Social Security Benefit Estimator
Approximate your monthly benefit at every claiming age from 62 to 70, and see the breakeven age where waiting to claim pays off — the chart that decides the whole question.
| Group | Monthly benefit |
|---|---|
| 62 | $2,066 |
| 63 | $2,213 |
| 64 | $2,361 |
| 65 | $2,557 |
| 66 | $2,754 |
| 67 | $2,951 |
| 68 | $3,187 |
| 69 | $3,423 |
| 70 | $3,659 |
Cumulative lifetime benefits: claiming at 62 leads early, but claiming at 70 overtakes it around age 80.4. Living past the breakeven favors claiming later.
Claiming later pays more per month but starts later; the lines cross at the breakeven age. Living past it favors delaying; not living that long favors claiming early.

How the Social Security estimator works
Social Security is the backbone of most retirement plans — inflation-adjusted income that lasts as long as you do — yet its formula is opaque enough that many people have no idea what to expect. This tool builds a rough estimate the same way the Social Security Administration does in outline: it projects your earnings history, averages your best years, runs them through the benefit formula, and then adjusts for the age you choose to claim.
Two visuals do the heavy lifting. The first shows your estimated monthly benefit at every claiming age from 62 to 70, so you can see the steep price of claiming early and the reward for waiting. The second — the one worth sharing — is the breakeven chart: it tracks cumulative lifetime benefits for claiming early versus late and marks the age where waiting pulls ahead. That crossover is the crux of the entire claiming decision.
Before going further, the essential caveat: this is an approximation, and you should verify it. Your actual record, complete with each year’s real earnings and wage indexing, lives in your my Social Security account, and the SSA’s own official estimator is the authoritative source. Use this page to build intuition, then confirm the numbers there.
The math, stated plainly
The formula runs in three steps. First, your 35 highest earning years (capped each year at the taxable maximum) are averaged and divided by 12 to get your average indexed monthly earnings (AIME). Second, the AIME passes through the progressive bend-point formula to produce your primary insurance amount:
- 90% of the first slice of AIME,
- 32% of the slice up to the second bend point,
- 15% of anything above it.
That progressive structure is why lower earners get a higher percentage of their income replaced. Third, the claiming adjustment applies: a permanent reduction of up to 30% for claiming at 62, no adjustment at full retirement age, and delayed credits of about 8% per year up to 70. Multiply the PIA by that factor and you have your estimated monthly check.
Every input, explained
Current annual earnings
Your present gross salary, which anchors the projected earnings record. Because benefits are based on lifetime earnings, this is a strong driver of the estimate, though the progressive formula softens the effect at higher incomes.
Age and age you started working
These set how many working years feed the top-35 average. Someone who started at 22 has more years to fill that record than someone who started at 30, which can lift the average by crowding out zero-earning years.
Earnings growth
The average annual raise used to project your salary backward to your first working year and forward to full retirement age. It shapes the earnings history and therefore the AIME.
Claiming age
The single biggest lever you control. Moving it from 62 to 70 can increase your monthly benefit by more than three-quarters. The right choice depends on your health, your other income, and how long you expect to live.
Assumptions and limitations
- Simplified earnings history. A single smooth projection, not your real year-by-year record.
- No wage indexing. Past years are not indexed to historical wage levels, and each year is capped at the current taxable maximum.
- Individual only. Spousal, survivor, and divorced-spouse benefits — often substantial — are not modeled.
- Ignores WEP/GPO and taxation. Special provisions and the taxation of benefits can change the real figure.
Putting it together
Your Social Security estimate is not a standalone answer — it is an input to the bigger plan. Enter it as guaranteed income in the retirement calculator to see how much it reduces what your savings must cover. Because it lets you draw down investments more slowly, it directly affects your safe withdrawal rate. And the savings it supplements are built, for most people, in a 401(k) over a working career.
Frequently asked questions
- How is my Social Security benefit calculated?
- Your benefit is based on your highest 35 years of earnings, indexed for wage growth, averaged into a monthly figure called your AIME. A progressive formula with “bend points” converts that into your primary insurance amount (PIA) — the benefit at full retirement age. Claiming earlier or later then adjusts that amount down or up.
- Why is this estimate only an approximation?
- It projects a single smooth earnings history from your current salary, caps each year at the current taxable maximum rather than each year’s historical value, and does not apply official wage indexing. It also ignores spousal and survivor benefits, the WEP/GPO provisions, and taxation of benefits. Treat it as a ballpark; your Social Security statement is the real answer.
- What is full retirement age?
- Full retirement age (FRA) is when you can claim 100% of your primary insurance amount. For anyone born in 1960 or later it is 67. Claim before FRA and your monthly benefit is permanently reduced; claim after and it is permanently increased, up to age 70.
- How much less do I get by claiming at 62?
- For an FRA of 67, claiming at the earliest age of 62 permanently reduces your monthly benefit to about 70% of your PIA — a roughly 30% cut. The reduction is steepest in the first three years before FRA and slightly gentler beyond that. It lasts for life, though it may be partly offset by receiving benefits for more years.
- How much more do I get by waiting until 70?
- Delaying past full retirement age earns delayed retirement credits of about 8% per year until age 70. Waiting from 67 to 70 raises your monthly benefit by roughly 24%. There is no advantage to delaying beyond 70, so 70 is the practical maximum.
- What is the breakeven age for claiming later?
- The breakeven is the age at which the larger checks from claiming late catch up to the head start of claiming early, in cumulative dollars. It typically lands in the early-to-mid 80s. If you expect to live past it, delaying usually wins on total lifetime benefits; if not, claiming earlier can come out ahead.
- Should I always wait until 70?
- Not necessarily. Delaying maximizes the monthly amount and is valuable longevity insurance, but claiming earlier can make sense if you have health concerns, need the income, or want to let other assets keep growing. It is a personal trade-off between a larger guaranteed check and having money sooner.
- Does working longer increase my benefit?
- It can, in two ways: additional high-earning years can replace lower-earning years in your top 35, and higher career earnings raise your average. But because the formula is progressive and caps taxable earnings, the increase from extra years is often modest for people who already have a full 35-year record.
- Are Social Security benefits taxed?
- They can be. Depending on your total income, up to 85% of your benefits may be subject to federal income tax, and some states tax them too. This calculator shows gross benefits and does not model that taxation, so your spendable amount may be lower.
- How should I use this number in my retirement plan?
- Treat it as expected guaranteed income that reduces how much your savings must provide. Enter it as “other income” in the retirement calculator, or subtract it from your spending needs when setting a withdrawal rate. Because it is inflation-adjusted and lasts for life, it is one of the most valuable pieces of most retirement plans.
