Social Security explained
Social Security provides monthly income to eligible retirees, survivors, and certain family members. Here’s what you need to know:
- Your benefit amount depends on your earning history and when you claim.
- Claiming benefits before full retirement age reduces your monthly payment, while delaying increases it.
- Benefits are funded by payroll taxes paid by workers and employers.
- Social Security should be one part of your retirement income strategy, alongside personal savings and investments.
What is Social Security?
Social Security is a federal government program that provides eligible recipients with guaranteed monthly income, adjusted for inflation. It primarily supports retirees, but other recipients include surviving spouses, dependent family members, and people with disabilities. Once you begin claiming retirement benefits, they last for the rest of your life. While Social Security isn’t meant to be your entire retirement solution, it plays a key role in helping you create a steady income stream in retirement.
According to the Social Security Administration, about 1 in 4 Americans over age 65 rely on Social Security for at least 90% of their income.1 On average, Social Security replaces about 40% of your annual pre-retirement earnings.2
Understand how to maximize your Social Security benefits
How does Social Security work?
Social Security operates as a pay-as-you-go system. While you work, you and your employer pay payroll taxes that fund benefits for today’s recipients. These taxes go into trust funds managed by the federal government, which are used to pay out benefits to current retirees, survivors, and eligible family members. Unlike retirement accounts such as IRAs or 401(k) plans, Social Security does not hold your contributions in a personal account for future withdrawal.
Who pays for Social Security?
Through payroll taxes, employees pay 6.2% of their wages toward Social Security, and employers match that with another 6.2%, up to an annual wage cap ($184,500 in 2026).3 If you’re self-employed, you pay both the employee and employer portions, totaling 12.4% of your net earnings, up to the wage cap.3 These contributions fund benefits for current recipients.
How Social Security taxes fund benefits:
- You and your employer each pay Social Security taxes on your earnings.
- These taxes are pooled into trust funds, not individual accounts.
- Current retirees and beneficiaries receive monthly payments from these funds.
- Future workers will fund your benefits when you retire.
- The system relies on a steady flow of contributions from the workforce to support retirees, survivors, and eligible family members.
How to stay focused on your retirement goals
How do you qualify for Social Security?
There are four main ways you can qualify for Social Security retirement benefits:
1. Your earnings history
You earn Social Security credits based on your work history. You need at least 40 credits to qualify, typically earned over 10 years of working. In 2026, you earn one credit for every $1,890 in earnings, up to four credits per year. Credits stay on your record permanently, so you can add more by continuing to work.
2. As a spouse
You may qualify for Social Security benefits based on your spouse’s earnings record, even if you’ve never worked in a job covered by Social Security. To receive spousal benefits, you must be at least 62 years old. If you claim before your full retirement age (FRA), your benefit will be reduced. If you never worked in a covered job, your FRA benefit equals 50% of your spouse’s primary insurance amount. However, you can’t collect spousal benefits until your spouse has claimed their own benefit.
3. As a surviving spouse
If your spouse worked and paid Social Security taxes, you may be eligible for survivor benefits when they pass away. In most cases, you must have been married for at least nine months. Your spouse must also have earned enough Social Security credits for survivor benefits, although the number required may depend on their age when they died. You can receive full benefits at your FRA or reduced benefits as early as age 60, as long as you did not remarry before then. Other situations, such as caring for minor children, may also qualify you.
4. As an ex-spouse
You might qualify for divorced spouse benefits if your marriage lasted at least 10 years, you’re currently unmarried, and your ex-spouse is at least 62 and qualifies for Social Security. If your ex-spouse hasn’t filed for benefits, you can still receive benefits if you’ve been divorced for at least two years.
What determines your benefits?
Your Social Security benefit amount is determined by several factors:
- Birth date: Determines your full retirement age (FRA), when you’re eligible for 100% of your benefit.
- Lifetime earnings: The Social Security Administration uses your 35 highest-earning years to calculate your benefit. Years with no earnings count as zeros.
- Start date: The age you start collecting benefits (anytime between 62 and 70) affects your monthly payment. Waiting longer increases your benefit. For example, if you were born in 1960 or later, your benefits look like this:
Social Security benefits by age
To collect Social Security, you must be at least 62 and have paid into the system for a minimum of 10 years. The amount you receive depends on your birth year and the age you start collecting. Your full retirement age (FRA) is when you’re eligible for 100% of your benefit. Claiming before or after your FRA will decrease or increase your monthly payment.

How to find out your Social Security benefits
You can estimate your future Social Security benefits by reviewing your Social Security statement. At ssa.gov you can access your statement, check your earnings history, and see estimates for claiming at different ages. Create a free account.
Social Security retirement income
For most Americans, Social Security is a significant source of retirement income. On average, benefits replace about 40% of pre-retirement income, but for many retirees, it’s an even larger share.1 The maximum benefit at full retirement age in 2026 is $4,152 per month. The age you claim benefits can make a difference of thousands of dollars over your lifetime. Delaying your claim increases your monthly payment by about 8% per year until age 70.
When should you claim Social Security?
Deciding when to claim Social Security is a personal decision that can have a lasting effect on your retirement income. Here’s how your claiming age affects your benefits:
Claiming before full retirement age
You can start collecting Social Security as early as age 62, but your monthly benefit will be permanently reduced. This may make sense if you need income sooner or have health concerns, but it means smaller payments for life.
Claiming at full retirement age
Claiming at your full retirement age (between 66 and 67, depending on your birth year) allows you to receive 100% of your benefit. This is the baseline amount calculated from your earnings history.
Delaying benefits
If you wait to claim Social Security after your full retirement age, your benefit increases by about 8% per year until age 70. Delaying can be a smart way to maximize your monthly income, especially if you expect to live longer or have other sources of income to draw from in the meantime.
Should you consider a Social Security break-even analysis?
A break-even analysis can help you decide when to start collecting Social Security. It calculates the point at which the total value of higher benefits (from delaying collection) exceeds the value of lower benefits taken earlier.
Let's say John is 61 and his full retirement age (FRA) is 67. He would receive the following monthly payments depending on his age:
Here are his break-even points for claiming at various ages, assuming a 2% cost-of-living adjustment:
- Age 77 if John claims at age 62 versus FRA
- Between ages 78 and 79 if John claims at age 62 versus age 70.
- Between ages 80 and 81 if John claims at FRA versus age 70.
In addition to a break-even analysis, consider your life expectancy, current health, family history, and your other income and assets in deciding when to collect Social Security.
Factors to consider before claiming Social Security
Before you decide when to claim Social Security, think about these important factors:
Retirement planning
Social Security should be part of your overall retirement strategy. Coordinate your benefits with other income sources, such as pensions, retirement accounts, and personal savings. If you can afford to wait, delaying Social Security can help maximize your lifetime benefits.
Marital status
Your marital status affects your claiming options. Married couples can coordinate timing to maximize household income. Divorced or surviving spouses may have additional benefit options. Consider your unique situation when planning.
Health history
Your health and family history of longevity can influence your decision. If you expect to live longer, delaying benefits may be more advantageous. If you have health concerns, claiming earlier may make sense.
Risk tolerance
Social Security provides guaranteed income, which can be especially valuable if you prefer less investment risk. Delaying benefits increases your monthly payment and provides inflation protection through cost-of-living adjustments.
Tax consequences
Social Security benefits may be taxable, depending on your total income. For individuals, up to 50% of benefits may be taxable if your provisional income exceeds $25,000, and up to 85% if it exceeds $34,000.4 For married couples filing jointly, the thresholds are $32,000 and $44,000. Consider how Social Security fits with your other taxable income sources.
Work status
If you claim benefits before your full retirement age and continue working, your benefits may be temporarily reduced if your earnings exceed certain limits. At full retirement age, Social Security will recalculate your benefit and increase your future monthly payments to give you credit for months in which benefits were withheld. After reaching full retirement age, you can work without affecting your Social Security payments.
What if you change your mind?
If you claim Social Security and then decide you no longer need the benefits, you have two options:
The “reset” rule
If you start collecting reduced benefits before your full retirement age, you can reset your benefits and erase the reduction by withdrawing your claim within 12 months and repaying all benefits received. When you reapply later, your benefit will be higher.
The voluntary suspension rule
If you started collecting reduced benefits before your full retirement age and missed the reset deadline, you can suspend your benefits once you reach full retirement age and restart them later. This allows your benefit to grow until you resume payments, up to age 70.
