. Generally, 40 credits (10 years of work) are required for retirement benefits. For example, you earn 1 credit in 2024 for every $1,730 of earnings.
Monthly benefits are calculated based on your lifetime earnings and the age at which you begin receiving benefits. The higher the earnings and older the age (up to 70) at which
you begin receiving benefits, the higher the monthly benefit amount.
Earnings History
The Social Security Administration (SSA) calculates your benefits based on your Average Indexed Monthly Earnings (AIME), which represents your highest 35 years of earnings,
adjusted for wage inflation. The method for this calculation is as follows:
- Indexing Earnings - Your past earnings are adjusted to reflect changes in average wages over time, ensuring that your benefits account for wage growth.
- Calculating AIME - The SSA sums your highest 35 years of indexed earnings and divides by 420 (the number of months in 35 years) to determine your AIME.
- Primary Insurance Amount (PIA) - The SSA applies a formula to your AIME to calculate your PIA, which is the monthly benefit amount you'd receive at your Full
Retirement Age (FRA). For example, for individuals turning 62 in 2024, the PIA is calculated as 90% of the first $1,174 of AIME, plus 32% of AIME over $1,174 and up to $7,078, plus
15% of AIME over $7,078.

Age at Claiming Benefits
The age at which you choose to start receiving Social Security benefits significantly impacts your monthly benefit amount:
- Full Retirement Age (FRA) - This is the age at which you're entitled to 100% of your PIA. For individuals born between 1943 and 1954, the FRA is 66; it gradually
increases to 67 for those born in 1960 or later.
- Early Retirement - You can begin receiving benefits as early as age 62; however, your monthly benefit will be reduced to account for the longer period over which
you'll receive payments. For example, if your FRA is 67 and you start benefits at 62, your monthly benefit would be reduced by about 30%.
- Delayed Retirement - Delaying benefits past your FRA increases your monthly benefit due to Delayed Retirement Credits (DRCs). Benefits increase by approximately
8% for each year you delay claiming up to age 70, at which point would be 124% of your PIA.
How do you maximize your benefits?
Working for at least 35 years and earning higher wages during those years can increase your AIME, leading to a higher PIA. Delaying benefits can result in higher monthly payments,
which may be advantageous if you anticipate a longer lifespan or have other income sources to support you in the interim. However, if you have health concerns or immediate financial
needs, claiming earlier might be appropriate, despite the reduced monthly benefit. If you have a spouse or partner and their benefits are less than 50% of your PIA, you might be able
to maximize the overall benefits by having your spouse or partner claim benefits at age 62 and then later claim your own benefits at age 67 or higher along with spousal benefits.
What will reduce benefits?
There are a number of things that can actually reduce your monthly benefit.
- Claiming Benefits Earlier - If you claim benefits before your Full Retirement Age (FRA) (e.g., age 62), your monthly benefit will be permanently reduced by as much
as 30% to account for receiving benefits over a longer period.
- Earning Income While Receiving Benefits - If you claim Social Security before FRA and continue working, your benefits may be reduced temporarily if your earnings
exceed the annual earnings limit. In 2024 before FRA, the limit is $22,320 per year ($1,860/month). For every $2 earned over this limit, $1 is deducted from your benefits. In the
year you reach FRA, the limit is higher ($59,520 annually), and $1 is deducted for every $3 earned over the limit. After you reach FRA, there is no earnings limit, and benefits are
recalculated to include the amounts previously withheld.
- Taxes on Benefits - Your benefits may be taxed depending on your combined income (adjusted gross income + nontaxable interest + half your Social Security benefits).
- Government Pension Offset (GPO) - If you receive a pension from a government job (federal, state, or local) where you did not pay Social Security taxes, your spousal
or survivor benefits may be reduced by two-thirds of your government pension.
- Windfall Elimination Provision (WEP) - The WEP applies to workers with a pension from a job that didn’t pay into Social Security but who also worked in other jobs
covered by Social Security.
How are benefits taxed?
Social Security benefits may be subject to federal income tax depending on your combined income and filing status. Here's a breakdown of how Social Security benefits are taxed:
Calculate combined or provisional income
The IRS uses your combined (provisional) income to determine if your Social Security benefits are taxable. Combined income is calculated as:
Combined Income = Adjusted Gross Income + Nontaxable Interest + Half Your Social Security Benefits
Apply to taxation thresholds
For the purpose of illustration, let's assume the combined income for a joint filer is $75,000 and the Social Security benefits are $50,000.
| Taxation |
Single Filers |
Joint Filers |
| 0% |
less than $25,000 |
less than $32,000 |
| 50% |
between $25,000 and $34,000 |
between $32,000 and $44,000 |
| 85% |
more than $34,000 |
more than $44,000 |
The taxable amount for Socail Security benefits is the lesser of the following:
- 85% of Social Security benefits: 85% of $50,000 = $42,500
- 85% of the excess of combined income over $44,000 plus the smaller of $6,000 or 50% of Social Security benefits: 85% of ($75,000 - $44,000) + $6,000 = $32,350
