Social Security is one part of retirement income, not the whole plan

Social Security replaces a portion of your pre-retirement earnings — typically 40% of what you earned before you stopped working, though this varies by how much you earned and when you claim. It is not designed to cover all your living costs in retirement. Most people need other income sources: savings, pensions, part-time work, or investments. Understanding what Social Security will actually pay you, and when, is the first step in building a realistic retirement budget.

The amount you receive depends on three things: how much you earned during your working years, how many years you worked, and what age you claim benefits. You can claim as early as 62 or as late as 70. Claiming earlier means smaller monthly payments for a longer period. Claiming later means larger monthly payments for a shorter period. The break-even point — where total lifetime benefits are roughly equal — falls around age 80 for most people, but your health, family history, and other income sources should all factor into your decision.

Key Takeaways

  • Social Security typically replaces about 40% of pre-retirement income, so you will need other sources to cover the rest of your living costs.
  • Your benefit amount is based on your 35 highest-earning years, so gaps in work history lower your payment.
  • You can claim between age 62 and 70, and claiming later increases your monthly payment by roughly 8% per year.
  • You can view your projected benefit amount on your Social Security account at ssa.gov, which updates annually.
  • Married couples, divorced people, and surviving family members may have additional claiming options that can increase household income.

How your benefit amount is calculated

The Social Security Administration calculates your benefit based on your 35 highest-earning years. If you worked fewer than 35 years, zeros are counted for the missing years, which lowers your average. Self-employed people, wage earners, and government employees all contribute through payroll taxes, though some government pensions have different rules.

Your earnings record is adjusted for inflation, so older years of work are not penalized just because wages were lower decades ago. The agency then applies a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings — this is why Social Security is more valuable to lower-income workers than to higher-income workers.

You can view your own earnings record and projected benefit amount by creating an account at ssa.gov. The site shows what you would receive if you claimed at 62, at your full retirement age (which ranges from 66 to 67 depending on birth year), and at 70. This estimate updates once per year, usually in September or October.

When you can claim and how it affects your payment

Your full retirement age — the age at which you receive 100% of your calculated benefit — depends on your birth year. For people born in 1943 or later, it ranges from 66 to 67. You can claim as early as 62, but your payment will be permanently reduced by roughly 25% to 30%. You can also delay claiming until 70, which increases your payment by roughly 8% per year beyond your full retirement age.

The reduction or increase is permanent. If you claim at 62 and live to 95, you will have received more total money than if you had claimed at 70 and lived to 95 — but your monthly payment will always be smaller. If you claim at 70, your monthly payment will always be larger, but you will have foregone payments for eight years.

There is no "best" age to claim. The right choice depends on your health, your family history of longevity, whether you have other income, and whether you need the money now. Someone in poor health or with limited savings might claim at 62. Someone in good health with other income might wait until 70.

Spousal and survivor benefits

If you are married, your spouse may be able to claim a benefit based on your earnings record, even if they did not work or worked very little. A spouse can receive up to 50% of your full retirement age benefit if they claim at their own full retirement age, or a reduced amount if they claim earlier. This is true whether your spouse is younger or older than you.

If you are divorced and were married for at least 10 years, you may be able to claim on your ex-spouse's record without affecting their benefits or your ex's ability to claim. You must be at least 62 and unmarried. The benefit is calculated the same way as a spousal benefit.

If you die, your surviving spouse, children under 19 (or 19 if still in high school), and dependent parents may receive survivor benefits based on your earnings record. These benefits do not reduce your own benefit if you are still living — they are paid from the Social Security trust fund. A surviving spouse can claim as early as 60, or at 50 if caring for a child under 16.

How work affects your benefits before full retirement age

If you claim Social Security before your full retirement age and continue to work, your benefit will be temporarily reduced if your earnings exceed a certain threshold. For 2024, the limit is $23,400 per year (this amount changes annually). For every $2 you earn above the limit, $1 is withheld from your benefit.

The reduction applies only in years before you reach your full retirement age. Once you reach full retirement age, you can earn any amount without penalty. The withheld benefits are not lost — your payment is recalculated at full retirement age to account for the months you did not receive benefits, so you receive a slightly higher payment going forward.

This rule affects many people who retire early and then take part-time work, or who were not sure they wanted to retire fully. If you are considering claiming before full retirement age and continuing to work, check the current earnings limit on ssa.gov before you decide.

Taxes on Social Security benefits

Depending on your total income, a portion of your Social Security benefits may be subject to federal income tax. This is not an additional tax — it is ordinary income tax applied to part of your benefit. The amount taxed depends on your "combined income," which includes your adjusted gross income, tax-exempt interest, and half of your Social Security benefits.

If you are single and your combined income is below $25,000, none of your benefits are taxed. Between $25,000 and $34,000, up to 50% of your benefits may be taxed. Above $34,000, up to 85% may be taxed. For married couples filing jointly, the thresholds are $32,000 and $44,000.

These thresholds have not changed since 1984, so more people are affected now than in the past. If you have other retirement income — from pensions, investments, or part-time work — you may owe tax on part of your Social Security. A tax professional or the IRS can help you estimate this before you retire.

Building a complete retirement budget

Social Security is a foundation, not a complete retirement plan. Start by finding out what you will receive — check your ssa.gov account for your projected benefit. Then list your other income sources: pensions, savings, rental income, part-time work, or investment withdrawals. Add these together to see whether the total covers your expected living costs.

If the total falls short, you have several options: work longer (which increases your Social Security benefit and gives you more time to save), save more before you retire, plan to spend less in retirement, or delay claiming Social Security to increase your monthly payment. If you have a spouse, consider both of your benefits and claiming strategies together, since the decisions are linked.

Many people find it helpful to work with a financial planner or tax professional who can model different claiming ages and income sources. Some nonprofits and senior centers also offer free or low-cost retirement planning workshops. The goal is to have a realistic picture of your income and expenses before you stop working, not to discover a shortfall after you have already claimed.

Frequently Asked Questions

Can I change my mind after I claim Social Security?

Yes, but only within a limited window. If you claimed within the past 12 months, you can withdraw your claim and reapply later at a higher age. You must repay all benefits you received. After 12 months, you cannot withdraw, but you can suspend your benefits at full retirement age and let them grow until 70 — your payment increases 8% per year during the suspension.

What happens to my benefits if I move out of the country?

You can receive Social Security benefits while living abroad in most countries. However, some countries have restrictions, and you must notify the Social Security Administration if you move. Contact the agency before you leave to confirm your specific situation and to arrange how you will receive payments.

How much should I have saved before I retire?

This depends on your expected lifespan, your living costs, and your Social Security benefit. A common rule of thumb is to have 25 times your annual spending saved, though this varies widely. Use your projected Social Security benefit to calculate how much additional income you need each year, then work backward to estimate how much you should save.

Does my spouse's work history affect my benefit?

No. Your benefit is based only on your own earnings record. Your spouse's benefit is based on their own record, or on yours if that is higher. You each have separate accounts, though married couples can coordinate their claiming strategies to maximize household income.

What if I never worked or worked very few years?

You may still receive a benefit based on a spouse's or ex-spouse's earnings record if you meet the requirements (married at least 10 years for ex-spouse, currently married for spouse, age 62 or older). If you have no work history and no may be able to access spouse, you would not receive Social Security, but you may be able to access other assistance programs.
