Best strategy to age 85
claim at 67
Based on annual earnings of $75,000, your AIME is estimated at $6,250/month, producing a PIA of $2,711/month at your Full Retirement Age of 67.
Claiming at 62 gives you a 30% permanent reduction. Delaying to 70 gives you a 24% permanent increase. The difference between the two strategies is $1,464/month.
Note: This is an estimate based on simplified PIA bend points. Your actual benefit depends on your complete 35-year earnings record. Create a my Social Security account at ssa.gov for your official estimate.
✗Claiming at 62 simply because you can
Fix:Claiming at 62 permanently reduces your benefit by up to 30%. Unless you have a health condition, need the income immediately, or expect a significantly below-average lifespan, the breakeven math usually favors waiting. Most people live well past the breakeven age of ~78–82.
✗Only considering your own benefit, not your spouse's
Fix:When the higher earner delays to 70, the surviving spouse receives that larger benefit for the rest of their life. For couples where one partner earns significantly more, this survivor benefit consideration often outweighs the individual breakeven calculation.
✗Not accounting for taxes on Social Security benefits
Fix:Up to 85% of Social Security is taxable if your combined income exceeds $34,000 (single) or $44,000 (married). Claiming earlier while drawing from taxable accounts can actually increase your lifetime tax burden. A Roth conversion strategy in pre-SS years often reduces this.
- 1The 'best' claiming age is rarely purely financial — health, spousal income, and the availability of other income sources all matter
- 2Use the SSA's my Social Security portal (ssa.gov) to get your official earnings record and actual benefit estimates
- 3If you have a pension, your Social Security may be reduced by the Windfall Elimination Provision (WEP) or Government Pension Offset (GPO)
- 4Consider doing Roth conversions in the years between retirement and SS claiming — your taxable income is low and you can reduce future RMDs

A Social Security benefits calculator estimates your monthly retirement benefit at different claiming ages — 62, your Full Retirement Age (FRA), and 70 — and shows you the breakeven age at which delaying starts paying off in total lifetime benefits. It uses the SSA's PIA (Primary Insurance Amount) bend-point formula, which applies declining percentage rates to your Average Indexed Monthly Earnings (AIME) to calculate your base benefit, then adjusts it up or down based on when you claim relative to your FRA.
Formula:
PIA = 90% × first $1,226 of AIME + 32% × AIME from $1,226–$7,391 + 15% × AIME above $7,391AIME is your highest 35-year average indexed monthly earnings. Claiming before FRA reduces your PIA by 5/9% per month for the first 36 months early and 5/12% per month beyond that. Delaying past FRA increases your PIA by 8% per year (2/3% per month) up to age 70. The result is a permanent adjustment that applies to every monthly check for the rest of your life.

- The difference between claiming at 62 vs. 70 can be $800–$1,500/month — a permanent gap that compounds over decades
- Most people claim too early: 62 is the most common claiming age despite rarely being optimal for those in good health
- Social Security is the only truly inflation-protected, longevity-insured income source most retirees have
- For married couples, the higher earner's claim decision directly determines the surviving spouse's benefit for life
- Delaying Social Security allows you to draw down savings earlier, potentially reducing RMDs and lifetime tax burden
- Every year you delay past FRA earns an 8% guaranteed return — better than any risk-free investment in most rate environments

Frequently Asked Questions
When should I start taking Social Security?
It depends on your health, other income, and life expectancy. Claiming at 62 means smaller monthly checks but more years of payments. Waiting until 70 means the largest possible check. The breakeven age — when delaying starts paying off total — is typically between 78 and 82. If you expect to live past 82, delaying is usually the better financial decision.
How is my Social Security benefit calculated?
The Social Security Administration averages your highest 35 years of indexed earnings to get your AIME (Average Indexed Monthly Earnings). It then applies a bend-point formula to your AIME to calculate your PIA (Primary Insurance Amount) — the benefit you receive at your Full Retirement Age. Claiming early reduces this; delaying increases it.
What is Full Retirement Age (FRA)?
FRA is the age at which you receive 100% of your Primary Insurance Amount. For anyone born in 1960 or later, FRA is 67. If you claim before FRA, your benefit is permanently reduced. If you delay past FRA up to age 70, your benefit increases by 8% per year.
Can I work and collect Social Security at the same time?
Yes, but if you claim before FRA, Social Security withholds $1 for every $2 you earn above $22,320 (2026 limit). In the year you reach FRA, the limit rises and the penalty decreases. Once you hit FRA, you can earn any amount without reduction. Withheld benefits are not lost — they're added back into your monthly payment once you reach FRA.
What is the COLA adjustment?
COLA (Cost-of-Living Adjustment) is an annual increase to Social Security benefits tied to inflation (the CPI-W index). In high-inflation years it can be 8–9%; in low-inflation years it may be 0–2%. This calculator lets you set an assumed COLA rate to model how your cumulative benefits grow over time.
What happens to my Social Security if I die early?
If you die before your spouse, your spouse may be eligible for a survivor benefit — up to 100% of your benefit if they've reached FRA. This means delaying your own claim can significantly increase your spouse's lifetime benefit too. Married couples should consider joint life expectancy when deciding when to claim.
