Retirement Income
Social Security Calculator
Estimate your monthly Social Security benefit and find the optimal claiming age. Compare claiming at 62, 67, or 70 — and see exactly when later claiming pays off.
How the Social Security calculator works
Social Security retirement benefits are calculated from your Average Indexed Monthly Earnings (AIME) — the average of your 35 highest-earning years, adjusted for wage inflation. The Social Security Administration (SSA) applies a progressive formula using "bend points" to convert your AIME into your Primary Insurance Amount (PIA)— the monthly benefit you'd receive if you claim exactly at your full retirement age (67 for anyone born in 1960 or later).
This calculator uses your current annual income as a proxy for your career earnings. It applies the 2024 bend-point formula: 90% of the first $1,174 of AIME, 32% of the next portion up to $7,078, and 15% of anything above. The result is your estimated PIA, which is then adjusted up or down based on your chosen claiming age.
Claiming age adjustments
Your full retirement age (FRA) is the baseline — claiming at exactly 67 gives you 100% of your PIA. Every month you claim before 67, your benefit is permanently reduced:
- First 36 months before FRA: benefit reduced 5/9 of 1% per month (≈6.67%/year)
- Beyond 36 months before FRA: reduced 5/12 of 1% per month (≈5%/year)
- Claiming at 62 (maximum early): benefit reduced by ~30% vs claiming at 67
For every month you delay past FRA, your benefit increases by 2/3 of 1% per month (8%/year), up to a maximum of 24% extra at age 70. After 70, there is no further increase — there's no benefit to waiting beyond your 70th birthday.
The break-even calculation
Because delaying pays more per month but you collect for fewer years, there's a break-even age where the higher delayed benefit catches up with what early claimers have already collected. For most people comparing claiming at 62 versus 70, the break-even is around age 80–82. If you expect to live past that age, delaying is generally advantageous. If you have serious health concerns or need the income, claiming earlier may make sense.
Worked example
Consider a 50-year-old earning $80,000/year. Their estimated AIME (using current income) is approximately $6,667/month. Applying the 2024 bend-point formula: 90% × $1,174 + 32% × ($6,667 − $1,174) = $1,057 + $1,758 = approximately $2,815/month PIA at age 67.
- Claiming at 62: ~$1,969/month (70% of PIA)
- Claiming at 67: ~$2,815/month (100% of PIA)
- Claiming at 70: ~$3,494/month (124% of PIA)
Break-even between 62 and 70 is around age 81. If this person lives to 85, they'll collect roughly $170,000 more by waiting until 70 than by claiming at 62.
Spousal and survivor benefits
Married individuals can claim a spousal benefit of up to 50% of their spouse's PIA if that's larger than their own earned benefit. Widows and widowers can claim a survivor benefit of up to 100% of a deceased spouse's benefit. These rules add complexity beyond this calculator — for spousal benefit optimization, consider consulting a financial planner or the SSA's website directly.
Key concepts
- AIME — Average Indexed Monthly Earnings
- The SSA takes your 35 highest-earning years, adjusts each for wage inflation, sums them, and divides by 420 (35 × 12 months). If you have fewer than 35 working years, zero-income years are included — this can significantly reduce your AIME and benefit.
- PIA — Primary Insurance Amount
- Your PIA is the benefit you receive if you claim at exactly your full retirement age. It's the baseline from which early-claiming reductions and delayed-retirement credits are applied.
- COLA — Cost-of-Living Adjustment
- Once you start collecting, your benefit is adjusted annually for inflation based on the CPI-W index. The average COLA over the past decade has been about 2.5%, though it reached 8.7% in 2023 due to high inflation.
- Delayed retirement credits
- For every year you delay claiming past your full retirement age (up to age 70), your benefit permanently increases by 8%. This is a guaranteed, inflation-adjusted return that's hard to beat with most investment strategies.
Frequently asked questions
When should I claim Social Security?
The optimal claiming age depends on your health, financial need, and whether you're married. Healthy individuals with no immediate income need should generally delay to 70 for the maximum benefit. Those with health concerns or who need income sooner may prefer to claim at 62 or 67. Married couples often benefit from having the higher earner delay to 70 to maximize the survivor benefit.
What is the full retirement age (FRA)?
67 for anyone born in 1960 or later. For those born between 1943 and 1959, FRA gradually increases from 66. You can find your exact FRA on the SSA website or by requesting your Social Security statement at ssa.gov/myaccount.
How accurate is this estimate?
This calculator uses a simplified version of the SSA formula based on your current income. Your actual benefit depends on your full 35-year earnings history. For a personalized, official estimate, create an account at ssa.gov/myaccount — the SSA updates projections annually based on your actual earnings record.
Does working longer increase my benefit?
Yes, in two ways. First, additional working years replace lower-earning years in your 35-year average, raising your AIME. Second, working until 70 enables you to earn delayed retirement credits. If you have fewer than 35 working years, each additional year of work also replaces a zero-income year, which can significantly raise your benefit.
What happens if Social Security runs out of money?
The Social Security trust fund faces projected depletion around 2033 without legislative action. At that point, incoming payroll taxes would cover approximately 77–80% of scheduled benefits. This calculator models current scheduled benefits — for conservative planning, some advisors recommend modeling a 20–25% reduction after 2033. Congress has historically avoided cuts to current and near-retirees.
