Free Social Security benefit estimator. Calculate your PIA from AIME using 2025 bend points, then see how claiming age (62-70) affects your monthly benefit. Includes spousal and survivor estimates.
The Social Security Benefit Estimator calculates your Primary Insurance Amount (PIA) based on your average earnings history and shows how your monthly benefit changes depending on when you claim (ages 62-70). The calculation uses 2025 bend points and reduction/delayed retirement credit factors.
Social Security is the foundation of most Americans' retirement income, replacing about 40% of pre-retirement earnings for average earners. Deciding when to claim is one of the most impactful financial decisions you'll make — the difference between claiming at 62 vs 70 can be over 75%.
Enter your average annual earnings (or estimated AIME) to see your projected benefit at every claiming age. Social Security benefits depend on your 35 highest-earning years, your claiming age, and whether you continue working past full retirement age. The difference between claiming at 62, full retirement age, and 70 can amount to tens of thousands of dollars in cumulative benefits over your lifetime.
Claiming Social Security at the wrong age can cost tens of thousands of dollars in lifetime benefits. This estimator shows the trade-offs at every age so you can make an informed decision based on your health, financial needs, and life expectancy. Running multiple scenarios empowers you to choose the claiming age that maximizes lifetime income based on your personal circumstances.
AIME = Average of top 35 years of indexed earnings ÷ 12 PIA = 90% × first $1,174 + 32% × ($1,174 to $7,078) + 15% × above $7,078 (2025 bend points) Early claiming: PIA reduced 5/9% per month for first 36 months, 5/12% per additional month Delayed credits: PIA increased 2/3% per month (8%/year) from FRA to 70
Result: PIA: $2,576/mo at 67 | $1,804 at 62 | $3,194 at 70
At $75K average annual earnings, your AIME is $6,250. The PIA formula yields ~$2,576/month at FRA 67. Claiming at 62 (60 months early) reduces it to $1,804 (30% reduction). Waiting to 70 adds 24% for $3,194.
The PIA formula for 2025 uses bend points of $1,174 and $7,078. The first $1,174 of AIME is replaced at 90%, the next $5,904 at 32%, and everything above $7,078 at 15%. This progressive structure means lower earners get a higher replacement rate. The maximum PIA in 2025 is approximately $4,018 at FRA of 67.
The decision comes down to: do you need the money now, or can you afford to wait? Claiming at 62 gives you 8 extra years of payments but at a permanently reduced rate. Claiming at 70 gives you the maximum benefit but zero payments from 62-69. The break-even age is typically 78-82 — if you live past that, delaying wins.
The higher earner's claiming decision affects the surviving spouse. If the higher earner waits until 70, the survivor benefit is also maximized. This makes delayed claiming especially valuable for couples where one spouse has significantly higher earnings.
PIA is your monthly Social Security benefit at your Full Retirement Age (FRA). It's calculated from your Average Indexed Monthly Earnings (AIME) using a progressive formula with "bend points." Claiming before FRA reduces the PIA; claiming after increases it.
FRA is 66 for those born 1943-1954, gradually increasing to 67 for those born 1960 or later. If born 1955: 66 and 2 months. 1956: 66 and 4 months, etc. Claiming at FRA gives you 100% of your PIA.
For FRA 67: Benefits are reduced by approximately 30% at age 62. The reduction is 5/9 of 1% per month for the first 36 months before FRA, and 5/12 of 1% per additional month. For FRA 66, the reduction at 62 is about 25%.
For each month you delay claiming past FRA (up to age 70), your benefit increases by 2/3 of 1% per month, or 8% per year. From FRA 67 to age 70. that's a 24% increase. There's no benefit to delaying past age 70.
A spouse can claim up to 50% of the higher earner's PIA at the spouse's FRA. Spousal benefits do not earn delayed retirement credits past FRA. To qualify, you must be married for at least 1 year (or have a qualifying child).
AIME averages your 35 highest-earning years (indexed for wage growth), then divides by 420 (35 years × 12 months). If you worked fewer than 35 years, zeros fill the remaining years. Higher-earning years boost your AIME and therefore your PIA.
